SECTION 3: Hazards Identification
Emergency Overview: Toxic by inhalation, in contact with skin and if swallowed. Material is a strong acid. Severe corrosive to skin and eyes. Acute arsenic toxicity includes nausea, dizziness and coma.
Primary Routes of Exposure: Ingestion, inhalation
Eye Contact: Severely corrosive to the eyes. Contact may result in permanent damage or vision loss.
Skin Contact: Severe corrosive to skin. Material can be absorbed through the skin. Unless treated, contact can lead to deep and painful chemical burns.
Inhalation: Vapors cause severe burns to the nose, mucous membranes and respiratory tract resulting in inflammation, edema, and chemical pneumonitis.
Ingestion: Material is highly corrosive. Ingestion may be fatal unless immediate treatment is available.
Acute Health Effects: Severely corrosive to skin, eyes and respiratory tract, and causes garlic odor, nausea, vomiting, bloody diarrhea, weakness, shock and coma.
Chronic Health Effects: Prolonged exposure to arsenic compounds may cause loss of appetite, dermatitis, diarrhea, kidney and liver damage, nervous disorders, and cancer of the skin, lungs and liver. Hydrolysable fluorine compounds can cause deterioration of bone and tooth structure.
NTP: Yes
IARC: Yes
OSHA: Yes
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.
