Laser safety in two sided exercises

The use of laser range finders (LRF) in two sided exercises extensively increases the quality of training. Nevertheless, this use was banned due to safety regulations. We have issued a new set of safety orders to allow the use of LRF in two sided exercises. The orders state the use of appropriate safety equipment (glasses) and the restriction of use of magnifying direct view optics. The considerations that lead to this set of safety orders are not trivial. We have required that the risk of an injury would be within the acceptable range. We further required that the added risk due to intent and excess laser use would be negligible. We have compared the risk status of the current training scheme with a well known and acceptable risk. Furthermore, we used the statistical model presented by Sapiens and Steinberg in ILSC 2005 to determine the added risk factor.
