Risk Assessment

Peer Risk Assessment:

When the Risk Assessment process begins, Sentinel Machine Safety and the client will collaborate to form a Peer Risk Assessment Team. This group is established in order to provide a multi-discipline team that can view each potential risk and mitigation from several angles in order to provide a solution that works to the benefit of each party involved. Mitigations that are too cumbersome can impede work flow, and it is important that this team includes members of the Operator staff as well. The intended list includes at least one member of each group, as follows:

  • Sentinel Machine Safety Analyst
  • Plant Manager or Project Manager
  • Operator staff
  • Maintenance staff
  • Plant Safety Manager
  • Plant Engineer, if available

The First phase of the Risk Assessment process will be conducted with the assistance of the OEMs and the client in order to establish each individual potential risk area in the production line. Visits or meetings with the OEM may be required in order to obtain all of the necessary information in order to assess the manufacturing line. Machine drawings and maps will be consulted in order to obtain the clearest picture of the line possible without physically observing an existing line. The Peer Risk Assessment Team will then assign a SIL (Safety Integrity Level) rating to each hazard to clearly label its severity. Below: An example of an initial scoring section from a Risk Assessment. Once the hazards have been discussed and mitigations have been suggested and developed to reduce risk, the second phase of the Risk Assessment can begin.

An explanation of SIL scoring:
When performing a Risk Estimation in order to define a SIL level, four factors are used. The Severity of the possible harm (S), the Frequency and Duration of Exposure (F), the Probability of Occurrence of a hazardous event (P) and the probability of Avoiding or Limiting harm (A). These four factors are assigned a numerical value, and a calculation is performed to determine the final SIL score. The lower the assigned number, the less risk is associated with a hazard. Scores range from 0 (or OM, which stands for Other Measures, in some cases) up to 3, with the majority of risks falling somewhere in the middle of the scale.
