SEC-011: Laser Safety
Academic Division and the College at Wise.
Lasers are commonly used in the course of research and education, and radiation emitted from lasers can present a physical hazard to individuals and building structures. This policy is to protect faculty, staff, students, and University buildings from exposure to hazardous levels of laser radiation and to other hazards that can be generated by laser devices.
- Class 3B Laser:A laser system that may be hazardous under direct and specular reflection viewing conditions, but diffuse reflection is usually not a hazard. Normally not a fire hazard. Specific controls are required for Class 3B lasers.
- Class 4 Laser:A laser system that is a hazard to the eye or skin from the direct beam and sometimes from a diffuse reflection and can also be a fire hazard. Significant controls are required.
Class 3B and Class 4 lasers must be registered with the University Laser Safety Officer and approved prior to operation. Faculty, staff, and students must comply with all applicable federal, state, and local regulations which apply to the safe use and disposal of Class 3B and Class 4 lasers. Additionally, consensus standards from the American National Standards Institute (ANSI)1 are to be employed as appropriate to protect personnel and the environment from potentially adverse exposures to Class 3B and Class 4 lasers.
1 ANSI (American National Standards Institute) Standard Safe Use of Lasers, Z136.1; Safe Use of Lasers in Educational Institutions, Z136.5; Safe Use of Lasers in Research, Development, or Testing, Z136.8.
