Every required exit route must be visible and clearly marked. <b data-path-to-node=\"12\" data-index-in-node=\"101\">The Requirement:<\/b> An &#8220;EXIT&#8221; sign must be placed at every exit door. The letters must be at least <b data-path-to-node=\"12\" data-index-in-node=\"197\">6 inches high<\/b> with a stroke width of 0.75 inches.

You must mark these doors with a sign reading <b data-path-to-node=\"14\" data-index-in-node=\"307\">&#8220;Not an Exit&#8221;<\/b> or identify their actual use, such as <b data-path-to-node=\"14\" data-index-in-node=\"359\">&#8220;Closet,&#8221; &#8220;Electrical Room,&#8221;<\/b> or <b data-path-to-node=\"14\" data-index-in-node=\"391\">&#8220;Restroom.&#8221;<a href=\"https:\/\/www.mydoorsign.com/blog\/wp-content\/uploads\/2026\/01\/not-an-exit-entrance-sign-s-1275g.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4697 aligncenter\" src=\"https:\/\/www.mydoorsign.com/blog\/wp-content\/uploads\/2026\/01\/not-an-exit-entrance-sign-s-1275g.png\" alt=\"\" width=\"200\" height=\"145\" \/><\/a><\/b><\/p>\n<h3 data-path-to-node=\"15\">3. <a href=\"https:\/\/www.mydoorsign.com\/search\/fire_warning_sign\">Fire Door Warnings<\/a><\/h3>\n<p data-path-to-node=\"16\">Fire doors are heavy, self-closing barriers designed to slow the spread of smoke and flames.

Are &#8220;Not an Exit&#8221; signs mandatory?<\/b><\/p>\n<p data-path-to-node=\"26\"><b data-path-to-node=\"26\" data-index-in-node=\"35\">A. Yes, if the door can be mistaken for an exit.<\/b> OSHA requires that any door that could likely be confused for an exit route must be marked &#8220;Not an Exit&#8221; or identified by its actual function (e.g., &#8220;Storeroom&#8221; or &#8220;Office&#8221;). This prevents confusion during a rapid evacuation.<\/p>\n<p data-path-to-node=\"27\"><b data-path-to-node=\"27\" data-index-in-node=\"0\">2. What color should Exit signs be?<\/b><\/p>\n<p data-path-to-node=\"27\"><b data-path-to-node=\"27\" data-index-in-node=\"33\">A. Red or Green are both acceptable.<\/b> OSHA does not specify a color, but NFPA and local fire codes usually dictate whether Red or Green is required in your specific municipality. Red is the most common color in the United States because of its association with fire hazards, while Green is the international standard for &#8220;Go&#8221; and safety.<\/p>\n<p data-path-to-node=\"28\"><b data-path-to-node=\"28\" data-index-in-node=\"0\">3. How often do I need to check my exit signs?<\/b><\/p>\n<p data-path-to-node=\"28\"><b data-path-to-node=\"28\" data-index-in-node=\"44\">A. Monthly and Annually.<\/b> If you have battery-powered illuminated exit signs, fire codes typically require a quick 30-second functional test every month and a full 90-minute battery drain test once a year to ensure the lights will stay on during a prolonged power outage.<\/p>\n<p data-path-to-node=\"29\"><b data-path-to-node=\"29\" data-index-in-node=\"0\">4. Can I prop open a fire door?<\/b><\/p>\n<p data-path-to-node=\"29\"><b data-path-to-node=\"29\" data-index-in-node=\"29\">A. Generally, no.<\/b> Fire doors must remain closed and latched to prevent the spread of fire. The only exception is if the door is equipped with an automatic magnetic hold-open device that is tied to the fire alarm system. In this case, the door will automatically release and close when the alarm sounds. Signs for these doors must read &#8220;Fire Door &#8211; Do Not Block.&#8221;<\/p>\n<\/blockquote>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>In a commercial facility, a door is never just a door.
