CSCS Health, Safety and Environment Test — Questions and Answers

Question 1: What is the purpose of a PPE compatibility assessment?

To ensure that multiple items of PPE can be worn together without reducing the protection of any item (Correct answer)
To check if PPE matches the company uniform
To compare PPE prices from different suppliers
To check if PPE is the same colour

Correct answer: To ensure that multiple items of PPE can be worn together without reducing the protection of any item

When workers need to wear multiple items of PPE simultaneously (e.g., hard hat, ear defenders, and safety glasses), a compatibility assessment ensures they can all be worn together without reducing the effectiveness of any item.

Question 2: Why is it important that PPE fits the individual worker correctly?

Ill-fitting PPE may not provide adequate protection and may create additional hazards (Correct answer)
For appearance only
To reduce costs
It is a legal requirement for aesthetics

Correct answer: Ill-fitting PPE may not provide adequate protection and may create additional hazards

PPE that does not fit correctly will not provide the intended level of protection. For example, a loose-fitting respirator will allow contaminants to bypass the filter, and oversized gloves may catch in machinery.

Question 3: What is a fire risk assessment and when must it be carried out?

A fire brigade inspection
A building regulation approval
A systematic evaluation of fire hazards and risks that must be carried out before work starts and reviewed regularly (Correct answer)
An insurance valuation done every 5 years

Correct answer: A systematic evaluation of fire hazards and risks that must be carried out before work starts and reviewed regularly

Under the RR(FS)O 2005, a fire risk assessment must identify fire hazards, people at risk, evaluate the risks, record significant findings, and plan emergency procedures. It must be carried out before occupation and reviewed regularly or when changes occur.

Question 4: What is the purpose of an edge protection system on a flat roof?

To improve the appearance of the building
To support solar panels
To prevent workers and materials from falling from the roof edge (Correct answer)
To act as a handrail for visitors

Correct answer: To prevent workers and materials from falling from the roof edge

Edge protection systems on flat roofs are collective fall prevention measures that prevent workers, tools, and materials from falling from the roof edge. They are preferred over personal fall protection as they protect all workers simultaneously.

Question 5: What is the purpose of a construction site sign-in/sign-out system?

To calculate overtime payments
To maintain an accurate record of all persons on site for emergency evacuation purposes and site security (Correct answer)
To monitor tea break times
To track the delivery of materials

Correct answer: To maintain an accurate record of all persons on site for emergency evacuation purposes and site security

A sign-in/sign-out system ensures an accurate record of all persons present on site at any time. This is critical for emergency situations (fire, structural collapse) where an accurate headcount at the muster point can confirm whether everyone has evacuated safely. It also supports site security and access control.

Question 6: What is the maximum recommended wind speed at which work at height should normally be stopped?

40 mph
17 mph
50 mph
23 mph (Force 6) (Correct answer)

Correct answer: 23 mph (Force 6)

HSE guidance recommends that work at height should generally be stopped when wind speeds reach 23 mph (Force 6 on the Beaufort scale), though this may vary depending on the specific task and equipment being used.

Question 7: What method should be used for backfilling an excavation that runs adjacent to an existing building foundation?

Rapid backfilling with any available material using heavy plant
The excavation can be left open indefinitely if it is fenced
Controlled backfilling in compacted layers using approved granular material to avoid settlement or damage to the adjacent foundation (Correct answer)
Backfilling is not required if the excavation is shallow

Correct answer: Controlled backfilling in compacted layers using approved granular material to avoid settlement or damage to the adjacent foundation

Backfilling near existing foundations must be carried out carefully in compacted layers (typically 150-300mm) using suitable granular material to prevent future settlement. Uncontrolled backfilling can cause ground movement affecting adjacent structures. The method must be specified in the method statement under CDM Regulations 2015, and a structural engineer may need to approve the approach.

Question 8: How often should RPE (Respiratory Protective Equipment) face-fit testing be carried out?

