What is backdrafting in a kitchen context?

Backdrafting refers to the situation where combustion by-products from gas appliances, such as stoves or ovens, are unintentionally drawn back into the living space rather than being vented outside. This phenomenon typically occurs when there is inadequate ventilation or when exhaust fans and other appliances create negative pressure in the home. As a result, harmful gases, such as carbon monoxide and nitrogen dioxide, can re-enter the kitchen or other areas of the house, posing significant health risks to occupants.

Understanding backdrafting is essential for kitchen design and safety, as proper ventilation systems must be implemented to prevent this issue. Effective solutions may include the installation of range hoods that efficiently draw air out or balancing air pressure with an adequate supply of fresh air to the kitchen.
