inventory.

7. Chemical Storage
This section will first discuss general considerations
and requirements for chemical storage.
Next, it will provide specific information for the
storage of chemicals by hazard class.
7
8. Chemical Storage- Requirements
There must be an inventory list of hazardous
chemicals as defined in section 6.2 of the University
Chemical Hygiene Plan.
Chemical containers must be labeled with a minimum
of chemical name, hazard warnings and target organs.
Containers shall be dated when received and opened.
Accompanying material safety data sheets must be kept.
8
9. Chemical Storage
General Considerations:
Plan ahead for spills, accidents or emergencies.
Be aware of special storage conditions such as
temperature, relative humidity or limited shelf life.
Segregate chemicals by hazard class or compatibility.
9
10. Chemical Storage
General Considerations:
If available, use ventilated cabinets for volatile
toxics and odoriferous chemicals.
Use approved flammable storage cabinets for
flammable liquids.
Use secondary containers or trays for corrosives
and toxic solvents.
10
11. Chemical Storage
General Considerations:
When refrigerating flammables, only use refrigerators
specifically designed for flammable materials.
Do not store food in chemical storage refrigerators.
Label chemical storage refrigerators with the following:
No Food – Chemical Storage Only
11
12. Chemical Storage
General Considerations:
Avoid storing liquid chemicals above eye level.
Avoid storing chemicals in aisle ways.
Avoid over stocking shelves.
Avoid storing heavy containers above shoulder level.
Avoid storing chemicals in fume hoods or on counter tops.
Avoid storing chemicals near sources of heat or in direct
sunshine.
12
13. Chemical Storage – Hazard Class
At a minimum, chemicals should be segregated as:
Corrosives
Oxidizers
Flammable Liquids
Poisons or Toxic Chemicals
Reactive (water or time sensitive)
13
14. Chemical Storage – Corrosives
Corr
Store concentrated acids and bases separately.
H+ OH-
Keep corrosives away from organic chemicals and
combustible materials.
Use secondary catch basins for concentrated acids
and bases.
14
15. Chemical Storage –
The Ohio Fire Code regulates storage based on
occupancy, classification, building construction,
availability of flammable storage cabinets, quantities
and location of the laboratory. Appendix J of the
chemical hygiene plan provides a summary of the
fire codes. Contact the Department of Public Safety
(7-6300) for assistance with the interpretation of the
fire codes.
15
16. Chemical Storage – Flammable Liquids
As a general rule of thumb, no more than 10 gallons of
flammable liquids should be stored outside of an
approved flammable storage cabinet. Hospital patient
areas are typically much less (1 to 2 gallons).
See tables 2 and 3 of the chemical hygiene plan for
additional information on flammable liquids.
16
17. Chemical Storage – xidizers
Store oxidizers away from flammable and combustible
materials.
Store oxidizers away from reducing agents.
Maintain the minimum quantity needed and dispose of
unneeded material immediately.
See table 12 of the chemical hygiene plan for a partial list of
oxidizers.
17
18. Chemical Storage – To ic Chemicals
Store highly toxic materials in a dedicated storage fume hood.
Maintain the minimum quantity needed and dispose of
unneeded material immediately.
Store in unbreakable containers or use secondary containers.
Label storage areas with designated area signs.
See tables 9, 10, 11 and 13 of the chemical hygiene plan for
partial lists of toxic chemicals, carcinogens and reproductive
toxins.
18
19. Chemical Storage – Reactive
Examples of reactive chemicals would include, but not be limited to:
Water reactive chemicals.
Pyrophors, which react with air.
Peroxide forming chemicals, which form
shock sensitive explosives.
ETHER
See tables 5, 6 and 7 of the chemical hygiene plan for
partial lists of reactive chemicals.
19
20. Chemical Storage – Reactive
Consult the MSDS and labels for storage information.
Bring only quantities needed for immediate use into the
laboratory.
Date all reactive chemicals as soon as they are received.
Do not open material after the expiration date.
20
21. Chemical Storage – Reactive
Store pyrophoric chemicals away from flammables.
Store perchloric acid away from reducing agents.
Store perchloric acid bottles in glass or ceramic trays.
Store peroxidizable materials away from heat and light.
21
22. Chemical Storage – Reactive
Store water reactive chemicals away from all
sources of water or in water tight containers.
Store thermally unstable chemicals in approved
refrigerators.
Consider explosion relief boxes for highly sensitive
materials.
Restrict access to the storage area.
22
24. Transporting Chemicals
If chemicals are transferred to a second container, make
sure the new container is labeled with the chemical name.
Use secondary containers, with handles, made of rubber,
plastic or metal.
Secondary containers should be large enough to contain all
of the chemical contents.
24
25. Transporting Chemicals
Make sure the pathway is clear of obstructions and tripping hazards.
Plan ahead for spills.
Transport only the quantity needed to complete the experiment.
Use sturdy carts when transporting heavy containers or transporting
over long distances.
25
27. Chemical Manipulation
Be familiar with chemical properties and products of chemical
reactions.
Be prepared for chemical spills and clean up spills immediately.
Plan ahead – have apparatus and associated equipment ready
before chemicals are used.
Use the appropriate equipment, such as funnels, beakers and
spatulas when transferring chemicals.
27
28. Chemical Manipulation
Use chemical fume hoods to control exposure as chemicals
are transferred.
Use chemical fume hoods to control exposure during
the experiment.
Wear the appropriate personal protective equipment
(chemical splash goggles, gloves, etc.).
Have disposal containers ready ahead of time.
