Basic Calculation Examples When installing a safety light curtain or other electrical detection protective device, refer to the minimum required distances for stopping the machine prior to the body reaching the hazardous zone when the body enters the detection zone. These distances are defined in standards such as ISO When installing a light curtain, be sure to provide the safety distance minimum distance determined by sources such as the standards, regulations, and laws of the country or area in which the light curtain will be used. If S is greater than or equal to mm

This post explains how to calculate safety distance for light curtains. Then, once installed, use a stop time measurement STM device to calculate how quickly the machine stops, and use this value to determine the minimum safety distance required. Taking the time to calculate safety distances upfront not only ensures compliance with global safety regulations, but also helps prevent long term costs of injury and machine downtime.
Safety Light Curtains Calculating Safety Distance When installing safety light curtains, a minimum safe distance that the light curtain can be mounted from the point of hazard must be calculated. The distance between the hazard and the light curtain must be such that the time it takes the operator to reach the hazard with respect to approach speeds of parts of the human body is greater than the stopping time of the machine. In the United States there are two formulas that are used to properly calculate the safety distance. The first, the OSHA formula, is the minimum requirement for the calculation of the safety distance.
