Laser Pointer Safety and Site Requirements

Introduction

This Alert provides guidelines for the safe use of laser pointers at the Clinton site. The guidelines areconsistent with the ANSI Z136.1 laser classification system and addresse recent instances of on-site use of high power laser pointers which are potentially harmful to eyes.

Background

All laserpointers used on site, must have a classification of 1, 2, or 3R and in the older classification system I, II, IIa, or IIIa. The laser classification can be determined by examining a sticker affixed to alllaser devices:

The laser classifications Classes 1M and 2M, 3B, 4 and in the older classification IIIb and IV are NOT permitted for use as laser pointers. The M designation indicates potential eyedamage if viewed with certain optical aids. Lasers Class 3B, IIIb, 4 and IV produce hazardous power levels and are required by OSHA to be administered under a Laser Safety Program that includescontrols, PPE, tracking and training.

Important Note

Several laser pointers on site have been found to have power levels that exceed the levels specified on their labels. Contact the Laser SafetyOfficer (Shawn Dougal) if you suspect the power level is too high and/or would like to have the power level of your laser pointer measured.

Guidelines

Always verify that the laser pointer you are using is Class 1, 2, 3R or Class I, II, IIa or IIIa. Do not use a laser pointer with anoutput that seems too bright or causes you to squint at the screen. Some inexpensive laser pointers have power levels that exceed their rated output. Never stare into nor point a laser pointer at anyperson, regardless of the class. Only energize the laser while pointing at the screen; never “sweep the room” with an energized laser pointer or direct it at the audience. Be aware of any reflective...
