Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. With clean shovel place material into clean, dry container and cover loosely; move containers from spill area.
Small Fires: Dry chemical, carbon dioxide, sand, earth, water spray or regular foam. Large Fires: Water spray, fog or regular foam.
Flammable/combustible material. May be ignited by friction, heat, sparks or flames.
Fire may produce irritating and/or toxic gases.
Headache, fatigue, numbness, and aching limbs have occurred in workers. Peripheral and central nerve damage may occur.
Nausea, diffuse pain, and indigestion have been reported in workers with prolonged exposure to biphenyl.
Respiratory tract irritation and bronchitis have been reported.
Percutaneous absorption through intact skin has been noted.
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). Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
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.
