Red Dragon: Gate Jamming in Red Dragon PSD

Apr 22 2010
Details:
An incident occurred when an operator removed and replaced the hopper in operation while failing to clear the top two spheres from the gate assembly. This action caused the gate to be jammed in the closed position.
 
This issue is currently addressed with a note on page 28 of the operating manual. The note states:
 
 CAUTION
If the hopper is removed during operations, the top two spheres in the gate assembly must be retrieved before re-attaching the hopper.
Failure to do so may prevent opening of the gates.
