Respiratory Masks are classified by the type of hazard they protect against, their APF and the specific substance(s) they’re approved for. There are other ways that you may also commonly see respirators classified as well, such as:
Native Pressure – Native Pressure Air Respiratory masks rely on the wear style to pull air in through filtered cartridge. This has the potential to add strain on the wearer as per medical guidelines required for masks.
Different types of respiratory masks available are:
Filtered Face piece – Disposable Respirators, also known as filtering face pieces are used to help protect against some particular hazards.
Reusable – There some options available for reusable respiratory masks. Used with particular filters, gas and combination of all required cartridges.
Full Face Masks – Full-face respirators cover the eyes and much of the face.
Positive Pressure Masks
These respirators do the work of pushing air to the head top or face piece; they can either be powered-air, using a battery-powered blower to pull air through a filter, or supplied-air, bringing clean air through a hose from a source outside of the contaminated work area (refer Appendix A, AS/NZS 1715, requirements for air quality for supplied air respirators).
Tight Fitted One – Tight-fitting respirators must be fit-tested when required, and users must perform seal checks every time a tight fitting negative pressure respirator release from a mask.
Loose Fitted – This type of respirators typically has a hood or helmet.
