American National Standard for Laboratory Ventilation ANSI/AIHA Z9.5-2003
5.3 Exhaust system materials shall be in accordance with Chapter 5 of ACGIH’s
Industrial Ventilation: A Manual of Recommended Practice, Chapter 34 on Duct
Design of the ASHRAE 2001 Handbook – Fundamentals, and Chapter 6-5 of NFPA
45-2011.
Exhaust system materials shall be resistant to corrosion by the agents to which they
are exposed. Exhaust system materials shall be noncombustible if perchloric acid or
similar oxidizing agents that pose a fire or explosive hazard are used.
Exhaust airflow volume shall be sufficient to keep the temperature in the duct below
400
0
F (204
0
C) under all foreseeable circumstances.
5.3.2.3 Exhaust streams that contain concentrations of flammable or explosive vapors
at concentrations above the Lower Explosion Limit (LEL) as well as those that might
form explosive compounds (that is perchloric acid hood exhaust) shall not be
connected to a centralized exhaust system.

d. Fire Dampers: Fire dampers shall not be provided on any fume hood system.
Note that the Z9.5 reference to NFPA
Chapter 6-5 of NFPA 45-2000 has been
superseded by the material in Chapter 8 of
NFPA 45-2011.)
This section of the ASHRAE HVAC
Applications Handbook provides extensive
guidance to specific duct materials based on
resistance to the primary agents that will be
present and the fabrication and usage factors
to be considered.
