Risk Assessment

QRA

We are expert in the application of risk analysis and assessment methodologies, ranging from qualitative techniques through to fully quantified approaches.

Fully detailed Quantified Risk Assessment (QRA) is a central part of the work we do. Our expert team are well versed in the assessment and calculations required to evaluate the risk profile of an establishment. This includes both the assessment of safety risk to people and the environmental risk to surrounding receptors. We are experienced in performing risk calculations to determine scenario risk, the overall site risk and individual risk posed to respective worker roles We can meet your requirements on risk presentation including the development of an FN curve for the facility.

We will translate the output of the QRA to communicate your risk picture in a straightforward and concise way. Giving you the clarity to make informed risk based decisions without diving into the complexity of the numbers.

Occupied Buildings Risk Assessment

We have experience in performing Occupied Buildings Risk Assessment (OBRA) for both new developments and existing facilities.

An OBRA evaluates the major accident hazard risks posed to people while they are located in buildings. Depending on the nature of the hazards, buildings may be impacted by fires, explosions, or toxic releases. By assessing the potential impact and considering the construction of the building, the level of harm to which building occupants would be exposed can be determined.

The results of the OBRA can determine whether the risk to a building’s occupants is tolerable and, ultimately, whether the buildings on a site are providing suitable protection for the people working in them.

For new developments, an OBRA may include consideration of different building locations and plant layout, to determine the best choice from a risk perspective and minimise the risk posed to people. The earlier in the project timeline that building sitting is considered the better.

Hazardous Area Classification 

Schedule

We utilise relevant British Standards (BS EN 60079 series) and other industry guidance including EI 15, flammable mist research and industry specific guidance (such as IGEM, Liquid Fuels UK etc) to determine hazardous areas. Schedules are produced by reviewing documentation such as drawings and safety data sheets in combination with walking around the site to capture all potential release points.  The schedule will detail the nature and shape of the hazardous area which will allow for drawings to be produced and equipment to be appropriately selected.

Drawings

Hazardous area drawings can be produced utilising the information described within the hazardous area schedule that show the extent and type of zone at each location.  In addition to layouts, side views can also be produced to show additional relevant detail where required.
