The Responsible Person in Charge shall determine the need for the use of an explosion meter. In locations where flammable gases or vapors potentially could be present, a Roving Firewatch shall be utilized. In these situations, the Roving Firewatch shall be sufficiently trained to use and provided with an explosion meter by the Operation. (The roving firewatch is in addition to the original firewatch) If the explosion meter reading indicates a percent of the lower explosive limit, the hot work shall be stopped and the problem corrected before hot work can restart.
The fire watch shall continually survey the work area for combustible material
More than one fire watch could be needed depending on potential, the impact on other areas (such as floors below the hot work activity) and the complexity
If a potential for a spill in an adjacent area could create a hazard, a roving monitor with an explosion meter shall be assigned to patrol the area with instructions to immediately stop the hot work if flammables are detected. The roving monitor cannot be the fire watch. If the roving monitor is contract, he/she must be fire watch trained, as per this policy
The fire watch shall complete the appropriate sections of Hot Work Permit (i.e. Name, Year Trained, and location of nearest pull alarm box/telephone) before beginning the hot work.
A fire watch shall be maintained for at least a half-hour after completion of welding or cutting operations to detect and extinguish possible smoldering fires
Upon completion of the hot work, the fire watch shall inspect the site thoroughly to insure that no smoldering embers remain and complete the hot work permit by signing the permit and listing the time he/she leaves the area under the Post Hot Work section of the permit
A fire watch could act as a confined space attendant if, the fire watch is trained in both functions AND the hot work is inside the confined space
After successful completion of the Fire Watch training, the individual shall receive a valid authorization card. This card shall be made available to the RPC and to any auditor to verify the fire watch has received valid training.
•Has the last material in the equipment being worked on been specified along with the cleaning method used. If the equipment/line last contained a combustible or flammable material, has it been completely purged with an inert (non-oxygen containing) material (e.g. nitrogen gas)? If residues may remain in the equipment/line or it has not been completely cleaned, has the permit made note of hazards of material still in the system and how to mitigate the hazards.
•Has atmospheric monitoring been conducted of the work area if required. for consideration of the need for oxygen monitoring to monitor for low oxygen content in the atmosphere in the case of purging with inert gas.
