First Aid MeasuresBack to Contents
【Ingestion】

Do not induce vomiting - following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child).
【Inhalation】

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
【Skin】

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.
【Eyes】

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

【Inhalation】

Respiratory tract irritation with potential chemical pneumonitis or noncardiogenic pulmonary edema may occur.
【Skin】

Dermal irritation or burns may be seen.
【Eyes】

Eye, nose, and throat irritation may be seen.
【Ingestion】

Esophageal or gi tract irritation or burns may occur.
【Hazards】

This material detonates at 428F or more; ignites by impact. Emits highly toxic fumes of bromides when heated to decomposition. Reacts vigorously with oxidizing materials. Becomes shock-sensitive when mixed with chloropicrin. Unstable, avoid heat, flame, shock, and other chemicals

【Autoignition】

328
【Fire Fighting】

Wear self-contained breathing apparatus and full protective clothing. Move container from fire area if you can do it without risk. Do not get water inside container. Cool containers that are exposed to flames with water from the side until well after fire is out. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire. Isolate for 1/2 mile in all directions if tank car or truck is involved in fire.To extinguish fire use water, foam, carbon dioxide, or dry chemical.
【Fire Potential】

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
