Escape Release Key Features




Heavy duty escape release provides the “possibility to release manually without aids the guard locking from inside the safeguarded area to leave the area” – EN ISO 14119





TUV Certification








Selecting your Heavy Duty Escape Release


An Escape Release requires the following conditions to be met;




Deliberate unlocking of the guard locking from inside of the safeguarded area […] without auxiliary means […]”   EN ISO 14119



The interlock must be designed such that no mechanism will impede operation of the escape release to egress a safeguarded space.

Operation of the Escape Release





“[…] unlocking means shall be ManuallyOperated and act directly on the […] locking mechanism”   EN ISO 14119



The escape release will override any locking mechanism or trapped key sequence designed within a heavy duty interlock.






“[…] Unlocking shall Generate a Stop Command”   EN ISO 14119



Escape Release must always be used in conjunction with a form of safe-monitoring. In the image below, both forms of escape release (single action handle and integrated module) must be used in conjunction with a form of monitoring.



Monitoring and Safety for the Escape Release




“Unlocking means […] shall only be accessible from inside the safeguarded space”   EN ISO 14119



Design of the access point should be such that operation of the escape release must not be possible from outside the safeguarded space.








Why use the Heavy Duty Escape Release






Where operators are performing Whole Body Access, measures should be provided in the event of unexpected start up or restart of hazardous machinery to egress from the hazardous space.



Manual reset to restart hazardous machinery is typically done from a location with a good view of the safeguarded space. In the application pictured below, low visibility makes it almost impossible to anyone performing this reset to guarantee if users are inside behind obstacles. If the machinery restarts and someone is inside the safeguarded space, they need a means to escape to safety.

Heavy Duty Escape Release Reset Options




Automatic Reset

Automatic reset occurs as soon as the handle of the escape release is pulled back to it’s ‘un-actuated‘ position; i.e. returned to its original position.




Push Reset


Instant reset of an escape release can be achieved but pressing the button on the front of the escape release module from outside the protected area.





Auxiliary Reset

Effective monitoring of escape release use can be achieved with an auxiliary reset (in this case via a key). The key forces a procedure to occur in order for the reset to take place. The key must be inserted into the mechanism in order to reset the escape release.
