Laser Safety Manual

16 Laser Safety Manual review by the LSO prior to acquisition or fabrication. These lasers shall also receive a final safety review via completion of a Laser Hazard Assessment by the laser system supervisor and the LSO prior to initial use. The final review will cover user qualifications, safe operation practices, electrical safety, area controls, and written SOPs. • Class 3B or Class 4 laser operators shall wear appropriately rated protective equipment (eyewear) as required. • The LSO shall be notified when Class 3B and Class 4 lasers or laser systems are purchased or constructed. • Class 3B and 4 lasers/laser systems require a Laser Use Authorization form . An authorization form will be generated upon the completion of a laser application, training, appropriate medical surveillance, and a Laser Hazard Assessment form . Standard Operating Procedures (SOPs) Process planning must begin with development of SOPs. This first step requires each investigator or laboratory work group to identify and evaluate all chemical, biological, radiological, and physical hazards associated with laser operations and describe safety precautions necessary to avoid employee exposures and injuries. SOPs must be specific to each laboratory operation. SOPs must be reviewed and approved by the PI or the laboratory supervisor. After approval, SOPs are then incorporated into or attached to written materials and methods. Laboratory personnel must be trained on the elements of the SOP before performing an experiment or operation. See the Standard Operating Procedure template . At minimum, SOPs must include the following: • Health and safety information for materials used – List and briefly describe the chemical, biological, radiological, and physical hazards associated with the operation of the laser or laser system. Identify available resources, such as safety data sheets (SDS) and operator’s manuals, and specify where they can be accessed. • Hazard control measures – Include containment devices, ventilation, specific personal protective equipment, and hygiene practices as recommended by the laser manufacturer or other authoritative guide. • Waste disposal practices – Establish procedures for the safe and timely removal of laboratory waste. Refer to “Waste and Recycling” in the Laboratory Safety Manual, as appropriate or develop written procedures if necessary.
