Classification of Debris (IS 13416 Part 3:1994)

According to Clause 3.1 and 3.1.2, debris from construction/demolition is classified into four categories after removing salvageable materials:

1. Earth and Soil Debris: Includes earth, stones, and low-value inert materials.
2. Plaster, Mortar, and Brick Debris: Waste from plaster, mortar, bricks, blocks, tiles, slates.
3. Hardcore Debris: Includes concrete, broken bricks, stones, roofing sheets, pipes, sanitaryware, steel, wood, glass, etc.
   • Storage & Disposal: Must be stored separately in designated/approved sites.
   • Reuse: Suitable for road work and filling low-lying areas.
4. Miscellaneous Debris: Wall paper, waste wood, and other non-structural materials.

Key Specifications:

• Separate storage for hardcore debris.
• Consult local authorities for disposal sites.
• Use IS 2925:1984 helmets for safety during debris handling.
• Follow fire safety norms as per IS 13416 (Part 5).

Tools for Removal of Debris (IS 13416 Part 3 - Clause 4 & 5)

Key Hand Tools:

• Spades, pickaxes, shovels
• Hammers, chisels (for breaking large pieces)
• Pneumatic hammers (for crushing hard debris)
• Mortar pans, baskets, wheelbarrows
• Crowbars

Mechanical Equipment:

• Hoists, lifts, cranes for vertical transport
• Bulldozers, dump trucks, hydraulic rams for dumping and clearing
• Grab buckets, excavators for loading
• Animal-driven carts or mechanical vehicles for transportation

Specifications & Safety Precautions (Clause 6)

• Debris chutes: Made of wood or GI sheet/steel-covered wood; avoid throwing debris from height.
• Dust control: Sprinkle water to prevent dust nuisance.
• Load limits: Avoid overloading intermediate floors with debris.
• Protective gear: Helmets (IS 2925:1984), gloves, boots, goggles mandatory.
• Barricading: Work areas must be barricaded with warning signs.
• Debris dumping: Separate glass and steel to prevent injury; dump in approved sites only.
• Transportation: Use covered wheelbarrows or trucks to avoid nuisance.
• Timing: Prefer daytime work; provide artificial lighting if visibility is poor.
