MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FILTER SATURATION TESTING.
Regular filter checks and monitoring (once a week is recommended) to test quality of the
air breathed in by operators and filtration efficiency. Filter challenge tests can be carried
out during routine Service and Maintenance procedures once every 6 months as
described in the Operational Safety Log Book.
The recommended procedure for testing the efficiency of the system requires a GASTEC
Volumetric Detector Pump and Gastec Chemical Detector Tubes. Test the quality of air
by sampling at eye and mouth level at regular intervals once a week with Gastec tubes
calibrated for the particular compound in concentrations below its respective OEL
(Occupational Exposure Limit) MEL (Maximum Exposure Limit) or OES (Occupational
Exposure Standard (or MAK in Germany and/or TLV in the USA).
Please refer to the Chemical Listing, Adsorption Index and Gastec Detection Guide
published in our Operational Safety Log-Book.
CLEANING
The materials used to construct the Airone FC750 Fume Cupboard have been selected
to give maximum durability and a long life. It is beneficial however to regularly clean and
decontaminate the internal and external surfaces.
It is recommended that the cabinet is switched on during any cleaning procedure and that
suitable protective clothing (face-mask, gloves and safety glasses) is worn.
All surfaces should be cleaned with a mild detergent solution then finished off with a damp
cloth and wiped dry.
If required, the rear/upper baffles can be removed for cleaning. It is recommended that
two people undertake this operation.
Remove the upper screws from the rear baffle, then undo and remove the thumbscrews
supporting the front of the upper baffle and allow in it fold down flat against the rear baffle.
Carefully remove the remaining bottom two screws holding the rear baffle whilst
supporting it.
