Machine Hazard signs tell you about dangers with a machine. These dangers can be electricity, high temperatures, strong pressure, getting caught, or chemicals. These signs are different from warning signs because they are about a specific machine.

General warning signs give you safety rules for a place. Machine Hazard signs are applied directly to machines to tell exactly what to be careful about with that machine.

These are OSHA standards that apply.

* OSHA 29 CFR 1910.145 is about signs and tags that prevent accidents.

* OSHA 29 CFR 1910.212 applies to machine guarding.

* OSHA 29 CFR 1910.147 applies where machines pose hazardous energy risks during servicing.

These signs should be on the machine close to the danger. They should be on control panels and access covers and at a level where the operator can see them easily. They should be easily visible when you approach the machine.

These signs are made to handle industrial surfaces. If the surface is extremely hot, you need to check the product details and consider whether a different mounting approach is needed.

The sign should tell you about the actual danger. There are Machine Hazard sign messages available so you can find one that tells you about the risk on your machine.

You do not always need a sign. Some machines have one clear primary hazard. Others have several, in which case using multiple targeted signs placed at the relevant points on the machine is better.

Hazard signs like Keep Hands signs come in different sizes. Some common sizes are 3.5" x 5", 5" x 7", 7" x 10", and 10" x 14". These sizes are good because they are big enough to grab people's attention. Small enough to fit in the space available. Keep Hands signs need to be the size so that workers can see them clearly.
