Most jurisdictions have stringent building codes that mandate the inclusion of fire-rated access doors in specific locations within a building. These codes ensure that construction practices prioritize safety and adherence to fire-resistance ratings. Building professionals must select access doors that meet or exceed the required fire ratings and must ensure proper installation to maintain these ratings.

Fire-rated access panels are unique construction features designed to provide convenient access to concealed areas, such as plumbing, electrical, and HVAC systems, while also offering fire-resistance capabilities. Constructed from materials that can withstand high temperatures, these panels are tested and rated according to specific fire-resistance standards, usually segmented by time—such as 1-hour or 2-hour ratings—indicating the duration for which they can contain heat and flames during a fire incident.
