What are the symptoms of carbon monoxide exposure/poisoning?
Symptoms of low-level CO poisoning include headaches, nausea, weakness, dizziness and confusion. They are similar to what a person might exhibit if affected by the flu or other common illnesses. CO exposure causes a victims blood pressure to rise in an attempt to get more oxygen to the body. As a result, the skin may take on a reddish color. Longer CO exposure can cause lack of coordination, chest pain, vomiting and loss of consciousness. If exposed to CO long enough, coma and death can occur. At what concentration is carbon monoxide considered Immediately Dangerous to Life and Health (IDLH)? According to the National Institute of Occupational Safety and Health (NIOSH), CO is considered IDLH at 1200 parts per million (ppm). When is carbon monoxide monitoring required? The Occupational Safety and Health Administration (OSHA) defines the Permissible Exposure Level (PEL) of CO as 50 ppm in an eight-hour period. Monitoring is advised any time this concentration level might be approached. W
