Frequently Asked Questions

Q. Are these laser warning signs compliant with official standards?

Yes, our laser warning signs are designed to comply with official standards, primarily the ANSI Z136.1 standard for the Safe Use of Lasers, which is the national consensus standard referenced by OSHA.

Q. What information must be included on a laser warning sign?

According to ANSI standards, a proper laser warning sign must include the signal word (Danger, Warning, Caution), the laser hazard symbol, the laser's class, and information about the laser's wavelength, maximum power, and pulse duration.

Q. What is the difference between "Danger," "Warning," and "Caution" headers on laser signs?

The header indicates the level of risk, as defined by ANSI standards. "Danger" is used for Class 3B and Class 4 lasers, which can cause severe and permanent eye injury. "Warning" is used for Class 3R lasers, and "Caution" is used for Class 2 and 2M lasers.

Q. Where should I place laser warning signs for maximum effectiveness?

For maximum effectiveness, laser warning signs should be conspicuously posted at all entrances to areas where lasers are in use, as well as on equipment, to ensure personnel are aware of the hazard before exposure.

Q. What do the different laser classes (e.g., Class 2, 3B, 4) mean?

Laser classes categorize lasers by their potential to cause injury, from the safest (Class 1) to the most hazardous. For example, a laser is a high-power laser that can cause severe eye and skin damage and also presents a fire hazard.
