About the precautionary zone
When the manager of the projector (operator) cannot prevent spectators from entering the hazard
zone such as in public facilities, it is recommended to secure a space of 1 m or more from the haz-
ard zone as “the precautionary zone” for the safety of the spectators. When installing the projector
overhead, it is recommended that the distance between the floor and the hazard zone be at least
3 m in the vertical direction.
