Risk Assessment involves considering what could happen if someone is exposed to a hazard and the likelihood of it happening. We can use varying study types, from a simple qualitative or semi-quantitative method of risk assessment called Risk Ranking, up through a fully-quantitative risk analysis—QRA. We also provide risk-based design assistance through various applications of risk analysis and risk assessment.
A risk assessment can help determine:
- how severe a risk is
- whether any existing control measures are effective
- what action you should take to control the risk
- how urgently the action needs to be taken.
Synergy Global Solutions supports Organizations to formally establish processes to identify hazards, assess the risks involved in all aspects, manage until the risks are eliminated, reduced or controlled up to a level being acceptable.
Process Hazard Analysis (PHA) studies are the foundation for process safety and risk management programs. PHA is a rigorous and systematic approach to identifying, evaluating, and controlling the hazards of processes involving fires, explosions, releases of toxic or flammable chemicals and major spills of hazardous chemicals, and it focuses on equipment, instrumentation, utilities, human actions, and external factors that might impact the process.
A risk analysis for hazardous processes should be conducted for each stage of design, operation, and shut down. PHAs are required to be completed initially and revalidated every five years – however, major changes made to a process warrant a total re-do to be conducted earlier. Furthermore, when either temporary or permanent modifications are made to a hazardous process, a Management of Change (MOC) PHA should be utilized to evaluate the inherent hazards that can result from the change.
PHA is required by process safety and risk management regulations around the world. It is good engineering practice. Companies that handle or process highly hazardous chemicals have a responsibility to protect employees, the public and the environment from exposure to accidental releases.PHA also helps to protect against process downtime, property damage, product quality issues, and adverse publicity from accidents. The financial cost of catastrophic accidents is exceptionally high and PHA can be considered an inexpensive form of insurance.
Synergy has pioneered and continues to develop new and improved approaches for performing and conducting PHA studies over a period of 30 years. These approaches allow studies to be performed efficiently and effectively and help to ensure study quality. Protecting lives, assets, and the environment depends on the quality of PHA studies and studies must be performed properly. Our facilitators have extensive experience in performing Layer OF Protection Analysis (LOPA) in support of other PHA methods, standalone, or to determine SIL targets for safety functions.
The process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process. The selection of a methodology to use depends on many factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the process before, and if the process is unique, or industrially common.
