The Predicted Heat Strain Mobile Application: It’s here and it’s FREE!

Icon1024 12-07-2016, 5-24-18 PM

The University of Queensland project to develop a mobile phone application based on ISO 7933 Predicted Heat Strain is  complete.

Rational heat stress indices have been shown to provide a more accurate assessment of heat stress scenarios than many of the simpler and more commonly used empirical indices such as Effective Temperature (ET) and Wet Bulb Globe Temperature (WBGT).  A key advantage is that the rational indices also provide an avenue for the health professional to assess potential heat strain using additional parameters as well as evaluate potential controls. Despite this they have not been as readily accepted and utilised.  One of the barriers has been their complexity and the numerous calculations associated with their use, requiring access to a computer.

In order to address this issue, a project has been undertaken at The University of Queensland to develop and evaluate a mobile phone application based on the ISO standard 7933 Predicted Heat Strain. This freely available application allows investigators to input a number of parameters associated with the environment, task and individual to evaluate the work scenario’s potential risks and controls without requiring access to a computer. Based on the input data, the app uses a number of algorithms to produce predicted core body temperature and water loss graphs and reports. It is envisaged that the app will become a useful tool for the practicing occupational health and safety professional in the investigation and control of heat stress in the field. Once only accessible to academics or with the purchase of expensive equipment, this free app will take heat stress assessment for the health & safety professional to another level.

PHS App Snap

The App is now available in the Apple App Store. Just search for “PHS” and look for the icon seen at the top of this blog. Unfortunately the app is currently not available in Android format due to some recent system changes. It is hoped that the issue will be addressed in the near future. 

Below is a downloadable copy of the PHS App user guide.

    Does this app work on android? or windows phone?

    • Ross Di Corleto says:

      Unfortunately at this early stage we have only developed it for the Apple IOS system and were waiting to see what the demand would be. The response has been excellent so we will now look into the alternative platforms hopefully early in the new year depending on funding availability.

  • mat says:

    This is awesome thank you for your work and making it freely available.

    Can’t wait for it to be on android. Will promote it throughout my worksite as a hsr

  • Dr Graeme Edwards says:

    Very keen to use, but I need it on an android platform. Looking forward to its release. Well done. Graeme

  • Sandon Rothman says:

  • Tony says:

    Any update on the Android version at all? Really keen to look at how we may be able to use this.

    • Ross Di Corleto says:

      Hello Tony, Android and Windows versions of PHS are complete and currently going through final some hands on testing before they are released

  • JAne says:

    Great work UQ! Im an Aussie (alumni UQ) and now based in USA. I cant see the PHS app on the USA app store (apple)? Is it only available in Australia?

    • Ross Di Corleto says:

      Took me a while to track this down. It is available globally but in the US try PHS thermal in the search. This worked in Canada so could be the same in US.

  • Nicole says:

    Hi, is this available for Android yet? Thanks

  • Tanise Fuckner de Oliveira Galvan says:

  • Mark says:

    Hi Ross, is an Android version available yet?

    • Ross Di Corleto says:

      Hello Mark,
      the Android version has just completed testing and looks like the release date will be the week of the 15th January. Took longer than expected.

    Hi Ross,
    I just came across your website by chance and what the privilege too. I am pleased but not at all surprised to see another generous presentation of information that is very professional, backed up with science and verified through your dedication and passion.

    PS. Well done on the PHS app too, long needed in the industry.

    With my very best regards

  • Frans Droste says:

    App crashes every time I try to use it.
    I’ve installed it on a Samsung Galaxy A5 phone and a Samsung Galaxy Tab S2 tablet, both with Android 7.0.
    No difference.

  • Joy Atkinson says:

    Great idea, but the app crashesr every time I use it. Samsung & Nokia Android

    • Ross Di Corleto says:

      Hello Joy,
      It appears the app has been playing up recently in the Android version (IOS still OK). Developers have been notified and are currently working on it. Will let you know as soon as it is fixed.

  • Peta-Marie says:

    Hello

    The mobile PHS app, is there similar computer based program?

    Thank you

  • Harry Tucker says:

    Absolutely fantastic work on the App. It has really simplified our determination of Heat Strain on our employees and made numerous people lives so much better.

    Just one little issue, I cannot get the report email to work, it just comes up with ERROR! Report e-mail cannot be configured.

    Thanks again to all who toiled.

    • Hello Harry, appreciate the feedback. Great to hear the app is getting used and is useful.
      Your issue was passed onto the developers and should be fixed very soon in the next update.
      Regards
      Ross

  • Laurence Satie says:
