Risk Assessment

Hazard analysis/risk assessments techniques are a means of assessing potential hazards and determining their associated risk. The techniques can be employed to justify safe operation of a facility, to aid in the evaluation and optimisation of the performance of a particular safety system, or to compare the effectiveness of different maintenance regimes / equipment test frequencies. 

Vectra is a recognised specialist in the area of Hazard Analysis and Risk Assessment and is able to provide tailored solutions to complex risk assessment problems.  Vectra’s unique combination of experience in safety and in operations ensures that solutions are comprehensive, but still pragmatic and cost effective.  Particular services available for hazard analysis include:
