**
1. All flammable material in the work site area must be removed or protected. The work site area is considered a circle whose radius is the distance hot sparks can travel, plus ten feet. Often the work site area can be reduced by asbestos trap or wind screens.
*-
a. Ordinary combustibles, such as trash, wood or paper will be removed.
b. Combustible liquids on the ground, or in open containers, will be removed.
2. Before hot work begins, the job area will be surveyed for VCM or other combustible vapor and all such sources eliminated.
3. All sewer drains within the work site area will be covered or water flooded. They will be uncovered right after the job is completed.
4. If hot work is to be done in an enclosed system, such as , a vessel, tank, or piping, the enclosed space must be gas
freed and steps taken to be sure it remains gas freed.
a. The space must be isolated from all connecting vessels or piping by blinds or physical disconnection. (1) The blinds must be installed on the flange located closest to the enclosed space. (2) The blinds must have the same pressure rating as the flange. (3) Operations will see that all blinds are removed before start-up.
b. The space will be water washed and/or steamed until the combustible gas is removed (zero, as measured by com bustible gas analyzer). (1) Check for anything that could trap or retain combustible material, such as: scale, sludge, lining, double walls, structural members or piping, or pools. (2) Steam hoses must be bonded or grounded by: (a) Direct connection of the nozzle to metal piping. (b) Bonding wire attached between the nozzle and ground. (3) When using a steam hose to purge or clean an open vessel, any internal metalic object that is elec trically insulated and subjected to steam infringe ment or condensation, must be: removed, bonded, or grounded. (4) If the space is to be inerted or flooded, the job will be considered a procedure deviation and there fore the Operating Department Head and Safety Director approvals are required. (5) A Fire Guard is required whenever hot work is done in an operating process area. The Fire Guard duties are:
