ADDITIONAL INFORMATION
NITROMETHANE CAN DETONATE IF SENSITIZED BY AMINES, ALKALIES, STRONG
ACIDS, AND HIGH TEMPERATURES. IT CAN BE DETONATED BY ADIABATIC
COMPRESSION. THE DRY ALKALI OR AMINE SALTS OF NITROMETHANE ARE SHOCK-
SENSITIVE AND THE SODIUM SALT BURSTS INTO FLAME UPON CONTACT WITH
WATER.

ACUTE EFFECTS
HARMFUL IF SWALLOWED, INHALED, OR ABSORBED THROUGH SKIN.
CAUSES EYE AND SKIN IRRITATION.
VAPOR OR MIST IS IRRITATING TO THE EYES, MUCOUS MEMBRANES AND UPPER
RESPIRATORY TRACT.
ABSORPTION INTO THE BODY LEADS TO THE FORMATION OF METHEMOGLOBIN
WHICH IN SUFFICIENT CONCENTRATION CAUSES CYANOSIS. ONSET MAY BE
DELAYED 2 TO 4 HOURS OR LONGER.
