OHA release - Oregon Health Authority urges caution with wood stoves to prevent carbon monoxide poisoning during winter months.  As it gets colder and Oregonians rely more on wood stoves, space heaters and other heating sources to stay warm, Oregon Health Authority (OHA) reminds you to take steps to prevent carbon monoxide poisoning.   Carbon monoxide is a colorless, odorless gas and is produced when fuel is burned. In winter, carbon monoxide risks are higher because we close our windows and doors and use heating appliances.  Exposure can cause headaches, dizziness, nausea, confusion, loss of consciousness and can cause death if not treated quickly.   Wood stoves that are not installed, cleaned or vented correctly can cause carbon monoxide problems in the winter.  OHA asks you to:   Have wood stoves, chimneys and vents inspected and cleaned every year by certified professionals.  Make sure wood-burning devices are properly vented to the outside.  Never use outdoor heating or equipment indoors. This includes camp stoves, charcoal grills and generators.  More safety tips:  Install carbon monoxide alarms that are battery-powered or have battery back-up  on every level of your home.  Test alarms every month and change the batteries twice a year.  Never run vehicles, generators or gas-powered tools in enclosed or partly enclosed spaces.   If a carbon monoxide alarm sounds or if you feel symptoms like headache, dizziness, nausea, or confusion:  Go outside to breathe fresh air right away.  Call 911.
