What is Carbon Monoxide?

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be deadly when inhaled. It is produced by fuel-burning equipment such as generators, heaters, engines, and forklifts, especially in enclosed or poorly ventilated areas.

Symptoms of CO Exposure

• Headache, dizziness, and nausea.
• Fatigue, confusion, and chest pain.
• Loss of consciousness in severe cases.
• Symptoms may be mistaken for flu or fatigue—this makes CO especially dangerous.

Common Sources on Worksites

• Gas-powered tools or equipment in enclosed spaces.
• Generators used indoors or near building air intakes.
• Forklifts, compressors, or vehicles running inside buildings.
• Blocked exhaust vents or inadequate ventilation systems.

Prevention and Protection

• Never use fuel-burning equipment indoors without proper ventilation.
• Install and regularly test carbon monoxide detectors in work areas.
• Turn off engines when not in use and maintain equipment properly.
• Report symptoms immediately and seek fresh air if exposure is suspected.
