How do you ensure that your emergency stop buttons will work when needed? The emergency stop is the last line of defense and a good article by Robin J Craver mentions the following:
"The nature and operation of the machine must be considered.
· Is it safe to have the emergency stop system cut the power to the machine drives and actuators? This may result in the hazard “free falling” leading to a more dangerous situation.
· Should the system actuate a brake or clamp?
· Would stopping the machine in position result in a worsening of an injury?
· Should the system allow the machine to continue on or reverse to a safe position?"
