Carbon monoxide (CO) is an odorless, colorless, and highly toxic gas that can be deadly. In workplace settings, potential sources of CO include faulty heating systems, gas-powered equipment, and vehicle exhaust. Ensuring adequate ventilation, regularly inspecting and maintaining equipment, and providing employee training on CO poisoning symptoms and prevention measures are crucial. CO detectors should be installed in areas with potential CO exposure, and employees should be aware of the signs of CO poisoning, such as headaches, dizziness, nausea, and fatigue. By implementing these safety measures, employers can significantly reduce the risk of CO poisoning in the workplace and protect the health and well-being of their employees.
