| Reactivity Alerts | Highly Flammable |
| Reactivity Profile | METHYL NITRITE is an oxidizing agent. A heat-sensitive explosive. [Lewis]. The presence of metal oxides increases the thermal sensitivity. May, if mixed with reducing agents including hydrides, sulfides and nitrides begin a vigorous reaction that culminates in a detonation. Reacts with inorganic bases to form explosive salts. |
| DOT Emergency Guidelines | /GUIDE 116: GASES - FLAMMABLE (UNSTABLE)/ Fire or Explosion: EXTREMELY FLAMMABLE. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. ... Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Cylinders exposed to fire may vent and release flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. |
