SECTION 252:410-15-2. Controls and security

(a)   Area controls. Permanent x-ray industrial radiographic installations shall have high radiation area entrance controls as described in 10 CFR 34.33.

(b)   Temporary job sites. At temporary job sites, a radiographer must maintain surveillance over the radiation area during each operation to ensure no one enters the area when radiation is being produced.

(1)   Barriers. Ropes and/or barriers should be used when practical to help prevent entry. During pipeline industrial radiographic operations radiation signs and barriers must be positioned in a manner to prevent individuals from entering the area when radiation is being produced.

(2)   Posting of radiation areas. Before beginning an industrial radiography operation at a temporary job site, a permittee must identify and post the radiation areas and high radiation areas, or designate a single restricted area based on the exposure limits established in 10 CFR 20.1301 for members of the public. If only a single area is designated, both signs must be posted at the area boundary.

(c)   System security. The control panel of each system shall be equipped with a locking device that prevents unauthorized use of the system or accidental production of radiation. This control panel must be kept locked and the key stored in a separate secure location except when a radiographer or assistant radiographer has the system under direct visual surveillance.

(d)   Labeling. X-ray tube housings and control boxes must be labeled according to 252:410-13-2(a).
