What must fire doors possess to meet safety standards?

To meet safety standards, fire doors must possess an Underwriters' Laboratories label. This certification indicates that the fire door has been tested and meets specific criteria for fire resistance and safety as established by industry standards. The label is a crucial indicator of the door's effectiveness in helping to prevent the spread of fire and smoke in a facility, thereby ensuring the safety of the residents and staff in a nursing home setting.

While emergency illumination and manual latching devices can enhance safety in a facility, they are not specific requirements for the fire doors themselves. Similarly, a painted surface finish may be relevant for aesthetic purposes but does not pertain to the fire safety standards that dictate the functionality of a fire door. Thus, the presence of an Underwriters' Laboratories label is essential for compliance with safety regulations concerning fire doors.
