(Chapter II-17.6.5.a) A service bay is a designated room, area or vault within an operating building for the intermediate storage/staging of explosives or explosives components awaiting initial or additional processing performed in that facility. Service bays are not intended to be used for long term storage or the staging of explosives or explosives components whose next manufacturing process is not performed within the facility containing the explosives. A service bay is a designated room, area or vault within an operating building for the intermediate storage/staging of explosives or explosives components awaiting either processing performed in that facility or transportation once intermediate or final processing in that facility is complete. Service bays are not intended to be used for long term storage/staging of explosives or explosives components. Change clarifies the storage requirements within a staging/service bay by specifically addressing intermediate storage/staging of explosives or explosives components that have undergone processing in the supported facility and are awaiting transportation outside the facility. 34 Change 11-23R1 Approved at the 66th DOE ESC Meeting on May 16, 2012. (Chapter II-18.7.a) For decontamination of real estate, reference DoD 6055.09-M.

Explosives Emergency Control Plansa. Each installation shall have a facility-specific written plan for the control of emergencies involving explosives (the plan may need to be broken down for each operating area). An explosives emergency control plan may be part of the facility’s overall emergency control plan. All facility personnel shall be trained in the plan’s content applicable to their area. The plan shall be available to personnel on a need-to-know basis for ready reference.b. Emergency situations that should be covered include the following:1. Fires and explosions.2. Floods.3.

Structural collapse is a structural component’s failure as a direct result of a facility losing structural integrity. This collapse must not result in explosives propagation, fatalities, or severe personal injuries.(3) Hazardous fragments or debris generated in acceptor occupied areas having an impact energy of 58 foot pounds (79J) or greater. The threshold pressure for eardrum rupture is 5 psi (34 kPa); one-half of the threshold pressure for lung damage is 15 psi (100 kPa). (see Chapter I of UFC 3-340-02)

(1) Overpressures greater than 15 psi (100 kPa) maximal effective pressure. The threshold pressure for eardrum rupture is 5 psi (34 kPa); one-half of the threshold pressure for lung damage is 15 psi (100 kPa), (see Chapter I-11.1 of UFC 3-340-02).(2) Structural collapse resulting from overpressure or debris impact.

Automatic fire suppression systems shall be installed in all buildings containing HE and plutonium, except storage magazines, firing chambers, or rooms used as firing chambers within explosives operating buildings. Change provides consistency with Chapter II-2.2.3.b.1 for Personnel Protective Restrictions and Requirements. The exemption of firing chambers reflects the inherent challenges of installing fire suppression in a chamber or room used for intentional detonations.

A diagram of the structure or room showing all points requiringmeasurements or visual inspection and location of surge protection devices should be prepared. Change removes requirement for LPS trend analysis. The committee determined that LPS trend analysis does not add any value to the documentation as readings vary based on weather and other variables that cannot be controlled. Data collected is not reliable to base maintenance decisions on. Acute changes in resistance or physical damage are better indicators of serviceability.
