Which type of temporary heater is safest for use in poorly ventilated enclosed construction spaces?
Answer: Electric resistance heater
Electric heaters produce no combustion products, eliminating CO risk in enclosed spaces where ventilation is limited.
What does a CO detector alarm at 35 ppm require on a construction site?
Answer: Immediate ventilation increase and investigation of the CO source
35 ppm triggers investigation and ventilation improvement — it is approaching OSHA action levels and indicates incomplete combustion that needs correction.
What is the minimum required setback for fuel storage tanks from temporary heating equipment?
Answer: 25 feet
Propane or fuel tanks must be stored at least 25 feet from any temporary heating equipment to prevent exposure to radiant heat and potential BLEVE.
How frequently must temporary heating equipment be inspected on a construction site?
Answer: Before each use and at the beginning of each work shift
Temporary heating equipment must be inspected before each use and at the start of each shift to verify safe operating conditions.
What does the orange-yellow color of a flame from a propane heater indicate?
Answer: Incomplete combustion producing high levels of carbon monoxide
Orange-yellow flames indicate incomplete combustion — insufficient oxygen or excess fuel — which produces dangerous levels of carbon monoxide.
What permit is required from FDNY to operate certain temporary heating equipment on NYC construction sites?
Answer: A Temporary Heating Equipment Permit from FDNY Bureau of Fire Prevention
FDNY requires a Temporary Heating Equipment Permit for heating equipment used on construction sites to verify safe installation and operation.
