Personal precautions, protective equipment and emergency procedures
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Cover the spilled material with dry non-combustible inert absorbent. Sweep spilled substance into covered plastic containers. Do NOT wash away into sewer.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Precautions for safe handling
NO contact with water. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Keep in a well-ventilated room. Dry. Well closed. Separated from food and feedstuffs.
Control parameters
Occupational Exposure limit valuesTLV: 0.5 mg/m3, as TWA; A4 (not classifiable as a human carcinogen).MAK: (inhalable fraction): 1 mg/m3; peak limitation category: II(2); skin absorption (H); pregnancy risk group: C
no data available
Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear safety goggles or eye protection in combination with breathing protection if powder.
Protective gloves.
Use local exhaust or breathing protection.

Possibility of hazardous reactions
Decomposes under the influence of water. This produces cyanamide (see ICSC 0424), ammonia, calcium hydroxide and acetylene. This generates fire and explosion hazard. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
