Brandgefahren	Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. Explosive.
Brandpotenzial	Spontaneously combustible.
Gesundheitsgefahren	Excerpt from NIOSH Pocket Guide for Dichloroacetylene:
Gefahrenübersicht	Dichloroacetylene is formed from the thermal decomposition of trichloroethylene or tetrachloroethane. Dichloroacetylene poisoning causes injury to the kidneys and nervous system. Affected patients may have trigeminal nerve paralysis and reactivation of facial herpes. Most cases were reported when trichloroethylene was used as an anesthetic. [ACGIH]

Reactivity Alerts	Explosive
Reactivity Profile	DICHLOROACETYLENE is a reducing agent. Incompatible with oxidizing agents. Can ignite or explode on contact with air or if heated. Can explode if shocked. Burns in the presence of chlorine to form phosgene (Ann. Chem. 640:5(1961)).
Chemical Dangers	May decompose explosively on shock, friction or concussion. May explode on heating. Decomposes on heating. This produces toxic fumes including chlorine. Reacts violently with oxidants and acids.
Flammable Limits	Combustible Liquid
