SEFA 1–2006 Recommended Practices for Laboratory Fume Hoods
5.5 Fume hood maintenance procedures primarily consist of clean up, adjustments,
lubrication and replacement of worn, damaged or nonfunctioning parts. Use good
housekeeping in laboratory fume hoods at all times Periodically clean sash(es)
exterior and interior surfaces, including light panel. Replace lamps periodically to
maintain adequate illumination.
Clean up should be accomplished by, or under supervision of a knowledgeable
laboratory safety officer and should include removal of the baffle for clean up of all
interior surfaces.
Lubrication of sash guides, cables, pulley wheels and other working parts should be
accomplished as required or in accordance with manufacturer’s recommendations.
Flush all spills immediately using neutralizing compounds as required and clean
thoroughly.
6.6.8 Operations and Maintenance
• Ensure regular maintenance on all system components.
• Ensure proper operation within specified tolerances.
• Ensure no unauthorized changes to hood systems.
• Ensure maintenance personnel are familiar with hazards and safe work
procedures.
• Ensure maintenance personnel are fully trained.

VS-35-03 (PERCHLORIC ACID HOOD DATA)
8. Design washdown facilities into the hood and duct. Use daily or more often to
thoroughly clean perchloric acid from the exhaust system surfaces.
13. Lubricate the fan with fluorocarbon grease.

and Maintenance:
Centralized monitoring of laboratory variables (e.g., pressure differentials, face
velocity of fume hoods, supply flows, and exhaust flows) is useful for predictive
maintenance of equipment and for ensuring safe conditions
