Chemical Compatibility

• Brown University

• Benefits of Proper Chemical Storage
• Provides for effective management of chemicals
• Minimizes potential exposures
• Prevents chemicals from accidentally mixing
• Reduces the risk of fire

Presented by the Rhode Island Chemical Safe
Schools Committee
39

• Common Storage Mistakes
• Alphabetical Storage
• Organize chemicals first by COMPATIBILITY not
  alphabetically. Some examples of potential
  problems with alphabetical storage include, but
  is not limited to
• Aluminum metal accidentally mixed with ammonium
  nitrate may cause an explosion.
• Sodium nitrate accidentally mixed with sodium
  thiosulfate may cause an explosion.

Presented by the Rhode Island Chemical Safe
Schools Committee
40

• Common Storage Mistakes
• Storage by Hazard Class
• Storage of chemicals only by hazard class such as
  Flammable, Corrosive, or Poison is too broad and
  will result in a number of incompatibility
  issues.
• One example, is that nitric acid mixed with oleic
  acid or tannic acid may react and cause a fire.

• Common Storage Mistakes

Health Hazard Toxic if inhaled, ingested, or
absorbed through the skin. Store in a secure
area.
Flammable Store in area segregated for
flammable reagents.
Presents no more than a moderate hazard in any of
the categories above. For general chemical
storage.
Corrosive May harm skin, eyes, mucous
membranes. Store away from red-, yellow-, and
blue coded reagents.
Reactive and oxidizing reagents May react
violently with air, water, or other substances.

• The Assignment
• Combine two actual chemical inventories from
  Rhode Island high schools into compatible groups
  and identify a method to help high school
  employees sort chemicals for safe storage.

Presented by the Rhode Island Chemical Safe
Schools Committee

• Safety First!
• For your own personal safety it is recommended
  that you use appropriate eye protection, chemical
  protective gloves, and other PPE necessary to
  complete this task.

Presented by the Rhode Island Chemical Safe
Schools Committee
48

• Recommended Steps to Compatibility
• Step 1 Reduce Inventory
• The more chemicals that you can dispose of prior
  to segregating into groups the easier this
  process will be. You should start reducing
  inventory by
• Disposing of chemicals that you dont want.
• Disposing of chemicals that you dont need.
• Disposing of ALL chemicals on the RI High School
  list of banned chemicals.

• Recommended Steps to Compatibility
• Step 2 Nitric acid and sulfuric acid should be
  separated from most chemicals and each other.
• Whenever possible, isolate chemicals that require
  special storage or have a high degree of hazard.

• Recommended Steps to Compatibility
• Step 3 Separate Solids from Liquids
• By completing this step you will have eliminated
  many potential compatibility issues while gaining
  efficiency in your available storage.
• Most solids can be stored on shelves.
• Most liquids need to be stored in trays or in
  cabinets.

Presented by the Rhode Island Chemical Safe
Schools Committee
51

• Recommended Steps to Compatibility
• Step 4 Separate Organic from Inorganic
• This is one of the most important steps in the
  process of chemical compatibility and storage and
  will help avoid some classic incompatibility
  issues.
• An organic compound is any member of a large
  class of chemical compounds whose molecules
  contain carbon and hydrogen bonded to each other
  therefore, carbides, carbonates, carbon oxides
  and elementary carbon are not organic.
• An inorganic compound is any chemical compound
  that is not an organic compound.

• Group the following as organic or inorganic

• Recommended Steps to Compatibility
• Step 5 Further Segregate into Compatibility
  Groups
• Most compatibility charts and systems agree that
  organic chemicals and inorganic chemicals should
  be further segregated into compatibility groups.
• A suggested arrangement of compatible groups can
  be found in the NIOSH School Chemistry Safety
  Guide and in the Flinn Scientific Chemical
  Catalog/Reference Manual.

Presented by the Rhode Island Chemical Safe
Schools Committee
56

• Final Step to Compatibility
• Step 6 (Optional) If your facility lacks
  storage space it may be necessary to combine
  solids and liquids from the same compatibility
  group (e.g., solid organic group O1 may be stored
  with liquid organic group O1 chemicals).

Presented by the Rhode Island Chemical Safe
Schools Committee
57

• Conclusion
• In general, the Flinn Scientific suggested
  pattern of chemical storage should work well for
  high school stockrooms provided that chemicals
  banned from RI high schools are kept out of the
  inventory. There is no perfect storage pattern
  and even the Flinn Scientific pattern will result
  in some incompatibility issues such as sodium
  azide stored near lead nitrate.

Sodium Azide is on the RI High School list of
banned chemicals and should not be used
