Confined Space Entry

Confined Space Entry

Before entering a confined space, workers need to be properly trained on entry procedures and in the proper use of equipment. Workers should always have a standby person, or Hole Watch, posted outside the hole who remains in direct communication with the workers inside. For more detailed information on confined entry space procedures, check out API WorkSafe training and relevant API safety standards.
