Okla. Admin. Code § 310:281-9-13

Current through Vol. 42, No. 7, December 16, 2024

Section 310:281-9-13 - Caution signs, labels and signals

(a)General.

(1) Except as otherwise authorized by the Department, symbols prescribed by 310:281-9-14 shall use the conventional radiation caution colors (magenta or purple on yellow background). The symbol prescribed by this section is the conventional three-blade design, as set forth in Appendix A of this Chapter.

(2) In addition to the contents of signs and labels prescribed in this section, a permittee may provide on or near such signs and labels any additional information which may be appropriate in aiding individuals to minimize exposure to radiation.

(b)Radiation Areas. Each radiation area shall be conspicuously posted with a sign or signs bearing the radiation caution symbol and the words:

(1) CAUTION or DANGER

(2) RADIATION AREA

(c)High Radiation Areas.

(1) Each high radiation area shall be conspicuously posted with a sign or signs bearing the radiation caution symbol and the words:

(A) "CAUTION" Or "DANGER"

(B) HIGH RADIATION AREA

(2) Each entrance or access point to high radiation area shall be:

(A) equipped with a control device that causes the level of radiation to be reduced below that at which an individual might receive a dose of 100 millirems in 1 hour upon entry into the area; or

(B) equipped with a control device that energizes a conspicuous visible or audible alarm signal in such a manner that the individual entering the high radiation area and the permittee, a supervisor of the activity are made aware of the entry; or

(C) maintained locked except during periods when access to the area is required, with positive control over each individual entry.

(3) The controls required by 310:281-9-13(c)(2) shall be established in such a way that no individual will be prevented from leaving a high radiation area.

(4) The controls required by 310:281-9-13(c)(2)(A) shall be constructed in such a manner that the primary radiation cannot be reactivated until all entrances have been secured, and the radiation on-off control is reset at the control panel.

(5) The controls required by 310:281-9-13(c)(2)(B) shall be constructed in such a manner that when the warning device is activated, it shall be necessary to shut off or secure the source of radiation and secure all tripped entrances prior to being able to de-activate the alarm system.

(6) Control devices required by either 310:281-9-13(c)(2)(A) or 310:281-9-13(c)(2)(B) shall be tested for proper operation at intervals not to exceed six months. If such testing indicates failure of the device, corrective action shall be taken immediately to restore the control device to proper working order.

(7) In the case of a high radiation area established for a period of 30 days or less, direct surveillance to prevent unauthorized entry may be substituted for the controls required by 310:281-9-13(c)(2).

(8) Any permittee may apply to the Department for approval of methods not included in 310:281-9-13(c)(2) and (7) for controlling access to high radiation areas. The Department may approve the proposed alternatives if the permittee demonstrates that the alternative methods of control will prevent unauthorized entry into a high radiation area, and that the requirement of 310:281-9-7(c)(3) is met.
