SECTION 3: Hazards Identification
Emergency Overview: Irritating to eyes, skin and respiratory tract. May evolve ammonia, a choking gas, if exposed to water. May be harmful if swallowed
Primary Routes of Exposure: Ingestion, inhalation, skin, eyes.
Eye Contact: Causes severe eye irritation.
Skin Contact: Causes severe skin irritation. May be harmful if absorbed through the skin.
Inhalation: Inhalation causes inflammation of the respiratory tract, edema and chemical pneumonitis. Inhalation may be fatal.
Ingestion: May cause nausea, vomiting and gastrointestinal tract burns, perforation and peritonitis, with abdominal pain.
Acute Health Effects: Severe irritant to skin, eyes and respiratory tract. Ingestion causes damage to the mouth, throat, esophagus and gastrointestinal tract. Inhalation may lead to inflamation, edema and chemical pneumonitis.
Chronic Health Effects: Prolonged inhalation of inorganic silicon compounds may cause pulmonary fibrosis know as silicosis.
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.
