Sodium sulfite manufacturers inform you about contact protection and fire protection measures of sodium metabisulfite

Contact control and personal protection

Occupational exposure limit

TLVTN: 5mg/m3

Engineering control: The production process is closed and ventilation is strengthened.

Respiratory system protection: When the dust concentration in the air exceeds the standard, self-priming filter dust masks must be worn. An air respirator should be worn during emergency rescue or evacuation.

Eye protection: Wear chemical safety glasses.

Body protection: Wear work clothes with anti-poison penetration.

Hand protection: wear rubber gloves.

Other protection: change work clothes in time. Maintain good hygiene habits.

Disposal

Regulatory Information

Regulatory Information Regulations on the Safety Management of Chemical Dangerous Goods (promulgated by the State Council on February 17, 1987), Implementation Rules for the Regulations on the Safety Management of Chemical Dangerous Goods (Hualuofa [1992] No. 677), Regulations on the Safe Use of Chemicals in the Workplace ([1996] Ministry of Foreign Affairs No. 423) and other regulations have made corresponding regulations on the safe use, production, storage, transportation, loading and unloading of chemical dangerous goods.

Fire protection measures of sodium metabisulfite

Dangerous characteristics: It has strong reducibility. It can react with strong oxidants such as chromic anhydride, chlorate and potassium permanganate, etc., which can cause a strong reaction, causing combustion or explosion.

Hazardous combustion products: sodium oxide (Na2O) and sulfur dioxide (SO2)

Combustion equation: Na2S2O5+O2—ignite—2SO2+Na2O

Fire extinguishing method: Firefighters must wear full-body fireproof and anti-virus suits and extinguish the fire in the upwind. When extinguishing the fire, move the container from the fire site to an open place as much as possible.
