Danger

H227: Combustible liquid [Warning Flammable liquids]

Nitriles, such as DIMETHYL CYANAMIDE, may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids. This compound reacts with oxidizers, water, or steam. (NTP, 1992)

4 - Materials that, under emergency conditions, can be lethal.

2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.

1 - Materials that in themselves are normally stable but that can become unstable at elevated temperatures and pressures.

Acute Tox. 3 (100%)

Flammable liquids - Category 4

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. Then, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

CMPD APPEARS TO BE HAZARDOUS, ESP BY SKIN ABSORPTION

The neurotoxic effects of dimethyl cyanamide are weakness and ataxia. /From table/

... ORAL ... IN RATS & GUINEA PIGS ... SYMPTOMS WERE WEAKNESS, ATAXIA, GASPING RESPIRATIONS, & UNCONSCIOUSNESS. IT WAS READILY ABSORBED THROUGH GUINEA PIG SKIN ... WITH LITTLE SKIN IRRITATION. IT WAS NOT SEVERE EYE IRRITANT TO RABBIT. NO SKIN SENSITIZATION WAS PRODUCED IN GUINEA PIG.
