  • It is the contractor’s responsibility to observe all fire prevention policies and practices during the installation of the roof system.

  • It is the contractor’s responsibility to train, instruct and warn employees on the use and handling of propane torching equipment.

  • Extra caution must be used when torching near exposed edges of insulation to prevent flame from coming into contact with any flammable material. Contact for any length of time with lead or other materials affected by heat must be avoided.

  • Never use the equipment in an enclosed area.

  • Refer to NFPA S8 “Standard for the Storage and Handling of Liquified Petroleum Gas” and appropriate publications of the National Propane Gas Association (1150 17th St. NW, Ste. 310, Washington, DC 20036-4623 Ph. 202-466-7200) and the National Fire Protection Association (1 Batterymarch Park, Quincy, MA 02169-7471 Ph. 617-770-3000).

Fire Department Regulations

  • Written notice should be given to the local fire department and any necessary permits must be acquired.

  • The required number of fire extinguishers shall be on the roof at all times.

  • Portable smoke detectors should be installed in attics as required by the local fire department.

  • All supervisors and crew members on the jobsite shall have fire safety training. The crew supervisor or foreman must remain on the jobsite at least 4 hours after cessation of torching, and shall check the complete roof and attic area for any signs of smoke or smoldering.

  • No flammable liquids shall be stored or used on the roof (excluding LPG in approved containers). Any LPG not in use shall be stored on the ground.

Tools and Equipment

  • Be certain that all torching equipment is in good working order.

  • Be certain cylinder valves are clean.

  • Use an adjustable pilot with a complete shut-off valve.

  • Use a flint or electronic ignitor to light the torch. Matches or disposable lighters are unsafe and not acceptable.

  • Do not use any equipment without an operating pressure gauge.

  • Do not operate any pressure gauge beyond the top of its scale, near excessive heat (above 150°F) or where there is excessive vibration.

  • Use a torch stand to direct the torch flame upward when the torch is briefly set down. Shut off completely when not in use.
