    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).

    For each deviation, the team identifies feasible causes and likely consequences then decides (with confirmation by risk analysis where necessary, e.g., by way of an agreed upon risk matrix) whether the existing safeguards are sufficient, or whether an action or recommendation to install additional safeguards or put in place administrative ...

    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

    Figure A.1 cannot be used for risk assessment. Examples of a risk matrix and a risk decision tree are given in ISO/TR 14121-2. [9] Risk assessment is typically done in at least two cycles, the first to determine the intrinsic risk, and the second to determine the risk reduction achieved by the control measures implemented in the design.
