Dropped Objects Calculator

We've added a Drop Zone Calculator to assess the size of the potential danger zone, should a dropped object impact obstructions that cause horizontal deflection of the falling object. An industry standard rule of thumb called the 4:1 rule is commonly used to estimate the drop zone, however obstructions on the way down can significantly alter the horizontal distance that an object can travel. The Drop Zone Calculator aids in decision making by providing the ability to evaluate the potential impact that up to two obstructions can have on the size of the drop zone. It also provides the ability to adjust the 'elasticity' of the object, based on commonly used materials. We hope that this tool will assist in safer workplaces and prevention of significant injuries or events. Feedback or comments are welcome. We've also fixed some minor bugs in the Dropped Objects Calculator, where invalid text entries resulted in a crash.