At initial issue and repeated when there are changes to the wearer's face or the RPE model (Correct answer)
Face-fit testing is not required
Once when first issued
Every 5 years

Correct answer: At initial issue and repeated when there are changes to the wearer's face or the RPE model

RPE face-fit testing should be carried out at initial issue and whenever there are changes that could affect the seal, such as significant weight change, dental work, or facial scarring. It should also be repeated if the RPE model changes.

Question 9: What is a Waste Transfer Note and when is it required on a construction site?

It is only required for hazardous waste
A Waste Transfer Note must accompany every transfer of non-hazardous controlled waste and must include a description of the waste, the quantity, the carrier's details, and the destination — it must be kept for at least 2 years (Correct answer)
It is only required when waste leaves the country
It is a voluntary document

Correct answer: A Waste Transfer Note must accompany every transfer of non-hazardous controlled waste and must include a description of the waste, the quantity, the carrier's details, and the destination — it must be kept for at least 2 years

Under Section 34 of the Environmental Protection Act 1990 and the Waste (England and Wales) Regulations 2011, a Waste Transfer Note (WTN) must be completed for every transfer of non-hazardous waste. It must include a written description of the waste, SIC code, quantity, container type, and details of both parties. WTNs must be retained for a minimum of 2 years. Hazardous waste requires consignment notes kept for 3 years.

Question 10: Which of the following activities on a construction site would typically require a COSHH assessment?

Walking across level ground
Carrying timber by hand
Mixing cement or cutting concrete blocks (Correct answer)
Using a tape measure

Correct answer: Mixing cement or cutting concrete blocks

Mixing cement exposes workers to cement dust (containing hexavalent chromium, a skin sensitiser) and wet cement (alkaline, causes burns). Cutting concrete generates respirable crystalline silica dust. Both activities require a COSHH assessment to identify hazards and implement controls such as LEV, water suppression, and appropriate PPE.

Question 11: What voltage supply is required for portable electrical equipment used on construction sites under BS 7671?

12V extra-low voltage only
110V via centre-tapped earth transformer (Correct answer)
230V via standard socket
415V three-phase supply

Correct answer: 110V via centre-tapped earth transformer

BS 7671 and HSE guidance require 110V supply via a centre-tapped earth transformer for portable tools on construction sites. This limits the maximum voltage to earth to 55V, significantly reducing the risk of fatal electric shock.

Question 12: What is the primary purpose of a Residual Current Device (RCD) on a construction site?

To regulate voltage fluctuations
To detect earth leakage current and disconnect the supply rapidly (Correct answer)
To monitor energy consumption
To prevent overloading of circuits

Correct answer: To detect earth leakage current and disconnect the supply rapidly

An RCD detects an imbalance between live and neutral conductors caused by earth leakage current and disconnects the supply within milliseconds. Under the Electricity at Work Regulations 1989, RCDs provide additional protection against electric shock but are not a substitute for reduced voltage systems.

Question 13: What type of respiratory protective equipment (RPE) must be used during licensed asbestos removal work?

Powered air-purifying respirator (PAPR) or full-face air-fed breathing apparatus, face-fit tested to the individual wearer, with an assigned protection factor appropriate to the expected exposure level (Correct answer)
RPE is not required inside a full enclosure
A simple disposable FFP3 dust mask
Any mask labelled as a dust mask

Correct answer: Powered air-purifying respirator (PAPR) or full-face air-fed breathing apparatus, face-fit tested to the individual wearer, with an assigned protection factor appropriate to the expected exposure level

Licensed asbestos removal requires RPE with a high assigned protection factor (APF) — typically a full-face powered air-purifying respirator (APF 40) or air-fed full-face mask (APF 40). The RPE must be individually face-fit tested for each wearer. Simple disposable FFP3 masks (APF 20) are generally not sufficient for licensed removal work. The type of RPE is specified in the plan of work.

Question 14: During what hours are construction sites typically permitted to carry out noisy work in residential areas under local authority controls?

