Industrial Hygiene Monitoring

Monitoring Instructions

1. Field sampling strategy
2. Pre-sampling calibration of equipment (if active sampling)
3. Preparation of sampling media
4. Sample identification
5. Issue to the Wearer
6. Prepare the sampler – instruction given by laboratory
7. Relevant data on data sheet
8. Instruction to wearer
9. Start sampler and note the time on data sheet
10. Instruction to Wearer
    1. Sample duration – as specified in program (field sampling strategy, mentioned above)
    2. Breaks / lunch – should be worn through breaks / lunch, but local circumstances may dictate
    3. Note incidents during sample period; if possible, maintain a log sheet
    4. RPE – If any Respiratory Protective Equipment (RPE) is worn during the sample period, the personal monitor should be left on and running (outside the RPE) and full details of the type of RPE worn recorded on the data sheet.
11. Retrieve Sampler – stop the sampler and note the time on the data sheet
12. Post-sampling calibration of equipment (if active sampling)
    1. Calculation of average flow rate (the sample is considered invalid if there is a +/- 5% difference between the pre- and post-sampling calibration flow rates)
    2. Calculation of total air volume sampled (in liters)
13. Completion of sample form
14. Return of sampler and blank to lab within a “reasonable time” (1-2 days after sampling).
