Fire Hazard Analysis

A Fire Hazard Analysis (FHA) is a method of evaluating the fire hazards and hence consequences which could potentially occur in a facility. Commonly in the process industry the term FHA is used interchangeably with FRA (Fire Risk Assessment) which also analyses the probability of events occurring, not just the consequences of the hazard. This is then incorporated into the overall risk envelope for a facility, but typically the recommendations are high level and leave a lot to interpretation.

With Micropack’s experience we can carry out both FHA and FRA and provide specific recommendations for improvement if required which give operators peace of mind in moving projects forward.

After review of the potential hazards either on an existing site or at FEED stage of a project, an analysis is conducted to ascertain the likelihood of fire events in terms of release frequencies, release rates, fire sizes and ignition event frequencies. The outcomes of this analysis are assessed for existing hydrocarbon/ high escalation events and then the impact is analysed with respect to tolerable risk levels/ recommendations to ensure risk acceptable.

Micropack utilise a wide range of tools during FHA/ FRA which include dispersion/ consequence models, CFD models, detection mapping tools, and fire protection tools including Pipenet to analyse the adequacy of any existing detection and protection measures.