There are no restrictions on construction noise
24 hours a day, 7 days a week
Typically Monday to Friday 08:00-18:00, Saturday 08:00-13:00, with no noisy work on Sundays or Bank Holidays — though exact hours vary by local authority (Correct answer)
Only between midnight and 6am

Correct answer: Typically Monday to Friday 08:00-18:00, Saturday 08:00-13:00, with no noisy work on Sundays or Bank Holidays — though exact hours vary by local authority

Under Section 60 and 61 of the Control of Pollution Act 1974, local authorities can impose conditions on construction site noise including permitted working hours. While hours vary by authority, the typical standard is Monday to Friday 08:00-18:00, Saturday 08:00-13:00, with no noisy work on Sundays or Bank Holidays. Prior consent under Section 61 can be sought for work outside these hours.

Question 15: What is the correct order of the waste hierarchy as defined by the Waste (England and Wales) Regulations 2011?

Recycle, reuse, dispose, recover, prevent
There is no legally defined order for waste management
Prevention, reuse, recycling, other recovery (e.g. energy recovery), and disposal — in descending order of preference (Correct answer)
Dispose, recover, recycle, reuse, prevent

Correct answer: Prevention, reuse, recycling, other recovery (e.g. energy recovery), and disposal — in descending order of preference

The Waste (England and Wales) Regulations 2011 implement the EU Waste Framework Directive and establish the waste hierarchy in order of preference: prevention (avoiding waste creation), preparing for reuse, recycling, other recovery (such as energy recovery), and disposal (landfill) as the last resort. Construction sites must demonstrate compliance with this hierarchy.

Question 16: What is the 'power zone' in manual handling?

The electrical supply area
The area between the shoulders and knees, close to the body, where lifting is most efficient (Correct answer)
The area where power tools are stored
The strongest part of the load

Correct answer: The area between the shoulders and knees, close to the body, where lifting is most efficient

The power zone (also called the comfort zone) is the area between mid-thigh and mid-chest height, close to the body. Lifting within this zone uses the strongest muscles and maintains the best posture, reducing injury risk.

Question 17: What is the required safe working distance that must be maintained between the edge of an excavation and heavy plant operating alongside it?

50cm is always sufficient
The distance depends on the depth of excavation and soil type but is typically at least equal to the depth of the trench to prevent surcharge loading and edge collapse (Correct answer)
Heavy plant can operate right at the edge if the operator is experienced
No minimum distance is required

Correct answer: The distance depends on the depth of excavation and soil type but is typically at least equal to the depth of the trench to prevent surcharge loading and edge collapse

There is no single fixed distance — it depends on the excavation depth, soil type, and weight of the plant. As a general rule, heavy plant should operate at a distance at least equal to the depth of the excavation from the edge. The competent person must assess the surcharge loading and specify a safe distance. CDM Regulations 2015 require this to be included in the construction phase plan.

Question 18: Under the Control of Asbestos Regulations 2012, who has the 'duty to manage' asbestos in non-domestic premises?

The building's tenants
The HSE directly manages all asbestos in buildings
The local council environmental health officer
The dutyholder — typically the owner, occupier, or anyone with responsibility for maintenance or repair of the premises (Correct answer)

Correct answer: The dutyholder — typically the owner, occupier, or anyone with responsibility for maintenance or repair of the premises

Regulation 4 of the Control of Asbestos Regulations 2012 places the 'duty to manage' asbestos on the dutyholder, defined as the person who has an obligation by contract or tenancy to maintain or repair the premises, or if no such person exists, the person in control of the premises. This duty includes identifying asbestos-containing materials, assessing their condition, and managing the risk.

Question 19: A construction worker has a chemical burn from wet cement. What is the correct first aid treatment?

Brush off dry cement, then irrigate with large amounts of clean water for at least 20 minutes (Correct answer)
Wrap the area in cling film without washing
Apply a dry dressing immediately
Apply neutralising cream

Correct answer: Brush off dry cement, then irrigate with large amounts of clean water for at least 20 minutes

For chemical burns from wet cement, you should first brush off any dry cement, then irrigate the affected area with copious amounts of clean water for at least 20 minutes. Cement is highly alkalite and causes deep burns if not removed promptly. This should be followed by medical attention.

