QUESTIONS AND ANSWERS	Yes	No
1. Have you had the fireplace draft and the drafts of other fuel-burning appliances checked by an expert within the past year?
Answer: Yes, A yearly checkup of all fuel-burning venting systems in the home is desirable.
2. Have all gas appliances been checked annually for proper operation?
Answer: Yes, A yearly checkup of all combustion appliances is suggested. In many cases, upon request, the gas company will provide this service.
3. Are all combustion appliances properly vented?
Answer: Yes, all gas appliances must have adequate ventilation so that CO will not accumulate.
4. Has your chimney vent been checked for defects within the past year?
Answer: Yes, chimney vents often become blocked by debris causing a buildup of CO. They should be checked annually.
5. Have you patched any vent pipe with tape, gum, or other substances?
Answer: No, often a makeshift patch can lead to an accumulation of CO, and therefore should be avoided.
6. Are all horizontal vent pipes to fuel appliances perfectly level?
Answer: No, in-room vent pipes should be on a slight incline as they go toward the exterior. This will reduce leaking of toxic gases in case the joints or pipes are improperly fitted.
7. Do you use your gas range or oven for heating?
Answer: No, using a gas range for heating can result in the accumulation of CO.
8. Does the cooling unit of your gas refrigerator give off an odor?
Answer: No, an unusual odor from a gas refrigerator often is the result of defects within the cooling unit. Odorless CO also may be given off.
9. Have you ever used a charcoal grill, such as a barbecue grill for cooking within your home, cabin or camper other than in a vented fireplace?
Answer: No, the use of barbecue grills indoors will quickly result in dangerous levels of CO.
10. Have you ever brought burning charcoal into your home, cabin or camper for heating purposes?
Answer: No, burning charcoal - whether black, red, gray, or white - gives off CO.
11. Do you consider portable flameless chemical heaters (catalytic) safe for use in your cabin, camper or home?
Answer: No, Although catalytic heaters produce heat without flame, combustion is occurring that can cause the production of CO.
12. Have you ever used a portable gas camp stove in your home, cabin or camper for heating purposes?
Answer: No, using a gas camp stove for heating the home, cabin or camper can result in the accumulation of CO.
