Fire-fighting measures
Extinguishing agent: fire extinguishing agent with water mist, dry powder, foam or carbon dioxide. Avoid using direct water to extinguish fires. Direct water may cause flammable liquids to splash and spread the fire.
Precautions and protective measures for fire fighting: Firefighters must wear air-contained breathing apparatus, wear full-body fire fighting clothing, and put out fires in the upwind direction. Move the container from the fire scene to an open place as much as possible. If the container in the fire scene has changed color or made a sound from the safety relief device, it must be evacuated immediately. Isolate the scene of the accident and prohibit irrelevant personnel from entering. Contain and process fire fighting water to prevent environmental pollution. [2]
Leak emergency treatment
Protective measures, protective equipment and emergency handling procedures for workers: It is recommended that emergency handling personnel wear air-carrying respirators, anti-static clothing, and rubber and oil-resistant gloves. Do not touch or cross the spill. All equipment used during operation should be grounded. Cut off the source of leakage as much as possible. Eliminate all ignition sources. According to the area affected by liquid flow, steam or dust diffusion, the warning zone shall be delineated, and irrelevant personnel shall be evacuated from the crosswind and upwind direction to the safe area.
Environmental protection measures: contain the leakage to avoid environmental pollution. Prevent leaks from entering sewers, surface water and groundwater.
The containment and removal methods of the leaked chemicals and the disposal materials used:
Small amount of leakage: collect the leaking liquid in a sealable container as much as possible. Absorb with sand, activated carbon or other inert materials, and transfer to a safe place. Do not flush into the sewer.
A large number of leaks: construct a dike or dig a pit for storage. Close the drainage pipe. Cover with foam to prevent evaporation. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
