• Inventories
• Chemical Name
• Original Amount
• Manufacturer (for MSDS)
• Location (at least room number)

• Purchasing (Procurement)
• Purchase Only the Amount Needed
• Purchase Smaller or Custom Containers
• Check the Inventory Before Purchase

• Labeling
• Label ALL containers
• -Except for Immediate Use
• Unknowns are Dangerous and Expensive
• Inspect Chemicals and Labels At Least Every 6
  Months
• Replace Damaged or Worn Labels
• Dispose of Chemicals That Have Not Been Used for
  12 to 18 Months

• Storage
• Segregate According to Hazard Class
• Acids with Acids, Bases with Bases, etc.
• Follow Manufacturers Recommendations
• -Labels and
• -MSDS

Color-coded Labels for Compatible Storage The
SAF-T-DATA label suggests a method for setting
up your chemical storage area. The background
color indicates the type of storage required.
Simply store products with the same color
together, except where indicated below, and
follow these recommendations for appropriate
storage
Blue Store in a secure poison area.
Red Store in a flammable liquid storage area.
Yellow Store separately and away from flammable or combustible materials
White Store in a corrosion-proof area.
Green Store in a general chemical storage area.
Striped Assess storage individually. A striped label indicates that the material is incompatible with other materials in the same color class.

• Segregation Tips
• Mineral Acids Away From Organic Acids
• Organics Away From Oxidizers
• Refer To the Incompatibles Chart
• Do NOT Use Alphabetical Order!
• Water-Reactive Materials MUST Be Stored Away
  From All Other Materials
• Acute Poisons Should Be Locked

• Long-Term Storage Considerations
• Peroxide Formers
• Ethers (Isopropyl and Diethyl Ether)
• Acetals
• Olefins with Allylic Hydrogen
• Dienes
• Ureas, Amides, Lactams (Sodium Amide)
• Alkali Metals and Alkoxides (Potassium)
• Vinyl Monomers, Vinyl Halides, Acrylates,
  Methacrylates (Divinyl Acetylene and Vinylidene
  Chloride)
