After the speed demonstration of the pto shaft, the reaction timer can be used by individuals in the audience. Readings are obtained and then compared to the readings with the hundredths of seconds listed on the chart and the distance traveled in that length of time. A last intent is to show the need for shaft shielding . By removing one end of the shaft using the sliding collar, the actual shaft itself can be viewed. The rectangular solid and tube shafts can be pointed out to , and related to slides or pictures illustrating actual unprotected shafts in use.
Discussion can follow about unprotected shaft edges and the increased hazard they represent.
Targeting information to the specific audience is necessary, but the demonstration has its applications in each. For the purposes of the demonstration, however, the practical situation necessarily reaches from when the situation is first comprehended to the time action is taken. This reinforces the fact that in most situations are not seen until too late. Thanks to Dr. Kathyrn Campbell for the advice and reference. The main intent of the grain auger hazard demonstration is to present how a grain auger actually works.
