Chemical Storage and Incompatibilities John Herrington
Lecture for 20 minutes or so • Video
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:
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)
Long-Term Storage Considerations • Peroxide Formers • Date the Containers • Test for Peroxides • Especially before distillation or concentrating
Long-Term Storage Considerations Peroxide Formers
Long-Term Storage Considerations Deliquescent/Hygroscopic Chemicals
Long-Term Storage Considerations • Chemicals That Dry Out • -Picric Acid • -Benzoyl Peroxide • Sublimation • -Iodine • -p-Dichlorobenzene • Decomposition • -Hydrogen Peroxide • -Calcium Hypochlorite
