Subchapter 7. General Industry Safety Orders, Group 16. Control of Hazardous
Substances, Article 107. Dusts, Fumes, Mists, Vapors and Gases
5154.1. Ventilation Requirements for Laboratory-Type Hood Operations:
The ability of the hood to maintain an inward flow as required by (c) above shall be
demonstrated using smoke tubes or other suitable qualitative methods upon initial
installation.
(5) The ventilation rate of every mechanical ventilation system used to prevent
harmful exposure shall be tested after initial installation, alterations, or
maintenance, Records of these tests shall be retained for at least five years.
U.S. Dept. of Health and Human Services, Centers for Disease Control and
Prevention publication: Biosafety in Microbiology and Biomedical
Laboratories, (BMBL) 5th edition 2009:
The operational integrity of a BSC must be validated before it is placed into service
and after it has been repaired or relocated. Relocation may break the HEPA filter
seals or otherwise damage the filters or the cabinet. Each BSC should be tested
and certified at least annually to ensure continued, proper operation
American National Standard for Laboratory Ventilation ANSI/AIHA Z9.5-2003
6.2 All newly installed, renovated, or moved hoods shall be commissioned to
ensure proper operation by laboratory personnel.
6.2.1 The commissioning process shall be overseen by a responsible person or
commissioning authority.
6.2.2 A written commissioning plan shall accompany design documents and be
approved by the commissioning authority in advance of construction activities. The
commissioning plan shall be available to all potential suppliers and contractors
prior to bid along with the other project documents. A commissioning plan shall
address operation of the entire ventilation system where the hoods, laboratories,
and associated exhaust air and air supply ventilation systems are considered
subsystems. The plan shall include written procedures to verify or validate proper
operation of all system components and include:
• Laboratory Chemical Hood Specification and Performance Tests
• Preoccupancy Hood and Ventilation System Commissioning Tests
• Preoccupancy Laboratory Commissioning Tests
