This week while doing an S&H audit Dennis and I came across a maintenance manager who moved us into the digital era (LOL)! We had always measured the rise and run of stairs and then compared this data to Table D-1 in 1910.24. This year Dennis handed down to me his Sears brand magnetic “angle finder” he used for his 30+ years in OSHA. But this week, as we went to measure the angle of a set of stairs the maintenance manager who was accompanying us during the field inspection pulled out his Apple I-phone and had the neatest App called “Angle Finder”. Set his phone on the beam of the steps and it worked like a charm. To get this FREE app just search the Apple App store for “Angle Finder”. I have a 4GS and it works on mine and the maintenance manager had an iPhone 5. PLEASE BE CAUTIOUS… iPhones are NOT intrinsically safe devices and MUST NEVER be used in HAZARDOUS LOCATIONS (e.g. Class I, II, III locations). You can get the MANUAL angle finder at any hardware store and amazon.com.
