In order to ensure a safe working environment for personnel working in laboratories, all containment equipment & devices should be performing according to their optimal state.
Over time, due to exposure to hazardous chemicals or biological agents and use and misuse, general wear & tear results. It is thus recommended that a periodic check (of at least two times per year) is conducted on the primary containment equipment & devices to prolong the life cycle of the fume hoods as well as to ensure the safety of the end users.
The following is a list of the tests and inspections will be conducted by INAXES with this proposal.
Fume Hood Maintenance
General lubrication on the required mechanical parts
Checking of general electrical services & appliances such as lightings and installations
Visual inspection on the miscellaneous services for leakage
Face Velocity Verification
Verification of Fume Hood face velocity with a calibrated anemometer
Smoke Test (dry-Ice)
Local & large volume smoke test to be conduct on fume hood to check for excessive turbulence and any possible cross draft
Duct work (for visible area only)
Visual inspection of the duct work condition, to ensure corrosion or leakage free
Visual inspection of flow controller installed for any corrosion or defects
Visual inspection on exhaust fan belt tension and fan housing
Any other General Services required, such as:
Check noise comparing in several running condition
Check room Temperature and Humidity condition trend during inspection period
Submission of face velocity tabulation report in accordance with applicable test standard (Please see attached report form)
Supply of individual fume hood verification sticker for safety audit on specific tests/inspections, to remind users of next service date
