C.14.4 Hazardous Waste Storage and Handling
h. A separate ventilation system shall be installed for the storage room. Exhaust shall
be directed away from the building and the buildings’ air intakes. This ventilation
system shall be connected to the building’s standby power system and contain
appropriate filtration and monitoring devices.
American Institute of Architects, GUIDELINES FOR PLANNING AND DESIGN OF
BIOMEDICAL RESEARCH LABORATORY FACILITIES 1999
i. Autoclaves: The space must have adequate exhaust capacity to remove heat,
steam, and odors generated by the use of the autoclave(s). A canopy hood shall be
provided over the door of the autoclave. The autoclave space shall operate at negative
pressure to the surrounding areas.
j. Vacuum Systems: Vacuum system exhaust must be vented to the outside of the
building and not recirculated to the mechanical room.
ASHRAE, 2011 Handbook, HVAC Applications, Laboratories, Pg. 16.9 EXHAUST
SYSTEMS:
Laboratory exhaust systems should be designed for high reliability and ease of
maintenance. This can be achieved by providing multiple exhaust fans that are not
necessarily redundant or by sectionalizing equipment so that maintenance work may
be performed on an individual exhaust fan while the system is operating.
To the extent possible, components of exhaust systems should allow maintenance
without exposing maintenance personnel to the exhaust airstream. Access to filters
and the need for bag-in, bag-out filter housings should be considered during the design
process.
Depending upon the effluent of the process being conducted, the exhaust airstream
may require filtration, scrubbing or other emission control to remove environmentally
hazardous materials. Any need for emission control devices should be considered
early in the design so that adequate space can be provided and cost implications can
be recognized.
