CARBON MONOXIDE - POISONOUS GAS
DANGER: CARBON MONOXIDE POISONING MAY LEAD TO DEATH!
Space heaters exhaust contains carbon monoxide - a poisonous gas that can kill you. You CAN NOT smell or see this gas.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, and/or nausea. If you have these signs, the space heater may not be working properly. Get fresh air at once! Have space heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, persons with heart or lung disease or anemia, those under the influence of alcohol, and those at high altitudes.
Never use a space heater in enclosed or partially-enclosed spaces without proper ventilation. Use only in well-vented areas. Before using space heater, provide at least a three-square-foot (2800 square cm) opening of fresh, outside air for each 100,000 Btu / Hr (30 kw) of rating. Space heaters can produce high levels of carbon mono
xide very quickly. When you use a space heater, remember that you cannot smell or see carbon monoxide. Even if you can’t smell exhaust fumes, you may still be exposed to carbon monoxide.
If you start to feel sick, dizzy, or weak while using a space heater, get to fresh air RIGHT AWAY. DO NOT DELAY. The carbon monoxide from space heaters can rapidly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immediately. Inform medical staff
that carbon monoxide poisoning is suspected. If you experienced symptoms while indoors, have someone call the fire department to determine when it is safe to re-enter the building.
NEVER operate the space heater in an explosive atmosphere, near combustible materials or where ventilation is not sufficient to carry away exhaust fumes. Exhaust fumes can cause serious injury or death.
NEVER run space heaters inside homes, garages, sheds, or other semi­enclosed spaces without proper ventilation. These spaces can trap poisonous gases EVEN IF you run a fan or open doors and windows. Use only in well­vented areas. Before using space heater, provide at least a three-square-foot (2800 square cm) opening of fresh, outside air for each 100,000 Btu / Hr (30 kw) of rating.
If you start to feel sick, dizzy, or weak while using the space heater, shut if off and get fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with battery back-up in your home, according to the manufacturer’s installation instructions. The carbon monoxide alarms should be certified to the requirements of the la (UL 2034, IAS 6-96, or CSA 6.19.01).
test safety standards for carbon monoxide alarms.
Test your carbon monoxide alarm frequently and replace dead batteries.
