APPLICATION

An employer is required to demonstrate compliance to AS/NZS 1715 or any of the legislated Codes of Practice in terms of risk management. It is also an employer responsibility to ensure other means of hazard control have been investigated prior to introducing respiratory protection initiatives.

RISK ASSESSMENT

The AS/NZS 1715:2009 describes respiratory risk assessment along with a Respiratory Protection Programme and the appointment of a Programme Administrator where respiratory protective equipment (RPE) is required to be worn. Some of the risk assessment requirements are:

• Ensure the workplace is not a confined space. This can only be determined by measurement of the risk atmosphere for safe oxygen levels throughout the working period.  Negative pressure respiratory protection cannot supplement oxygen.
• Evaluate tasks to determine if RPE will compromise vision, communications or other PPE.
• The employer must provide training in the cleaning, safe use and limitations of RPE at the commencement of employment.
• The Programme Administrator must ensure a compliant fit test has been carried out for all users of RPE and maintain suitable records. The AS/NZS 1715:2009 describes both Qualitative and Quantitative fit test methods.
