The area can accumulate up to 100 gallons of non-acute hazardous waste.
A formal contingency plan must be posted in the satellite accumulation area.
Weekly inspections of the containers must be documented.

Correct answer: Waste containers must be located at or near the point of generation and under the control of the operator.

RCRA regulations for satellite accumulation areas (SAAs) at 40 CFR 262.15 state that containers must be at or near the point of generation where the waste initially accumulates and must be under the control of the operator of the process generating the waste. While weekly inspections and contingency plans are required for central accumulation areas, they are not specific requirements for SAAs. The accumulation limit for non-acute hazardous waste in an SAA is 55 gallons.

Question 62: Which of the following is NOT one of the 14 elements of OSHA's Process Safety Management standard?

Compliance Audits
Hot Work Permits
Environmental Impact Assessment (Correct answer)
Employee Participation

Correct answer: Environmental Impact Assessment

Environmental Impact Assessment is an NEPA requirement for federal actions, not an element of OSHA's PSM standard, which focuses on preventing catastrophic chemical releases at fixed facilities.

Question 63: Under OSHA PSM, a Pre-Startup Safety Review (PSSR) is required before introducing a highly hazardous chemical to a process when:

A new facility is started up or a significant modification has been made to an existing process (Correct answer)
An OSHA inspection is scheduled
Any employee requests one
The chemical inventory exceeds 50% of the threshold quantity

Correct answer: A new facility is started up or a significant modification has been made to an existing process

PSSR is required for new facilities and when modifications are significant enough to require a change in the process safety information, ensuring all elements are in place before startup.

Question 64: Which organization publishes Threshold Limit Values (TLVs) used as guidelines for airborne chemical exposure in the workplace?

National Institute for Occupational Safety and Health (NIOSH)
American Conference of Governmental Industrial Hygienists (ACGIH) (Correct answer)
American Industrial Hygiene Association (AIHA)

Question 67: Under PSM, how long must employers retain the five most recent compliance audit reports?

5 years
3 years
10 years
Until the next audit is completed (Correct answer)

Correct answer: Until the next audit is completed

29 CFR 1910.119(o)(3) requires employers to retain the two most recent compliance audit reports, not a set number of years — they must be kept until replaced by newer audits.

Question 68: An 8-hour time-weighted average (TWA) exposure measurement is used to compare against which OSHA exposure limit type?

Ceiling Limit (C)
Immediately Dangerous to Life or Health (IDLH)
Permissible Exposure Limit (PEL) (Correct answer)
Short-Term Exposure Limit (STEL)

Correct answer: Permissible Exposure Limit (PEL)

OSHA PELs are 8-hour TWA values; STELs apply to 15-minute exposures and ceiling limits must never be exceeded at any instant.

Question 69: What is the primary purpose of a Hearing Conservation Program baseline audiogram?

To establish a reference hearing level against which future tests are compared to detect hearing loss (Correct answer)
To immediately determine if a worker requires hearing aids
To comply with workers' compensation insurance requirements
To measure noise levels in the facility

Correct answer: To establish a reference hearing level against which future tests are compared to detect hearing loss

The baseline audiogram establishes each worker's initial hearing threshold, enabling comparison with annual audiograms to detect standard threshold shifts (STS) early.

Hazardous air pollutant emissions
Stratospheric ozone depletion
Acid rain (Correct answer)
Urban smog

Correct answer: Acid rain

A key feature of the 1990 Clean Air Act Amendments was the establishment of the Acid Rain Program under Title IV. This program set a cap on total sulfur dioxide (SO2) emissions from power plants and created a market-based cap-and-trade system of allowances to reduce SO2 and nitrogen oxide (NOx) emissions, the primary precursors of acid rain.

Question 75: A manufacturing facility plans to replace an old piece of machinery with a new, faster model that uses a different chemical solvent. According to formal SMS principles, what specific process is essential to complete before this change is implemented?

Incident Investigation
Job Hazard Analysis (JHA)
Annual Program Review
Management of Change (MOC) (Correct answer)

Correct answer: Management of Change (MOC)

A Management of Change (MOC) is a systematic process for evaluating the safety, health, and environmental risks associated with any changes to processes, equipment, chemicals, or procedures before the change is made. This proactive evaluation is critical to ensure that new hazards are not introduced. A JHA might be part of the MOC, but MOC is the overarching required process.

Question 76: What is a key element of effective hazard control?

Delaying corrective actions.
Avoiding hazard communication.
Using multiple controls and monitoring (Correct answer)
Ignoring hazard reports.

Correct answer: Using multiple controls and monitoring

Effective hazard control involves implementing a hierarchy of controls, which often means using a combination of engineering, administrative, and personal protective equipment (PPE) measures. Simply applying one control may not be sufficient. Continuous monitoring is also essential to ensure these controls remain effective over time and to identify any new or evolving hazards.

Question 77: What is the Clean Air Act designed to regulate?

365 days
120 days
180 days (Correct answer)
90 days

Correct answer: 180 days

Federal regulations under the Clean Water Act specify that to continue discharging beyond the 5-year maximum term of an NPDES permit, the permittee must submit a complete renewal application at least 180 days before the existing permit expires. This allows the permitting authority adequate time to review the application and issue a new permit.

Question 90: A chemical is classified as a 'skin sensitizer' under GHS. What does this mean for exposure assessment?

The chemical is primarily an inhalation hazard
The chemical has an established skin PEL that must be monitored
The chemical causes immediate burns on contact
Dermal exposure can cause an allergic reaction upon re-exposure even at low concentrations (Correct answer)

Correct answer: Dermal exposure can cause an allergic reaction upon re-exposure even at low concentrations

Skin sensitizers cause allergic contact dermatitis; once sensitized, a worker can react severely to even trace exposures, making skin contact prevention critical.

Question 91: What are environmental compliance audits?

Financial inspections.
Building safety checks.
Assessments of environmental compliance (Correct answer)
Employee evaluations.

Correct answer: Assessments of environmental compliance

Environmental compliance audits are systematic, documented assessments designed to evaluate an organization's adherence to environmental laws, regulations, permits, and internal policies.

When a chemical is exported overseas
When any new chemical is synthesized
When annual production exceeds 10,000 lbs
When a chemical is used in a manner designated as a 'significant new use' by EPA rulemaking (Correct answer)

Correct answer: When a chemical is used in a manner designated as a 'significant new use' by EPA rulemaking

A SNUR requires submission of a Significant New Use Notice (SNUN) before any manufacturer or processor begins a use that EPA has designated as a significant new use.

Question 97: What is the role of personal protective equipment (PPE)?

To protect workers when hazards remain (Correct answer)
To eliminate hazards.
To increase risks.
To replace training.

Correct answer: To protect workers when hazards remain

The role of Personal Protective Equipment (PPE) is to protect workers when hazards cannot be entirely eliminated or controlled through engineering or administrative measures. PPE acts as a last line of defense, minimizing exposure to risks by providing a barrier between the worker and the hazard, such as safety glasses, gloves, or respirators.

Question 98: How can safety be integrated into daily operations?

By ignoring safety.
By integrating safety into daily tasks (Correct answer)
By skipping equipment maintenance.
By avoiding safety meetings.

Correct answer: By integrating safety into daily tasks
