1 Safe Use of Lasers, the parent document in the Z136 series, provides information on how to classify lasers for safety, laser safety calculations and measurements, laser hazard control measures, and recommendations for Laser Safety Officers and Laser Safety Committees. ANSI Z136. This section highlights OSHA standards and documents related to laser hazards. For information related to the construction, see the Laser Hazards –. Consensus standards, such as American National Standards Institute (ANSI) Z136, provide users with control measures for laser hazards, as well as various tables helpful in calculating maximum permissible exposure (MPE) limits and accessible exposures limits (AELs). Thermal effects are the. 7 106 105 q. 04: Ionizing Radiation Producing Machines at NIST-B REQUIR iew process. This re-evaluation shall include classification to 124 identify appropriate controls as required in this suborder, but are not subject to 125 classification for compliance with 21 CFR 1040. 1 Standard for the Safe Use of Lasers and Z136. Average Power - The average power of a pulsed. If an excessive current flows in a laser diode, a large optical output is generated occur and the emitting facet may be damaged. Therefore, it specifies the largest current that must not be exceeded even for a moment.