Question 20: What is the difference between a fire exit and an emergency exit?

They are the same thing (Correct answer)
A fire exit is used during fire evacuation and may be kept locked with panic hardware; an emergency exit is for any emergency
Fire exits are larger
Emergency exits have no signs

Correct answer: They are the same thing

In practice, the terms are often used interchangeably in the UK. Both refer to exits designated for use in emergencies, equipped with panic hardware and appropriate signage. The key requirement is that they can be opened easily and immediately in an emergency.

Question 21: What are the requirements for managing asbestos waste as part of environmental compliance on a demolition project?

Asbestos waste must be kept completely separate from other waste, double-wrapped in labelled bags or sheeting, transported by a specialist registered carrier with hazardous waste consignment notes, and disposed of at a licensed hazardous waste landfill cell (Correct answer)
Asbestos waste can be mixed with general demolition waste
Asbestos waste management is optional
Asbestos can be buried in the site foundations

Correct answer: Asbestos waste must be kept completely separate from other waste, double-wrapped in labelled bags or sheeting, transported by a specialist registered carrier with hazardous waste consignment notes, and disposed of at a licensed hazardous waste landfill cell

Asbestos waste is classified as hazardous waste under the Hazardous Waste Regulations 2005. It must be completely segregated from other demolition waste, double-wrapped in labelled asbestos waste packaging (red-striped bags or 1000-gauge polythene), accompanied by hazardous waste consignment notes, transported by a specialist registered carrier, and disposed of at a landfill site with a specific asbestos cell. Mixing asbestos with general waste is a criminal offence.

Question 22: What is the upper exposure action value under the Control of Noise at Work Regulations 2005?

90 dB(A)
83 dB(A)
85 dB(A) (Correct answer)
80 dB(A)

Correct answer: 85 dB(A)

The upper exposure action value is 85 dB(A) daily or weekly personal noise exposure. At this level, employers must ensure hearing protection is worn, designate hearing protection zones, and take additional steps to reduce noise exposure.

Question 23: What is the significance of fire stopping in construction?

It refers to the fire brigade stopping a fire
It is a type of fire alarm
It stops construction work during a fire
It seals gaps and openings in fire-resistant structures to prevent fire and smoke from spreading through them (Correct answer)

Correct answer: It seals gaps and openings in fire-resistant structures to prevent fire and smoke from spreading through them

Fire stopping involves sealing penetrations, joints, and gaps in fire-resistant walls and floors (around pipes, cables, ducts) to maintain the fire compartment's integrity and prevent fire and smoke from spreading through these openings.

Question 24: How often must fire extinguishers be serviced under BS 5306?

Only when used
Annually by a competent person, with a more detailed extended service at specific intervals (Correct answer)
Monthly
Every 5 years

Correct answer: Annually by a competent person, with a more detailed extended service at specific intervals

Under BS 5306-3, fire extinguishers must receive an annual basic service by a competent person. Extended services are required at specific intervals depending on the extinguisher type (e.g., every 5 years for water and foam).

Question 25: What action is required under the Electricity at Work Regulations 1989 if an electrical distribution board on site is found to have a broken door or missing cover?

It must be immediately taken out of service, isolated, and repaired before being re-energised (Correct answer)
It only needs attention at the next scheduled maintenance
Placing a warning cone nearby is sufficient
It can continue to be used if the circuits inside are labelled

Correct answer: It must be immediately taken out of service, isolated, and repaired before being re-energised

Under Regulation 4 of the Electricity at Work Regulations 1989, all electrical systems must be constructed and maintained to prevent danger. A broken door or missing cover exposes live parts and creates a risk of electric shock, water ingress, and accidental contact. The board must be isolated immediately, repaired, and re-inspected before being returned to service.

