MAINTENANCE AND PERFORMANCE MONITORING:
SHOULD ONLY BE UNDERTAKEN BY A SUITABLY COMPETENT AND QUALIFIED PERSON)
Before removing any cover panels or accessing the service void to carry out
maintenance work, isolate the electrical supply first.
We recommend that a service programme be arranged with Safelab Systems Ltd.
Regular maintenance by our qualified personnel will ensure safe running of your
equipment and also ensure that you meet your requirements under COSHH regulation 9.
The minimum requirement to comply with COSHH Regulations is that the face velocities must be
monitored (at least once every 14 months) and a written record kept of the results. Tables printed
on the back pages of the Operational Safety Log-Book are suitable for keeping these records.
Six Monthly Maintenance
a)
Remove the rear and top baffles from their retaining lugs and clean both the baffle and the rear
chamber.
b)
Wipe the interior surface of the chamber with a damp cloth of diluted detergent solution
c)
Inspect the sash mechanism for corrosion and damage, lubricate pulley with light machine oil or
silicone spray.
Twelve Monthly Maintenance

d)
Carry out face velocity check across the open area of the sash at the normal working height in
accordance with BS EN14175-3, 5.2.1.1 and 5.2.2)
Using a 100mm dia. vane anemometer, readings should be taken at each of these grid positions
and each point should not be any more or less than 20% of the design velocity.
Record the mean velocity and update your record accordingly in line with COSHH requirements.
e)
Inspect the fire damper(s) (where fitted) and its release mechanism.
f)
Inspect the condition of the extract ducting, particularly the joints.
g)
Check the stability and condition of the discharge stack.
If the Fume Cupboard is frequently used for substantial quantities of corrosive substances, the six
monthly checks should be carried out monthly, the twelve monthly checks every six months.
