Ensuring the prescribed maintenance routines are being completed and recorded within the system logbook.
-
Condition check of fan, filters, electrics.
-
Performance testing according to recommended face velocities.
-
Visual check that operators are working within effective area.
-
Visual check of effectiveness using, for example, smoke tubes.
Recommended face velocities are as follows:
Fume control: Minimum 0.5m/s
Light dust control: Minimum 1.0 m/s
Heavy dust control: 1.2
–
