With the development of the national economy, social progress and the improvement of people's living standards, clean rooms have been widely used in electronics, biopharmaceuticals, precision instrument manufacturing and other industries, due to the huge advantages of clean rooms in temperature, relative humidity and cleanliness, its importance is also increasingly recognized and accepted by people. This paper discusses some opinions on how to do a good job in fireproof design of clean room.
First, the basic characteristics of clean rooms
Clean room refers to the workshop that has special purification requirements for the building in the production process.
Its basic characteristics are: 1, mostly reinforced concrete structure, the workshop is divided into several small rooms; 2, often in a closed state, less Windows and fewer doors; 3, the equipment in the plant is expensive, afraid of high temperature, avoid water; 4. Fewer staff in the factory, which is not conducive to discovering the fire and dealing with the initial fire; 5, the internal structure is complex, the channel twists and turns.
Second, the fire characteristics of clean rooms
1, smoke heat accumulation, spread in many ways
The clean room is generally closed, with few doors and Windows, and in the event of a fire, the smoke heat is not easy to disperse out, resulting in smoke detention and heat increase. Coupled with the collusion of ventilation pipes, electrical line bushings and technical interlayers in the plant, it is easy to cause the smoke heat to flow to other rooms and spread rapidly.
2, personnel escape difficulties
Due to the requirements of the process, the internal separation of the clean room is complex, the channel is tortuous and narrow, the safety exit is less, the depth and distance are long, and the fire is easy to lose its direction after the fire, coupled with fewer staff, the initial fire is difficult to find in time, and it is difficult to get away when the fireworks attack.
3, smoke toxicity
Some polymer synthetic materials are used in the interior decoration, which will produce a lot of smoke and emit gas in the event of combustion, which will bring great threats to personnel escape and fire fighting personnel.
4. Big loss
There are often a lot of very sophisticated and valuable equipment in the clean room, and the construction investment is large, and the economic loss is huge in the event of a fire.
In addition, some clean rooms now use flammable and explosive chemical dangerous substances such as methanol, acetone, toluene in the production process, which poses a potential fire threat to clean rooms.
