Clean rooms are increasingly being used in various areas of China in various industries such as electronics, biopharmaceuticals, aerospace, precision machinery, fine chemicals, food processing, health care products and cosmetics production, and scientific research, providing clean production environments, clean experimental environments . The importance of clean environment creation is increasingly recognized or recognized by people. La mayoría de las salas limpias están equipadas con equipos de producción y equipos experimentales de investigación científica de diversos grados y que utilizan diversos medios de proceso. Many of them are valuable equipment and valuable instruments. Not only the construction cost is expensive, and some flammable, explosive, and hazardous process media are often used; at the same time, according to the requirements for human and material cleanliness in clean room, the passages of the clean room (area) are generally moved back and forth, making personnel evacuation difficult. Due to its airtightness, once a fire occurs, it is not easy to be discovered from the outside, and it is difficult for firefighters to approach and enter. Therefore, it is generally believed that the installation of fire safety facilities in clean rooms is very important, and it can be said to be the top priority in ensuring the safety of clean rooms, is a safety measure to prevent or avoid major economic losses in clean rooms and serious damage to personnel's lives due to the occurrence of fire. Se ha vuelto un consenso instalar sistemas de alarma contra incendios y diversos dispositivos en salas blancas, y es una medida de seguridad indispensable. Por lo tanto, actualmente se instalan "sistemas automáticos de alarma contra incendios" en salas blancas recién construidas, renovadas y ampliadas. Las disposiciones obligatorias contenidas en las "Especificaciones de diseño de edificios de fábricas". Los detectores de alarma contra incendios deben instalarse en el piso de producción, el entresuelo técnico, la sala de máquinas, el edificio de la estación, etc. de la sala limpia.
Manual fire alarm buttons should be installed in production areas and corridors of clean workshops. The clean room should be equipped with a fire duty room or control room, which should not be located in clean area. La sala de bomberos debe estar equipada con una centralita telefónica especial para protección contra incendios. El equipo de extinción de incendios y las conexiones de las líneas de la sala limpia deben ser fiables. The control and display functions of the control equipment , should comply with the relevant provisions of the current national standard "Design Code for Automatic Fire Alarm Systems". This requires that fire alarms in clean rooms (areas) should be verified and the following fire linkage controls should be carried out: the indoor fire pump should be started and its feedback signal should be received. In addition to automatic control, manual direct control devices should also be set up in the fire control room; electric fire dampers at relevant parts should be closed, corresponding air conditioning circulation fans, exhaust fans and fresh air fans should be stopped, and their feedback signals should be received; relevant parts should be closed such as electric fire doors and fire shutter doors. Se debe controlar el encendido de las luces de emergencia de respaldo y de las señales de evacuación. En la sala de control de incendios o en la sala de distribución de bajo voltaje, el suministro de energía no contra incendios a las partes relevantes debe cortarse manualmente; el altavoz de emergencia contra incendios debe encenderse para transmisión manual o automática; Se debe controlar el ascensor para que baje al primer piso y se debe recibir su señal de retroalimentación.
In view of the requirements of the product production process and the clean room (area), the necessary cleanliness level should be maintained. Por lo tanto, se enfatiza en la sala limpia que después de las alarmas del detector de incendios, se debe llevar a cabo una verificación y control manual. When it is confirmed that a fire has actually occurred, , the linkage control equipment set up according to regulations operates and feeds back signals to avoid causing large losses. Los requisitos de producción en las salas blancas son diferentes a los de las fábricas normales. Para salas (áreas) limpias con estrictos requisitos de limpieza, si el sistema de purificación de aire acondicionado se apaga y se restablece nuevamente, la limpieza se verá afectada, lo que hará que no pueda cumplir con los requisitos de producción del proceso y cause pérdidas.
Normalmente, los detectores de incendios sensibles a la temperatura son menos sensibles a la detección de incendios que los detectores de humo. Los detectores de incendios sensibles al calor no responden a incendios latentes y sólo pueden responder después de que la llama alcanza un cierto nivel. Therefore, temperature-sensitive fire detectors, fire detectors are not suitable for protecting places where small fires may cause unacceptable losses, but temperature-sensitive fire detection is more suitable for early warning of places where the temperature of an object changes directly. Los detectores de llamas responderán mientras haya radiación de la llama. En lugares donde los incendios van acompañados de llamas abiertas, la respuesta rápida de los detectores de llamas es mejor que los detectores de incendios con detección de humo y temperatura, por lo que en lugares donde las llamas abiertas son propensas a arder, como los detectores de llamas, se utilizan principalmente en lugares donde los gases combustibles se utilizan.
Clean rooms for LCD device panel manufacturing and optoelectronic product manufacturing often require the use of a variety of flammable, explosive, and toxic process media. Therefore, fire alarms and other fire safety facilities have made more provisions in "Design Code for Clean Workshops in Electronic Industry". The number of clean rooms in electronics industry belongs to Category C production plants and should be classified as "secondary protection level". However, for clean rooms in electronic industry such as chip manufacturing and liquid crystal display device panel manufacturing, due to the complex production processes of such electronic products, some production processes require the use of a variety of flammable, chemical solvents, flammable, toxic gases , gases especiales. Once a flood occurs, heat has nowhere to leak and the fire spreads quickly. The fireworks will spread rapidly along air ducts, and the production equipment in factory building is very expensive, so it is very important to strengthen the fire alarm system setting of the clean room. Por lo tanto, se estipula que cuando el área de la zona de protección contra incendios exceda las regulaciones, el nivel de protección debe elevarse al nivel uno.
