  • Performance Level (PL) Assessment per ISO 13849-1.
Why to conduct risk assessment:
In Canada, Ontario and indeed the entire world, the need to document a formal risk assessment is becoming more important for the following reasons:
  • Regulatory authorities promote the 'Internal Responsibility System'.
  • Regulations are becoming less prescriptive and more performance-based.
  • Passive protection is preferred over active protection, i.e. the safety should be 'built-in' and fail to the safe state. 
  • Higher fines, more expensive lawsuits, loss of reputation, environmental impact and a push for more corporate transparency.
Our Method For Conducting A HAZOP:

A typical HAZOP will consist of the following 14 steps:  

Preparation:
1.    Collect applicable documents and drawings.
2.    Review and understand the process (including one preliminary meeting with client to navigate through the materials).
3.    Break the facility into manageable sections (Nodes).
4.    Prepare a list of Parameter and Operations to be examined.
5.    Prepare the software program for the HAZOP date.

The HAZOP session:
6.    For each Node create Deviations.
7.    List and Record causes for each Deviation.
8.    List and record Consequences for each Cause.
9.    List and record Safeguards or Controls that may prevent either the cause or the consequence.
10.  List any future Actions or recommendations that should be implemented.

Follow Up:
11.  Organize specific questions to ask one expert in particular.
12.  Review legislated requirements (prescribed measures) that were questioned in the HAZOP meeting.
13.  Fill in missing information.

Final:
14.  Provide the output of the software (PHA Pro) in a hardcopy report and Excel file.
