Personal air monitoring turns abstract risk into numbers a worker can act on. It helps teams understand exposure from specific tasks and improve controls in real time.

Set clear purpose and choose the right kit

Decide whether you need task profiling, compliance screening or coaching. Select personal air monitors that suit the dust type and response time you need, and plan who will wear them on which tasks.

Collect usable data

Fit samplers in the breathing zone, log wear-time, and annotate tasks as they change. Capture short, high-exposure peaks; these often dominate dose. For RCS, remember the HSE WEL is 0.1 mg/m³ (8-hr TWA), so peaks matter.

Turn readings into actions

Use a simple traffic-light guide. Green: keep controls. Amber: slow cutting, increase water, check extraction under load, change a loaded pre-filter. Red: stop, review method and add control (e.g. on-tool extraction or enclosure) before restarting.

Coach with quick feedback

Review results the same day with the crew. Compare two runs of the same task, with and without improved controls, to show the gain. Repeat for new starters until they can set up controls unaided.

Practical takeaways

• Define why you are monitoring and who wears the device.
• Place the sampler correctly and record task changes.
• Link thresholds to specific actions the team can take immediately.
• Review data the same day to embed learning.
• Use findings to improve LEV, housekeeping and RPE choices.

Personal air monitors are most powerful when they prompt instant adjustments and build confidence. Keep the process simple, practical and focused on control, not blame.
