Risk is the probability that exposure to a hazard will lead to a negative consequence, or more simply, a hazard poses no risk if there is no exposure to that hazard. Risk is a combination of hazard, exposure and vulnerability. [11] For example in terms of water security: examples of hazards are droughts, floods and decline in water quality. Bad ...
A chemical hazard symbol is a pictogram applied to containers and storage areas of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for transportation, containers for end-use, or on a vehicle during transportation.
R-phrases (short for risk phrases) are defined in Annex III of European Union Directive 67/548/EEC: Nature of special risks attributed to dangerous substances and preparations. The list was consolidated and republished in Directive 2001/59/EC, [ 1 ] where translations into other EU languages may be found.
When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.
The outcome is the harm that results from an uncontrolled hazard. A risk is a combination of the probability that a particular outcome may occur and the severity of the harm involved. [108] "Hazard", "risk", and "outcome" are used in other fields to describe e.g., environmental damage or damage to equipment.

Risk control, also known as hazard control, is a part of the risk management process in which methods for neutralising or reduction of identified risks are implemented. Controlled risks remain potential threats, but the probability of an associated incident or the consequences thereof have been significantly reduced.
Hazard control methods at the top of the graphic are potentially more effective and protective than those at the bottom. Following this hierarchy of controls normally leads to the implementation of inherently safer systems, where the risk of illness or injury has been substantially reduced.
