Butyl nitrite, toxicity

Note - It is a good idea to have a supply of cyanide antidote ready in case you are affected by the fumes. These are sodium thiosulfate, a common photographic chemical, and amyl nitrite, a heart drug. Butyl nitrite is available in some "sex" shops as a room odorant, and may be substituted for the amyl nitrite. A few hours before beginning production of the actual cyanide, take a capsule containing 500 mg of sodium thiosulfate. It is comparatively non-toxic, but may cause a small bout of "egg burps". 

SAFETY PROFILE Moderately toxic by ingestion, inhalation, and intraperitoneal routes. Mutation data reported. Flammable when exposed to heat or flame or by spontaneous chemical reaction. An oxidizer. Potentially explosive. To fight fire, use water, spray, foam, dry chemical. When heated to decomposition it emits toxic fumes of NOx. See also n-BUTYL NITRITE, NITRITES, and ESTERS. 

Butyl nitrite is a poison by ingestion and intraperito-neal routes. It is mildly toxic by inhalation. When heated to decompose, it emits toxic fumes of nitrogen oxides. 

Amyl butyl, and isobutyl nitrite are less toxic than organic solvents and not as flainmablc. They should be used only with good ventilation and not breathed continuously...
