Warehouses
Warehouse buildings store goods and materials, with assessment priorities varying based on stored commodities. Key concerns include floor slab capacity for racking and forklift loads, fire protection appropriate to stored materials, ventilation for worker health and product preservation, loading dock safety, and compliance with factory and trade licensing requirements.
Overview
Warehouse buildings store goods and materials, with assessment priorities varying based on stored commodities. Key concerns include floor slab capacity for racking and forklift loads, fire protection appropriate to stored materials, ventilation for worker health and product preservation, loading dock safety, and compliance with factory and trade licensing requirements.
Assessment Context
Warehouses in Bangladesh serve manufacturing, retail distribution, cold storage, garment exports and general trading operations. Building configurations range from simple single-storey steel-frame structures to multi-storey reinforced concrete facilities. The assessment priorities depend heavily on what is stored — flammable goods, food products, garments, chemicals and general merchandise each present different risk profiles and regulatory requirements.
Structural Considerations
Warehouse floors must support heavy racking systems, stored goods and forklift operations. Ground-floor slab design is critical — point loads from racking uprights, wheel loads from forklifts and uniform loads from bulk storage all need verification. Multi-storey warehouses require assessment of floor slab capacity at each level. Steel-frame warehouses need assessment of column bases, connections, bracing and roof truss condition. Portal frame structures are common and vulnerable to lateral displacement if bracing is compromised.
Fire Safety
Fire risk in warehouses depends on stored commodities. High-rack storage of combustible goods (garments, plastics, paper) requires sprinkler systems designed for the specific commodity and storage height. Assessment should verify: fire separation between warehouse and office or residential areas, sprinkler system design adequacy for actual storage configuration, fire detection coverage, means of egress for warehouse workers, fire hydrant access and water supply, and fire brigade access to the building. Warehouses storing flammable liquids or chemicals may require additional fire protection measures and environmental containment.
Ventilation and Environment
Worker health in warehouses depends on adequate ventilation, particularly for facilities storing chemicals, paints or other hazardous materials. Temperature-controlled warehouses (cold stores, pharmaceutical storage) require assessment of refrigeration systems, insulation integrity and temperature monitoring. General warehouses need natural or mechanical ventilation assessment for worker comfort and prevention of condensation damage to stored goods.
Loading and Access
Loading docks are high-risk areas for accidents. Assessment should cover dock leveller condition, dock shelter integrity, vehicle restraint systems, adequate lighting, slip-resistant surfaces, and separation between pedestrian and vehicle routes. Internal traffic management — forklift routes, pedestrian walkways, racking aisle widths — is a safety-critical assessment item.
Operational Characteristics
• Heavy vehicle movements: forklifts, pallet jacks, dock levellers, HGV loading bays
• Racking systems carrying significant concentrated loads
• Variable occupancy with zones for storage, picking, packing and dispatch
• Cold storage areas in temperature-controlled warehouses
• Shift operations with potential 24/7 activity
Primary Hazards
• Forklift collisions with personnel, racking or building structure
• Fire spread through large open volumes with high-piled combustible storage
• Falls from height during racking access or mezzanine operations
• Manual handling injuries from repetitive lifting
• Structural damage to portal frame columns from vehicle impact
Essential Documents
• Structural design certificate (particularly for racking and mezzanine loads)
• Fire safety certificate and risk assessment
• Racking inspection reports (at least annual by a competent person)
• Forklift and materials handling equipment inspection certificates
• Insurance survey reports
• Hazardous materials storage documentation (if applicable)
Important Systems
• Fire suppression: sprinkler systems designed for high-piled storage configurations
• Smoke and heat exhaust ventilation (SHEV) systems
• Loading dock equipment: dock levellers, dock shelters, vehicle restraints
• Industrial lighting suited to high-bay environments
• Ventilation and heating systems (including cold store refrigeration)
• Security: perimeter fencing, CCTV, access control at gates
Typical Concerns
• Fire strategy adequacy for the type and height of stored goods
• Separation between pedestrian routes and vehicle movement areas
• Structural integrity of portal frame columns (impact damage history)
• Adequacy of natural or mechanical ventilation
• Cold store insulation integrity and refrigerant leak monitoring
Common Red Flags
• No racking load notices displayed or loads exceeding posted limits
• Sprinkler heads obstructed by stored goods stacked too close to ceiling
• No pedestrian walkways marked on the warehouse floor
• Emergency exits blocked by pallets or equipment
• Portal frame column base plates showing signs of vehicle impact
Suggested Professional Assessments
• Fire risk assessment specific to high-piled storage
• Structural condition survey of portal frames and floor slab
• Traffic management and pedestrian safety review
• Insurance risk survey
• Cold store integrity and refrigeration plant assessment (if applicable)
Sustainability Considerations
• LED high-bay lighting with occupancy and daylight sensors
• Natural ventilation strategies to reduce mechanical ventilation energy
• Insulation upgrades to reduce heating costs in temperate climates
• Electric forklift fleet transition from diesel or LPG
• Rainwater harvesting from large roof catchment areas
