If welding is to be done on a metal wall, partition, ceiling, or roof, precautions shall be taken to prevent ignition of combustibles on the other side, due to conduction or radiation, preferably by relocating combustibles. Where combustibles are not relocated, a fire watch on the opposite side from the work shall be provided. Welding shall not be attempted on a metal partition, wall, ceiling, or roof having a combustible covering, nor on walls or partitions of combustible sandwich-type panel construction. Cutting or welding on pipes or other metal in contact with combustible walls, partitions, ceilings, or roofs shall not be undertaken if the work is close enough to cause ignition by conduction. Fully charged and operable fire extinguishers, appropriate for the type of possible fire, shall be available at the work area.
Contractors are responsible to furnish appropriate fire extinguishers during the project.
Where welding or cutting is done in close proximity to a sprinkler head, a wet rag shall be laid over the head and then removed at the conclusion of the welding or cutting operation. Nearby personnel shall be suitably protected against heat, sparks, slag, etc. Detectors cannot be covered with gloves, tape, plastic, etc. without prior approval of UT Houston Physical Safety. Adequate ventilation depends upon the following factors. Volume and configuration of space in which operations occur.
