| Safety
and risk The term of safety is defined in the industrial standard DIN 31004. Safety is closely related to the term risk. Risk consists of the eventuallity of a damage and the extend of this damage . During the state of safety the risk is smaller than the still justifiable risk. Absolute safety without any risk does not exist neither in technology nor in nature. Protection Protection is the risk decreasing through taking steps which either minimize the occurence probability or extend of damage, ideally both. Due to the vast number of different bullets and calibers, the number of threats is endless and therefore absolute protection is impossible. Threat levels That is why body armor offer a limited protection performance. For easier handling of threat and appropriate protection, so called threat levels were defined. Since the threats vary significantly with geographic location, the threat levels show country specific modifications.  Due to different types of ammunition with different hardness and weight, as well as varying bullet velocities and energy, the country specific threat levels are hardly to compare with each other. Therefore the following table should be rated more as an overview than a comparison.
