A.188.8.131.52.1 The steps and safeguards necessary to prevent injury or death to personnel in areas whose atmospheres will be made hazardous by the discharge or thermal decomposition of clean agents can include the following:
(1)Provision of adequate aisleways and routes of exit and procedures to keep them clear at all times.
(2)Provision of emergency lighting and directional signs as necessary to ensure quick, safe evacuation.
(3)Provision of alarms within such areas that will operate immediately upon detection of the fire.
(4)Provision of only outward-swinging, self-closing doors at exits from hazardous areas and, where such doors are latched, provision of panic hardware.
(5)Provision of continuous alarms at entrances to such areas until the atmosphere has been restored to normal.
(6)Provision of warning and instruction signs at entrances to and inside such areas. These signs should inform persons in or entering the protected area that a clean agent system is installed and should contain additional instructions pertinent to the conditions of the hazard.
(7)Provision for the prompt discovery and rescue of persons rendered unconscious in such areas. This should be accomplished by having such areas searched immediately by trained personnel equipped with proper breathing equipment. Self-contained breathing equipment and personnel trained in its use and in rescue practices, including artificial respiration, should be readily available.
(8)Provision of instruction and drills for all personnel within or in the vicinity of such areas, including maintenance or construction people who could be brought into the area, to ensure their correct action when a clean agent system operates.
(9)Provision of means for prompt ventilation of such areas. Forced ventilation will often be necessary. Care should be taken to readily dissipate hazardous atmospheres and not merely move them to another location.
(10)Prohibition against smoking by persons until the atmosphere has been determined to be free of the clean agent.
(11)Provision of such other steps and safeguards that a careful study of each particular situation indicates is necessary to prevent injury or death
