While signs outside of work may struggle to stand out amongst the clutter and confusion, a workplace should have streamlined, cohesive approach to how messages are posted, reserving safety signage for the most important safety messages.

Here is a rundown of the top 10 most important safety signs every facility should have.

  1. The Exit Sign

Any time you enter a facility, the first thing you should look for is how to exit that very same facility. In any building that is in compliance with OSHA and NFPA regulations, there should be clearly marked exits and unobstructed routes to get to them. You never know when an emergency may occur or just the urge to get out of there!

  1. The Authorized Personnel Only Sign

Everyone has their nosy moments, wanting to see what goes on behind the scenes and out of view; however at times that can go against your best interests when it comes to safety.

An area where an authorized personnel sign could be needed could include an HR department where there are private documents or any area where there is lab testing or hazardous chemicals.

  1. The PPE Sign

Posting this sign with help to remind an employee about the machine that they are working around however when performing maintenance on a machine the proper lockout tag out procedures should always be followed.

  1. The Forklift Safety Sign

If there are known areas within your facility where tripping incidents or near misses consistently occur consider posting a caution sign.
