- Chute openings should be 48 inches or less in height measured along the wall of the chute. Openings at all floors below the top floor must be closed when the chute is not in use.
Chute openings should be 48 inches or less in height measured along the wall of the chute.
- Provide 42-inch high guardrails/barricades at least 6 feet back from the projected edge of the opening above where debris is dumped manually through floors without chutes.
- Where debris is dumped using mechanical equipment or wheel barrows, provide 4-inch wide by 6-inch high toeboards/bumpers.
- Block off storage spaces to which material is dumped unless the openings are used for the removal of materials and kept closed when material is not being removed.
- Barricade and mark all debris-dropping areas. Post warning signs on each side of the debris opening at each floor level.
- Ensure debris is not removed in lower areas until all debris-handling ceases in areas above.
- Install a substantial gate in each chute at or near the discharge end. Make sure the discharge gate closed off when not in use.
