PPE is essential, but it only works when integrated with engineering and procedural controls. A plan that treats PPE as the last line of defence is easier to supervise, more reliable and more comfortable for workers.

Start with the hierarchy

Under COSHH, prevent and control at source before relying on PPE. For tasks producing silica, wood dust or fine particulates, specify tool-mounted extraction, consider water suppression and redesign the process where possible.

Align PPE with engineering controls

• Run local exhaust ventilation and, in small rooms, an air scrubber to reduce background concentration; MAXVAC Dustblockers can help maintain lower airborne levels during contained works.
• Choose filter classes appropriate to the hazard and consider H14 for very fine or carcinogenic dusts, particularly where bystanders are present.
• Check airflow under load and plan for filter loading over the shift.

Choose and manage RPE properly

• Select FFP3 or suitable reusable RPE for respirable dust; face-fit test all tight-fitting masks.
• Set change-out schedules for filters; do not wait for breathing resistance to climb.
• Manage compatibility with other PPE (eye, hearing, head protection) and set a facial hair policy.

Training, supervision and comfort

• Train workers to don, seal-check and doff without contamination.
• Plan work-rest cycles to manage heat stress and communication barriers.
• Record who wore what, when, and capture issues for improvement.

Practical takeaways

• Design tasks to minimise dust first; use PPE to control residual risk.
• Pair RPE with LEV and air cleaning; verify performance with a PM meter.
• Maintain filters, storage and hygiene so PPE protects every time.

Integrating PPE into a broader control strategy reduces reliance on perfect mask use and keeps exposure consistently below Workplace Exposure Limits.
