What is the recommended action if a fire rated door has glass?

When dealing with fire rated doors that incorporate glass, the recommended action is to ensure that the glass is at the allowable size limit as specified by building codes and fire safety regulations. Fire rated doors are designed to provide a barrier against the passage of fire and smoke, and when glass is added, it is crucial to assess not only the type of glass used but also its dimensions and positioning.

Using glass in a fire rated door can compromise its fire resistance if the glass exceeds the specified size limits. Therefore, adhering to these limits ensures that the door maintains its intended fire-resistant properties while allowing some visibility or light into the space. Applicable standards will dictate how much glass can be included based on the fire rating of the door.

This approach balances safety with practical needs without rendering the fire door ineffective. The other options—such as replacing the door with a non-fire rated door or increasing the amount of glass—could potentially violate fire safety codes, thereby increasing safety risks. Avoiding the use of any glass may also limit design options unnecessarily while not addressing the code-compliant use of glass in fire rated assemblies.
