Frequently Asked Questions about variance requirements
and safe operation of lasers in the United States.
1. What power levels of laser require a variance?
Any laser with an output greater than 4.95mW, regardless of color
2. Is a variance a license?
Contrary to popular opinion a variance is not a license. A variance is
permission from the FDA to deviate from one or more of the requirements
of a standard when alternate steps are taken to assure safety.
3. What is the 3-meter rule?
The FDA criteria for manned laser shows is that NO laser radiation
Class IIIb and above be emitted below 3-meters above the highest
platform humans can stand on or 2.5-Meters horizontally and on the
sides of the projector or 2.5-Meters below the audience.
4. What agencies govern lasers?
The Food and Drug Administration (FDA)
Center for Devices of Radiological Health (CDRH)
For outdoor application of lasers: FDA, CDRH and the FAA
Note: Arizona, Texas, and New York have additional requirements if you intend to use a laser above 4.95 mW.
5. What are the rules regarding 4.95mW Lasers?
As a manufacturer we must state that the audience cannot be exposed to any outputs above Class I.
6. What are the classifications of the various outputs of lasers?
| Class I |
A class 1 laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE) cannot be exceeded. This class includes high-power lasers within an enclosure that prevents exposure to the radiation and that cannot be opened without shutting down the laser. For example, a continuous laser at 600 nm can emit up to 0.39 mW, but for shorter wavelengths, the maximum emission is lower because of the potential of those wavelengths to generate photochemical damage. The maximum emission is also related to the pulse duration in the case of pulsed lasers and the degree of spatial coherence. |
| Class IM |
A Class 1M laser is safe for all conditions of use except when passed through magnifying optics such as microscopes and telescopes. Class 1M lasers produce large-diameter beams, or beams that are divergent. The MPE for a Class 1M laser cannot normally be exceeded unless focusing or imaging optics are used to narrow the beam. If the beam is refocused, the hazard of Class 1M lasers may be increased and the product class may be changed. A laser can be classified as Class 1M if the total output power is below class 3B but the power that can pass through the pupil of the eye is within Class 1. |
| Class II |
Class 2 laser is safe because the blink reflex will limit the exposure to no more than 0.25 seconds. It only applies to visible-light lasers (400–700 nm). Class-2 lasers are limited to 1 mW continuous wave, or more if the emission time is less than 0.25 seconds or if the light is not spatially coherent. Intentional suppression of the blink reflex could lead to eye injury. Many laser pointers are class 2. |
| Class IIM |
A Class 2M laser is safe because of the blink reflex if not viewed through optical instruments. As with class 1M, this applies to laser beams with a large diameter or large divergence, for which the amount of light passing through the pupil cannot exceed the limits for class 2. |
| Class IIIR |
A Class 3R laser is considered safe if handled carefully, with restricted beam viewing. With a class 3R laser, the MPE can be exceeded, but with a low risk of injury. Visible continuous lasers in Class 3R are limited to 5 mW. For other wavelengths and for pulsed lasers, other limits apply. |
| Class IIIB |
A Class 3B laser is hazardous if the eye is exposed directly, but diffuse reflections such as from paper or other matte surfaces are not harmful. Continuous lasers in the wavelength range from 315 nm to far infrared are limited to 0.5 W. For pulsed lasers between 400 and 700 nm, the limit is 30 mJ. Other limits apply to other wavelengths and to ultrashort pulsed lasers. Protective eyewear is typically required where direct viewing of a class 3B laser beam may occur. Class-3B lasers must be equipped with a key switch and a safety interlock |
| Class V |
Class 4 lasers include all lasers with beam power greater than class 3B. In addition to posing significant eye hazards, with potentially devastating and permanent eye damage as a result of direct beam viewing, diffuse reflections are also harmful to the eyes within the distance called the Nominal Hazard Zone. Class 4 lasers are also able to cut or burn skin. In addition, these lasers may ignite combustible materials, and thus represent a fire risk, in some cases. Class 4 lasers must be equipped with a key switch and a safety interlock. |
