:pencil2:Analysing Hazard
Hazard analysis -
used in the workplace to identify potential hazards, with the obj of preventing accidents.
ROOT CAUSE ANALYSIS
suitable when an accident occurred with many
potential causes
provides a step-by-step method for determining the root
cause based on the chronology of events
3root causes analysis process
Direct Cause
Energy sources + Hazardous Materials
Indirect Cause
Unsafe act + unsafe condition
Basic Cause
Policies&Procedure + Personal factors + Environmental factors
5 phases in the root cause analysis process

CHANGE ANALYSIS
used in problem solving and in determining the cause of
accidents
comparing a situation that does not exhibit a
problem to one that does
7 steps in change analysis
:red_flag:Establish the norm
:red_flag:Identify, locate + describe the change
:red_flag:Defined the prob
:red_flag:Specify what was + what was not affected
:red_flag:Identify the distinctive features of change
:red_flag:List the possible cause
:red_flag:Selet the most likely causes
a summary is prepared by answering the 5Ws (what, where,
who, why and when) and 1H (how) to a problem
suitable to determine the root cause for a simple situation and it is not thorough enough for more complex situations.
JOB HAZARD ANALYSIS
the most effective method in analysing workplace hazards where work processes are analysed in detail to ensure that all work processes and activities are safe
steps and components of job hazard analysis
