Florida Administrative Code › 64 - DEPARTMENT OF HEALTH › 64E - Division of Environmental Health › Chapter 64E-5 - CONTROL OF RADIATION HAZARDS › Section 64E-5.1406 - Access Control

Current through Reg. 50, No. 138; July 16, 2024
(1) Panoramic
				irradiators shall not be operated unless the following are met:
(a) Each entrance to a radiation room must
				have a door or other physical barrier to prevent inadvertent entry of personnel
				while the sources are exposed. Product conveyor systems can serve as barriers
				as long as they reliably and consistently function as a barrier. It must not be
				possible to move the sources out of their shielded position if any door or
				barrier to the radiation room is open. Opening the door or barrier while the
				sources are exposed must cause the sources to return promptly to their shielded
				position. The primary entry door must have a lock which is operated by the same
				key used to control source movement. The doors and barriers must not prevent
				any individual in the radiation room from leaving.
(b) Each entrance to a radiation room must
				have an independent backup access control to detect personnel entry while the
				sources are exposed if the primary access control fails. Entry while the
				sources are exposed must cause the sources to return to their fully shielded
				position and also must activate a visible and audible alarm to make the
				individual entering the room aware of the hazard. The alarm also must alert at
				least one other individual of the entry who is on site and who is trained to
				render or summon assistance promptly.
(c) A radiation monitor must be provided to
				detect the presence of high radiation levels in the radiation room before
				personnel entry. The monitor must be integrated with personnel access door
				locks to prevent room access when the monitor detects high radiation levels.
				The monitor must generate audible and visible alarms if high radiation levels
				are detected when personnel entry is attempted. The monitor can be located in
				the entrance or maze but not in the direct radiation beam.
(d) Before sources move from their shielded
				position, the source control automatically must activate conspicuous visible
				and audible alarms to alert people in the radiation room that the sources will
				be moved from their shielded position. The alarms must give individuals enough
				time to leave the room before the sources leave the shielded
				position.
(e) Each radiation room
				must have a clearly visible and readily accessible control which will allow an
				individual in the room to return the sources to their fully shielded
				position.
(f) Each radiation room
				must contain a control which allows the sources to move from the shielded
				position only if the control has been activated and the door or barrier to the
				radiation room subsequently has been closed within a preset time.
(g) Each entrance to the radiation room and
				each entrance to the area within the personnel access barrier of an underwater
				irradiator must be posted as required by Rule
				 64E-5.323, F.A.C. Panoramic
				irradiators also must be posted as required by Rule
				 64E-5.323, F.A.C. The sign can
				be removed, covered, or otherwise made inoperative when the sources are
				shielded fully.
(h) If the
				radiation room has roof plugs or other movable shielding, it must not be
				possible to operate the irradiator unless the shielding is in its proper
				location. This requirement can be met by interlocks which prevent operation if
				shielding is not placed properly or by an operating procedure requiring
				inspection of shielding before operating.
