What you need to know about safe evacuation in Dongguan cleanroom
There is also an important problem in the layout. Although it is not specifically pointed out in the GMP, as a dust-free workshop building with a complex plane, it must be noted that it is safe evacuation.
(I) Features of Dongguan Clean Room:
1. The space is closed. If a fire occurs, it is extremely unfavorable for evacuation and fire fighting. At the same time, because the heat leaks nowhere, the heat radiation of the fire source is reflected by the four walls to make the room heat up rapidly, which greatly shortens the time for the materials in all parts of the room to reach the ignition point. When there is no window on the exterior wall of the factory building, fires that occur indoors are often not easy to be discovered by the outside world, and it is not easy to select a rescue breakthrough after discovery.
2. Several clean rooms are colluded with each other through air ducts. When a fire occurs, especially when the fire is not detected at the beginning and continues to be ventilated, the air ducts become an important channel for smoke and fire to quickly escape, simmer, and other rooms. .
3. The tortuous plane layout increases obstacles on the evacuation route and extends the distance and time for safe evacuation.
(II) Fire-proof partition of Dongguan clean room:
According to the "Code for Fire Protection of Architectural Design" and "Code for Design of Dust-Free Workshops", the fire resistance level of Dongguan's dust-free workshops should not be lower than that of general-level reinforced concrete frame structures that meet the requirements of secondary fire-resistance levels. According to the danger of fire, the production is divided into four categories: A, He, C, and D. In the pharmaceutical industry, the production of bulk pharmaceuticals uses organic solvents such as gasoline and ethanol, such as penicillin refining sites, and non-nacetin workshops in API plants. Hydrocarbonation, recovery and inductive distillation parts, borneol, saponin, analgin, vitamin B. Refined parts. A large number of organic solvents such as ethanol and acetone are used in the production of antibiotics, such as penicillin refining plants, doxycycline refining plants, etc., which are all class A. According to the fire hazard category, it is possible to determine the area of defense industry in the layout. After the fire, the temperature rises extremely quickly in half an hour. The duration of the initial stage of the fire of the non-combustible structure is within 5 to 20 mln. The ignition point is still partially burned. The fire is unstable and may be interrupted. Therefore, this period of time is extremely important for personnel evacuation and rescue of supplies. Considering that the crowd walking speed on the flat ground is about 16m / m, the stairs are 10m / mm, and the obstacles on the way are added. If the evacuation distance is controlled to be 50m, the evacuation can be completed in about 4min. Of course, this also needs to have obvious guidance signs and emergency lighting evacuation distances to determine the location of the safety exit.
