Final answer:
During the inspection of a fireplace, inspectors inspects the presence and adequacy of non-combustible hearth extension.
Step-by-step explanation:
During the inspection of a fireplace, inspectors inspect the presence and adequacy of the non-combustible hearth extension. The non-combustible hearth extension is an important safety feature that helps to prevent fire hazards.
It is typically made of materials such as stone, tile, or concrete that can withstand high temperatures.
Inspectors check if the hearth extension extends at least 16 inches in front of the fireplace opening and 8 inches beyond each side of the opening. This ensures that there is enough space to contain any embers or sparks that may escape from the fire and prevent them from reaching combustible materials.
For example, if the hearth extension is not present or is inadequate, it could pose a risk of fire spreading to nearby structures. Inspectors also consider the height of the hearth extension to ensure it is sufficient to provide protection from heat radiating from the fire.
