- PURPOSE
This procedure supports the safety requirements outlined in SA0500- Laser Safety. - DEFINITIONS
LASER– an acronym which stands for Light Amplification by Stimulated Emission of Radiation. Lasers produce an intense, highly directional beam of light. If directed, reflected, or focused on an object, the light can be absorbed which causes the temperature to increase on the surface or inside the object. This heat can cause alteration or deformation of the object.
Class 3B & Class 4 Lasers- Lasers that can present hazards to the eyes and skin if the beam is viewed directly or from reflections. The severity of these hazards depends on the wavelength and power output of the laser. These systems can also produce non-beam hazards such as fire, electrocution, and hazardous gases. - PROCEDURES
- Hazards from lasers can be minimized by following standard operating procedures, using appropriate laser safety eyewear, and adhering to properly posted warning signs.
- Safety standards for laser systems are based largely on guidance available through the US Department of Labor, Occupational Safety and Health Administration (OSHA) Standard #1926.54- Nonionizing Radiation
- Class 3B and 4 laser systems at UT Southern should be registered with Environmental Health & Safety at safety@utsouthern.edu.
- Facilities holding such lasers will be inspected every two years by a radiation safety officer.
- If a radiation safety officer is not employed by UT Southern, the Vice Chancellor of Finance & Administration, or their designee, will coordinate necessary inspections.
