Materials Handling, Storage, Use, & Disposal

1. CHASSE Building Team and Trade Partners will ensure that all materials stored in tiers will be stacked, racked, blocked, interlocked, or otherwise secured to prevent sliding, falling or collapse.

2. When a difference in road or working levels exist, means such as ramps, blocking, or grading will be used to ensure the safe movement of vehicles between the two levels.

3. All employees required to work on stored material in silos, hoppers, tanks, and similar storage areas will be equipped with personal fall arrest equipment meeting the requirements of Subpart M of this part.

4. Bagged materials will be stacked by stepping back the layers and cross-keying the bags at least every 10 bags high.

   1. Materials will not be stored on scaffolds or runways in excess of supplies needed for immediate operations.

   2. Brick stacks will not be more than 7 feet in height.

   3. When a loose brick stack reaches a height of 4 feet, it will be tapered back 2 inches in every foot of height above the 4-foot level and when masonry blocks are stacked higher than 6 feet, the stack will be tapered back one-half block per tier above the 6-foot level.

5. Lumber will be stacked on level and solidly supported sills. Lumber will be so stacked as to be stable and self-supporting.

   1. Lumber piles will not exceed 20 feet in height provided that lumber to be handled manually will not be stacked more than 16 feet high.

6. Structural steel, poles, pipe, bar stock, and other cylindrical materials, unless racked, will be stacked and blocked so as to prevent spreading or tilting.

Material stored inside buildings under construction will not be placed within 6 feet of any hoist way or inside floor openings, nor within 10 feet of an exterior wall which does not extend above the top of the material stored.

1. “Housekeeping.” Storage areas will be kept free from accumulation of materials that constitute hazards from tripping, fire, explosion, or pest harborage. Vegetation control will be exercised when necessary.

2. Aisles and passageways will be kept clear to provide for the free and safe movement of material handling equipment or employees and be kept in good repair.

3. Used lumber will have all nails withdrawn before stacking.

CHASSE Building Team and Trade Partners must ensure that rigging equipment:

1. Has permanently affixed and legible identification markings as prescribed by the manufacturer that indicate the recommended safe working load;

2. Not be loaded in excess of its recommended safe working load as prescribed on the identification markings by the manufacturer; and

3. Not be used without affixed, legible identification markings.

4. Subcontractor rigging equipment for material handling will be inspected prior to use on each shift and as necessary during its use to ensure that it is safe. Defective rigging equipment will be removed from service.

5. Special custom design grabs, hooks, clamps, or other lifting accessories, for such units as modular panels, prefabricated structures and similar materials, will be marked to indicate the safe working loads and shall be proof-tested prior to use to 125 percent of their rated load.

Rigging equipment, when not in use, will be removed from the immediate work area so as not to present a hazard to employees.

Non-compatible materials will be segregated in storage.

1. Whenever materials are dropped more than 20 feet to any point lying outside the exterior walls of the building; an enclosed chute of wood, or equivalent material, will be used.

2. When debris is dropped through holes in the floor without the use of chutes, the area onto which the material is dropped shall be completely enclosed with barricades;

   1. not less than 42 inches high and not less than 6 feet back from the projected edge of the opening above.

   2. Signs warning of the hazard of falling materials shall be posted at each level.

   3. Removal shall not be permitted in this lower area until debris handling ceases above.
