multiple connection ports for airline respirator hoses to allow worker mobility. Consider
installing a panel to permit the IH to test air quality on a routine basis.
NOTE for USAF: The test panel is required for quarterly testing.
Air Compressors. Oil lubricated breathing air compressors require a
high temperature or carbon monoxide alarm or both. If only a high temperature alarm is
used, the air supply must be monitored to ensure the breathing air does not exceed 10
parts per million (ppm) carbon monoxide. Compressors that are not oil lubricated must
still have the carbon monoxide level monitored to ensure it is below 10 ppm.
Compressors used to supply breathing air must be constructed and situated to prevent
entry of contaminated air into the air supply system. The breathing air compressor must
minimize moisture content so that the dew point is 5.56 oC (10 oF) below the ambient
temperature. The breathing air system must have suitable inline air-purifying sorbent
beds and filters. Sorbent beds and filter will have to be maintained per manufacturer's
Emergency Showers and Eyewash Stations. Provide where required.
Design in accordance with UFC 3-420-01, Design: Plumbing Systems.
Hygiene Facilities. These facilities are adjacent to or nearby the
operation when employees are exposed to certain stressors such as asbestos,
cadmium, lead, etc. The facilities may be as simple as a hand washing station or as
complicated as multiple clean/dirty rooms in an asbestos delagging facility. Consult with
the local industrial hygiene department to determine the extent of and location for these
. This process begins before the conceptual design
complete. It is a strategy that documents the occupants' needs, verifies progress and
contract compliance and continues throughout the design, build and acceptance
process. DOD projects and construction offices have long used parts of the
commissioning process for military construction (MILCON) and some smaller projects.
To ensure that issues specific to ventilation are not overlooked, consider using ASHRAE
Guideline 1, The HVAC Commissioning Process.
