Stack material so it stays put
Housekeeping 5 min 29 CFR 1926.25
Why it matters
A stack that slides, a column of bags that leans, or a pipe that rolls becomes a hazard in the walk. 1926.25 is about keeping areas clear and keeping materials from becoming a hazard. Stack it so it cannot move, and do not build a pile you have to climb.
The talk
Stack lumber flat. Band it, or block it, so it cannot slide. Loose boards on a slope will walk off the pile when someone bumps them. Set the stack on level ground. Do not set it on a mound of dirt or on a round pipe. Keep the ends from hanging so far that the pile sags and slips. 1926.25 is about keeping areas clear and keeping materials from becoming a hazard. A stack that slides into a walk is a trip, and it is also a load that can hit someone. If the band is cut, put blocks on it before you walk away.
Bagged goods are cross-stacked, not piled in one tall column. A single column of bags leans, then goes over. Cross each layer so it locks the layer under it. Do not stack so high that a person has to climb the pile. If you cannot reach the top from the ground without climbing the material, stop adding layers. Climbing a pile is how bags shift under your boots and come down with you. Start another stack, or have the material set where you can reach it without using the pile as a ladder.
Keep stacks back from a leading edge. A leading edge is the open side of a floor or a roof where the wall is not there yet. A stack at that edge can be kicked off, or a person can trip on it and go over. Keep stacks out of a doorway. People come through a door with their hands full and do not see a low pile until their boot hits it. Round stock is chocked. Pipe, rolls, and poles will roll if they sit on the round. Put chocks on both sides so one bump from a truck or one pulled piece does not start the whole pile rolling.

Talk about it
- Which stacks on this job can slide, lean, or roll?
- Where are we too close to a leading edge or a doorway?
- What round stock still needs chocks on both sides?
