For a guard to be safe, openings must be narrow enough to prevent a finger, hand or arm from reaching far enough to be caught or severed by a moving part, such as a motor, belt or gear.

The SECURIMETRE is a simple tool, available from different organizations, that ensures that the dimensions of an opening in a guard comply with the safety standards in force for the machinery in question. You don't have the SECURIMETRE? You can buy it from various organizations or you can use your own measuring tape. This app simplifies the calculation and interpretation of results according to the different standards in effect.
