Section 3: Hazards Identification
Irritating to skin, eyes and respiratory tract. Inhalation of fine dust will cause severe irritation or caustic burns to
Emergency Overview:
respiratory system, skin and eyes.
Primary Routes of Exposure: Contact with skin and eyes. Inhalation of dust
Eye Contact: Corrosive to eyes. May cause severe eye damage.
Skin Contact: Causes severe irritation and chemical burns to the skin.
Inhalation: Harmful by inhalation. Dust causes severe irritation to the nose, mucous membranes and respiratory tract.
Ingestion: Harmful if swallowed. Material reacts with moisture causing chemical burns to the mouth and throat.
With moisture or human contact, hydride rapidly forms caustic alkali hydroxide with evolution of heat. Severe

irritation or chemical burns will result.
Chronic Health Affects: No information on long-term chronic effects.
NTP: No
IARC: No
OSHA: No
SECTION 4: First Aid Measures
Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need
Eye Exposure:
assistance in keeping their eye lids open. Get immediate medical attention.
Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if
Skin Exposure:
irritation persists.
Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty
Inhalation:
in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance.
Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce
Ingestion:
vomiting only if directed by medical personnel.
