Risk Assessments
HAZAN, QRAs and PHAs
Risk assessments and Hazard Analysis (HAZAN) covers a range of techniques which are used to analyse hazards and risks. Typically, this includes analysing the consequences of hazards and the safeguards for hazard prevention and / or mitigation.
The process, facilitated by our consultants, draws on the knowledge and experience of the facility personnel to identify the hazards. These hazards are then ranked in order of importance and the significant risks are further analysed to determine whether further controls are required to be put in place.
Planager conducts quantitative (QRA), qualitative and semi-quantitative risk assessment.
Because of the repetitive nature of the calculations, computer programs are used. Planager runs a number of such computer models including the internationally recognised suite of programs from Dutch TNO (Effects and Riskcurves). A commonly required presentation of the results is as a series of individual risk contours showing the spread of risk within and surrounding the facility. Other presentations are available to meet regulatory and other requirements.
QRA is a powerful tool for helping the decision making process when looking at expenditure of scarce resources for reducing risk, choosing between processes, sites, modes of transport and storage, and looking at sensible separation distances.
