Ethylaluminium dichloride
It is easily flammable in the face of air and causes an explosion in the face of water. When burned, it can produce chloride gases and toxic hydrocarbons.
105
Strontium phosphide
Contact with water or moist air produces toxic, flammable phosphine gas, which exothermics in large quantities and causes combustion or explosion.
Water is prohibited, and foam is used to extinguish fires. It can be extinguished with dry powder, soda ash, lime and dry sand.
Fourth, the reaction with water to produce hydrogen chloride substances
106

107
Arsenic trichloride
Decomposes in contact with water and ultraviolet rays, emitting a white smokey irritating and corrosive hydrogen chloride gas. Mixed with metal sodium, potassium and aluminum, it can explode violently after impact. It has strong corrosiveness.
Emergency responders must wear full-body fireproof and anti-poison suits to extinguish the fire in the upwind direction. Fire extinguishing agent: dry sand soil. Water is prohibited.
108
Iodine trichloride
Decomposed by high heat, it emits corrosive and irritating fumes. Moisture absorption or water exposure can produce large amounts of corrosive fumes. Highly corrosive.
Emergency responders must wear full-body acid and alkali-resistant fire suits. Fire extinguishing agent: carbon dioxide, sand.
109
Silicon tetrachloride
110
Trichlorosilane
In case of open flame, it burns strongly. Decomposed by high heat to produce toxic chloride gas. Reacts with oxidants and is in danger of combustion. It is highly volatile, emits smoke in the air, and can produce hot and toxic corrosive fumes when encountered with water or water vapor.
Emergency responders must wear filtered gas masks (full-face masks) or isolated respirators, wear full-body fireproof and gas suits, and extinguish fires in the upwind direction. Fire extinguishing agent: dry powder, dry sand. Do not use water, foam, carbon dioxide, acid and alkali fire extinguishing agents.
111
Sulfoxide chloride
This product is non-combustible, and will release irritating toxic fumes such as sulfur dioxide and hydrogen chloride in case of water or moisture. Decomposition by heat can also produce toxic substances. Corrosive to many metals, especially moist air.
Emergency responders must wear full-body acid and alkali-resistant fire suits. Fire extinguishing agent: carbon dioxide, sand. Water is prohibited.
112
Isobutyl chloroformate
Flammable in case of open flame, high heat. Decomposes in contact with water or heat, releasing toxic and corrosive fumes. Its vapor is heavier than air, and it can spread to a considerable distance at a lower place, and it will be re-ignited in the event of a fire source. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion.
Use dry powder, soluble foam, carbon dioxide, sand to extinguish the fire. Water should not be used.
113
Valeryl chloride
It can react with oxidants. Reacts with water and emits a pungent and corrosive hydrogen chloride gas. In the case of high heat, the high toxicity smoke is explained.
114
Isovaleryl chloride
Its vapor and air can form an explosive mixture, which is very flammable and explosive in case of open flame and high heat. Reacts violently on contact with oxidants. Reacts with water and emits a pungent and corrosive hydrogen chloride gas. In the case of high heat, the high toxicity smoke is explained. Corrosive to most metals when exposed to moisture. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion.
115
Butenediyl chloride (trans) (fumayl chloride)
In case of open flame, high heat can be flammable. It can react with oxidants. Reacts violently with water and emits a pungent and corrosive hydrogen chloride gas. Heat dissipation explains highly toxic fumes. It is easy to self-polymerize, and the polymerization reaction intensifies sharply with the rise of temperature. Corrosive to most metals when exposed to moisture. In case of high heat, the pressure inside the container increases, and there is a risk of cracking and explosion.
