Maintenance work is unpredictable and often exposes crews to mixed dusts and awkward access. PPE is the last line of defence, not the first. It must be selected for the task, fitted correctly, and maintained so it actually protects people. That includes masks, gloves and helmets used in combination with good dust control.

Select PPE based on risk, not habit

Start with a short task-based risk review: what dusts, how they are generated, and for how long. For silica (RCS), the HSE WEL is 0.1 mg/m³, so plan controls accordingly. Prefer engineering controls first, then match PPE to the residual risk. Ensure compatibility between items so seals are not broken by eyewear or helmet straps.

Respiratory protection

Choose RPE suitable for the dust hazard and duration. FFP3 disposables or reusable half masks with P3 filters are common where fine dust is present. Fit-testing is essential for tight-fitting RPE, and wearers should carry out a seal check every time. Keep spares and a change-out schedule based on time, resistance, or hygiene.

Hand and head protection

Gloves should protect from abrasion and contamination while preserving dexterity. Helmet selection should consider impact risks, low headroom, and compatibility with visors, ear protection and RPE. Where visibility is poor, high-contrast or reflective markings help team communication.

Use, maintenance and storage

Brief crews on when PPE is mandatory and how to don/doff without contamination. Assign personal kits to reduce sharing. Store RPE in clean, sealed bags; dry gloves between shifts; and retire damaged or soiled items promptly. Keep a simple log for inspections and fit-test dates.

Integrate PPE with dust controls

PPE sits within a wider approach: prevent dust at source, control what becomes airborne, and clean surfaces without re-suspending dust. PPE closes the gap when other controls cannot eliminate exposure.

• Fit-test tight-fitting RPE and check the seal every use
• Select gloves and helmets that do not compromise RPE performance
• Set filter change schedules and keep clean storage for RPE
• Use PPE only after applying engineering controls and safe methods
• Record checks; replace damaged or contaminated items immediately

When PPE is practical, compatible and well maintained, crews stay protected through the unpredictable demands of maintenance work while the job keeps moving safely.
