  • A Chemists last words
  • And now the tasting test
  • And now shake it a bit
  • In which glass was my mineral water?
  • Why does that stuff burn with a green flame?!?
  • And now the detonating gas problem
  • This is a completely safe experimental setup
  • Now you can take the protection window away
  • And now a cigarette

  • Where did this come from?
  • I need the calcium carbide to do my special
    demo
  • You ordered 4 liters of HCL? I ordered 4
    liters of HCl too!!!!
  • It was so nice of Rickys dad to give me 1 kg of
    silver nitrate.
  • Hey you know that 1/2 liter of Nitric acid we
    were looking for? Well I found it!

Chemical Compatibility

  • Brown University

38
  • 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.

Presented by the Rhode Island Chemical Safe
Schools Committee

  • Common Storage Mistakes
  • Example of Chemical Distributor Label
  • Fisher Scientific Labels ChemAlert Storage
    Codes

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
47
  • 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.

Schools Committee

  • 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.

Presented by the Rhode Island Chemical Safe
Schools Committee

  • Exercise
  • 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