Question 26: What is the purpose of the SNR (Single Number Rating) on hearing protection?

To show the assumed level of noise reduction in decibels that the hearing protector provides (Correct answer)
To indicate the protector's price category
To indicate the size of the hearing protector
To rate the comfort level of the hearing protector

Correct answer: To show the assumed level of noise reduction in decibels that the hearing protector provides

The SNR is a single figure in decibels that indicates the overall noise reduction provided by a hearing protector under laboratory conditions. In practice, real-world attenuation is typically lower than the SNR, so a real-world factor should be applied when selecting hearing protection.

Question 27: What does the GHS skull and crossbones hazard symbol indicate?

Irritant substance
Flammable substance
Acute toxicity — may be fatal or cause serious harm if inhaled, swallowed, or absorbed through the skin (Correct answer)
Corrosive substance

Correct answer: Acute toxicity — may be fatal or cause serious harm if inhaled, swallowed, or absorbed through the skin

The GHS skull and crossbones symbol (GHS06) indicates acute toxicity. Substances bearing this symbol may be fatal or cause serious harm through inhalation, ingestion, or skin absorption. Workers must follow strict COSHH controls when handling such substances.

Question 28: Under HSE guidance, what weather conditions require additional excavation inspections?

Weather conditions do not affect excavation safety
Heavy rainfall, flooding, frost/thaw cycles, and high winds — any conditions that could affect the stability of the excavation sides or support systems (Correct answer)
Only extreme heat above 30°C
Only snow

Correct answer: Heavy rainfall, flooding, frost/thaw cycles, and high winds — any conditions that could affect the stability of the excavation sides or support systems

Heavy rainfall can saturate soil and reduce its strength; frost/thaw cycles can cause surface layers to crumble; flooding can undermine supports; and high winds can affect working conditions. Under CDM Regulations 2015 Regulation 22, the competent person must reinspect the excavation after any event likely to have affected its stability, including adverse weather.

Question 29: What must be done before any excavation work begins on a construction site under CDM Regulations 2015?

Only a verbal agreement from the site manager is needed
Nothing — excavation can begin as soon as the digger arrives
A permit to dig must be obtained, underground services located using CAT and Genny, and a risk assessment completed (Correct answer)
Excavation can proceed once the weather forecast has been checked

Correct answer: A permit to dig must be obtained, underground services located using CAT and Genny, and a risk assessment completed

CDM Regulations 2015 require that before excavation, all underground services must be identified using utility plans, CAT (Cable Avoidance Tool) and Genny scans, and trial holes where necessary. A permit to dig must be issued, a site-specific risk assessment completed, and a method statement prepared covering support systems, access/egress, and emergency procedures.

Question 30: What reporting requirement applies if a worker suffers a manual handling injury resulting in over 7 days' incapacitation?

No reporting is needed
It must be reported to the HSE under RIDDOR 2013 (Correct answer)
It should be recorded internally only
The worker reports it to their GP only

Correct answer: It must be reported to the HSE under RIDDOR 2013

Under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) 2013, an employer must report to the HSE any injury that results in a worker being incapacitated for more than 7 consecutive days (not counting the day of the accident).

Question 31: What is the primary method for controlling severe bleeding on a construction site?

Wash the wound with antiseptic
Apply direct pressure to the wound (Correct answer)
Raise the limb above the head only
Apply a cold compress

Correct answer: Apply direct pressure to the wound

The primary method for controlling severe bleeding is to apply direct pressure to the wound, ideally using a sterile dressing or clean cloth. A tourniquet should only be used as a last resort when direct pressure has failed to control catastrophic bleeding.

Question 32: Under the Control of Vibration at Work Regulations 2005, what is the daily exposure action value for hand-arm vibration?

1.0 m/s²
2.5 m/s² (Correct answer)
5.0 m/s²
10.0 m/s²

Correct answer: 2.5 m/s²

The daily exposure action value (EAV) for hand-arm vibration is 2.5 m/s² A(8). At this level, employers must introduce a programme of controls to reduce exposure, provide health surveillance, and give information and training to exposed workers.

