Classification of safety facilities

Safety facilities are divided into 3 major categories, as follows. ⒈Facilities for accident prevention ⑴ Detection and alarm facilities: Alarm devices for pressure, temperature, liquid level, flow rate, composition, etc.; detection and alarm devices for flammable gases, toxic and harmful gases, oxygen, etc.; as well as testing and inspection equipment and instruments used for safety inspections and safety data analysis. ⑵Equipment safety protection facilities: protective covers, shielding screens, load limiters, travel limiters, as well as mechanisms for braking, speed control, lightning protection, moisture prevention, sun protection, freeze protection, corrosion prevention, and leak prevention. There are also safety locking devices for transmission equipment, electrical overload protection devices, and static electricity grounding facilities. ⑶Explosion-proof facilities: Explosion-proof devices for various electrical and instrumentation systems, measures to prevent the entry of combustion-supporting substances (such as nitrogen sealing), systems to prevent the formation of flammable and explosive gases and dusts, as well as explosion-proof equipment and tools. ⑷Protection facilities in the workplace: facilities such as radiation protection, anti-static measures, noise reduction, ventilation (dust and gas removal), protective barriers (nets), anti-slip measures, and protection against burns, etc., in the workplace. ⑸Safety warning signs: include various signs that indicate safety procedures, warn about hazards, as well as signs related to evacuation routes and wind direction. ⒉Facilities for controlling accidents ⑹ Pressure relief and check valves: Devices such as valves, rupture discs, and vent pipes used for pressure relief, as well as valves used for preventing backflow, plus sealing devices for vacuum systems. ⑺Emergency handling facilities: emergency backup power supplies, facilities for emergency shutdown, diversion, discharge (to flares), absorption, neutralization, cooling, etc., facilities for introducing or adding inert gases, reaction inhibitors, etc., as well as emergency shutdown and instrument interlock systems. ⒊Facilities for reducing and eliminating the effects of accidents ⑻ Fire spread prevention facilities: flame arrestors, safety water seals, backflow preventers, oil (fire) barriers, explosion-proof walls and doors and other explosion isolation facilities, firewalls, fire doors, steam curtains, water curtains and other such facilities, as well as fire-resistant material coatings. ⑼Fire extinguishing facilities: water spray, inert gas, steam, foam release and other fire extinguishing systems, fire hydrants, high-pressure water guns, fire trucks, fire water supply networks, fire stations, etc. ⑽Emergency individual protection equipment: eyewash stations, shower systems, escape devices, escape ropes, emergency lighting, and other such facilities. ⑾Emergency rescue facilities: leak sealing equipment, emergency construction equipment, and medical treatment equipment for injured persons at the scene. ⑿Escape and shelter facilities: safety passages (ladders) for escaping and taking shelter, safe shelters (equipped with air breathing systems), shelter signals, etc. ⒀Personal protective equipment and gear: This includes equipment designed to protect the head, face, visual and respiratory organs, as well as the limbs and torso, from physical and chemical hazards in the workplace. Such equipment provides protection against fire, toxins, burns, corrosion, noise, light exposure, falls from heights, impacts, and punctures.
