Barriers. Design protective barrier partitions to protect
occupants or equipment in rooms, spaces and compartments from fire, smoke,
physical security purposes; reference Appendix C for specific radiation
shielding criteria. Reinforced masonry or concrete partitions are
strongly desirable around areas where the physical security of valuables
or drugs is required; reference Section 14, Physical Security.
Protection. Use bumper guards on walls in areas subject to
frequent abrasion and impact, such as corridors, utility rooms, central
processing and distribution (CPD), gurney storage and others. Bumper
guards shall comply with the requirements in Section 12, Accessibility
Provisions for the Disabled, if they are used as handrails in corridors
and accessible pathways. Consider the use of bumper guards above the
floor base at reception counters, nurses stations and dispensing windows
that are designed for accessibility by wheelchair-bound patients.
Mechanically mount bumper guards to appropriate wall blocking where steel
stud partitions are used and extend outward from the wall to afford the
needed protection. Provide corner guards at outside corners of walls,
corridors, and in areas and rooms subject to damage by mobile equipment.
Design corner guards to extend from the floor to the finished ceiling.
Masonry partitions also require corner guards. Do not use bullnose
masonry corner units.
Reinforcement. Wall partitions require additional reinforcing
for positive attachment of surface-mounted items such as casework, wall
bumpers, toilet accessories, and other equipment.
Ceilings. Select a ceiling system based on initial cost,
surface visual appeal, resistance to moisture, fire resistance rating,
lighting, HVAC outlets, security, maintenance, and acoustical
requirements. Reference Appendix A.
Support. Use of suspended ceiling surfaces for the direct
support of intravenous infusion tracks, cubicle curtain tracks, and
ceiling lights is not acceptable. Ceiling-mounted accessories shall be
secured through the ceiling to secondary support members. Use universal
suspension systems in all radiographic rooms --- reference Section 16,
Medical and Dental Equipment, and Appendix C (Universal X-Ray Room).
Utility Access. Provide maximum accessibility in corridor
ceilings to the mechanical and electrical distribution systems. Do not
use concealed-spline ceiling systems requiring special tools to lower tile
assemblies. Color-code the access panels into ceiling plenums with tabs
to identify the type of utility present. Reference Section 19, Integrated
Moisture Protection. When acoustic treatment is required in
the presence of high levels of moisture, use plastic-faced acoustic tiles.
Maximum ceiling heights shall be as
indicated in Appendix A.
