OSHA standard: 29 CFR 1926.250 · 1926.252

At a glance

• Stacks fail sideways: stable base, limited height, tied or stepped back
• Arizona wind turns sheet goods into missiles — secure them the day they arrive
• Nothing stored within 6 feet of an edge, an opening, or a hoist zone
• Disposal is a workflow, not a pile — sort it, contain it, haul it

Introduction

Materials hurt people twice: once when a stack falls on someone, and again slowly, as stored-anywhere piles turn the site into a maze of trip hazards, fire load, and blocked exits. Storage looks like logistics, but it's a safety system — stack height, base condition, edge setbacks, and wind securing all decide whether material stays put. Today's talk covers stacking that doesn't fall, storing that doesn't burn or block, and getting waste off site before it becomes a hazard of its own.

Stacking That Stays Stacked

• Firm, level base — a stack on soft or sloped ground is already falling, slowly
• Height limits exist: block and brick stacks taper back above 4 feet; lumber stacked by hand stays under 16 feet, under 20 by machine; bagged material steps back each layer
• Pipe, rebar, and round stock get racked or chocked — a rolling pile releases without warning
• Pull from the TOP of stacks, never from the middle or the side — undermining a stack is how it lands on you
• Leave working aisles between stacks wide enough for people AND the equipment that serves them

Wind, Edges & Zones

• Sheet goods — plywood, drywall, foam, metal panels — get flat-stacked or strapped THE DAY they land; a monsoon outflow gust arrives faster than a crew can react
• Nothing loose stored on roofs or upper decks without securing — what blows off a deck lands on someone
• Keep storage 6 feet back from slab edges, openings, and excavations; further for tall stacks
• Never block exits, extinguishers, electrical panels, hydrants, or eyewash stations — walk the zone after every delivery

Disposal Is Part of the Job

• Separate the streams: general debris, recyclable metal, concrete/masonry, and hazardous waste (solvents, adhesives, aerosols, oils) — hazardous never goes in the general bin
• Overfilled dumpsters shed on the wind and on the hauler — call the pull before the crown
• Nail-studded lumber goes to the pile with nails pulled or bent — the disposal pile is not exempt from the nail rule
• Chutes for elevated debris, never free-drops; barricade below any loading operation

Key takeaways

• Level base, height limits, taper the stacks
• Round stock racked and chocked, always
• Pull from the top — never undermine a stack
• Sheet goods secured the day they arrive (wind!)
• 6 feet back from edges and openings
• Hazardous waste gets its own container, every time

Questions for your crew

1. Stacks fail sideways: stable level base, height limits, tied or stepped back.
2. Round stock — pipe, rebar bundles, poles — racked and chocked, always.
3. Pull from the top of a stack, never undermine it.
4. Arizona wind turns sheet goods into missiles — secure them the day they arrive.
5. Nothing stored within 6 feet of an edge, an opening, or a hoist zone.
6. Disposal is a workflow, not a pile: sorted, contained, hauled — and hazardous waste gets its own container, every time.
