| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Cyanides may cause headache, weakness, dizziness, labored breathing, nausea and vomiting, weak and irregular heartbeat, unconsciousness, convulsions, coma and death. Very toxic by inhalation, in contact with skin, and if swallowed. May cause harm to the unborn child. May cause heritable genetic damage. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes. |
| Eye Contact: | Severely irritating to the eyes. Reddening of the eyes and pupil dilation are symptoms of cyanide poisoning. |
| Skin Contact: | Severely irritating to the skin. |
| Inhalation: | Inhalation of large amounts of dust may be fatal. The ability of blood to carry oxygen is diminished. |
| Ingestion: | Cyanides cause symptoms of nausea, confusion, giddiness, lower jaw stiffness, convulsions, paralysis, coma, and respiratory failure. |
| Acute Health Effects: | Irritating to skin, eyes and respiratory tract. Very toxic if inhaled, swallowed or absorbed through the skin. May cause harm to the unborn child. |
| Chronic Health Effects: | Prolonged or repeated skin exposure may cause a cyanide rash and dust may cause nasal sores. May cause heritable genetic damage. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |

| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Sweep up the solid and dispose of properly. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store the material in a tightly sealed container. |
| SECTION 8: Exposure Controls and Personal Protection | |
|---|---|
| Eye Protection: | Always wear approved safety glasses when handling a chemical substance in the laboratory. |
| Skin Protection: | Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove. |
| Ventilation: | Handle the material in an efficient fume hood. Reaction with mineral acids can release toxic fumes of hydrogen cyanide. |
| Respirator: | If ventilation is not available a respirator should be worn. The use of respirators requires a Respiratory Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | Wear a full face shield, lab apron and suitable gloves. |
