Machine Guarding
Winches and Cables
Nip points are created by a cable being wrapped on a drum. Areas where employees may come in contact with the cable should be protected with a guard that only allows room for the cable to enter.
Level wind devices for hoist winches should have a handle that prevents the operator from placing his hand directly on the cable. Sheave guards on the crown block and traveling block should be inspected for abnormal wear and secure attachment to prevent dropped objects.
Labeling and Signs
Equipment that starts automatically or is controlled remotely should have a sign clearly visible that identifies how the equipment is energized. Warning signs should be posted to ensure employees follow proper energy isolation protocol when servicing equipment.
Exclusion Zones
Areas that cannot be effectively guarded should be closed off as an exclusion zone while in operation. For example, under the rotary table during drilling operations and around automated pipe handling systems.
