Used motor oil vapours are moderately irritating to the eyes. The primary concern with exposure to used motor oil is the possibility of skin cancer development following prolonged skin contact. Other toxic effects may be observed depending on the presence of other contaminates in the oil. No OEL currently published in Alberta 5. Contamination with large amounts of unburned or partially burned fuel may increase flammability.
Fire hazard is slight under normal conditions.
For larger fires use water fog or foam. The direct application of streams of water are likely to spread the fire. Respiratory, fire retardant clothing, and eye protection required for fire fighting personnel. Wear chemical goggles. Otherwise, use air purifying or air supplied respirator.
