(A) Worker. A harness and lifeline should be worn by the worker where practical. Where lifelines cannot be used, atmospheric monitoring should be continuous and equipped with automatic warning alarms.
(B) Stand-by person. There should be a trained stand-by person to monitor the worker in the confined space. Duties of the stand-by person should include communications with all workers within the confined space and, if necessary, with the emergency rescue team. Under no circumstances should the stand-by person enter the confined space unless adequate additional assistance is present. Over 60% of confined space deaths, involve would-be rescuers.
(C) Rescue team. A fully charged, positive pressure, self-contained breathing apparatus (SCBA) should be immediately available at the entry point and rescue teams should be equipped with all applicable safety equipment, including lifelines where practical.
