Accidental Release Measures

General Information: Use proper personal protective equipment.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Provide ventilation.

Cyanic acid (also called fulminic acid) is an unstable - explosive, poisonous, volatile, clear liquid with the structure of H-O-C?N - the oxoacid formed from the pseudohalogen cyanide, which readily polymerizes to cyamelide and fulminic acid. Cyanuric acid (also called pyrolithic acid), white monoclinic crystal with the structure of [HOC(NCOH)2N], is the compound of polymerized cyanic acid.

Cyanic acid hydrolyses to ammonia and carbon dioxide in water. Its salts and esters are cyanates. Esters of normal cyanic acid are not known. There is another isomeric cyanic acid with the structure of H-N=C=O, which is called isocyanic acid. Its salts and esters are isocyanates.

Cyanates are used in the manufacturing pharmaceuticals, pesticides, textile softener, lubricants and industrial disinfectants through the conversion to polycyclic compounds.

Used as plastic additives and as heat treatment salt formulations for metals. In chemcial reaction, sodium cyanate is used for the synthesis urea derivatives mainly and other pesticide and dyes intermediates. It is used directly as a herbicide.

• Meta Uriedo Aniline & isoproturon & other herbicides products

• Urea derivatives are obtained by reaction with amines.

• Herbicides, Mainly to destroy weeds in lawns and onion crops, Simultaneously it act as fertilizer.

• It is also used in the syntheses of pesticides, detergents and plastic additives.

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid breathing dust.
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.

Exposure Limits

OSHA Vacated PELs: Sodium cyanate: No OSHA Vacated PELs are listed for this chemical. Sodium carbonate: No OSHA Vacated PELs are listed for this chemical.
Personal Protective Equipment

Disposal Considerations

Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification.
