Before considering any roof project complete, walk the roof and check laps for any signs of unbonded areas (a trowel can be used for this purpose). Check flashing details to be sure they are secure. Leave roof and premises clean and free of any roofing debris (daily). Be sure all vent caps are snug and drain screens securely in place.
As stated in the warning on page 18, use of propane torches and hot as- phalt requires thorough knowledge and skill in all aspects of safety with re- spect to their use and handling. CertainTeed recommends that professional applicators receive the CERTA torch safety training as offered by the MRCA or NRCA (see inside cover) and participate in all asphalt heating and handling safety training available through their local roofing associations, ARMA and NFPA (see inside cover), local fire departments, OSHA and the NRCA, among others.
Under no circumstances should Flintlastic modified bitumen roofing application be attempted by “do-it-yourselfers” or any persons other than professional, trained roofers. It is the roofing contractor’s sole responsibility to be certain all crew members are appropriately trained in safe and proper use of propane torching and hot asphalt equipment and procedures.
The following safety tips are a general reference only and are in no way all-inclusive.
Job Watch When the torch application method is used, it is important to remember that carelessness resulting in heat entering a crevice may cause concealed smoldering. A supervisor trained in fire safety should remain on the jobsite a minimum of 4 hours after cessation of torching to check for any signs of smoke, smoldering or fire. The safety check should utilize infra-red thermometers and should include a thorough interior check of the attic, crawl spaces and return air ducts in addition to the roof area where torches have been utilized. Prior to leaving the jobsite the contractor must be cer- tain that all chance of fire, including smoldering fire, has been eliminated.
Proper clothing, including work boots, long pants, long sleeved shirts and gloves, must be worn. It is the contractor’s responsibility to require employees to wear proper attire.
Workmen, other than the torch operator, should be not closer than 3 feet to the torch flame.
