Concentrations of 1 to 2 ppm may be found in homes with a normally operating gas furnace, to well over 1,000 ppm in homes with a faulty furnace. Just 200 ppm CO over 2 to 3 hours can cause slight headache, fatigue, dizziness, and nausea. Carbon Monoxide testing is a crucial service provided by HVAC/R technicians. More About CO Carbon monoxide poisoning is one of the leading causes of sickness and death each year. CO is the by-product of incomplete combustion in heating and cooking appliances, as well as gasoline, natural gas, and propane powered engines. Carbon monoxide is a colorless, tasteless, invisible toxic gas, which can cause serious health problems. The following chart depicts the health effects of exposure to CO:
• 0 ppm-Desired level
• 9 ppm-Acceptable limit above ambient condition in living areas (ASHRAE)
• 50 ppm-Limit for continuous exposure in any 8 hour period (OSHA)
• 400 ppm-Frontal headaches 1-2 hours
• 800 ppm-Nausea and convulsions, death within 2 hours
• 1600 ppm-Nausea within 20 minutes, death within 1 hour
• 12800 ppm-Death within 1-3 minutes
