Energy sources on a typical meat band saw
Every machine is different: check your model's nameplate, wiring and the manufacturer's manual. This is where most meat band saws get their energy and how it is usually isolated.
| Energy | Typical magnitude | Isolating device | How to control it |
|---|---|---|---|
| Electrical | 208–480 V 3-phase | Machine or wall disconnect | Switch OFF and lock and tag the disconnect. |
| Stored mechanical (motion, springs, tension) | Blade and wheels coasting; blade under tension | Wheel brake (if fitted); tension handle | Wait for the blade and wheels to stop. Release blade tension only as the manufacturer's manual describes, and only when the task requires it (for example, changing the blade). |
Shutting it down
- Stop the saw with the normal STOP control.
- Apply the wheel brake if the saw has one.
Releasing stored energy
- Confirm the blade and both wheels are stationary before opening the wheel doors.
- If the blade must be removed, release tension following the manufacturer's procedure.
Verifying isolation
- Press START: the saw must not start. Return the control to OFF.
Things people miss
- Wheel door interlocks do not replace lockout.
Turn this into your written procedure
Add your company, the machine ID, the voltage and where each disconnect and valve is. You get a machine-specific procedure that follows the structure of 29 CFR 1910.147(c)(4), with an approval block and printable DANGER tags.

Does a meat band saw need its own lockout procedure?
OSHA 29 CFR 1910.147(c)(4) requires documented procedures for the control of hazardous energy. A procedure is not required only when all eight conditions of the exception in (c)(4)(i) are met, for example a single energy source that can be readily identified and isolated. Most machines with more than one energy source need a written, machine-specific procedure.
Is unplugging enough?
For cord-and-plug equipment, the lockout standard does not apply when the equipment is unplugged and the plug is under the exclusive control of the employee doing the work (1910.147(a)(2)(iii)(A)). If the plug can be out of sight or reach, use a plug lockout cover with a personal lock.
Is the interlocked guard enough?
No. Guard interlocks and emergency stops are not energy isolating devices and do not replace lockout during servicing, cleaning or clearing jams.
General information, not legal advice. Verify every energy source on the actual machine and have the procedure approved by a qualified person.
