It is the state of being "safe", the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable.
Safety can also be defined to be the control of recognized hazards to achieve an acceptable level of risk. This can take the form of being protected from the event or from exposure to something that causes health or economic losses. It can include protection of people or of possessions.
In risk assessment, safety often is conceived as a set of measures and activities for ensuring the security and sustainable development of assets. It is a quantitative concept that is measurable by safety performance indicators, which are quantities that measures level of safety in a given subsystem/system.
