When working with Class 4 lasers, be sure to use the buddy system. To avoid injuries, make sure that unauthorized people are not present and are not able to enter the lab at any time an alignment is being conducted.īuddy System. If an alignment procedure is recommended or required, use the following as a guide for items that may need to be considered in your particular application.Īccess.

Most laser accidents in research settings occur during the alignment process. Rules for building and facility workers as necessary

Examples for control measures are shutting down the main laser and using an alignment laser, reducing the power/energy of the laser, use of beam dumps for the primary beam, etc. Special attention should be given to control measures that can reduce the potential for exposure. List the steps used to perform beam alignment on the laser or laser system. Step-by-step protocol on laser system operation Personal Protective Equipment preparation The procedures shall be written for the benefit of the laser user who must read and understand them to perform the operation safely. List the sequential events that describe the complete operation, including when to implement the hazard control measures. Identify and analyze the specific hazards associated with the laser operationĭescribe the training requirements for the laser users and incidental personnel. Pulse length, repetition rate, beam diameter and divergence, etc.)īriefly describe the purpose of the operation. Specifications (continuous (CW), pulsed, Q-switched, wavelength, power/energy, Laser type, manufacturer, model, serial number, classification, and technical The SOP should include all lasers in a given laser system including alignment and pumping lasers. The information should be used as a guide to allow you to develop a SOP that is specific to your laser system. These guidelines are intended to aid PIs and individual laser users in preparing standard operating procedures (SOPs) for lasers and laser systems.
