7. CO is an insidious poison that is released when fuels are burnt It is a colorless odorless tasteless gas and therefore very difficult to detect with the human senses CO kills hundreds of people each year and injures many more It binds to the hemoglobin in the blood and reduces the amount of oxygen being circulated in the body In high concentrations CO can kill in minutes CO is produced by the incomplete combustion of fuels such as wood charcoal coal heating oil paraffin petrol natural gas propane butane etc Examples of CO sources Running engine in garage Gas appliances Oil and Gas furnaces Portable generators Wood stoves Gas or kerosene heaters Barbecues Clogged chimneys Wood and gas fireplaces Heating boiler 4 SYMPTOMS OF CO POISONING The following symptoms may be related to CO poisoning 35 ppm The maximum allowable concentration for continuous exposure for healthy adults in any 8 hour period 200ppm Slight headaches fatigue dizziness nausea after 2 3 hours 400ppm_ Frontal headaches within 1 2 hours life threatening after 3 hours 800ppm Dizziness nausea and convulsions within 45 minutes Unconsciousness within 2 hours Death within 3 hours 1600ppm Headache dizziness and nausea within 20 minutes Death within 1 hour 6400ppm Headache dizziness and nausea within 1 2 minutes 5 LOCATING THE CO ALARM JB C888 Carbon Monoxide alarm is designed to detect the toxic CO fumes that result from incomplete
