ISO 7010 vs ANSI Z535
ISO 7010 provides registered safety signs. ANSI Z535 addresses safety colors, signs, symbols, labels, and related communication. They solve overlapping problems, but citing either one does not establish that a particular sign meets local requirements.
The distinction that matters
| Question | ISO 7010 | ANSI Z535 |
|---|---|---|
| What does it identify? | Registered safety signs with stable codes such as W012 and M004. | A family of standards addressing several aspects of safety communication. |
| What does the reader see? | A pictogram in a characteristic safety color and shape. | Depending on the application, a format combining signal words, messages, colors, and symbols. |
| What else must be checked? | Related design and application standards, local requirements, and site conditions. | The applicable Z535 part and edition, local requirements, and the particular product or facility. |
Recognize the ISO sign families
Warning triangles, prohibition circles, blue mandatory-action circles, green safe-condition signs, and red fire-equipment signs form the main families in this library. The visual guide shows examples and explains the message of each shape and color.
An ISO code identifies a particular sign. For example, W012 warns of electricity, while M004 communicates the use of eye protection. The code does not prescribe every detail of installation or workplace protection.
Check the actual jurisdiction
For US workplaces, OSHA 1910.145 contains specifications for accident prevention signs and tags and references particular editions of ANSI color standards. Other OSHA provisions can impose separate requirements for a specific hazard. A general statement that a sign is “ANSI compliant” is not a substitute for checking the provision that applies.
For Great Britain, HSE's guidance explains the Health and Safety (Safety Signs and Signals) Regulations. Elsewhere, consult the relevant national implementation and the authority responsible for the installation. An international symbol library does not remove those differences.
Use symbols with the information people need
Choose the correct pictogram and preserve its intended meaning. Then establish what wording, arrows, language, visibility, or other information the application requires. Do not assume that combining elements from two systems automatically satisfies both.
Two common mistakes are treating a generic electrical-warning symbol as a complete arc-flash label, or replacing required exit wording with a running-man pictogram without checking the applicable exit-sign rules.
A useful specification starts with questions
- What hazard or instruction must the sign communicate?
- Who will read it, and under what conditions?
- Which rule, standard part, edition, and local adoption apply?
- What are the required size, material, lighting, placement, and wording?
- Does the supplied artwork have the right identity and reuse permissions?
