Installation procedures for U.S. Intec torch applied modified bitumen membranes must be followed. Particular caution must be taken when working around combustible materials, such as gas lines for HVAC units and in the presence of solvent-based products. All potential combustible materials used in the building and design considerations that increase the risk of fire mst be identified prior to application. Torch application equpment must be designed for that specific purpose, must be in proper working order and the manufacturer's safety and operating instructions for the torch system must be followed. Keep the torch flame moving.
Adequate ventilation is required.
Potential oxygen depletiion when working in confined spaces must also be taken into consideration. Since fires can result hours after completion of work, periodic inspection thereafter must be made. The watches shall never be less than one hour and may need to be longer. Time and nature of the watches will vary depending on the weather, building roof design and composition, and penetration types and design. Infrared scanning equipment must be used in the fire watch.
