Risk:
An estimate of the probability of a hazard‐related incident or exposure occurring and the severity of harm or damage that could result. (ANSI/ASSP Z590.3‐2011(R2016))
Effect of uncertainty on objectives. (ANSI/ASSP/ISO 31000‐2018)
Effect of uncertainty. Note 4 to entry: Risk is often expressed in terms of a combination of the consequences of an event (including changes in circumstances) and the associated “likelihood” (as defined in ISO Guide 73:3009, 3.6.1.1) of occurrence. (ANSI/ASSP/ISO 45001‐2018)
An estimate of the combination of the likelihood of an occurrence of a hazardous event or exposure(s), and the severity of injury or illness that may be caused by the event or exposures. (ANSI/ASSP Z10.0‐2019)
A combination of the probability of occurrence of harm and the severity of that harm. (ANSI B11.0‐2020)
A combination of the likelihood of occurrence of injury or damage to health and the severity of injury or damage to health that results from a hazard. (NFPA 70E‐2018)
A combination of the severity of the mishap and the probability that the mishap will occur. (MIL‐STD‐882E‐2012)
Risk Acceptance:
Informed decision to take a particular risk. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Analysis:
Process to comprehend the nature of risk and to determine the level of risk. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Assessment:
A process that commences with hazard identification and analysis, through which the probable severity of harm or damage is established, followed by an estimate of the probability of the incident or exposure occurring, and concluding with a statement of risk. (ANSI/ASSP Z590.3‐2011(R2016))
Overall process of risk identification, risk analysis, and risk evaluation. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Process(es) used to evaluate the level of risk associated with hazards and system issues. (ANSI/ASSP Z10.0‐2019)
The process by which the intended use of the machine, the tasks and hazards, and the level of risk are determined. (ANSI B11.0‐2020)
An overall process that identifies hazards, estimates the likelihood of occurrence of injury or damage to health, estimates the potential severity of injury or damage to health, and determines if protective measures are required. (NFPA 70E‐2018)
The scientific process that characterizes the nature and magnitude of health risks to humans and ecological receptors from chemical contaminants and other stressors that may be present in the environment. (Environmental Protection Agency)
Risk Avoidance:
Informed decision not to be involved in, or to withdraw from, an activity in order not to be exposed to a particular risk. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Centric
The state when an organization gains a sense of urgency around a fatal or serious injury/illness‐level risk as an actual catastrophic event; seeing risk of harm as actual harm itself resulting in the action of mitigating risk in advance of mishaps. (Walline 2014)
The mindset of acting upon risk rather than hazards. (Authors)
Risk Criteria:
Terms of reference against which the significance of a risk is evaluated. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Description:
Structured statement of risk usually containing four elements: sources, events, causes, and consequences. (ANSI/ASSP/ISO 31010‐2019)
Risk Driver:
Factor that has a major influence on risk. (ANSI/ASSP/ISO 31010‐2019)
Risk Evaluation:
Process of comparing the results of risk analysis with risk criteria to determine whether the risk and/or its magnitude is acceptable or tolerable. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Factor:
A component of risk derived from an identified hazard used to estimate and measure a risk level. The primary risk factors used in risk assessments are severity of consequence (S), and likelihood (L) or probability (P) of occurrence. Other risk factors used include exposure (E), frequency of exposure (F), detection of failure (D), control reliability (CR), and prevention effectiveness (PE). (Authors)
Risk Identification:
Process of finding, recognizing, and describing risks. (ISO Guide 73/ANSI/ASSP Z690.1‐2011)
Risk Level:
The characterization of risk as either High, Serious, Medium, or Low. (MIL‐STD‐882E‐2012)
Risk Management:
Coordinated activities to direct and control an organization with regard to risk. (ANSI/ASSP/ISO 31000‐2018)
