Silica Respiratory Protection

Silica Dust Mask Requirements in Australia

Since 1 September 2024, new national regulations apply to all work involving crystalline silica, including concrete, brick, pavers, grout, mortar, tiles, sandstone, and any other material containing 1% or more crystalline silica.

Under Australian WHS regulations and AS/NZS 1716:2012:

• P2 is the legal minimum for all silica dust exposure in Australia.
• P3 is required for high-hazard silica environments and licensed asbestos removal work.
• Fit testing is mandatory for all tight-fitting masks before use, and every 12 months thereafter.
• Workers with facial hair at the seal point must use a PAPR with a loose-fitting hood or helmet, as tight-fitting respirators cannot provide a reliable face seal.

Silica Dust Respirator Range at Absafe

At Absafe, we stock complete mask-and-filter kits for immediate setup, individual replacement parts, and PAPR components from the industry's most trusted names, such as 3M, Sundstrom, and CleanSpace.

Disposable Silica Dust Masks

A disposable silica dust mask is a single-use negative-pressure respirator with a built-in filter. Certified to P2 under AS/NZS 1716, it suits lower-duration silica tasks and situations where maintaining a reusable mask isn't practical.

Main features:

• No cartridge changes – the entire mask is discarded after use.
• Must be fit-tested on the individual wearer.
• Duckbill and flat-fold styles to suit different face shapes.
• Some models include an exhalation valve to reduce heat and moisture build-up during longer shifts.

Reusable Half-Face Silica Dust Respirators

A reusable dust mask for silica uses replaceable cartridges and provides a more consistent, testable seal than a disposable option. It's the better long-term solution for workers regularly exposed to silica dust: concrete cutting and grinding, demolition, tunnelling, and masonry work.

At Absafe, you can buy complete mask-and-filter kits (mask body, cartridges, and all fittings included) or individual silica dust respirators.

Main features:

• Use P2 cartridges for standard silica work; P3 cartridges for higher-hazard applications.
• Combination cartridges are available when chemical vapour hazards are also present.
• Don't suit workers with facial hair at the seal point.
• Lower ongoing cost than disposables for regular users.

Full-Face Respirators for Silica Dust

A full-face respirator for silica dust with P3 filtration is the best choice for the highest-hazard silica environments: high-silica natural stone, combined silica and chemical vapour risk, or tasks where eye protection is also needed.

Full-face masks cover the entire face, including the eyes, and deliver a tighter seal than half-face options. They are also the only tight-fitting mask type capable of achieving true P3 protection.

Main features:

• Available with combination cartridges for mixed dust and gas/vapour environments.
• Requires fit testing.
• Built-in eye protection eliminates the need for separate safety glasses.

PAPR – Powered Air Purifying Respirators for Silica Dust

A PAPR is the right solution when workers cannot achieve a reliable face seal, whether due to facial hair or face shape.

A battery-powered motor draws air through a P3 filter and continuously supplies filtered air under positive pressure to a loose-fitting hood or helmet. Because filtered air is continuously supplied under positive pressure, contaminated air cannot enter through gaps around the hood or helmet.

Main features:

• No fit testing required for loose-fitting hood and helmet configurations.
• No breathing resistance – the motor does the work, reducing fatigue on long shifts.
• Compatible with hard hats, hearing protection, and face shields, which is important on sites with multiple PPE requirements.

Absafe stocks complete PAPR kits as well as individual components – hoods, helmets, filters, batteries, and breathing tubes – for sites already running a powered air program.

Choosing the Right Silica Protection

Situation	Recommended Protection
Occasional silica exposure, clean-shaven	Disposable P2 silica dust mask, fit tested
Regular silica work, clean-shaven	Half-face respirator with P2 filter, fit tested
High-hazard silica, clean-shaven	Full-face respirator with P3 cartridges, fit tested
Any silica work with facial hair present	PAPR with loose-fitting P3 hood or helmet
Extended shift with high silica exposure	PAPR for greater comfort and consistent protection across an entire full shift
Combined silica and gas or vapour hazard	Half-face or full-face respirator with combination cartridge, or PAPR with ABEK+P3 filter
