Dangerous Restart

A dangerous restart occurs when power or energy is applied to a device whose "on / off" switch was in the "on" position when power was applied. NIOSH refers to this hazard as "The uncontrolled Release of Mechanical or Electrical and other Types of Hazardous Energy" (DHHS (NIOSH) Publication No. 99–110 July 1999).

This hazard is currently addressed by OSHA, NFPA and the CSA with mandatory requirements for hazard reduction through large and costly safety devices. (Electrial Standard for Industrial Machinery 2002 Edition)

Due to the cost and size restriction, there are currently no requiremets for this hazard reduction on appliances, small tools and hand held power equipment.
