Well-designed hazardous materials and waste storage areas minimize and contain spills and provide for easy inspection of containers:

• Use high quality, resealable containers to prevent spills, evaporative losses, and contamination; and keep the lids/seals closed when not in use
• Arrange raw materials storage with access to front and back of shelving so new materials can be placed behind older stock
• Keep raw material and waste storage area aisles clear of obstructions:
• Allow elbow room to access all containers easily and minimize spills
• Space containers to allow inspection for corrosion and leaks
• Maintain clear, even surfaces on pathways used by workers or equipment
• Keep storage areas clean and well-lit
• Stack containers no higher than recommended by manufacturer, in a way which minimizes the potential for tipping, tearing, puncture, or breakage
• Don't stack equipment against containers
• Make sure containers and shelving or storage areas are earthquake safe
• Insulate electrical circuitry and check frequently for corrosion and potential sparking
• Raise drums off floor to prevent corrosion from concrete "sweating"
• Provide secondary containment and maintain proper distance between different materials
• Install sloped concrete floors and curbs or berms for spill containment in areas such as vehicle maintenance
• Cover outdoor storage areas to prevent contamination of storm water
• Secure storage areas to minimize liability and hazards of intrusion or dumping
