U.S. OSHA, 29 CFR, Part 1910, Occupational Safety and Health Standards, Subpart
Z, Toxic and Hazardous Substances,1910.1450,C4(h):
Quality and quantity of ventilation should be evaluated on installation, regularly
monitored (at least every 3 months) and reevaluated whenever a change in local
ventilation devices is made.
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 Biosafety Level 3 facility design and operational procedures must be documented.
The facility must be tested for verification that the design and operational parameters
have been met prior to operation. Facilities should be re-verified, at least annually,
against these procedures as modified by operational experience.
The Biosafety Level 4 facility design and operational procedures must be documented.
The facility must be tested for verification that the design and operational parameters
have been met prior to operation. Facilities should be re-verified annually against these
procedures as modified by operational experience.
California OSHA – Division of Occupational Health & Safety (DOSH) Subchapter 7.
General Industry Safety Orders, Group 16. Control of Hazardous Substances,
Article 107. Dusts, Fumes, Mists, Vapors and Gases
5143. General Requirements of Mechanical Ventilation Systems
(5) The ventilation rate of every mechanical ventilation system used to prevent harmful
exposure shall be tested after initial installation, alterations, or maintenance, and at
least annually, by means of a pitot traverse of the exhaust duct or equivalent
measurements. Records of these tests shall be retained for at least five years.
National Fire Protection Association, Standard NFPA 45, 2011
7.5.3 Explosion shields and special explosion-containing hoods shall be inspected prior
to each use fire deterioration, especially transparent shields and sight panels in special
explosion-containing hoods.
8.7.3 Fans shall be located and arranged so as to afford ready access for repairs,
cleaning, inspection, and maintenance.
