Ariz. Admin. Code § 9-7-1433

Current through Register Vol. 30, No. 45, November 8, 2024

Section R9-7-1433 - Laser Use Areas that are Controlled

A. A registrant shall establish a controlled area for a laser if it is possible for a person to be exposed to laser radiation from a Class 3b laser, except a Class 3b laser of less than 5 milliwatts visible peak power, or a Class 4 laser that exceeds the applicable MPE or AEL in R9-7-1426.

B. A registrant shall ensure that a controlled area associated with a Class 3b laser is:

1. The responsibility of a LSO;

2. Posted in accordance with this Article; and

3. Access controlled by the LSO or a trained, designated representative.

C. A registrant shall ensure that a controlled area associated with a Class 4 laser is:

1. The responsibility of a LSO;

2. Posted in accordance with this Article;

3. Access controlled by the LSO or a trained, designated representative; and

4. If an indoor controlled area:

a. Equipped with latches, interlocks, or another means of preventing unexpected entry into the controlled area;

b. Equipped with a control-disconnect switch, panic button, or an equivalent device for deactivating the laser during an emergency;

c. Operated so that the person in charge of the controlled area can momentarily override the safety interlocks during tests that require continuous operation to provide access to other personnel if there is no optical radiation hazard at the point of entry and the entering personnel are wearing required protective devices; and

d. Controlled in a way that reduces the transmitted values of laser radiation through optical paths such as windows, to levels at or below the applicable ocular MPE and AEL in R9-7-1426. If a laser beam with an irradiance or radiant-exposure above the applicable MPE or AEL will exit the indoor controlled area (as in the case of exterior atmospheric beam paths), the registrant and the operator are responsible for ensuring that the beam path is limited to controlled air space or controlled ground space.

D. If a panel or protective cover is removed or an interlock bypassed for service, testing, or maintenance, a registrant shall establish an accessible controlled area. The registrant, through a LSO or a designated representative, shall comply with laser safety requirements for all potentially-exposed individuals.
