Health & Safety Precautions
Sulfide(H2S).Prolongedbreathingof50to100ppmofH2S,(700to1000ppm)onlyafewbreaths of the gas, may lead to unconsciousness and could be fatal. To avoid breathing excessive concentrations of H2S, personnel should stand upwind of tank and bulk transport compartments containing asphalt, keep their faces at least two feet from compartment openings, and avoid breathing vapors when opening hatches and dome covers. Use respiratory equipment where necessary.
Ingestion As a general precaution, if petroleum products are ingested, keep the person calm. DO NOT induce vomiting. Call a physician immediately, identifying the product and approximate amount swallowed. While petroleum products are generally not highly toxic, solvents and light oils with viscosities below 20.5 centistokes (100 SUS) at 37.8oC (100oF) pose a distinct hazard of being aspirated into the lungs and causing chemical pneumonities. This is a delayed effect, which may not occur for day. Because of the accidental swallowing, petroleum products should never be siphoned by mouth. /p>
Skin Contact- Prolonged or repeated contact of petroleum oils, greases, or solvents with the skin can cause skin irritation and dermatitis. In case of skin contact, wash skin thoroughly with soap and warm water. A waterless hand cleaner and a soft skin brush can be used to help remove oils and greases. For certain products, dry-wiping is advised before using waterless hand cleaner. Refer to the product MSDS for specificinstructionsandprecautions.Promptlyremove petroleum-soaked clothing and launder before re-use.

If prolonged contact with petroleum products is unavoidable, wear chemical-resistant gloves, apron, splash goggles, and other protective clothing.
High-pressure injection of grease through the skin (a grease gun injury) can cause serious delayed damage to soft tissues. Hydraulic oil under high pressure can cause similar injury. Regardless of the size or appearance of the wound, a physician should be contacted immediately, as treatment may require surgical intervention.
Chronic Health Effects- Although not the cases with many highly or well refinedpetroleumoils, studies with laboratory animals have shown that prolonged exposure to certain petroleum products can cause cancer and other chronic health effects. Some petroleum oils and distillates have caused skin cancer in mice following skin painting tests over the animals” lifetime. In similar tests, used motor oil also has caused skin cancer. Carefully check the product MSDS for such warning information.
ADDITIONAL HEALTH AND SAFETY RECOMMENDATIONS
You can protect yourself from petroleum-related hazards by exercising care and common sense in the handling of petroleum products. Appropriate engineering controls, work practices, and personal protection should be used to minimize skin contact and to keep exposure by inhalation as far below the recommended occupational exposure limit as is reasonably practical.
