COVID-19 has brought about an increasing focus on respiratory protection.  As part of this fit testing has become a priority – in the health sector, emergency response, essential businesses and businesses potential returning to operation post Alert Level 4.  NZOHS has developed a training programme for Respirator Fit Testers – this is currently a four stage programme – (a) Webinar – Respirator Protection and Fit Testing – why, options, how; (b) online learning resources and questionnaire; (c) interactive, practical online training session (numbers restricted/dates to be advised); (d) competency assessment (options, numbers restricted/dates to be advised).

The dates for the two final sessions are dependent on number of registrations, availability of gear (having access to fit test kit yourself is helpful, but not a requirement), and Governmental requirements under COVID-19 Alert level.

Registrations have closed (24th April 2020) – however, we will be opening another opportunity for fit tester training in the next 2-3 weeks.  Please email if you are interested  Those already registered will be contacted within the next 24 hours to confirm remaining training programme.  The webinar held on 20th April 2020 will be available online on the NZOHS website.
