This could be dangerous if you have fuel-burning appliances.These appliances need fresh, outside air for proper combustion and ventilation.Exhaust fans, fireplaces, clothes dryers, and fuel-burning appliances draw air fromthe house to operate.

This may cause them to release poison-ous carbon monoxide gas into your home. It is very important to provide enoughfresh air to run all fuel-burning appliances.DANGERCarbon monoxide poisoning may lead to death!Carbon monoxide is a colorless, odorless gas.
