A key component of WES compliance for RCS (Respirable crystalline silica) is the use of Respiratory Protective Equipment (RPE) and the associated training of workers. The use of RPE represents part of the final tier of the Hierarchy of Controls (the last line of defence) and should only be considered after the higher tiers have been implemented and/or no other safety measures are available.
Every worker should use a tight-fitting respirator with an effective face seal.
A documented Respiratory Protection Plan is a requirement of the Australia/New Zealand Standard (AS/NZS 1715) that covers personal respiratory protection and risk management in the workplace. The Process and Plan should include these elements:
• Exposure assessment: The determination of what hazards are present and at what levels
• Appointment of a Program administrator
• Respirator selection: Information used to select respirators
• Medical evaluation: Copies of screening/evaluation documents and questionnaires
• Respirator training: Documents used for the training of new employees and refresher training of existing employees
• Issue of RPE
• Fitting of equipment
• Wearing of RPE (where required)
• Respirator Maintenance: Comprehensive procedures for inspection and maintenance of respirators, and the schedule for cartridge changes
• Disposal of equipment
• Record Keeping
• Program evaluation: The criteria used to audit the program (every year at a minimum), and summaries of findings
Every worker should use a tight-fitting respirator with an effective face seal. Types include Disposable, Reusable and Powered Air Purifying Respirators (PARP). At the very least, a P2/N95 rated half-face respirator should be worn. Importantly, there is no one-sizefits-all approach, and some people may need to try a variety of masks before the correctly fitted and appropriate respirator is found.
