Periodic
Inspection
and Testing
(Continued)
8.13.1 When installed or modified and at least annually thereafter, chemical fume
hoods, chemical fume hood exhaust systems and laboratory special exhaust systems
shall be inspected and tested as applicable, as follows:
(1) Visual inspection of the physical condition of the hood interior, sash and ductwork...
(2) Measuring device for hood airflow
(3) Low airflow and loss-of-air-flow alarms at each alarm location
(4) Face velocity
(5) Verification of inward airflow over the entire hood face
(6) Changes in work area conditions that might affect hood performance
8.13.4.1 Air system flow detectors, if installed, shall be inspected and tested annually
8.13.4.2 Where potentially corrosive or obstructive conditions exist, the inspection and
test frequency shall be increased. 8.13.5.1 Air supply and exhaust fans, motors, and
components shall be inspected at least annually.
A.8.13.5.1 The annual inspection of air supply and exhaust fans, motors, and
components should ensure that equipment is clean, dry, tight, and friction-free.
Bearings should be properly lubricated on a regular basis, according to the
manufacturer’s recommendations. Protective devices should be checked to ensure
that settings are correct and that ratings have been tested under simulated overload
conditions. Inspections should be made by personnel familiar with the manufacturer’s
instructions and equipped with proper instruments, gauges, and tools.
8.13.5.2 Where airflow detectors are not provided or airflow rate tests are not made,
fan belts shall be inspected quarterly; double sheaves and belts shall be permitted to
be inspected semiannually.
American National Standard for Laboratory Ventilation ANSI/AIHA Z9.5-2003
8.7.1 Fans, blowers, and drive mechanisms shall be visually inspected weekly. Key
observations are abnormal noise or vibration, bearing noise, excessive temperature of
motors, lubricant leaks, etc.
8.7.2 V-belt drives shall be stopped and inspected monthly for belt tension and signs of
belt wear or checking.
American Conference of Governmental Industrial Hygienists (ACGIH)
INDUSTRIAL VENTILATION A Manual of Recommended Practice, 27th Edition
8.4.4 The (cooling) coil and (condensate) pan must be inspected and cleansed on a
regular basis.

OPERATION AND MAINTENANCE:
Preventive maintenance of equipment and periodic checks of air balance should be
scheduled.
