A construction crew using a propane heater on the 5th floor reports headaches and dizziness. What do these symptoms most likely indicate?
Answer: Carbon monoxide poisoning requiring immediate evacuation
Headaches and dizziness in workers near fuel-burning equipment are classic early CO poisoning symptoms requiring immediate evacuation.
What minimum ventilation rate is required when operating fuel-burning heating equipment in an enclosed construction space?
Answer: At least one complete air change per hour, or more as required by CO testing
At minimum, one complete air change per hour is required, and CO monitoring should verify that levels remain below OSHA PEL with this ventilation rate.
What should an F-03 fire guard do at the end of each shift regarding temporary heating equipment?
Answer: Log the equipment status, confirm safe operating condition, and brief the incoming fire guard
At shift change, the outgoing F-03 must document equipment status and fully brief the incoming fire guard on all temporary heating hazards and conditions.
During freezing weather, a general contractor requests that propane heaters be placed inside partially enclosed scaffolding to protect newly poured concrete. What should the F-03 fire guard assess?
Answer: Assess ventilation adequacy, CO risk, clearance from combustibles, and ensure fire watch coverage
The F-03 must evaluate the specific fire and CO hazards created by this heating arrangement and ensure all safety requirements are met before allowing it to proceed.
What is the correct response when a temporary heater's automatic pilot light goes out and the heater shuts off on a construction site?
Answer: Wait 5 minutes for gas to dissipate, ventilate the area, then follow manufacturer restart procedures
After a pilot outage, waiting at least 5 minutes allows accumulated unburned gas to dissipate before attempting a restart.
What records must an F-03 fire guard maintain regarding temporary heating equipment on a construction site?
Answer: A fire watch log including equipment inspections, CO readings, incidents, and shift changes
F-03 fire guards must maintain a fire watch log documenting equipment inspections, CO monitoring results, any incidents, and shift changes.
