Laser classification and entry controls are summarized below.Ĭlass 1 denotes exempt lasers or laser systems that cannot, under normal operating conditions, produce a hazard. Only lasers fabricated on-site would require classification by the investigator, which requires approval of the radiation safety officer. In addition to meeting the general requirements of this chapter, lasers must meet specific requirements based on laser class. Lasers are classified according to the definitions of Section 3.3 of ANSI Z136.1. Classification and labeling of commercially purchased lasers is the responsibility of the manufacturer. *If invisible to the eye, and if a cw laser, with visible beams > 15mW of power. The following is a summary of requirements for laser use.

ANSI Z136.1 is available from the lab manager. Further, all operations involving the use of high-power lasers shall be planned and executed using the recommendations of the American National Standards Institute Z136.1 - 2000, 'Standard for the Safe Use of Lasers.' Many of those recommendations are incorporated into this document. All operations or research involving the use of lasers must be conducted in such a manner as to ensure that personnel exposure to laser radiation is below the maximum levels specified in 105 CMR 121.600.

This document delineates the requirements for registration and safe use of high power lasers and laser systems. This section describes requirements for personnel protection from laser radiation and other associated hazards. These requirements are designed to comply with the Massachusetts Department of Public Health (DPH) Code 105 CMR 121.000, Rules and Regulations Relative to the Use of Laser Devices or Equipment to Control the Hazards of Laser Rays and Beams (pdf) It is now widely accepted that the human eye is almost always more vulnerable to injury than human skin.At this time, radioactive materials are not to be used in the Cole Science Center. Research relating to injury thresholds of the eye and skin has been carried out in order to understand the biological hazards of laser radiation. The human body is vulnerable to the output of certain lasers, and under certain circumstances, exposure can result in damage to the eye and skin. The most common cause of laser-induced tissue damage is thermal in nature, where the tissue proteins are denatured due to the temperature rise following absorption of laser energy. The laser produces an intense, highly directional beam of light. LASER is an acronym which stands for Light Amplification by Stimulated Emission of Radiation. Focuses on some of the hazards and controls found in the hospital setting and describes standard requirements as well as recommended safe work practices for employee safety and health.

The Alliance provides LIA's members and others, including small businesses with information, guidance, and access to training resources that will help them protect employees' health and safety, particularly in reducing and preventing exposure to laser beam and non-beam hazards in industrial and medical workplaces.
