NFPA 30 Chapter 6 states:6.3.4* The storage cabinet shall not be
required by this code to be vented for fire protection purposes, and
vent openings shall be sealed with the bungs supplied with the cabinet
or with bungs specified by the cabinet manufacturer. However, if the
storage cabinet is vented for any reason, the cabinet shall be vented
directly to outdoors in such a manner that will not compromise the
specified performance of the cabinet and in a manner that is acceptable
to the authority having jurisdiction. Appendix A explains why:
 
A.6.3.4 Venting of storage cabinets has not been demonstrated to be
necessary for fire protection purposes. Additionally, venting a cabinet
could compromise the ability of the cabinet to adequately protect its
contents from involvement in a fire because cabinets are not generally
tested with any venting. Therefore, venting of storage cabinets is not
recommended. 

Hope this helps clear this up.

Dear members,

What is your opinion or experience with venting flammable storage
cabinets?
Our local fire department seems to be against the idea as it may
compromise
the integrity of the cabinets. The design architects seem to agree with
the
fire dept. As a former lab worker, with a lot of  lab and cabinet
inspections to contend with, I am in favor of venting the cabinets  to
prevent odor from spills and or possible leaks of odoriferous
compounds.
Your opinion will be appreciated and the resulting comments posted for
the
list serve members.
Thank you in advance for your help.
