Exhaust Requirements
Ducting above the roofline is required to generate proper air dispersion of materials or
containments exhausted through the blower.
Each blower serving laboratory equipment shall be field labeled to indicate the specific
equipment served; and adequately sized by a qualified professional to provide exhaust
flow sufficient to maintain negative static pressure in all parts of the mechanical system
located indoors, required transport velocity, exit velocity, and volumetric rate.
Per ANSI/ASSP Z9.5, if flammable vapor or gas of combustible dust is present in the
airstream above 20% of the LEL/LFL, blower construction shall be as recommended by
AMCA 99-0401, classifications for spark resistant construction.
Exhaust stack design and discharge velocity shall be such that requirements in
ANSI/ASSP Z9.5 and NFPA 45 are met, in any event the discharge height shall be a
minimum of 10 feet above adjacent roofline and air intakes in the vertical up direction.
