Parker Hannifin: Safe Stopping Distance with Safety Exhaust Valves
Safe Distance in Machine Design When machine safeguarding is used one of the most relevant (and least discussed) effective measures is safe placement of the equipment in relation to the hazard. This is especially true when trying to comply with the requirements to eliminate trapped energy under ISO 13849-1 where exhaust time and volume of compressed air in the machine play a role in creating a safe condition.