Question 33: Who is responsible for maintaining PPE in good working condition?

The PPE manufacturer
The worker only
The HSE
The employer must ensure PPE is maintained, and the worker must use and store it properly (Correct answer)

Correct answer: The employer must ensure PPE is maintained, and the worker must use and store it properly

Under the PPE at Work Regulations, employers must ensure PPE is properly maintained, stored, and replaced when necessary. Workers have a duty to use PPE as instructed, report defects, and store it correctly.

Question 34: Under CDM 2015, what is the principal contractor's duty regarding consultation with workers?

No consultation is required
The principal contractor must engage with workers and their representatives on matters affecting their health, safety, and welfare (Correct answer)
Only consult with trade union officials
Only consult with the client

Correct answer: The principal contractor must engage with workers and their representatives on matters affecting their health, safety, and welfare

Under CDM 2015 Regulation 14(d), the principal contractor must consult and engage with workers, including the workforce and their representatives, on matters connected with the project that may affect their health, safety, or welfare. This can be achieved through toolbox talks, safety committees, and worker forums.

Question 35: What type of safety boots are typically required on a UK construction site?

Safety boots with steel or composite toe caps and midsole protection, rated to S3 or equivalent (Correct answer)
Wellington boots
Any waterproof boots
Trainers with ankle support

Correct answer: Safety boots with steel or composite toe caps and midsole protection, rated to S3 or equivalent

Construction sites typically require safety boots rated to at least S3 standard, which includes toe cap protection (200 joules), penetration-resistant midsole, water resistance, and an energy-absorbing heel.

Question 36: What is the maximum recommended length of an extension lead used with 110V equipment on a construction site?

100 metres
50 metres
15 metres (Correct answer)
There is no recommended maximum length

Correct answer: 15 metres

Extension leads for 110V equipment should generally not exceed 15 metres to minimise voltage drop and reduce the risk of damage. Longer leads increase resistance, can cause overheating, and create additional tripping hazards. HSE guidance recommends keeping leads as short as practicable and fully unwound from any drum to prevent overheating.

Question 37: What is the correct procedure before carrying out electrical isolation of equipment on a construction site?

Turn off the main supply to the entire site
Simply unplug the equipment and begin work
Ask a colleague to hold the switch in the off position
Switch off, isolate, lock off, prove dead using a voltage tester, and attach warning notices (Correct answer)

Correct answer: Switch off, isolate, lock off, prove dead using a voltage tester, and attach warning notices

Safe isolation follows a strict sequence: switch off, isolate from all sources, lock off with a personal padlock, prove dead using a GS38-compliant voltage tester (tested before and after on a known live source), and attach warning notices. This procedure is mandated under the Electricity at Work Regulations 1989.

Question 38: What type of excavation support system uses hydraulic rams to hold apart two vertical panels placed against the trench walls?

Open timbering
Hydraulic shoring frames (also known as hydraulic waling frames or speed shores) (Correct answer)
Soil nailing
Sheet piling

Correct answer: Hydraulic shoring frames (also known as hydraulic waling frames or speed shores)

Hydraulic shoring frames use adjustable hydraulic rams between two vertical plates or waling beams to support trench sides. They are quick to install (hence 'speed shores'), adjustable to various trench widths, and can be installed from outside the trench, reducing the risk to operatives. Under CDM Regulations 2015, the competent person specifies the appropriate support system.

Question 39: Which of the nine GHS hazard symbols represents a corrosive substance?

A symbol showing damage to a surface and a hand (Correct answer)
A flame symbol
A gas cylinder symbol
A dead tree and fish symbol

Correct answer: A symbol showing damage to a surface and a hand

The GHS corrosive symbol (GHS05) shows a chemical causing visible damage to a metal surface and to human skin/hand. Corrosive substances on construction sites include strong acids, alkalis, and certain adhesives that can cause severe skin burns and eye damage.

