Fire fighting measures
Announce
edit
Inflammable, easy to cause combustion and explosion in case of open fire and high heat.It can react strongly with oxidants.Peroxides with potential explosion risk may be generated when exposed to air or under light conditions.Its vapor is heavier than air, and can spread to a considerable distance at a lower place. It will ignite and recoil when encountering an ignition source.
Move the container from the fire site to an open place as far as possible.Spray water to keep the fire site container cool until the fire is extinguished.If the container in the fire site has changed color or sounds from the safety relief device, it must be evacuated immediately.Extinguishing agent: insoluble foam, dry powder, carbon dioxide, sand.
Leakage emergency treatment
Announce
edit
Evacuate the personnel in the leakage contaminated area to a safe area quickly, isolate them, and strictly restrict access.Cut off the ignition source.It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes.Cut off the leakage source as much as possible.Prevent from flowing into restricted spaces such as sewers and flood discharge ditches.
Small amount of leakage: absorb with activated carbon or other inert materials.A large amount of water can also be used for flushing, and the diluted washing water will be discharged into the waste water system.
Large amount of leakage: build a dike or dig a pit to receive.Cover with foam to reduce steam disaster.Use explosion-proof pump to transfer to tank car or special collector for recycling or transport to waste disposal site.
First aid measures

edit
Skin contact: Take off the contaminated clothes and wash the skin thoroughly with soapy water and clean water.
Eye contact: Lift the eyelid and flush with flowing water or physiological saline.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.
Ingestion: drink enough warm water to induce vomiting.Get medical attention.
