[Ingestion] Dilution: 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. | |
[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. | |
[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. | |
[Storage] Keep tightly closed. Store in a cool and dry place. | |
[Handling] 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. | |
[Inhalation] Respiratory tract irritation and bronchitis have been reported. | |
[Skin] Percutaneous absorption through intact skin has been noted. | |
[Eyes] Eye and mucous membrane irritation may occur. | |
[Ingestion] Nausea, diffuse pain, and indigestion have been reported in workers with prolonged exposure to biphenyl. | |
[Hazards] Fire may produce irritating or poisonous gases. | |

[Usage] Terphenyl mixtures are used industrially as heat storage and transfer agents, as textile dye carriers, and as intermediates in the production of nonspreading lubricants. From 1960-1970, technical grade terphenyls were used as coolants for nuclear reactors, whereas contemporary use has been in solar-heating systems. Terphenyl mixtures. | |
