There are two Australian/New Zealand Standards covering personal respiratory protection and risk management. These Standards form a basis for the selection, use and maintenance of RPE in Australian and New Zealand workplaces. When respirator use is required in the workplace, respirators shall conform to the requirements of AS/NZS 1716.
AS/NZS 1715:2009 Selection, use and maintenance of respiratory protective equipment. This Standard offers information to employers and users on different types of RPE, how to select the right type for the job and how to correctly maintain it.
AS/NZS 1716:2012 Respiratory protective devices. This Standard offers information to manufacturers, suppliers, employers and users by setting out performance requirements for different types of RPE
In accordance with the test in AS/NZS 1716 there are three classes of particulate filter classified:
|Particulate Filters||EFFECTIVE AGAINST|
|Class P1||intended for use against mechanically generated particulates of sizes most commonly encountered in industry. Has a low to medium absorption capacity filter|
|Class P2||intended for use against both mechanically and thermally generated particulates. Has a medium absorption capacity filter|
|Class P3||intended for use against all particulates including highly toxic materials. Has a high absorption capacity filter. Nevertheless this can only be achieved in a full face respirator|
