tert-Butylisocyanat

Toxic Gases & Vapors -> Monoisocyanates

Flammable agents - 3rd degree

Tert-butyl isocyanate appears as a clear colorless liquid with a pungent odor. Very toxic by ingestion, may also be toxic by skin absorption and inhalation. Vapors heavier than air. Less dense than water and insoluble in water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion.

Colorless liquid with a pungent odor; [CAMEO]

Excerpt from ERG Guide 155 [Substances - Toxic and/or Corrosive (Flammable / Water-Sensitive)]:

· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Excerpt from ERG Guide 155 [Substances - Toxic and/or Corrosive (Flammable / Water-Sensitive)]:

· TOXIC and/or CORROSIVE; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.

TERT-BUTYL ISOCYANATE can react exothermically with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizing agents, hydrides, phenols, and peroxides. May undergo polymerization with acids and bases. May react with water to form tert-butylamine and carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969].

PG I: the degree of danger presented by the material is great

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

General First Aid:

· Wear positive pressure self-contained breathing apparatus (SCBA).

TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
