C.7.5 Air Quality
Adequate access shall be provided for periodic maintenance and cleaning of coils,
humidifiers and drain pans. Drain pans shall be designed and installed for proper and
immediate drainage of condensed water. A proper hydraulic head shall be provided for
drains with positive and negative air plenums to provide drainage and prevent
overflow.

8.4.4 The (cooling) coil and (condensate) pan must be inspected and cleansed on a
regular basis.

OPERATION AND MAINTENANCE:
Maintenance personnel should be trained to keep laboratory systems in good
operating order and should understand the critical safety requirements of those
systems.
High-maintenance items should be placed outside the actual laboratory (in service
corridors or interstitial space) to reduce disruption of laboratory operations and
exposure of the maintenance staff to laboratory hazards. Maintenance personnel must
be aware of and trained in procedures for maintaining good indoor air quality (IAQ) in
laboratories. Many IAQ problems have been traced to poor maintenance due to poor
accessibility.
Institute of Laboratory Animal Research, Commission on Life Sciences, National
Research Council, Guide for the Care and Use of Laboratory Animals, Eight
Edition, 2011:
Page 46: Treatment of recycled air for either particulate or gaseous contaminants is
expensive and can be rendered ineffective by improper or insufficient maintenance of
filtration systems. These systems should be properly maintained and monitored
appropriately to maximize their effectiveness. The successful operation of any HVAC
system requires regular maintenance and evaluation, including measurement of its
function at the level of the secondary enclosure.
Ensuring proper drainage for water that
condenses on cooling coils is extremely
important. Standing water in drain pans can
result in the rapid growth and proliferation of
mold, bacteria, and many infectious micro-
organisms that can enter the supply air
stream (that is, Legionella, Pontiac Fever,
etc.)
