Problem Recommended Action

Problem:

Operators and maintenance personnel can enter the defined hazard area of the ACCUSTAK® through the stack exit area without locking out the machine as directed in the operator manual. Entering the hazard area while the machine is energized exposes personnel to a risk of injury.


When the Hazardous Energy Lockout procedure in your operator/maintenance manual is followed, the ACCUSTAK is de-energized for safe entry.

 

If these bolts have loosened up, we recommend that you retighten them at the torque value recommended below.

Recommended action:

Alliance offers an optional stack exit light curtain retrofit for the ACCUSTAK. The optional safety light curtain is recommended for installations that require additional safeguards beyond required lockout/tagout procedures.
This safety light curtain allows stacks to exit but causes the safety circuit to de-energize the ACCUSTAK if operators and/or other personnel enter the hazard area through the stack exit. The light curtain will not affect entry into the hazard area from other areas of the machine.

 

If you would like more information or have any questions, please call Mr. Gary Kneale of Alliance Field Service at: (509) 842-5134.
