Clean PPE zones protect workers and welfare areas from cross-contamination. Good design is about one-way movement, controlled air, and simple tasks that people will actually do every day.

Plan the layout and flow

• Define dirty, transition, and clean areas; mark them on the floor and with clear signage.
• Create a one-way route with the shortest path from work to de-dust point to welfare.
• Install MAXVAC Dustbarriers to separate zones and limit air mixing where permanent walls aren’t possible.

Control the air between zones

• Keep the dirty area neutral to slightly negative and the clean zone neutral to slightly positive so leakage goes the right way.
• Add an air scrubber sized on under-load airflow to reduce background particulate in the transition space.
• Close doors by default; add a small lobby if traffic is frequent.

Make de-dusting easy

• Place industrial vacuums at exits with tools for garments, boots, and gloves; avoid compressed air.
• Add hooks for overalls, sealed bags for transport, and bins for disposables.
• Provide handwashing immediately after glove removal so clean handling follows naturally.

Maintain the system

• Schedule short, regular vacuuming of floors and ledges; never sweep.
• Inspect barriers, seals, and filters; record checks weekly.
• Refresh training on the don/doff sequence and one-way rules.

Practical takeaways

• One-way zoning prevents backflow of dust.
• Use barriers and airflow bias to keep clean areas clean.
• Put vacuums where people need them and keep them maintained.
• Short, frequent housekeeping beats occasional deep cleans.

Well-planned zones reduce rework and support COSHH duties by limiting dust migration into welfare and offices.
