Operators must make sure their plant does not run into pedestrians or other powered mobile plant. Where a collision is possible, such as where plant works near ground crews or other plant, whoever manages or controls the plant must see that it carries a warning device, for example a reversing alarm or revolving light, to alert people at risk from its movement.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
