Fire hazard of liquid chlorine
Thread Content
I would like to ask the teachers: How is the fire hazard of liquid chlorine classified? Which categories does it belong to? Can a water spray system be installed around the exterior of the enclosed building where liquid chlorine is loaded into tank trucks?
Liquid chlorine is also a strong oxidizing agent. According to the classification of fire hazards for items stored in factories and warehouses as specified in the building design fire protection codes, it falls under Category B, Subcategory 3: strong oxidizing agents that are not classified as Category A. Right?

It is usually designed as Category B with a fire resistance rating of Grade 2 for buildings. It is possible to consider installing alkali water curtain sprayers around the tank truck parking area, as well as setting up an indoor exhaust system.
Category B, see Table 3 in the explanatory notes to Article 3.1.2 of the Code for Fire Protection Design of Buildings. The use of alkaline water is not recommended, as it hinders emergency response and rescue efforts, and may also injure people in the vicinity. Water spray prevents spread, primarily by relying on emergency shut-off valves to cut off the material flow
Chlorine is non-flammable, but it can accelerate combustion. For dealing with liquid chlorine leaks, the guidelines outlined in Document No. 35 of Shandong Province (Guidelines for the Safe Renovation of Liquid Chlorine Storage Facilities and Related Equipment, as well as Emergency Response to Liquid Chlorine Leaks (Trial Version)) should be followed. The emergency response to such leaks is based on the principle of \"prioritizing leak sealing, complementing this with transfer of liquid to another container, using agents to absorb any residual chlorine, and employing water screens as a final safeguard.\"
According to building codes, liquid chlorine is classified as a Class B oxidizing gas
