TYPES OF HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Not combustible (impurities constitute a fire risk). Gives off irritating or toxic fumes (or gases) in a fire. | NO contact with water. | Use dry powder. NO carbon dioxide, foam, water. |
| EXPLOSION | Risk of fire and explosion on contact with water or metals. | ||
| EXPOSURE | STRICT HYGIENE! | ||
| Inhalation | Cough. Burning sensation. Sore throat. See Notes. | Use local exhaust or breathing protection. | Fresh air, rest. |
| Skin | Redness. | Protective gloves. | Remove contaminated clothes. Rinse skin with plenty of water or shower. |
| Eyes | Redness. Pain. | Wear safety goggles or eye protection in combination with breathing protection if powder. | Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Blue haze and halo. |
| Ingestion | Sore throat. Burning sensation in the throat and chest. Abdominal pain. See Notes. | Do not eat, drink, or smoke during work. | Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention . |

This substance may be hazardous to the environment. Special attention should be given to aquatic organisms. |
| NOTES |
|
In combination with even small amounts of alcohol the substance causes effects on cardiovascular and central nervous systems resulting in flushing, palpitation, hypotension and hyperventilation. The effects may be delayed. Commercial calcium cyanamide is a crystalline substance which contains trace amounts of calcium carbide which may produce acetylene in production vessels or containers. Reacts violently with fire extinguishing agents such as water. UN 1403: Calcium Cyanamide with more than 0.1% calcium carbide. Card has been partially updated in January 2008: see Occupational Exposure Limits. |
