Process Hazard Analysis (PHA)

Most industries work with potentially hazardous materials, either  in the form of gases, liquids or dust.  Knowing how these materials are potentially harmful to human health, the environment and even business, it is an obligation for companies working with such materials to identify and evaluate the dangers involved to control or mitigate potential hazards by implementing the right safety measures.

If properly conducted, the risk relating to human health, process downtime, property damage and product quality issues caused by equipment failures, human errors or even external events can be reduced significantly.

Our consultants have years of experience in process hazard analysis and can assist you at all stages of your engineering and management control process, from concept design, process development, facility safe operation, initial hazard evaluation to continued safe operability of your facility.

HAZID (Hazard Identification)

HAZID (Hazard Identification) is a risk analysis technique for early identification of hazards performed at the earliest possible stage of project development.

Through HAZID, Gexcon can help you identify potential hazards in your facility and reduce the likelihood and severity of credible events associated with those hazards that might have a catastrophic impact on your employees, business, and the environment. Identifying high risk scenarios at an early stage of the project development can significantly reduce the cost of implementing measures suitable to reduce the risk to an acceptable level.

HAZOP (Hazard and Operability Studies)

A HAZOP (Hazard and Operability Study) is a structured form of Hazard Assessment which can form the first step of the Hazard and Risk Assessment Life Cycle. The purpose of the HAZOP study is to verify and test that the control and operation of your facility is robust and inherently safe so far as is reasonably practicable, by identifying credible deviations from normal operation, assessing their potential consequences and safeguards which are in place to mitigate the associated risk with these scenarios.

Through HAZOP, Gexcon can identify where there may be hazard or operability issues and make recommendations of potential measures to address these. In some instances, these recommendations may require the project team to design a suitable engineering solution.

CHAZOP (Control Systems HAZOP)

Unlike HAZOP, which looks at the entire facility, mechanical equipment and processes, CHAZOP (Control Systems Hazard and Operability Study) focuses on the potential hazards associated with the control system and individual failures of the processes.

Through CHAZOP, Gexcon can assist in identifying the hazards related to the operability of the control system and investigate the control systems suitability.

FMEA (Failure Mode and Effects Analysis)

FMEA (Failure Mode and Effects Analysis) allows organisations to anticipate, identify and detect potential points of failure of design or manufacturing processes and analyse the effects of potential consequences occurring as a result of those failures.

BowTie Analysis

BowTie Diagrams are used to represent the relationship between potential causes, consequences and controls associated with undesired hazardous events, together with the barriers in place for preventing those from being realized. The methodology is formed by the relationship between Hazards, Top Events, Threats and Consequences and is designed to provide a more functional overview to visualize credible paths from threats to high consequence scenarios.

 

What-If?

What-If? is a workshop-based process hazard analysis form which investigates the potential consequences of foreseeable process upsets and the safeguards in place to mitigate the risk of these scenarios. The effectiveness of this hazard analysis method relies heavily on the experience of the workshop team to ensure that relevant foreseeable scenarios are captured.
