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 establishes how orders are released in waves and picked across multiple zones, with each zone picking only its own lines and passing the order container on to the next zone.
- 02
Scope
CustomizedThis procedure applies to wave released zone picking, where an order is split into zone assignments and a tote, carton, or cart travels through the zones in sequence until every line is picked.
- 03
Responsibilities
CustomizedWave planners size and release waves against available staffing and carrier cutoffs, and do not release a wave into a zone that is already backed up.
- 04
Procedure: Wave Release and Zone Start
CustomizedA wave is a commitment of work to a fixed number of people in a fixed amount of space, so it is sized before it is released and never after.
- 05
Procedure: Zone Picking and Tote Handoff
FixedIn zone picking, the tote carries the order between people who never speak to each other, so the tote itself has to carry the truth.
- 06
Procedure: Congestion and Pedestrian Safety at Zone Boundaries
CustomizedCongestion in a wave is predictable, so it is managed as part of the procedure rather than treated as an event.
- 07
Exception Handling and Wave Close-Out
CustomizedStop and report rather than improvising whenever any of the following occurs: a tote arrives in a zone the system does not expect it in, a tote arrives with contents that do not match its label or license plate, a tote...

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 1910.176(a) | Handling materials, general: use of mechanical equipment | Where mechanical handling equipment is used, sufficient safe clearances must be allowed for aisles, at loading docks, through doorways, and wherever turns or passage must be made. Aisles and passageways must be kept clear and in good repair, with no obstruction across or in aisles that could create a hazard, and permanent aisles must be appropriately marked. |
| 29 CFR 1910.22(c) | Walking-working surfaces: access and egress | The employer must provide, and ensure that each employee uses, a safe means of access and egress to and from walking-working surfaces. |
| 29 CFR 1910.22(a) | Walking-working surfaces: general requirements | Walking-working surfaces must be kept in a clean, orderly, and sanitary condition, free of hazards such as sharp or protruding objects, loose boards, spills, and debris that create slip, trip, or fall hazards. |
Compliance checklist
What an inspector looks for
Overflow containers, carts, and pallets are never staged in an aisle, cross aisle, doorway, or crossover, which stay clear and in good repair
29 CFR 1910.176(a)
Nothing is staged in front of an exit, an electrical panel, or a fire extinguisher
Every zone has an open, walkable route in and out, and associates use designated crossovers rather than stepping over, under, or through a conveyor
29 CFR 1910.22(c)
Zone and boundary floors are kept clean and free of wrap, banding, dunnage, and spills
29 CFR 1910.22(a)
A tote is released to the next zone only when every assigned line is picked or formally shorted in the system
Pickers never reach into a moving conveyor line or clear a jam, and waves are held rather than released onto a congested zone
