Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
The risk rating of the hazard with the control in place is known as the 'residual' risk rating. Risk, within the occupational health and safety sphere, is defined as the 'effect of uncertainties on objectives [8] '. In the context of rating a risk, it is the correlation of 'likelihood' and 'consequence', where likelihood is a quantitative ...
LOPA is a risk assessment undertaken on a 'one cause–one consequence' pair. The steps of a LOPA risk assessment are: [4] Identify the consequences, using a risk matrix; Define the risk tolerance criteria (RTC), based on the tolerable/intolerable regions on the risk matrix; Define the relevant accident scenario, e.g. mechanical or human failure
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] [2] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [3]

Risk Rating 2.0 considers a host of variables that weren’t included in the previous NFIP model. According to FEMA, these factors are flood frequency, flood types, proximity to potential flood ...
That unmitigated risk is then compared against a tolerable risk target. The difference between the unmitigated risk and the tolerable risk, if the unmitigated risk is higher than tolerable, must be addressed through risk reduction of provided by the SIF. This amount of required risk reduction is correlated with the SIL target.
An occupational safety management system (OSMS) is a management system designed to manage occupational safety and health risks in the workplace.If the system contains elements of management of longer-term health impacts and occupational disease, it may be referred to as a occupational safety and health management system (OSHMS) or occupational health and safety management system (OHSMS).
