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.
In experimental animal studies, PAHs and metabolites cross the placenta. Female offspring of experimental animals exposed to PAHs during pregnancy have a decrease in the number of functional oocytes, sometimes such that they are infertile. <br>PAHs are lipophilic and are excreted in breast milk, allowing for secondary exposure of nursing infants, although the potential significance of such exposure has not been determined.
Leukoplakia and cancers of the lip and oral cavity can develop with chronic exposure.
Irritation, chronic cough, bronchitis, and bronchogenic cancer can occur with chronic exposure.
Coal tar warts (precancerous lesions enhanced by uv light exposure), erythema, dermal burns, acneiform lesions, photosensitization and cancer may develop following chronic exposure.
Toxicity from these substances involves chronic exposure, toxicity after acute ingestions is unlikely and gastric decontamination is generally not indicated.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.
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.
