Only those rated as quantified in the production safety education and training can take up their posts. The key person(s) in charge of the enterprise and the safety production management personnel shall pass the examination of safety production knowledge and management ability. Special operation personnel shall receive special safety production training. 4.2.2 Following the principle of minimizing people (even to zero) in hazardous jobs, during normal production, the number of personnel entering the same chlorine production installation (plant building) and storage site at the same time shall not exceed 3. In other cases, the number of on-site workers shall be controlled to realize risk monitoring and early warning of personnel gathering based on the personnel positioning system. 4.2.3 The number of operators in the liquid chlorine filling place shall not exceed 2. 4.2.4 To handle abnormal conditions, corresponding measures shall be formulated by following the principles of timely retreating to a safe state, minimizing on-site disposal personnel, comprehensively identifying and analyzing and properly handling risks, effectively preventing accidental release of energy, and conduct unified command based on overall consideration. The number of on-site handling personnel shall not exceed 6. 4.2.5 Fire operations shall not be carried out on the outer walls of chlorine equipment and pipelines not emptied. If fire operations near chlorine equipment and pipelines are necessary, spark prevention and heat insulation measures shall be taken to prevent the temperature of the outer wall of chlorine equipment and pipelines made of carbon steel from exceeding 121°C. 4.2.6 If liquid chlorine transportation is stopped, the pipeline shall not be closed to prevent itself from being full of liquid and closed. When the pressure in the liquid chlorine pipeline is abnormal, safe relief or evacuation measures shall be taken. In case of halt in production or leakage, measures, such as evacuation or nitrogen and dry air replacement, shall be taken, and the pipeline shall be isolated from the liquid chlorine system. 4.2.7 Workers in places with chlorine shall wear portable chlorine alarms and use personal protective equipment meeting the requirements of GB 39800.2. 4.2.8 The material safety data sheet (MSDS) of chlorine shall meet the requirements of GB/T 16483 and GB 17519.