Question 40: What is a Workplace Exposure Limit (WEL) and how does it relate to RPE selection?

A voluntary guideline with no legal force
A legal limit for airborne substance exposure, used to determine the required APF of RPE (Correct answer)
The maximum temperature for work
The maximum number of hours a worker can be exposed

Correct answer: A legal limit for airborne substance exposure, used to determine the required APF of RPE

A Workplace Exposure Limit (WEL) is a legal limit on the concentration of a hazardous substance in workplace air, set under COSHH 2002. The WEL determines the minimum Assigned Protection Factor needed when selecting RPE.

Question 41: Under UK regulations, how often should fire drills be carried out on a construction site?

At regular intervals, typically every 6 months or when there are significant changes to the site layout (Correct answer)
Never — they are not required on construction sites
Daily
Only once at the start of the project

Correct answer: At regular intervals, typically every 6 months or when there are significant changes to the site layout

Fire drills should be carried out at regular intervals to ensure all workers know the evacuation procedure. On construction sites where layouts change frequently, drills may need to be more frequent than in fixed premises.

Question 42: What must a construction site do to comply with the Environmental Protection Act 1990 regarding statutory nuisance from noise?

The site must take all reasonable steps to minimise noise nuisance, including working within permitted hours, using noise barriers and silenced equipment, notifying neighbours, and potentially obtaining a Section 61 prior consent from the local authority (Correct answer)
There is no requirement to control construction noise
Only wearing ear defenders is required
Noise limits only apply to residential construction

Correct answer: The site must take all reasonable steps to minimise noise nuisance, including working within permitted hours, using noise barriers and silenced equipment, notifying neighbours, and potentially obtaining a Section 61 prior consent from the local authority

Under the Environmental Protection Act 1990, noise from construction sites can constitute a statutory nuisance. Local authorities can serve abatement notices under Section 80 requiring noise to be reduced. Best practice includes: obtaining Section 61 prior consent (Control of Pollution Act 1974); working within permitted hours; using silenced plant; erecting acoustic barriers; monitoring noise at sensitive receptors; and maintaining a community liaison programme.

Question 43: Under RIDDOR 2013, which of the following first aid incidents must be reported to the HSE?

A worker taken to hospital after falling from height (Correct answer)
A bruised knee from tripping
A minor cut treated with a plaster
A headache caused by noise exposure

Correct answer: A worker taken to hospital after falling from height

Under RIDDOR 2013, injuries that result in a worker being taken directly to hospital for treatment must be reported to the HSE. Falls from height resulting in hospital treatment are reportable as specified injuries or over-7-day incapacitation injuries.

Question 44: What types of work typically require a permit to work on a construction site?

General labouring and carrying materials
Hot work, confined space entry, electrical work on live systems, and work involving asbestos (Correct answer)
Taking tea breaks
Painting and decorating

Correct answer: Hot work, confined space entry, electrical work on live systems, and work involving asbestos

Permits to work are typically required for high-risk activities including hot work (welding, burning, grinding), confined space entry, work on or near live electrical systems, excavation near buried services, work involving asbestos, work on pressurised systems, and any task where a specific safe system of work must be followed.

Question 45: Why is smoking particularly dangerous for workers who have been exposed to asbestos?

Smoking actually protects against asbestos fibres
Smoking only slightly increases the risk
Smoking combined with asbestos exposure increases the risk of lung cancer by up to 50 times compared to someone who neither smokes nor is exposed to asbestos — the two risk factors are synergistic (Correct answer)
Smoking has no effect on asbestos-related health risks

Correct answer: Smoking combined with asbestos exposure increases the risk of lung cancer by up to 50 times compared to someone who neither smokes nor is exposed to asbestos — the two risk factors are synergistic

Smoking and asbestos exposure have a synergistic (multiplicative) effect on lung cancer risk. While asbestos exposure alone increases lung cancer risk by approximately 5 times and smoking alone by approximately 10 times, the combined exposure increases the risk by up to 50 times. This is why health surveillance programmes for asbestos workers strongly advise smoking cessation.

