-==Types of threat for functional objects==
-A threat is a source of potential harm <ref>"''An indication of possible violence, harm, or danger.''": DHS (2004): National Response Plan. Department of Homeland Security: Washington. Online: http://www.scd.hawaii.gov/documents/nrp.pdf [2011-03-23].</ref>. It includes [[security]] threats which originate in wilful act ([[human intent]], such as the threat of violence or [[Urban terrorism|terrorism]]), and [[Safety|safety threats]], which originate in non-intentional circumstances (such as the threat of [[Natural threat|natural hazards]], e.g. floodings, volcanic eruptions etc., or man-made hazards, e.g. industrial accidents or [[technical failure|technical failure]], [[human failure]]).
-When we look at the concept of threat from the perspective of its functional use (which we can also do for urban objects), a threat can be defined as any circumstance that threatens the continuity or quality of those [[function|functions]] (which include, amongst others, protection of life and economic use).
-Threats can in this perspective be classified by their origin. This classification is layered: the first layer discriminates between internal threats that have impact on the internal processes (such as a car hitting a building and causing diminished structural safety for the inhabitants) and external threats that only have impact on external requirements for those processes (such as a discontinuation of electricity supply to a building). Both types of threats will result in diminished continuity or quality of functions provided by the building (reduced safety in the first example, reduced comfort in the second example).
-Within internal threats we can distinguish threats that originate from [[natural threat|natural]] processes, threats that originate from failures, and threats that originate in [[human intent|wilful acts]]. Within threats that originate from failure, we can again distinguish between failures of designs ([[technical failure]]) and failures of human action ([[human failure]]). This structure is graphically depicted in the (clickable) figure below.

 '''Safety''' is the degree of protection of persons or objects against non-deliberate sources of [[risk]]. The equivalent term used for deliberate sources of risk, is [[security]].
+==Distinction between safety and security==
+The distinction between [[safety]] and [[security]] lies in the type of threat that is at the source of the risk. While security concerns risk due to [[human intent]] (wilful harmful acts), safety concerns all other risk. Shortly put, safety concerns protection from ''accidents'', security concerns protection from ''crime''.
+This means that whether a measure is a security measure or a safety measure, depends on the type of risk it is ''meant'' to mitigate. A reinforced window for example can be both:
+*When installed to prevent harm coming to the inhabitants coming from a gas tank accidentally exploding, it would be a safety measure.
+*When installed to protect the inhabitants from terrorist explosions, it would be a security measure.
+A measure can also serve as a security and a safety measure at the same time. An example can be found in a door: the fire-delaying properties of the door might serve as a safety measure while the fact that it is protecting against unauthorised entry is a security measure.
