Fire fighting measures
Announce
edit
Extinguishing agent:
one
Use water mist, dry powder, foam or carbon dioxide extinguishing agent to extinguish the fire.
two
Avoid using direct water to extinguish the fire. Direct water may cause splashing of flammable liquid and spread the fire.
Precautions and protective measures for fire fighting:
one
Firefighters must wear breathing apparatus and full body fire-fighting clothes to extinguish the fire in the upwind direction.
two
Move the container from the fire site to an open place as far as possible.
three
If the container in the fire site has changed color or sounds from the safety relief device, it must be evacuated immediately.
four
Isolate the accident site and prohibit irrelevant personnel from entering.Receive and treat fire water to prevent environmental pollution.
Leakage emergency treatment
Announce
edit
Protective measures, protective equipment and emergency response procedures for operators:
one
It is recommended that emergency treatment personnel wear gas breathing apparatus, anti-static clothing and rubber oil resistant gloves.
two
Do not touch or cross the leakage.
three
All equipment used in operation shall be grounded.
four
Cut off the leakage source as much as possible.
five
Eliminate all ignition sources.
six
The warning area shall be demarcated according to the influence area of liquid flow, steam or dust diffusion, and irrelevant personnel shall evacuate from crosswind and upwind to the safety area.
Environmental protection measures:
one
Collect leakage to avoid environmental pollution.Prevent leakage into sewers, surface water and groundwater.
two
The method of receiving and removing leaked chemicals and the disposal materials used: small amount of leakage: the leaked liquid shall be collected in airtight containers as far as possible.Absorb with sand, activated carbon or other inert materials and transfer to a safe place.Do not flush into the sewer.Large amount of leakage: build a dike or dig a pit to receive.Close the drainage pipe.Cover with foam to inhibit evaporation.Use explosion-proof pump to transfer to tank car or special collector for recycling or transport to waste disposal site.
