| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin, eyes and respiratory tract. Inhalation of fine dust will cause severe irritation or caustic burns to respiratory system, skin and eyes. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes. |
| Eye Contact: | Alkaline material causes severe irritation to the eyes. |
| Skin Contact: | Causes severe irritation to the skin |
| Inhalation: | Inhalation of dust causes severe irritating to nose, mucous membranes, and respiratory tract. |
| Ingestion: | Irritates and may cause damage to the digestive tract. austic burns. |
| Acute Health Effects: | With moisture or human contact, hydride rapidly forms caustic alkali hydroxide with evolution of heat. Severe irritation will result. |
| Chronic Health Effects: | No information on chronic effects. |
| 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 with water. Remove contaminated clothes 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: | Remove sources of ignition. Do not raise dust. Mix with vermiculite, sodium carbonate or other suitable dry non combustible adsorbent and sweep up. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store in a tightly sealed container in argon in a cool dry place. Handle in Argon. |
| 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: | Material may form a fine dust. If possible, handle the material in an efficient fume hood. |
