How much clearance is required for closet fixtures where combustible materials may be stored?

The required clearance for closet fixtures where combustible materials may be stored is 18 inches. This clearance is essential for fire safety reasons, as it helps to prevent ignition of materials that could be located nearby. Keeping fixtures such as lights 18 inches away from any combustible materials significantly reduces the risk of a fire starting due to heat generated by the fixtures.

By adhering to this standard, you ensure that there is adequate space for heat to dissipate, which is particularly important in areas where flammable items might be stored, such as clothing or paper products. It also complies with many electrical codes and safety guidelines that are designed to protect both people and property.
