Burning firewood creates many byproducts, including smoke, water vapor, various gases, hydrocarbons and tar. Over time, these materials can accumulate in your fireplace and increase your risk of danger, including chimney fire and carbon monoxide poisoning. Always keep your fireplace chimney well ventilated and have it cleaned. The U.S. Consumer Product Safety Commission, the U.S. Environmental Protection Agency, the National Fire Protection Association, and the American Lung Association recommend annual maintenance and inspection of your home’s heating systems, fireplaces included.

If at all possible, keep the lumber pile sheltered from precipitation, while still exposed to airflow and sunlight. Tree bark is a natural moisture barrier, so arrange the lumber to maximize evaporation. If a lot of rain is expected, arrange the wood pieces bark side up. If there is a lot of ground moisture from snow or standing water, arrange wood pieces bark side down.
