How safe is Sodium Metabisulphite?

  • Fire hazard: not combustible
  • Exposure: Can cause redness and pain if in contact with eyes and skin, and it may result in abdominal pain, vomiting and respiratory difficulties if inhaled or ingested.
  • Chemical hazards: this compound can release toxic fumes on decomposition, and reacts violently with oxidants and acids
  • First aid measures include immediate washing of affected area with copious amounts of water if in contact with skin or eyes. If inhaled or ingested give patient water to drink and seek medical help.
  • In case of fire involving sodium metabisulphite the best option is to use chemical, dry sand or carbon dioxide fire extinguishers. Water should not be applied directly to the flames, but can be used as a distance to control the spread of the fire.
