Materials and Sizes for Workplace Safety Signage
Material Selection & Size Considerations
When it comes to the size of your sign, you will want to focus on text visibility for optimized legibility. According to OSHA, signal texts should be readable within 5 feet, and Exit sign letters should not be smaller than 6 inches high. ANSI requires that the font size relate to the viewing distance. Both the sign and text must be large enough for the reader to understand and respond to avoid potential danger.
Both OSHA and ANSI offer tables on their website to help you make a specific and educated decision.

FAQs
- You need safety signs for many reasons. One reason is that in many spaces, it is a legal requirement. A second reason is that if you don’t have safety signs, it can be a liability. And a third reason is that it makes your space safer for you, your workers, and the public.
- According to the Occupational Safety & Health Administration (OSHA), most workplaces, regardless of industry, must have the following three safety signs throughout the workspace: Danger, Warning, and Safety Instruction signs.
- Yes. When it comes to safety signs, there are specific OSHA requirements that also apply to construction safety signs. OSHA requires that all safety signs use specific colors, words, symbols, and have rounded corners. They should be placed in areas that are visible to everyone and readable from at least five feet away.
Signal words must be clear and simple enough to understand (Danger, Warning, and Caution). No sign can contain pictograms only. If a pictogram is included in a sign, it must be placed before the signal word. For colors, danger signs should only have red, black, and white colors. Safety instruction signs should have a white background with black text and green panels with white text. Caution signs should have a yellow background with black letters, and black panels with yellow letters. The American National Standards Institute (ANSI) consists of a series of standards for safety signage, including:
- Headers and words (Safety, Caution, Danger, etc.).
- Symbols to communicate specific dangers, prohibitions, and mandatory alerts.
- Text specifying the type of alert.
- Colors that specify the level of danger: Red (danger), orange (warning), yellow (caution), blue (notice), and green (safety instructions).
- At Square Signs, we offer several ready-made safety sign templates. These include but are not limited to: Road Work Ahead Signs, Caution Signs, Eye Protection Safety Signs, Warning Signs, No Smoking Signs, Danger Signs, and more.
- Effective warehouse safety signs are placed in eye-level spacing, are visible, and use universally recognized symbols. These signs include hazard warnings, prohibition signs, emergency/first aid signs, instructions, and fire safety signs.
- Metal signs like aluminum and dibond are rust and bend-resistant. PVC and styrene are waterproof. These features allow them to last for years.
- You should place your safety signs on walls near machinery, emergency routes, high traffic areas, and any zone that contains biohazard materials.
- Yes, because caution and warning signs can influence behaviors that lead to best practices.
- Yes. Square Signs offers a free design tool in which you can make your sign unique. However, you will still need to follow OSHA safety sign color requirements.
- To choose the right material for your workplace safety signs, you will want to know where you are going to place them and what kind of environment they will be in. Safety signs are typically made from aluminum, dibond, PVC, styrene, and paper.
- The Occupational Safety & Health Administration (OSHA) is a federal agency that monitors and enforces workplace safety. The American National Standards Institute (ANSI) is a private, nonprofit organization that oversees and coordinates the standards set forth by the U.S. federal government.
Since OSHA has adopted the practices developed by ANSI, the differences might seem confusing at first. The biggest difference is in the design. ANSI headers are color-coded, contain symbols, and upper/lower case letters that are left-justified.
