First aid measures
Announce
edit
Skin contact: Take off contaminated clothes immediately and wash with plenty of flowing water.Get medical attention.
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.[1]
Fire fighting measures

edit
Hazard characteristics: it will decompose in acid and emit corrosive hydrogen fluoride gas.It decomposes into highly toxic smoke in case of high heat.
Extinguishing method: firefighters must wear full body fire and gas protective clothing and extinguish the fire upwind.When putting out a fire, try to move the container from the fire site to an open place.Then select appropriate extinguishing agent to extinguish the fire according to the cause of fire.[1]
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear dust masks and gas suits.Do not touch the leakage directly.
Small amount of leakage: avoid raising dust, carefully sweep and transfer to a safe place.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.[1]
Handling and storage
Announce
edit
Operation precautions: closed operation, local exhaust.Prevent dust from releasing into the workshop air.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that operators wear self-priming filter type dust mask, chemical safety goggles, anti poison penetration work clothes and rubber gloves.Avoid dust generation.Avoid contact with oxidants and acids.Provide leakage emergency treatment equipment.Empty containers may leave harmful substances.
Precautions for storage: store in a cool and ventilated warehouse.Keep away from kindling and heat sources.Protect from direct sunlight.Packing and sealing.It shall be stored separately from oxidants, acids and edible chemicals, and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.[1]
