Trash compactor quarterly maintenance checklist

Staff and chute users told the compactor is down

Building or loading staff told the round's window, and chute intake doors signed or closed where a chute feeds the unit, so no one loads waste while the tech is at the chamber.

Lock and tag hung on every source feeding the compactor

Power unit and control feeds locked and tagged, key pulled, start tried dead. Ram checks: block out, people clear, covers on, locks off by whoever hung them, cycle run, re-locked.

Ram retracted and blocked before hands enter the chamber

Ram at rest fully retracted and blocked or pinned as the manufacturer's instructions direct, so stored hydraulic pressure cannot move it while anyone reaches past the loading opening.

Chamber floor and ram guides cleared of packed waste

Waste packed on the chamber floor, along the ram guides and at any cleanout removed with a tool, not by hand, so the ram can travel its full stroke on the next cycle.

Oil level, condition and leaks checked

Reservoir at level, oil not milky or burnt, no weeping at the cylinder, hoses or fittings, no puddle under the unit.

Hydraulic hoses checked for chafe, bulging and routing

Hoses from the power unit to the cylinder free of worn or cracked covers, blisters and kinks, clamped clear of sharp edges and the ram path.

Ram operation and cycle time observed

Ram driving to full stroke and retracting smoothly, cycle time in normal range, no shudder or stall under load.

Interlock switch mounting and bypass evidence checked

Switch and actuator at each loading door fastened and aligned, no tape, wedge, jumper or spare actuator left near it; a bypass found is reported and the unit locked out until repaired.

Interlocks, keyed control and guarding verified as observed

Access door and interlock stopping the ram, key control functioning, guards in place, checked by observation only, never by reaching in.

Chute or hopper sprinkler head clear where one is fitted

Where a sprinkler head protects the chute or hopper, it's seen undamaged, unpainted and not loaded or blocked by debris. Problems go to the owner's fire protection contractor.

Container/chute latch and seal checked

Container latched square to the charge box, gasket sealing, no gap letting liquid or debris escape at the joint.

Container-full signal and hauler pickups checked

Full light or gauge responding where fitted, and pickups keeping pace with how fast the container fills, so an overfull box doesn't force waste back through the charge box.

Pad kept clean, odor and pests controlled

Charge box and pad clear of spilled waste, no standing leachate, drain to the sanitary point clear where fitted.

Covers on, locks off and compactor handed back to staff

Blocks and tools out of the chamber, power unit cover fastened, any lock still hung removed by the person who hung it, a normal cycle run, key returned and staff told it's back.
