When using an oxy-acetylene torch on a construction site, which cylinder must always be stored and transported in an upright position?
Answer: Both oxygen and acetylene cylinders
Both oxygen and acetylene cylinders must always be stored and transported in the upright position to prevent accidents.
On a construction site, what is the correct way to check for a gas leak in a cylinder hose connection?
Answer: Apply soapy water solution and observe for bubbles
Soapy water solution applied to connections is the safe method to detect gas leaks — bubbles indicate a leak.
A fire guard on a construction site observes that torch work is being performed within 5 feet of a polyurethane foam insulation panel. What is the correct response?
Answer: Stop work immediately — polyurethane foam is highly flammable and requires greater clearance or removal
Polyurethane foam is highly flammable and releases toxic gases when ignited; hot work must stop until adequate clearance or protection is established.
Which of the following is the fire guard's responsibility BEFORE torch operations begin at a construction site each day?
Answer: Conduct a pre-work inspection of the hot work area for hazards
The fire guard must conduct a pre-work hazard inspection of the hot work area before operations begin each day.
Acetylene gas becomes unstable and potentially explosive when stored or used at pressures above which threshold?
Answer: 15 PSI
Acetylene is unstable and can detonate when used or stored at pressures above 15 PSI.
On a construction site, what must a fire guard do if the hot work zone is adjacent to a fire-rated wall assembly that has open penetrations?
Answer: Ensure all penetrations are temporarily sealed before torch operations begin
Open penetrations in fire-rated assemblies allow fire and smoke to spread; they must be temporarily sealed before hot work begins nearby.
Which of the following actions by the torch operator should the fire guard immediately correct on a construction site?
Answer: Leaving the torch lit and unattended while retrieving materials 20 feet away
A lit torch must never be left unattended — this is a serious fire hazard and violates hot work safety rules.
