Class A factory buildings are not equipped with control rooms
Thread Content
For a current project, the process equipment in Class A workshops is required not to be located in the control room. Only explosion-proof PLC cabinets are installed on-site, and all operations are also carried out there. Is this acceptable in accordance with the current regulatory requirements? Are there any regulations that explicitly prohibit the absence of a control room? Or are there regulations stating that it is not allowed for all points of this device to be connected to a PLC cabinet installed on-site?
In accordance with regulations and standards such as the Regulations on the Safety Management of Hazardous Chemicals and the Safety Specifications for Hazardous Chemicals, control rooms should generally be established for Class A plant installations to ensure the safety of operators and the reliable operation of the installations. However, if a safety assessment is conducted and the specified conditions are met, the need for a control room can be reduced or eliminated. The specific situation needs to be evaluated and determined based on the process equipment and production environment. The explosion-proof PLC cabinets installed on-site must meet the corresponding explosion-proof requirements and electrical safety standards. Therefore, in practical operations, safety assessments and reasonable design should be carried out in accordance with relevant regulations, standards, and technical requirements to ensure the safe and stable operation of the device. .
Neither of these specifications mentions it; are there any requirements regarding the use of hazardous chemicals in the case of active pharmaceutical ingredients, rather than during the production process?
Notice from the State Council’s Work Safety Committee on the issuance of the \"Three-Year Action Plan for Special Rectification of Work Safety Nationwide\" (Safety Committee [2020] No. 3); Annex 3: Implementation plan for the three-year action plan for special rectification of safety issues related to hazardous chemicals – the requirements outlined therein. In principle, the control rooms and shift change rooms for production units with Class A or B fire hazards shall not be located within the facility area. If installation is indeed necessary, an explosion-proof design must be implemented.
