Lecturer: Dr Sean Reidy
Question 1
In compliance to the SHWW Act 2005, it is the duty of the employer (section 8) to prepare a risk assessment as required by section 19 of the Act. It states that every employer must identify the hazards at the workplace, assess the risks from those hazards, and have a written risk assessment of those risks.
Examples of three Risk Assessment Techniques includes:
1. Hazard & Operability studies (HAZOP)
Hazard and Operability (HAZOP) studies is a qualitative risk analysis technique that is used to identify weaknesses and hazards in a processing facility. It is normally used in the planning phase (design).
This technique was developed in the early 1970s by imperial chemical industries Ltd. It has gained wide acceptance in process industries as an effective tool for plant safety & operational improvements. For example, it is widely used in Norway in the oil & gas industry.
This technique involves the application of a formal systematic critical examination of the process and engineering intentions of new or existing facilities. It assesses the hazard potential that arises from deviation in design specifications and the consequential effects on the facilities as a whole. This technique is usually preformed using a set of guide words: NO/NOT, MORE/LESS OF, AS WELL AS, PART OF, REVERSE, AND OTHER THAN.
From these guidewords, scenarios that may result in a hazard or an operational problem are identified. For example, when analysing a pipe from one unit to another in a process plant, it is defined the deviation “no throughput” based on the guideword NO/NOT, and the deviation “higher pressure than the design pressure” based on the guideword MORE OF. As a result the causes and consequences of the deviation are studied. This is done by asking
