HAZOP Studies
The key elements in process hazard
management are hazard identification and risk assessment and
control. Midland Engineering Limited is prepared and qualified
to provide assistance in hazard identification and in risk
assessment and control. We are also prepared to assist in
assuring that the public is involved in safety and
environmental issues.
Some of the techniques used in hazard identification include:
- Fire and Explosion Index (F&EI)
- Chemical and Exposure Index
- ''What If" analysis
- Checklists
- Hazard and Operability Studies (HAZOP)
Risk assessment and control takes place after hazard
identification. It consists of:
- Risk identification
- Risk estimation
- Analysis of alternatives
- Hazard and risk reduction
- Acceptance of risk or reanalysis or elimination of the
process if the risk is not acceptable
Risk assessment techniques include:
- Preliminary risk screening
- Expert opinion
- Fault tree
- Failure mode and effective analysis (MFEA)
- Consequence analysis
- Quantitative risk assessment
The Community Awareness and Emergency Response (CAER)
process of the Chemical Manufacturers Association's
Responsible CARE Program is used, along
with local emergency planning groups, to ensure that public
comments and concerns are considered in design and
implementation of the facility's process safety systems.
These processes can be adapted to both large plants and small
plants with limited resources. It has been found from much
experience that not only is safety performance enhanced, but
cost savings through increased yields and productivity have
also resulted. |
