This unit is for the entry controller/top person who controls entry and arrangements for confined spaces without entering them. It includes the duties of an entry controller, pre-entry procedures, entry into and exit from the confined space, maintaining communications and initiating and controlling emergency procedures.
Please note: the 6160-04 qualification is often combined with 6160-03 qualification, which can reduce the duration of the training to 1 day. So, taking the more popular 6160-03 course and then adding the 6160-04 provides two (2) qualifications over 4 days. Splitting these courses out is a 6 day course. Thus, the recommendation to combine the two together (where possible).
