Safety is the state of being "safe" (from French sauf), 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 economical losses. It can include protection of people or of possessions.
There are two slightly different meanings of safety. For example, ...view middle of the document...
Using this definition, protection from a home’s external threats and protection from its internal structural and equipment failures (see Meanings, above) are not two types of safety but rather two aspects of a home’s steady state.
In the world of everyday affairs, not all goes as planned. Some entity’s steady state is challenged. This is where security science, which is of more recent date, enters. Drawing from the definition of safety, then:
Security is the process or means, physical or human, of delaying, preventing, and otherwise protecting against external or internal, defects, dangers, loss, criminals, and other individuals or actions that threaten, hinder or destroy an organization’s “steady state,” and deprive it of its intended purpose for being.
Safety can be limited in relation to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization. It is used in order to ensure that the object or organization will do only what it is meant to do.It is important to realize that safety is relative. Eliminating all risk, if even possible, would be extremely difficult and very expensive. A safe situation is one where risks of injury or property damage are low and manageable.
Types of safety
It is important to distinguish between products that meet standards, that are safe, and those that merely feel safe. The highway safety community uses these terms:
Normative safety is achieved when a product or design meets applicable standards and practices for design and construction or manufacture, regardless of the product's actual safety history.
Substantive or objective safety occurs when the real-world safety history is favorable, whether or not standards are met.
Perceived or subjective safety...
