Recommendations may be superseded by new developments in these fields readers are therefore advised to regard these recommendations as general guidelines and to determine whether new information is available. * OSHA Note: This guideline summarizes pertinent information about carbon monoxide for workers and employers as well as for physicians, industrial hygienists, and other occupational safety and health professionals who may need such information to conduct effective occupational safety and health programs. Occupational Safety and Health Guideline for Carbon Monoxide (PDF) (4 pp, 210 K, About PDF)* A passive monitor is currently under development. Moderately priced real-time measuring devices are also available. Some relatively high-cost infrared radiation adsorption and electrochemical instruments do exist.

Have a trained professional inspect, clean and tune-up central heating system (furnaces, flues and chimneys) annually.

Make certain that doors on all wood stoves fit tightly.

Choose properly sized wood stoves that are certified to meet EPA emission standards.

Install and use an exhaust fan vented to outdoors over gas stoves.

Use proper fuel in kerosene space heaters.

Consider purchasing a vented space heater when replacing an unvented one.

Additional ventilation can be used as a temporary measure when high levels of CO are expected for short periods of time. Vehicular use should be carefully managed adjacent to buildings and in vocational programs. It is most important to be sure combustion equipment is maintained and properly adjusted. Steps to Reduce Exposure to Carbon Monoxide Levels near properly adjusted gas stoves are often 5 to 15 ppm and those near poorly adjusted stoves may be 30 ppm or higher. At higher concentrations, CO exposure can be fatal.Īverage levels in homes without gas stoves vary from 0.5 to 5 parts per million (ppm). At moderate concentrations, angina, impaired vision, and reduced brain function may result. Acute effects are due to the formation of carboxyhemoglobin in the blood, which inhibits oxygen intake. Can cause flu-like symptoms that clear up after leaving home.

At higher concentrations, impaired vision and coordination headaches dizziness confusion nausea.

Health Effects Associated with Carbon Monoxide At low concentrations:

if the flue is improperly sized, blocked or disconnected.

worn or poorly adjusted and maintained combustion devices (e.g., boilers, furnaces).

incomplete oxidation during combustion in gas ranges, and unvented gas or kerosene heaters.

auto, truck, or bus exhaust from attached garages, nearby roads, or parking areas.automobile exhaust from attached garages.generators and other gasoline powered equipment.

back-drafting from furnaces, gas water heaters, wood stoves and fireplaces.

unvented kerosene and gas space heaters.

Sources of Carbon Monoxide Sources of CO include: The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure. Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home.

Steps to Reduce Exposure to Carbon MonoxideĬarbon monoxide is an odorless, colorless and toxic gas.

Deadly levels of carbon monoxide can quickly build up in these areas and can linger for hours, even after the generator has shut off.

#Carbon monoxide symptoms portable#

Never use a portable generator inside homes, garages, crawlspaces, sheds or similar areas.
