LX Projector Safety

Back to Main

First and foremost, the LX projector is designed for safety!

At Laserwurx, the safety of the laser system and its operation is the first priority.

The Center for Devices and Radiological Health (CDRH) regulates all laser equipment and performances in the United States. The Laserwurx LX Projector has been approved for use by the CDRH in the USA. The result of this approval is the granting of a "variance" for the use of the LX projector in performance and other venues.

Safety is designed into the LXC in a number of ways

The LX projector utilizes the highest quality, tour proven components for trouble free use.
The LX projector’s optical path is completely sealed; there are no internal adjustments or maintenance required. The optics remain clean and perfectly aligned.
The LX projector incorporates a series of safety devices to maintain compliance with federal regulations and public safety.
All fixtures incorporate redundant safety circuits as well as independent control systems to ensure safety in any error condition.
The LX projector and its safety procedures are approved by Center for Devices and Radiological Health (CDRH) for use in performance events

About the CDRH Variance

The CDRH, ANSI and other regulations control the use of lasers in entertainment.

A CDRH variance is issued to companies upon successful proof that all aspects of laser safety and compliance with Code of Federal Regulations Title 21 parts1040.0 and 1040.1 are demonstrated.

This variance allows a laser show company to legally produce laser shows and effects in public venues. Any laser product that contains a laser with a maximum output power over 5 mw is required to have a variance and meet special reporting and operational requirements.

Classes of Lasers

Class I
These lasers cannot emit laser radiation at known hazard levels.
Class I.a
This is a special designation that applies only to lasers that are "not intended for viewing," such as a supermarket laser scanner. The upper power limit of Class I.a is 4.0 mW.
Class II
These are low-power visible lasers that emit above Class I levels but at a radiant power not above 1 mW. The concept is that the human aversion reaction to bright light will protect a person.
Class IIIa
These are intermediate-power lasers (cw: 1-5 mW), which are hazardous only for intrabeam viewing. Most pen-like pointing lasers are in this class.
Class IIIb
These are moderate-power lasers. (cw: 6-499 mW), which are hazardous for intrabeam viewing and prolonged exposure to skin.
Class IV
These are high-power lasers (cw: >500 mW, pulsed: 10 J/cm2 or the diffuse reflection limit), which are hazardous to view under most conditions.

Significant controls are required for Class IV laser products

The LX projector is a Class IV laser product which is why it is very effective in the creation of visual laser effects.

The LX projector has been designed in such a way that eliminates the headaches associated with traditional laser shows.

There are three main rules when using the LX projector

All laser emission must be at least 3 meters above any surface that people are permitted to stand and 2.5 meters laterally from any place where people are permitted to stand. No laser emission is allowed to hit the audience.
The operator must have complete unobstructed view of all laser emission.
The operator / LSO is the only person allowed to operate the laser system.

Other aspects of laser safety

There are many other aspects to laser safety that are defined in the LSO training course.
