2. Safety
2.1. Safety Information
Do not work on the LBB Series oven without reading and understanding this section which
contains important information and warnings. Ignoring these warnings can result in death, serious
injury or damage to the machine and product.
2.1.1. Lockout
Carefully follow the established Lock Out Tag Out policies of
your company in all cases.
Machine lockout places the LBB Series oven into a zero energy state and prevents accidental
machine start up. Always follow the Lockout Procedure described in this Section before cleaning,
maintaining or repairing the LBB Series oven. An accidental start-up, while working on the LBB
Series oven, can result in serious injury or death.
2.1.1.1. Lockout Requirements
1. Every power source that can energize any element of the LBB Series oven must be shut off at
the closest possible power source. This includes air, water and electricity, including the
Disconnect Switch.
2. After energy sources are locked out, test to ensure circuits are de-energized.
2.1.1.2. Lockout Procedure
Personnel authorized to lockout equipment must have the necessary locks to perform the lockout.
1. Physically disconnect all electrical power to the machine or lockout the appropriate breaker
or disconnects.
2. Close all valves and bleed off any pressure.
3. Test for power by attempting a start with the machine controls.
4. Identify the Lockout Condition with a tag on the electrical disconnect and pneumatic shut off
valve.
5. When work is complete, remove all tags and restore the machine to its working state.
Danger!
Electrical panels contain high voltage. Disconnect and lock out
the power supply before working inside any electrical panels.
Failure to lock out the power supply can result in death or injury.
