Respirable Dust Sampling using the Cyclone Sampler
Once the pump is mounted on the worker in a
satisfactory way it can be switched on. IMPORTANT:
The start time of the sample should be noted.
10. At the end of the sample switch the pump off
and note the finish time of the sample. Remove
the sample train from the worker, and once away
from the sample location re-check the flow rate
of the sample pump (as per MDHS14/3). Ensure
that the flow rate check is carried out as quickly
as possible to minimise the chance of collecting
anything that may affect the final result. Remove
the filter cassette from the cyclone sampler.
Open the filter cassette, carefully lift out the filter
and post weigh it. If the sample is to be sent to
a laboratory for further analysis, carefully transfer
the filter onto the support grid in a transport
cassette and snap the transport cassette shut.
The start and finish times, sample duration,
worker's name, start and finish flow rates, pre and
post sample weights and other relevant details of
the sample should be noted down and indexed to
the filter paper by number or code.
