Sulfuryl chloride | SO2Cl2 - PubChem

Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]: When material is not involved in fire, do not use water on material itself. SMALL FIRE: Dry chemical or CO2. Move containers from fire area if you can do it without risk. LARGE FIRE: Flood fire area with large quantities of water, while knocking down vapors with water fog. If insufficient water supply: knock down vapors only.Read more

Bentonite - Wikipedia

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent swelling clay consisting mostly of montmorillonite usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. Bentonite beds are white or pale blue or green in fresh exposures, turning to a cream color and then yellow, red, or brown as the exposure is weathered ...Read more
