In which locations are fireplaces and solid-fuel burning appliances prohibited?

Fireplaces and solid-fuel burning appliances are prohibited in hazardous locations because these areas present increased risks of fire or combustion-related incidents. Hazardous locations are defined in building codes as places where flammable or explosive materials may be present, which can significantly heighten the dangers associated with open flames and solid fuels. For instance, these areas may include locations near volatile chemicals, dusts, or other materials that can ignite easily.

In contrast, while residential areas, outdoor settings, and agricultural buildings all have guidelines for the installation and usage of such appliances, they are not outright prohibited. Instead, regulations may require specific types of construction, proper ventilation, and adherence to safety standards to mitigate risks. The prohibition in hazardous areas is a precautionary measure to ensure safety and reduce the likelihood of accidents in environments where the presence of flammable materials is a major concern.
