The following query was received by a Norac Member:
I have received a request for some information from a fellow member regarding personal sampling pumps.
They have done a review of their pumps and have found that none of them are capable of achieving 4l/m so not suitable for assessing for the 10 minute STEL. They have spoken with Airbox who can manufacture personal pumps which would achieve 4l/m but want to know whether it’s worth their while.
The questions are:
Whether or not you’re personals will run at 4l/m
Do you routinely do 10 minute personals to assess against 0.6f/ml
Would it be worthwhile having pumps which would run at 4l/m
The response can be seen within the attached document.
