The role of surface and airborne transmission o fCOVID-19 remains unclear, therefore compliance testing focuses on ensuring cleaning is completed to a high standard.
We are still learning how extensive and intermittent lockdown building closure is changing mechanical services operation, plumbing use and cleaning regimes. These changes may contaminate our indoor environments. Mould growth through poor climate control and Legionnaire disease outbreaks from bacteria in unused pipes and taps are identified risks.
We understand the demand on organisations to develop COVID-safe plans but realise that expertise is required to create a robust solution.
Consequently, LITMAS staff drove the recent publication of the Indoor Air Quality Association Australia (2020) Draft Reference and Guidelines for Post Cleaning Validation of Buildings Contaminated with SARS-CoV-2 and co-authored the even more recent A Guide to Buying P2, or Equivalent, Respirators for use in the Australian & New Zealand Work Environment.
The IAQAA Guideline makes clear recommendations on the necessary documenting procedures and post-cleaning testing methods.
We check your processes and their documentation to ensure they are compliant with International, National and Local Government requirements and with the IAQAA Guidelines.
Most recently we have seen buildings and transport vessels undergoing “deep cleaning” after cases of COVID-19 as contamination has taken hold of most of our indoor spaces. The Guide tells us, that in accordance with international agreement, ATP (adenosine triphosphate) measurement is not enough on its own to prove a surface is hygienically clean, as it is prone to both over- and under-estimating biological material on a surface.
LITMAS supports clients in the process of deep cleaning their building or transport vessel, and provides training in post-cleaning sampling according to the IAQAA Guidelines.
We conduct laboratory analysis to support the setting of ATP and debris clean-up targets, providing you with evidence that the required standard has been met.
