SECTION 3: Hazards Identification
Emergency Overview: Harmful by inhalation, in contact with skin and if swallowed. Inhalation of vapors may depress central nervous system. Possible risk of harm to the unborn child and impaired fertility.
Primary Routes of Exposure: Ingestion, inhalation, eyes, skin
Eye Contact: Contact will cause irritation, redness and a burning sensation.
Skin Contact: Contact with the skin will result in local irritation. May be absorbed through the skin.
Inhalation: Harmful by inhalation. Inhalation may depress the central nervous system causing difficulty in walking, and irritation to the lungs.
Ingestion: Harmful if swallowed. Ingestion may cause gastrointestinal irritation, nausea, vomiting and headache.
Acute Health Effects: Irritating to skin, eyes and respiratory tract. Ingestion may cause gastrointestinal irritation, nausea, vomiting. Possible risk of harm to the unborn child.
Chronic Health Effects: No information available on long term exposure to this material. Possible risk of impaired fertility.
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 15 minutes. A victim will 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 victim to fresh air immediately. Keep the victim lying down and warm. Give oxygen as soon as possible. If shock occurs, respond with appropriate first aid. Transport the victim to a hospital.
Ingestion: Seek medical attention immediately. Keep the victim calm. Give water to dilute the toxin (only if conscious). Induce vomiting only if directed by medical personnel.
