OSHA and ANSI Compliant
OSHA and ANSI require that work safety signs indicate and define specific hazards that, without identification, may lead to injury or death. Select your sign with the header that indicates the degree of hazard in your application.
Safety Signage for all Situations
What is the difference between Caution, Warning and Danger?
DANGER safety signs are used to indicate that there is an immediate hazard with a high probability of death or severe injury.
WARNING safety signs indicate that there is a potentially hazardous situation, which, if not avoided, could result in serious injury or death.
CAUTION safety signs are used to alert people of a potential hazard. The hazard may result in minor or moderate injury, but not death.
Additional Safety Sign Headers
NOTICE safety signs indicate the need to provide general information to avoid confusion.
SAFETY, THINK, and EMERGENCY headings are used with information about health, housekeeping, first aid, medical equipment, and general safety.
What are OSHA and ANSI safety colors?
In addition to standardized wording, colors are assigned specific meanings in order to increase clarity of safety signs and labels. The following are the ANSI safety colors and where they should be used:
- Red: “Danger” signs, fire safety equipment, flammable liquids, emergency stop switches
- Orange: “Warning” signs, electrical hazards, work zones, exposed or moving machine parts
- Yellow: “Caution” signs, PPE instructions, common hazards, exposed edges, physical hazards
- Green: Safety signs (such as those pointing out medical equipment, first aid, emergency eyewash), general safety reminders
- Blue: “Notice” signs, maintenance, best practices

Frequently Asked Questions About Safety Signs
Can safety signs be customized?
Yes, as long as they follow OSHA’s guidelines for compliant presentation of information.
What colors fade more quickly than others?
Typically, red signs will fade faster than other colors. This is because they absorb more UV light than colors like blue and green, causing them to lose their vibrancy sooner. We minimize these effects by using UV-resistant inks in all of our signage.
What safety sign material lasts the longest?
All of the signs that we produce are made to be durable and last for many years. We can help you select which material will have the greatest longevity for your specific application.
