What fire extinguishers cannot be equipped in the clean workshop, what fire fighting facilities should the clean workshop be equipped with?

1. The clean workshop cannot be equipped with any fire extinguishers Since it is a clean workshop, it must be pollution-free for the environment and equipment. Therefore, dry powder fire extinguishers and foam fire extinguishers are not suitable for clean workshops. Because dry powder fire extinguishers release a lot of dust during operation, the foam in foam fire extinguishers may cause corrosion of some clean room pharma machinery. When we use a fire extinguisher, we do not have full control over the range of the fire extinguisher. Dust falls on various workshop equipment, some of which are relatively small and invisible to the naked eye. After the dry powder fire extinguisher is used, there will be a large amount of dust residue, which will pollute or corrode some equipment. Therefore, gas fire extinguishers are generally used in clean rooms. Moreover, the gas fire extinguisher is not very expensive, and the retirement life is longer than that of the dry powder... Carbon dioxide gas fire extinguishers can not only achieve the fire extinguishing effect, but also ensure that the workshop equipment is not polluted. And the price of gas fire extinguisher is also very reasonable, and the service life is relatively long. As such, it is ideal for pharma clean room backup fire extinguishers. 2. What fire-fighting facilities should be equipped in the clean workshop 1. Automatic sprinkler system The automatic sprinkler system has become the first facility of the clean workshop fire-extinguishing system. Fixed fire extinguishing facilities must be installed in rooms with many valuable production equipment and precision instruments in the clean workshop. In addition to water fire extinguishing system, carbon dioxide gas fire extinguishing system, IG541 mixed gas fire extinguishing system, trifluoromethane automatic fire extinguishing system and heptafluoropropane gas fire extinguishing system can also be installed. 2. Automatic fire alarm system The clean workshop must be equipped with automatic fire alarm system and fire linkage control in the production area, technical mezzanine, computer room, station room and other areas, and the corridor must be equipped with manual fire alarm buttons. 3. Carbon dioxide fire extinguishers Dry powder fire extinguishers and water-based fire extinguishers are not allowed in clean workshops. Carbon dioxide fire extinguishers are best used in clean workshops, because carbon dioxide fire extinguishers will not leave traces, will not pollute equipment and anti-corrosion items, will not be cleaned twice after use, and will not pollute the air environment of clean workshops. Therefore, carbon dioxide fire extinguishers are used in clean rooms. has been widely used. 4. Emergency lighting and evacuation signs The clean workshop must be equipped with emergency lights and evacuation signs, so that internal personnel can carry out emergency evacuation when they encounter a fire station. 5. Fire hydrants Fire hydrants should be installed in the clean pharmaceutical cleanroom, and indoor fire hydrants can only be installed on the production floor and the upper and lower technical interlayers (except for inaccessible technical interlayers). The water consumption of the fire hydrant in the clean workshop is not less than 10 liters per second, the number of water guns used at the same time is not less than 2, the full water column of the water gun is not less than 10 meters, and the water output of each water gun is not less than 5 liters per second. A sprinkler system must be installed in a clean room, even if you don't need it. Don't be afraid that after turning on the sprinkler system, the valuable equipment and instruments in the clean room will be damaged, because if the fire is not put out in time, the loss will be even greater. 3. Safety measures for gas pipelines The trunk of the gas pipelines in the clean workshop should be laid in the upper and lower technical interlayers or technical channels. Should be installed on top of them when they are tangled in water and wires. Pipes not related to the clean workshop shall not pass through. Natural gas pipelines with different media should be clearly marked. All kinds of gas cylinder storage warehouses should be centrally set up outside the clean workshop. When the gas consumption on the day does not exceed 1 bottle, gas bottles can be installed in the clean workshop, but measures must be taken to prevent dust accumulation and facilitate cleaning. (1) The flammable gas alarm device and the accident exhaust device are highly flammable and explosive, and are likely to cause a combustion and explosion accident, and when a safety accident occurs, it will spread widely and be harmful, resulting in serious property losses. The following A combustible gas alarm device and an accident exhaust device should be installed at the part, and the alarm device should be interlocked with the corresponding accident exhaust fan: a. The gas inlet chamber for Class A fire hazard production. b. In the pipe gallery, the upper and lower technical interlayers or technical interlayers are prone to accumulation of combustible gas pipes. c. Where combustible gas is used in the clean room. (2) Pipeline safety technical measures a. Combustible gas pipelines shall be provided with the following safety technical measures: flame arresters shall be provided for branch pipes and release pipes connected to gas-using equipment; lightning protection facilities shall be provided for release pipes leading to the outdoors; A grounding facility to remove static electricity. b. The following safety technical measures shall be provided for oxygen pipelines: Pipelines, valves, and accessories shall be subjected to severe degreasing treatment; Grounding facilities to conduct static electricity shall be provided.
