A Great Free App if you work at height – update



Simple to use and a handy tool for checking fall clearance distances.

‘Glad to hear it is getting a good reception in Europe. I apologize it is taking so long to update the app to also work in metric units, but at least it does have the EN 355 PEA. Our programmer should have the metric option uploaded next week but it will take a further week to get approval from Apple to post the next version on the App store. After that we will be working on the Android and Blackberry versions.
With regards correlation to the EU standards, they generally give conservative values for worker masses up to 100 kg. For example, EN355 directs manufacturers to specify clearance based on the total fall distance of the test mass (2x lanyard length plus PEA deployment) plus 1m which is fairly accurate when the 100 kg worker has a factor 2 fall, but grossly conservative when the worker is anchored higher than his feet.
The Lite App follows more accurate physics in that it accounts for the elevation of the anchorage, whether a worker is standing, kneeling, etc. The Lite App still assumes full deployment of the PEA (which is 1.75m if you have selected an EN 355 PEA).
The PRO version, when released hopefully in August, will calculate the PEA deployment based on the user’s weight (mass) and the free fall (determined by the App according to user’s specified lanyard length and anchorage height), and the lowest average force that would allow a PEA to pass the EN355 standard.
Thus the Lite App already calculates less clearance than would be specified by EN 355 when the fall is less than factor 2. The Pro App will reduce this further when the user weight and free fall reduces the PEA deployment below what occurs in the EN355 testing.’
