TL;DR

PPE is the last resort in the hierarchy of controls: it sits below elimination, substitution, isolation, and engineering controls. If workers still need PPE after you have applied higher-order controls, the PCBU must provide it at no cost, ensure it fits, maintain it in working order, and train workers in its use (model WHS Regulations regs 44-47, verified 2026-05-10). Every person on a residential site must wear the site minimum kit: hard hat, high-vis, steel-cap boots, and eye protection. Task-specific kit (RPE, hearing protection, gloves) is layered on top based on the risk. Getting PPE selection wrong is not a compliance footnote: a P1 dust mask used for silica cutting gives inadequate protection where a P2 half-face is the minimum standard.

PPE in the hierarchy of controls

The model WHS Regulations require a PCBU to manage risks by working through a hierarchy of controls in order (Safe Work Australia, “How to manage work health and safety risks”, November 2024 edition, verified 2026-05-10):

  1. Elimination (remove the hazard entirely)
  2. Substitution (replace with a less hazardous option)
  3. Isolation (separate the hazard from people)
  4. Engineering controls (physical guards, ventilation, dust extraction)
  5. Administrative controls (procedures, rotation, signage)
  6. PPE (the last and least reliable layer)

PPE is least reliable because it depends entirely on the individual wearing it correctly, every time. A worker who removes a respirator for “just a minute” eliminates its protection for that minute. Higher-order controls work even when no one is watching.

PPE is still mandatory where the residual risk after higher controls cannot be reduced further. On a residential build, that is most of the time: you cannot eliminate the hazard of falling objects, so head protection is required.

PCBU duties under regs 44-47

Under model WHS Regulations Part 3.2 Division 5 (regs 44-47), if PPE is required at the workplace the PCBU must (Safe Work Australia, “PPE: WHS duties”, verified 2026-05-10):

ObligationWhat it requires
Provide suitable PPEPPE must be appropriate for the risk, fit the worker properly, and be compatible with other PPE being worn
No cost to the workerWorkers do not pay for PPE. The PCBU buys it or provides a PPE allowance. An allowance does not shift the responsibility: the PCBU must still confirm fit and adequacy
Maintain, repair or replacePPE must be kept clean, hygienic, and in good working order
Train and instructWorkers must be trained in correct use, storage, and care of their PPE
Inform workersWorkers must be told when PPE is required and why

Workers must use PPE as instructed (reg 46), and non-workers (visitors, clients on-site) must also comply with PPE requirements when at a workplace (reg 47).

Where two PCBUs share a worksite (e.g. the principal contractor and a subbi), the duty to provide PPE falls on both. A subcontractor provides PPE for their own workers; the principal contractor must confirm it has been provided before allowing the subbi to start work. See WHS duties when engaging subcontractors.

Site minimum: induction-issued PPE

Every person entering a residential construction site must have the site minimum kit on arrival, confirmed at induction. The site minimum is (Safe Work Australia, Construction Work Code of Practice, verified 2026-05-10):

ItemStandardNotes
Occupational protective helmet (hard hat)AS/NZS 1801:2024 (verified 2026-05-10)Replaces the 1997 edition. Must be in date, undamaged, and adjusted to fit
High-visibility safety garmentAS 4602.1:2024 (verified 2026-05-10)Vest or shirt; class depends on site conditions and traffic present
Safety footwear with toe protectionAS/NZS 2210.1:2025 (verified 2026-05-10)Steel-cap or composite-cap boots; also covers ankle support and penetration resistance
Safety eye protectionAS/NZS 1336:2014 (verified 2026-05-10)Safety glasses or goggles; task determines lens type

Hard hats have a manufacturer-stated service life: most are 3 years from first use, and the shell degrades from UV exposure even if undamaged. A cracked or sunbleached hard hat is out of compliance.

Task-specific PPE

Layer on additional PPE as the task demands. The risk assessment or SWMS will identify the requirement.

Respiratory protective equipment (RPE)

For dusty tasks, the minimum is a P2 filtering facepiece. P2 is the particle filtration class required for silica-generating tasks (concrete grinding, masonry cutting, fibre cement cutting) on a residential build. A P1 disposable mask does not provide adequate protection for silica dust and should not be used for these tasks (Safe Work Australia, “Silica: choosing and implementing control measures”, verified 2026-05-10).

RPE selection must follow AS/NZS 1715:2009 (Selection, use and maintenance of respiratory protective equipment, verified 2026-05-10). Note: Australia is transitioning to a new ISO-based suite of standards; AS/NZS 1715:2009 and AS/NZS 1716:2012 will both operate in parallel with the new standards until 2030 (Standards Australia, verified 2026-05-10).

