The CJSA process comprises three major steps:
Step 1: identify hazards – identify the set of direct and supporting
construction activities needed for a domain, define their procedures,
and analyze all possible loss-of-control events that may
occur during their execution.
Step 2: assess probability – evaluate the likelihood of occurrence
of each loss-of-control event, the levels of possible intensifying
factors, and the likelihood of use of personal safety gear.
Step 3: assess severity – associate the possible loss-of-control
events with possible accident scenarios, and assess the expected
degree of severity for each type of accident scenario.
