American National Standard for Laboratory Ventilation ANSI/AIHA Z9.5-2003
6.4 Routine performances tests shall be conducted at least annually or whenever a
significant change has been made to the operational characteristics of the hood
system. A hood that is found to be operating with an average face velocity more than
10% below the designated average face velocity shall be labeled as out of service or
restricted use and corrective actions shall be taken to increase flow. Each hood shall
be posted with a notice giving the date of the routine performance test, and the
measured average face velocity. If it is taken out of service it shall be posted with
A restricted use or out-of-service notice. The restricted use notice shall state the
requisite precautions concerning the type of materials permitted or prohibited for use
in the hood.
8.0 Inspection and maintenance shall follow an Inspection and Maintenance (I&M)
Program developed by the user.
8.1 Operations served by equipment being shutdown for inspection shall be safely
discontinued and secured during such maintenance. Lock-out/tag-out procedures
shall be implemented. Laboratory workers shall be notified in advance of inspection
and maintenance operations.

OPERATION AND MAINTENANCE:
Users should request periodic testing of the devices to ensure that they and the
connected ventilation systems are operating properly.
Also see Appendix 4 - Audit Form in
ANSI/AIHA Z9.5-2003, which provides a
comprehensive checklist for the Laboratory
Ventilation Management Program including
Inspection and Maintenance.
