Harmful by inhalation, in contact with skin and if swallowed. May ignite spontaneously on contact with air.
Emergency Overview:
Contact with skin may result in severe chemical burns.
Primary Routes of Exposure:Skin and inhalation
Eye Contact:May cause mild to severe irritation of the eyes.
Skin Contact:Harmful in contact with skin. May cause mild irritation of the skin, or thermal burns if ignited.
Inhalation:Harmful by inhalation. Inhalation may lead to dizziness and headaches.
Harmful if swallowed. Ingestion is an unlikely mode of entry as the material is pyrophoric and has a noxious
Ingestion:
odor.
Acute Health Affects:Harmful by inhalation, in contact with skin and if swallowed.

SECTION 4: First Aid Measures
Immediately flush the eyes with copious amounts of water for at least 15 minutes. A victim will need
Eye Exposure:
assistance in keeping their eye lids open. Get immediate medical attention.
Wash the affected area immediately with water. Remove contaminated clothing if necessary. Seek medical
Skin Exposure:
assistance if irritation persists.
Remove victim to fresh air immediately. Keep the victim lying down and warm. Give oxygen as soon as
Inhalation:
possible. If shock occurs, respond with appropriate first aid. Transport the victim to a hospital.
Seek medical attention immediately. Keep the victim calm. Give water to dilute the toxin (only if conscious).

Always wear approved safety glasses. When handling this substance wear a face shield as added protection.
Eye Protection:
Skin Protection:Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.
Ventilation:Material has a pungent odor. Always handle material in an efficient fume hood.
If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator
Respirator:
Protection Program to be in compliance 29 CFR 1910.134.
Ventilation:Material has a pungent odor. Always handle material in an efficient fume hood.
Additional Protection:Wear a full face shield, flame resistant lab apron and suitable gloves.
