Maintenance and Repair Considerations Training Short

Why is "Zero Energy State" critical during machine repair?

Even if a machine is turned off, stored energy (pneumatic, hydraulic, or gravitational) can cause unexpected movement; Lockout/Tagout ensures all energy is dissipated before work begins.

Can I use my hands to clear a jam if the machine is paused?

No. You should always use long-handled tools or specialized equipment to clear debris to keep your hands out of the "point of operation".

Is it ever safe to lubricate a machine while it is running?

Only if the lubrication points are located outside the guards or if specialized extension tools allow for safe access without exposing the worker to moving parts.

What is the operator’s role during a major repair?

An operator must be able to recognize mechanical failures, safely shut down the unit, and correctly apply their individual tag or lock as part of the facility’s LOTO program.

How do maintenance records improve daily safety?

Documenting repairs ensures that the next shift is aware of any mechanical quirks or recent part replacements, preventing accidents caused by unexpected machine behavior.