Question 46: How often must LEV systems be examined and tested under COSHH Regulation 9?

Every 6 months
Every 2 years
At least every 14 months (Correct answer)
Only when a fault is suspected

Correct answer: At least every 14 months

Under COSHH Regulation 9, LEV equipment must be thoroughly examined and tested at least every 14 months (or more frequently for certain processes). Records of examinations must be kept for at least 5 years.

Question 47: What is the purpose of a spill kit on a construction site and what should it contain?

A spill kit is a first aid kit for chemical burns
A spill kit is only needed at petrol stations
A spill kit is designed to contain and clean up accidental spills of oil, fuel, chemicals, or other pollutants before they reach drains or watercourses — it should contain absorbent granules, pads, booms, disposal bags, and PPE (Correct answer)
A spill kit is a tool for cleaning concrete spillages

Correct answer: A spill kit is designed to contain and clean up accidental spills of oil, fuel, chemicals, or other pollutants before they reach drains or watercourses — it should contain absorbent granules, pads, booms, disposal bags, and PPE

Spill kits are an essential pollution prevention measure on construction sites. They must be readily available wherever oil, fuel, or chemicals are stored or used. A typical kit contains absorbent granules, absorbent pads and rolls, containment booms (for watercourses), drain mats or covers, heavy-duty disposal bags, and PPE (gloves, goggles). All operatives should be trained in their use. This supports compliance with the Environmental Permitting Regulations 2016.

Question 48: What obligation does an employer have regarding the provision of hearing protection at the upper exposure action value of 85 dB(A)?

Hearing protection is optional
Hearing protection only needs to be available on request
Hearing protection is only required for workers over 50
The employer must ensure hearing protection is provided AND worn by all exposed workers (Correct answer)

Correct answer: The employer must ensure hearing protection is provided AND worn by all exposed workers

At or above the upper exposure action value of 85 dB(A), employers must ensure that suitable hearing protection is not only provided but actually worn by all exposed workers. This is a mandatory requirement, unlike at the lower action value where hearing protection only needs to be made available.

Question 49: What user checks should be carried out on a portable electrical tool before each use on a construction site?

No checks are needed if the tool has a current PAT sticker
Checks are only required weekly, not before each use
Visual inspection of the plug, cable, and casing for damage, and checking the PAT test date is current (Correct answer)
Only check that the on/off switch works

Correct answer: Visual inspection of the plug, cable, and casing for damage, and checking the PAT test date is current

Before each use, operatives must visually inspect the plug (no cracks, pins straight), cable (no cuts, kinks, or exposed conductors), casing (no damage), and confirm the PAT test label is current. This is required under the Electricity at Work Regulations 1989 and PUWER 1998. A current PAT sticker does not guarantee the tool has not been damaged since the last test.

Question 50: What health risk is directly associated with poorly maintained sanitation facilities on a construction site?

Increased risk of electrical faults in welfare areas
Increased risk of illness and infection spreading among workers (Correct answer)
Increased risk of fire from combustible materials

Question 51: What is the significance of the IP rating 'IP65' on a construction site distribution board?

IP65 is a fire resistance rating
It means the enclosure is dust-tight (6) and protected against water jets (5) from any direction, making it suitable for harsh outdoor construction environments (Correct answer)
It indicates the board can only be used indoors
It refers to the maximum amperage the board can handle

Correct answer: It means the enclosure is dust-tight (6) and protected against water jets (5) from any direction, making it suitable for harsh outdoor construction environments

The IP (Ingress Protection) rating system defined in BS EN 60529 uses two digits: the first (6) indicates complete protection against dust ingress, and the second (5) indicates protection against water jets from any direction. IP65 is suitable for outdoor construction site use where boards are exposed to dust, rain, and wash-down. BS 7671 requires equipment to be suitable for its environment.
