Safety Profile
Confirmed carcinogen with carcinogenic data reported. Poison by intraperitoneal route. Moderately toxic by ingestion, inhalation, and sh contact. Experimental teratogenic and reproductive effects. A skin irritant. Human mutation data reported. Animal experiments suggest somewhat lower toxicity than for related epoxy compounds. Readdy absorbed through the skin. Causes nervous excitation followed by depression. Explodes when heated or in the presence of strong acids,bases, metals (e.g., copper, zinc), and metal salts (e.g., aluminum chloride, iron(II1) chloride, tin(Iy chloride). When heated to decomposition it emits acrid smoke and fumes. See also DIGLYCIDYL ETHER.
