Qualitative Hazard Analysis
Definition - What does Qualitative Hazard Analysis mean?
A qualitative hazard analysis is a process used to determine the risk and the necessary guidance on the extent to which occupational exposures should be controlled. This is carried out when there are no established occupational exposure limits (OELs).
A qualitative hazard analysis is utilized at the early stage of an occupational project in its life cycle. This form of early-stage hazard analysis is carried out in many industrial plants and other high-risk occupational workplaces to identify hazards, list and analyze them in terms of frequency and consequences. Risks are ranked based on a risk matrix and depending on risk ranking, control measures are proposed and developed.
Safeopedia explains Qualitative Hazard Analysis
A qualitative hazard analysis is a process within the project risk management knowledge area. It is usually performed on all risks, for all projects in workplaces where occupational exposures should be controlled. A qualitative hazard analysis identifies all project risks based on a pre-defined rating scale. Risks are then assigned a quantitative value based on their probability or likelihood of occurring and the impact on project objectives in the event that they occur.
A qualitative hazard analysis features the appropriate categorization of the risks, either source-based or effect-based for accurate assessment and management of hazards associated with chemical exposures in the workplace.
