The invisible risk
Chimney liners should be checked to prevent carbon-monoxide poisoning by Derek Neary
NNSL (Feb 06/98) - Yellowknife firefighters have been receiving calls about ice buildup around chimneys from oil-heated homes.
In response, they are delivering leaflets to residences where this appears to be a problem.
The danger lies in the collapse of the chimney's inner liner from the weight of the ice. The situation could force fumes into the home and lead to carbon-monoxide poisoning.
"It has sent people to the hospital in the past," Lowing pointed out.
Carbon monoxide is a colorless, odorless gas that can kill if a person is overcome by fumes.
There is also a potential hazard when the inner liner begins to corrode.
Lowing recommended that homeowners take a good look at their chimneys. The homeowner can remove ice buildup himself or herself, or a general contractor can be called.
A liner in good condition should have a smoothly rounded surface from top to bottom. There should be no bulging or separation.
Signs of carbon monoxide poisoning include: nausea, vomiting, headache, drowsiness, confusion, stinging eyes and tightness of the forehead. |
