Section 121.008 - Special Requirements for Entertainment Laser Facilities
Current through Register 1531, September 27, 2024
Laser facilities utilizing a laser with a Class 3B or Class 4 ANSI laser classification in performances, or for demonstration or entertainment purposes, shall assure that:
(A) the laser meets all the design and labeling requirements of its class as established by ANSI Z136.1;
(B) laser radiation cannot exceed Class 1 limits, as established by ANSI Z136.1, in any areas where the audience is located;
(C) if devices, like mirror balls or flat mirrors, are used to reflect the beam, scanning safeguards or other measures are required to make sure that laser radiation above Class 1 limits, as established by ANSI Z136.1, will not accidentally go into the audience;
(D) performers cannot be exposed to radiation above Class 1 limits, as established by ANSI Z136.1, if they must view the laser beam in the course of a performance. When they do have to view the laser beam, performers cannot be exposed to radiation above Class 2 limits, as established by ANSI Z136.1;
(E) if the laser is not under the continuous control of an operator, laser radiation above Class 2 limits, as established by ANSI Z136.1, must be restricted so that it comes no closer than 20 feet above, or eight feet on the sides or below the floor where the audience would be;
(F) if the laser is under the continuos control of an operator, laser radiation above Class 2 limits, as established by ANSI Z136.1, can come no closer than ten feet above or eight feet on the sides or below the floor where the audience would be;
(G) appropriate controls must be taken to make sure that unauthorized persons cannot interfere with the safe operation of the laser. A person must be designated as the laser safety officer who will be responsible for shutting down the laser should any unsafe conditions occur;
(H) a variance has been granted by the United States Food and Drug Administration to the requirements of 21 CFR Ch. I, Subchapter J, Part 1040; and,
(I) a copy must be submitted to the Radiation Control Program of any notification the registrant is required to submit to the Federal Aviation Administration, under its regulations.
