: Required distances depend on the shape and size of the opening (slot, square, or round). Slot Openings : If the slot width is is greater than 180 Square/Round Openings is greater than 240
To understand what the contains, here are the most critical tables: en iso 13857 safety distances pdf
In the world of machinery safety, few concepts are as fundamental yet as frequently misunderstood as "safety distances." Every year, accidents occur in industrial settings not because a guard was missing, but because it was placed too close to the hazard zone. A guard that prevents a hand from reaching a blade is useless if the hand can reach the blade before the machine stops. : Required distances depend on the shape and
If a person reaches over a fence or wall, the required distance depends on the height of the hazard ( ) and the height of the protective structure ( Height of Hazard ( Structure Height 1.0m Structure Height 1.4m Structure Height 1.8m Structure Height 2.2m 2.0m 1.6m 1.0m 2. Reaching Through Openings Distances are determined by the shape and size ( ) of the opening (slot, square, or round). Finger Tip: For an opening , the distance must be Finger: For an opening , the distance must be Arm: For an opening , the distance must be 🧬 Geometric Logic If a person reaches over a fence or
In the world of machinery design and workplace safety, a gap of just a few centimeters can mean the difference between a routine operation and a life-changing injury. Every year, workers lose fingers, hands, or arms because they reach past inadequate guards or through openings that are just slightly too large.
At the heart of EN ISO 13857 lies the concept of . This is the scientific study of the measurements and proportions of the human body. The standard uses data representing the 95th to 99th percentile of the population. This means that the calculations are designed to protect the vast majority of people—specifically, taller individuals with longer arms and larger hands.
The goal of EN ISO 13857 is to establish clear values for safety distances that prevent people from contacting dangerous machine parts. It specifically addresses:
