Frequently Asked Questions

What does ANSI mean when it comes to safety signs?

ANSI stands for American National Standards Institute. The standard that really matters here is ANSI Z535. This standard is like a rule book that tells us how to make safety signs. It says what colors to use, what words to use when something's dangerous how to lay out the sign and how to use symbols on the sign. This is, like a language that we all use to stay safe at our jobs.

Why does it matter whether a sign follows ANSI standards?

It is really important that safety signs look the same. When signs look the same workers can read them quickly. They are less likely to miss a warning or get it wrong when things are happening fast.

Where are ANSI safety signs required or recommended?

ANSI safety signs are used in a lot of places like factories, warehouses, construction sites, electrical rooms, laboratories and loading docks. Anywhere that people need to know about safety ANSI safety signs are used. Many industries use ANSI Z535 in their safety plans. When they are checked by OSHA.

What are the signal words used in ANSI safety signs?

The signal words are DANGER in red; this means something can hurt you badly or even kill you. A WARNING in orange means something can hurt you badly. CAUTION in yellow means something can hurt you a little or moderately. NOTICE in blue is for information that's important but not about safety.

How are ANSI signs different from OSHA-style signs?

OSHA 29 CFR 1910.145 sets the federal regulatory requirement for safety signs in general industry. ANSI Z535 is the voluntary standard that most modern sign designs follow. Many signs are designed to satisfy both, and using ANSI-formatted signs is widely accepted as a compliant approach.

Can these be used outdoors?

Yes, they can. The vinyl is waterproof, so it can withstand the sun, rain, and different temperatures without fading or coming apart.

What size options are available?

These signs come in different sizes. We need sizes so the signs are easy to see and read. The signs need to be big enough to get people's attention. Small enough to fit in the space we have. ANSI safety signs come in sizes to make sure everyone can see them clearly.
