RPE & HPD Fit-Testing

RPE & HPD Fit-Testing


  • RPE (respiratory protective equipment)

We conduct our RPE Mask Fit Testing in accordance with AS/NZ 1715 2009.  

Please note that OSHA has recently accepted two Modified Ambient Aerosol Condensation Nuclei Counter (CNC) Quantitative Respirator Fit Test Protocols. The new protocols went into effect on September 26, 2019. OHMS Hygiene have updated our equipment software to reflect the changes to the modified CNC Protocols.

  • HPD (hearing protection devices)

OHMS Hygiene uses the 3M™ E-A-Rfit™ Dual-Ear Validation System which makes it easy to measure every employee's unique level of protection in hearing protection fit testing and takes the guesswork out of managing compliance in your hearing conservation program.


  • Tests both ears simultaneously in less than 5 seconds.
  • Earmuff and Earplug testing capability
  • Tests at 7 standard frequencies - 125Hz to 8000Hz
  • Science-based, objective, quantitative testing

OHMS Hygiene can train and fit test your workers either on site or in house in the OHMS Hygiene offices located at West Perth.

The fit testing of RPE is legislated for in both the WA Occupational Safety and Health Regulations (1996) and the WA Mine Safety Inspection Regulations (1996); clauses 3.40 and 9.12, respectively.

Both regulations stipulate that if it is not practicable to control atmospheric contaminants in the workplace, “suitable respiratory protective equipment of a standard not less than that specified in AS 1715 is provided to employees in the relevant workplace”.

AS 1715 mandates:

  • that individuals are trained in using RPE;
  • what needs to be provided in the training;
  • fit testing; 
  • individuals being clean shaven.

OHMS Hygiene can train and fit test your workers using either:

  • the TSI Portacount for quantitative fit testing or
  • the 3M Hood for qualitative fit testing.


The fit testing of HPD is recommended within AS 1269.3 workers because the method of measuring attenuation of HPD in the laboratory (AS 1270) could differ significantly from real-world fitting and attenuation.

AS 1269.3 recommends:

  • that individuals are trained in the selection and use of HPD;
  • what needs to be provided in the training;
  • that evaluation of HPD is undertaken; 
  • individuals should be trained and fitted by an appropriately trained person with substantial knowledge of hearing protection.

OHMS Hygiene can provide training in HPD selection and use, then provide evaluation of fit with an objective fit testing method, the 3M E-A-Rfit™ Dual -Ear Validation System.

This equipment:

  • tests both ears simultaneously in less than 5 seconds;
  • has earmuff and earplug testing capability;
  • tests at 7 standard frequencies - 125Hz to 8000Hz.
