Introduction of safety 

Safety certification is a passport for market access. Application of a safety standard is intended to reduce the likelihood of pain, injury and, in the case of fire. A product safety standard that classifies energy sources, prescribes safeguards against those energy sources, and provides guidance on the application of, and requirements for, those safeguards.

An energy source that causes pain or injury does so through the transfer of some form of energy to or from a body part. 


Forms of energy 

Electrical energy 

Thermal energy 

Chemical reaction 

Kinetic energy 

Thermal energy 

Radiated energy 

Examples of body response related to energy sources 


Many products necessarily use energy capable of causing pain or injury. Product design cannot eliminate such energy use. Consequently, such products should use a scheme that reduces the likelihood of such energy being transferred to a body part. The scheme that reduces the likelihood of energy transfer to a body part is a safeguard. Safety provide designers with basis of requirements of these safeguards.
