Some workers are more affected by dust: those with asthma, heart or lung conditions, pregnant workers and new starters. Clean air zones create low-exposure spaces so they can work safely without being sidelined.

Identify needs and plan zones

Use inductions and occupational health input to identify vulnerability sensitively. Choose rooms that can be kept clean (offices, welfare, specific work areas) and position them away from dusty routes and processes.

Set up the zone properly

Seal obvious gaps, reduce through-traffic and keep doors closed. Use air purifiers, for example a mobile unit such as a MAXVAC Dustblocker in welfare spaces, to reduce airborne particulate. For respirable or carcinogenic dust risks, specify H14 filtration. If practical, create slight positive pressure to resist ingress.

Operate and monitor

Display simple door rules and occupancy limits. Check PM levels with a portable meter at start, mid-shift and during nearby dusty tasks; adjust controls if trends rise. Keep housekeeping vacuum-only and schedule cleaning outside peak activities.

Integrate with job planning

Sequence high-dust work when vulnerable workers are off the floor or reassign tasks temporarily. Ensure RPE is available and fit-tested for anyone entering dusty areas, but design work so they rarely need it.

Practical takeaways

• Pick rooms that can stay clean and keep them out of dusty traffic.
• Use H14-filtered purification and door discipline to maintain air quality.
• Monitor PM trends and adjust before complaints arise.
• Vacuum-only housekeeping; clean outside peak dust times.
• Plan shifts and tasks so vulnerable workers avoid exposure.

Clean air zones are a practical inclusion measure that protect health and keep experienced people contributing fully to the job.
