Hazard Analysis (HAZAN) is simply the application of numerical methods to obtain an understanding of hazards in terms of : How often a hazard will manifest itself, and with what consequences for people, process and plant.
HAZAN is therefore the essential prerequisite for the complete risk assessment process, i.e. first analyze the hazards and then go on to assess the risks they present and determine what, if any, ameliorating measures should be taken.
Identifying the Hazards
For the hazard analysis to be complete it is essential that all the hazards present in the defined system have been identified. Quantitative data based on our past experience are the most important means of identifying hazards and assessing potential frequency, although for new processes and techniques, experimental data may be limited.
Our auditors consider past experience and near misses and procedures for dealing with emergencies and abnormal events, and identify hazards effectively and produce a useful future record.
Our experts use methods such as the Dow Index and Mond Index, for systematically identifying hazards and rank its priorities. The thoroughly conducted hazard analysis provides a sound quantitative basis for decision on ameliorative measures that it will be reasonable to take.
