Service Stations and Vehicle-Repair Facilities
Why am I being warned about potential exposure to chemicals at service stations and vehicle-repair facilities?
Service stations and vehicle-repair facilities can expose you to chemicals when motor vehicles are being fueled, serviced or repaired.
Examples of chemicals you may be exposed to at service stations and vehicle-repair facilities include:
- Benzene. This chemical is present in gasoline and released during fuel combustion. Gasoline vapors containing benzene can enter the air during refueling when the vehicle’s gas cap is removed, if fuel is spilled on the ground, or if a gasoline pump’s vapor-recovery system is not functioning properly.
- Carbon monoxide. This gas is formed during the combustion of gasoline and other fuels.
- Exhaust from diesel and gasoline engines, which contains a mixture of chemicals.
How does exposure to chemicals at service stations and vehicle-repair facilities occur?
- During pregnancy, chemicals found at service stations and vehicle-repair facilities can pass from mother to baby.
How can I reduce my exposure to chemicals at service stations and vehicle-repair facilities?
- Stay no longer than necessary at service stations, as engine exhaust and gasoline vapors are likely to be in the air. Stay out of work areas while at vehicle-repair facilities.
- When refueling your vehicle, stand a few steps away from the nozzle to reduce exposure to any vapors that might be released into the air. Do not “top off” your vehicle after the fuel pump shuts off automatically, as this will release vapors into the air. After refueling, make sure the gas cap for your fuel tank is fully closed. Instructions for properly closing the gas cap are often found on or near the cap.
- If gasoline gets on your clothing, remove the contaminated item as soon as possible. Wash your hands and areas of skin that may have come into contact with the gasoline.
