2.8Setting-up the safety fence or enclosure

2.9Positioning of rope or chain

A safety fence or enclosure should be set up so that no one can easily enter the robot's restricted space. If it is impossible, utilize other protectors as described in Section 2.9.

(1)The fence or enclosure should be constructed so that it cannot be easily moved or removed.

(2)The fence or enclosure should be constructed so that it cannot be easily damaged or deformed through external force.

(3)Establish the exit/entrance to the fence or enclosure. Construct the fence or enclosure so that no one can easily get past it by climbing over the fence or enclosure.

(4)The fence or enclosure should be constructed to ensure that it is not possible for hands or any other parts of the body to get through it.

(5)Take any one of the following protections for the entrance/ exit of the fence or enclosure:

1)Place a door, rope or chain across the entrance/exit of the fence or enclosure, and fit it with an interlock that ensures the emergency stop device operates automatically if it is opened or removed.

2)Post a warning notice at the entrance/exit of the fence or enclosure stating "In operation--Entry forbidden" or "Work in progress--Do not operate" and ensure that workers follow these instructions at all times.

When making a test run, before setting up the fence or enclosure, place an overseer in a position outside the robot’s restricted space and one in which he/she can see all of the robot’s movements. The overseer should prevent workers from entering the robot's restricted space and be devoted solely to that task.

If it is not possible to set up the safety fence or enclosure described in Section 2.8, hang a rope or chain around the perimeter of the robot’s restricted space to ensure that no one can enter the restricted space.

(1)Ensure the support posts cannot be moved easily.

(2)Ensure that the rope or chain’s color or material can easily be discerned from the surrounds.

(3)Post a warning notice in a position where it is easy to see stating "In operation--Entry forbidden" or "Work in progress --Do not operate" and ensure that workers follow these instructions at all times.

(4)Set the exit/entrance, and follow the instructions given in Section 2.8, (3) through (5).
