Key Hazards
- Carbon monoxide buildup from vehicle exhaust
- Exhaust entering buildings, garages, trailers, or confined areas
- Idling near doors, windows, vents, or air intakes
- Workers exposed while warming vehicles or using equipment
- Public or pedestrian exposure near idling vehicles
- Fire or burn hazards from hot exhaust components
2–3 Minute Talk Script
Vehicle exhaust can contain carbon monoxide and other harmful gases. Idling may seem harmless, but exhaust can build up quickly in the wrong location.
Vehicles should not idle inside garages, shops, warehouses, trailers, or enclosed areas unless the exhaust is properly controlled and the setup is approved.
Drivers should consider where exhaust is going before leaving a vehicle running. Exhaust should be kept away from doors, windows, vents, air intakes, trenches, pits, and occupied areas.
Carbon monoxide has no color or odor, so workers may not realize they are being exposed until symptoms occur.
Symptoms of carbon monoxide exposure can include headache, dizziness, nausea, weakness, confusion, or shortness of breath. Workers should move to fresh air and report symptoms immediately.
Idling should be minimized when it is not needed for work, safety, temperature control, or equipment operation.
Hot exhaust parts should be kept away from dry grass, leaves, paper, plastic, fuel, chemicals, and other combustibles.
Safe vehicle idling and exhaust control depends on ventilation, vehicle placement, awareness of air intakes and enclosed spaces, and shutting vehicles off when idling creates exposure or fire hazards.
Safety Reminders
- Do not idle vehicles in enclosed areas without approved exhaust control.
- Keep exhaust away from doors, windows, vents, and air intakes.
- Watch for carbon monoxide symptoms.
- Move to fresh air if exposure is suspected.
- Minimize unnecessary idling.
- Keep hot exhaust away from combustibles.
- Consider nearby workers, pedestrians, and occupied spaces.
Ask the Crew
- Where is the vehicle exhaust going?
- Could exhaust enter a building, trailer, pit, or enclosed area?
- Are workers or the public near the exhaust path?
- Is idling necessary for the task?
- What should workers do if carbon monoxide symptoms appear?
