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
5154.1. Ventilation Requirements for Laboratory-Type Hood Operations:
The record of the most recent tracer gas test results and the "as used" test
configuration shall be maintained as long as the automatic system is operable and
thereafter for five years.
The face velocity required should be obtainable with the movable sashes fully
opened. Where the required velocity can only be obtained by partly closing the sash,
the sash and/or jamb shall be marked to show the maximum opening at which the
hood face velocity will meet the requirements of subsection.
Any hood failing to meet requirements of this paragraph shall be considered
deficient in airflow and shall be posted with placards, plainly visible, which prohibit
use of hazardous substances within the hood.
5154.2. Ventilation Requirements for Laboratory-Type Hood Operations:
(2) Inspections and maintenance of the HVAC system shall be documented in
writing. The employer shall record the name of the individual(s) inspecting and/or
maintaining the system, the date of the inspection and/or maintenance, and the
specific findings and actions taken. The employer shall ensure that such records are
retained for at least five years.
(3) The employer shall make all records required by this section available for
examination and copying, within 48 hours of a request, to any authorized
representative of the Division, to any employee of the employer affected by this
section, and to any designated representative of said employee of the employer
affected by this section.

Laboratory Fume Hoods, 5.0 TESTING LABORATORY FUME HOODS
5.2 Test results: a permanent sticker shall be affixed to the laboratory fume hood.
National Fire Protection Association, Standard NFPA 45, 2011
8.12.2 A sign containing the following information from the last inspection shall be
affixed to each hood, or a properly maintained log of all hoods providing the
following information shall be maintained:
(1) Inspection interval
(2) Last inspection date
(3) Average face velocity
(4) Location of fan that serves hood
(5) Inspector’s name
(Continued on Next Page)
Individuals performing fume hood testing
should affix a label on the fume hood or
record in appropriate documentation the
person(s) performing the test, their affiliation
and the information listed.
