Although it is not uncommon to see signage attached to a fire door – sometimes numerous signs – there are limitations regarding the size of the sign, the method of attachment to the door, and restrictions regarding the type of glazing that a sign may be attached to.  During a fire door inspection, one of the inspection criteria is to check the signage for compliance with these requirements.

The codes and standards require some signage used on doors to have specific wording – for example, “PUSH UNTIL ALARM SOUNDS. DOOR CAN BE OPENED IN 15 SECONDS.” in locations where delayed egress locks are used.  Signage must also comply with the visual character requirements of the accessibility standards, to ensure that the signs can be read by building occupants with varying levels of vision.  Although the character size, stroke width, spacing, and contrast are often addressed by the manufacturer of the signage, it’s important to be aware of the mounting height requirements so the sign is installed properly.