Half-face respirators with replaceable cartridges are required for solvent vapours (paints, adhesives, solvents). The cartridge type must match the hazard (organic vapour vs. P2 particulate vs. combined). Workers who use any type of RPE beyond a disposable dust mask must be fit-tested before working in the hazardous environment, and trained in donning, doffing, seal-checking, and filter-change intervals.

For confined space entry where oxygen deficiency or toxic gas is possible, supplied-air or self-contained breathing apparatus (SCBA) is required, not a filtering facepiece. Filtering facepieces do not supply oxygen.

Hearing protection

Workers must not be exposed to noise above 85 dB(A) as an 8-hour time-weighted average (model WHS Regulations, verified 2026-05-10). On a residential site, angle grinders, jackhammers, nail guns, and circular saws routinely exceed this level.

Hearing protectors should be selected per AS/NZS 1269.3 (Occupational noise management, hearing protector program). Suppliers provide SLC80 ratings and class ratings; use the class appropriate for the measured or estimated noise level. Involve workers in selecting hearing protectors: a protector that is not worn because it is uncomfortable gives zero protection.

Gloves

Gloves are task-specific. Cut-resistant gloves for handling sheet materials with sharp edges and for reinforcement steel. Chemical-resistant gloves for adhesives, solvents, and concrete (wet concrete causes skin burns and dermatitis on extended contact). Heavy-duty gloves for demolition and handling rough masonry.

Gloves are incompatible with some tasks: operating rotating machinery (drills, lathes, grinders) with loose gloves creates entanglement risk. Match the glove type to the hazard and confirm it does not introduce a new hazard.

Sun protection

Outdoor work means UV exposure. AS/NZS 4399 covers sun-protective clothing. Additional measures include broad-spectrum SPF 50+ sunscreen applied every two hours, a broad-brim hat (compatible with the hard hat or worn between tasks when the head is not at overhead risk), and UV-blocking safety eyewear.

Compatibility and fit

Where multiple PPE items are worn simultaneously, confirm they are compatible and do not compromise each other’s protection. Common incompatibility issues on residential sites:

  • A half-face respirator seal can be broken by safety glasses with wide arms running behind the mask seal. Use goggles or safety glasses with no temple arms, or a full-face respirator.
  • Some hard hat designs are incompatible with certain ear muffs. Check that the muffs seat correctly against the skull when the hat is worn.
  • Chemical-resistant gloves that are too large for the worker create grip issues and can catch on equipment.

The PCBU must confirm that the selected PPE combination is compatible before issuing it.

Maintenance and inspection

PPE must be inspected before each use. Remove from service any item that is:

  • Cracked, broken, or structurally compromised
  • Past its manufacturer’s service life date
  • Contaminated (chemical exposure can degrade plastics and rubber even without visible damage)
  • Incorrectly sized or adjusted

Respirator filter elements have a service life determined by the hazard level and exposure time. A P2 disposable must be replaced when breathing resistance noticeably increases or the filter is visibly contaminated, or at the end of each shift at minimum. Cartridge respirators require filter changes per the manufacturer’s schedule, typically more frequently in high-dust environments.

What can go wrong

  • Wrong class of respirator for the task. A P1 dust mask for silica or asbestos work is the most common and most dangerous error. The filtration class must match the hazard.
  • RPE seal failure. Facial hair prevents an adequate seal on a half-face or full-face respirator. Workers with beards cannot use negative-pressure RPE for high-risk tasks; powered air-purifying respirators (PAPR) are the alternative.
  • Hard hat past service life. UV degradation of polycarbonate or ABS shells is not visible to the naked eye. Check the manufacture date stamped inside the shell and the in-service date.
  • High-vis class mismatch. If plant or vehicles operate on or adjacent to the site, a higher-class garment may be required. Confirm the class against the site conditions.
  • PPE allowance without follow-through. Giving a worker a PPE allowance and then not confirming fit or adequacy shifts no legal liability. The PCBU’s duty remains intact.
  • Visitors without site PPE. Clients, inspectors, and design consultants visiting the site must wear the site minimum. Keep spare hard hats and high-vis vests at the site office for visitors.
  • Storing PPE in the ute. UV, heat, and dust in an open ute tray degrade PPE. Helmets in direct sun and respiratory filters exposed to dust both have reduced service life. Store PPE in a cool, enclosed location between shifts.
