Diamond	Hazard	Value	Description
2 2 0	Health	2	Can cause temporary incapacitation or residual injury.
	Flammability	2	Must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
	Instability	0	Normally stable, even under fire conditions.
	Special

Colorless liquid with a slight ammonia-like odor. (USCG, 1999)

none

No rapid reaction with air. No rapid reaction with water.

Special Hazards of Combustion Products: Emits carbon oxides, nitrogen oxides, and dimethylamine when heated to decomposition.

Behavior in Fire: Sealed closed containers may rupture from pressure from heat of fire. (USCG, 1999)

Inhalation may cause nasal and respiratory irritation. May cause systemic poisoning. Ingestion may cause abdominal spasms, vomiting, sweating, weakness, and headache. Large doses may cause lethargy, disorientation, redness, dermatitis, and sensitization. (USCG, 1999)

N,N-DIMETHYL ACETAMIDE SOLUTION is an amide. Incompatible with oxidizing agents and halogenated compounds. Exothermic reactions occur with carbon tetrachloride and hexachlorocyclohexane. It can react violently in the presence of iron. (NTP, 1992) Special Hazards of Combustion Products: Emits carbon oxides, nitrogen oxides, and dimethylamine when heated to decomposition.

Excerpt from 153 [Substances - Toxic and/or Corrosive (Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2020)

Fire Extinguishing Agents Not to Be Used: Do not use halogenated extinguishing media or water.

Fire Extinguishing Agents: Dry chemical, alcohol foam, carbon dioxide (USCG, 1999)

Excerpt from 153 [Substances - Toxic and/or Corrosive (Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2020)

Wear impervious protective clothing, including boots, gloves, and apron or coveralls to prevent skin contact. Use goggles or face shield where splashing is possible. Do not wear contact lenses when working with this compound. (USCG, 1999)
