What is in the procedure
8 sections. Regulatory language is fixed and passes through verbatim. Sections marked customized get rewritten around your facility, your equipment, and your job titles.
- 01
Purpose
FixedThis procedure governs safe operation of vertical cardboard balers and trash compactors.
- 02
Scope
CustomizedThis procedure applies to every vertical baler, horizontal baler, and stationary or self-contained compactor at this facility, and to every person who loads, cycles, ejects a bale from, or services that equipment.
- 03
Authorized Operators
CustomizedOnly employees who are 18 years of age or older, who have completed documented hands-on training on the specific machine, and who appear on the current authorized operator list may operate a baler or compactor or clear...
- 04
Procedure: Loading and Cycling
Fixed1. Pre-use check: confirm all guards and covers are in place, the gate or door interlock stops the ram when the door is opened, the emergency stop is accessible and unobstructed, there are no hydraulic leaks or damaged...
- 05
Procedure: Bale Ejection and Tie-Off
Fixed1. Bale only when the chamber is full to the marked full-bale line, so the finished bale is dense enough to hold its shape and not top-heavy.
- 06
Procedure: Jam Clearing Requires Lockout
FixedClearing a jam, freeing stuck material, adjusting the platen, or reaching into the chamber for any reason is servicing work and requires full lockout/tagout.
- 07
Guarding, Interlocks, and Maintenance
CustomizedGuards, chamber door interlocks, gate switches, and belt and chain drive covers are safety devices, not obstacles.

Every SOP generated from this template cites the paragraphs below, with a plain-language summary of what each one requires. Citations are informational and are not legal advice.
| Standard | Title | What it requires |
|---|---|---|
| 29 CFR 1910.212(a)(1) | Machines: types of guarding | One or more methods of machine guarding must protect operators and other employees in the machine area from hazards such as the point of operation, ingoing nip points, rotating parts, and flying chips or sparks. |
| 29 CFR 1910.212(a)(2) | Machines: general requirements for machine guards | Guards must be affixed to the machine where possible and secured elsewhere if for any reason attachment to the machine is not possible, and the guard must not offer an accident hazard in itself. |
| 29 CFR 1910.212(a)(3) | Machines: point of operation guarding | The point of operation of a machine whose operation exposes an employee to injury must be guarded. The guarding device must conform to any appropriate standards for it or, in the absence of applicable specific standards, must be designed and constructed to prevent the operator from having any part of their body in the danger zone during the operating cycle. |
| 29 CFR 1910.212(b) | Machines: anchoring fixed machinery | Machines designed for a fixed location must be securely anchored to prevent walking or moving. |
| 29 CFR 1910.147(c)(4) | Control of hazardous energy: energy control procedures | Documented, machine-specific energy control procedures must be developed and used for the control of potentially hazardous energy, including the specific steps for shutting down, isolating, blocking, and securing the machine and for relieving stored energy. |
| 29 CFR 1910.147(d) | Control of hazardous energy: application of control | Lockout or tagout must be applied in sequence: prepare for shutdown, shut the machine down, isolate every energy source, apply lockout or tagout devices, relieve stored energy including hydraulic pressure and gravity-supported components, and verify isolation before servicing begins. |
| 29 CFR 1910.219(e) | Mechanical power-transmission apparatus: belt, rope, and chain drives | Belt, rope, and chain drives must be guarded where the drive runs seven feet or less from the floor or working platform, so that employees cannot reach the moving drive during operation. The duty applies only where such a drive is present on the machine. |
Compliance checklist
What an inspector looks for
Guards protect the point of operation, nip points, and moving parts, and no guard is missing or defeated
29 CFR 1910.212(a)(1)
The chamber door interlock prevents the ram from cycling when the door is open, and interlock function is tested on the PM schedule
29 CFR 1910.212(a)(3)
The machine is securely anchored and does not move or walk during operation
29 CFR 1910.212(b)
A documented machine-specific energy control procedure exists for each baler and compactor
29 CFR 1910.147(c)(4)
Jams and all chamber entry are cleared only after lockout, stored hydraulic energy relief, platen blocking, and zero-energy verification
29 CFR 1910.147(d)
Any belt, rope, or chain drive on the machine is guarded against contact
29 CFR 1910.219(e)
No employee under 18 operates, loads, services, or clears a baler or compactor
A current authorized operator list is posted at the machine and training is documented
Prohibited materials are placarded at the machine and are not loaded into the chamber
