41
Chemical Storage and
Incompatibilities
• Always return chemicals to their proper place and
store them compatibly.
• Hazardous liquids must be stored in secondary
containers such as trays or buckets
– Remember to store incompatibles in separate trays.
– Separate acids from bases, oxidizers from organic materials
such as combustibles/flammables/reducing agents etc.
• It is CRITICAL that you remember nitric acid will react violently
with organic materials such as acetic acid!
• Always use a “bottle carrier” or other secondary
containment carrier when transporting any
chemicals to or from the lab.
42
Chemical Storage and
Incompatibilities 2
• Watch out for flammable materials such as alcohols,
acetone, ethers etc. and keep them away from
ignition sources.
• NEVER store them in standard refrigerator/freezers!
• Regular refrigerators contain ignition sources (interior lights
defrost cycles) that can ignite flammable vapors.
• If you must keep your flammables cold, store them ONLY in special
“Flame-rated” refrigerators. Read the labels on the refrigerator so
you know what kind it is. If you open a bottle of ether, THF, etc.,
don’t forget to write the “opened” date on it as old ether may
form explosive compounds.
43
Chemical Wastes
• Most labs have several DIFFERENT waste containers.
• MUST make sure you know which container is the correct one
for your waste!
– Otherwise you could cause a fire, explosion or some other unwanted
chemical reaction.
• Containers must not be overfilled or accumulated for greater
than 6 months.
• Waste containers must be kept closed when not in use.
• DO NOT FILL A WASTE JUG MORE THAN ¾ FULL!!!
• It is everyone’s responsibility to NOTIFY CNSM SAFETY WHEN
A CONTAINER IS ¾ FULL.
– A replacement waste container may be available through CNSM
Safety.
44
Double Containment
Use for storage, transport of
Chemicals, including Waste
45
Chemical Wastes-You must affix a
yellow label to all waste containers
Correct application
Incorrect application
46
Acids and Bases
• Watch out for these corrosives as they can
cause severe burns and blindness.
• Never mix acids and bases in a common waste
container, or it may blow up!
• Use caution when adding concentrated acids
or bases to a solution.
– "Do what you ought'er, add acid to water".
• Neutralize tiny acid spills/drips (NOT injuries)
with bicarbonate solution.
47
Toxins
• Many of the reagents used in the lab are toxic
poisons.
• Ingestion, inhalation, and skin contact must be
avoided.
– Even small amounts of some chemicals can kill
immediately.
• Instructors will provide specific
safety/handling warnings as these materials
are introduced into the lab
48
Carcinogens
• Some chemicals may be classified as
carcinogenic (capable of causing cancer) in
addition to the other hazardous properties
– e.g. Benzene is a flammable liquid, is toxic, but
also can induce leukemia with extended exposure
• CAL/OSHA designates which chemicals must
be labeled as Carcinogen. See the CNSM
Safety Manual for the current list.
49
Radioactive Materials
• Typically not used in teaching labs
• Use of Radioactive Materials requires special
training through the Radiation Safety Office
50
Biohazards
• Some lab classes use pathogenic agents and
thus generate Biohazardous waste
• Special training an materials handling
required for use of such materials
• Items contaminated with human blood/blood
products must be collected in specific RED
medical waste containers
• Contact CNSM Safety at 5-5623 if you use any
of these materials

52
Scientific Glassware
• If glass tubing or a thermometer must be
inserted in a rubber stopper or cork,
LUBRICATE IT so it goes in easily.
• If you don’t it may break off and cut you!
53
Handling and Reporting of
Chemical Spills
• Call CNSM Safety before cleaning up
significant spills or spills which you do not feel
capable of addressing safely.
• Once remediated, report the spill on the
CNSM Incident Form.
• Call 911 and/or pull the fire alarm if necessary
to address a spill that may impact others in
the building.
54
Broken Glass and Other Sharp
Items
• Broken glass must be cleaned up promptly, but
NEVER put sharp items in the regular trash!!
• Put them in the special “Broken Glass” box.
• When full, tape shut and place directly in dumpster.
• Do not overfill and do not let the box get wet or too
heavy.
• If the broken glass is contaminated with a hazardous
material, package and label it as hazardous waste.
• Needles must be discarded into approved needle
boxes (sharps containers).

56
Water Reactive Chemicals
• Water Reactive(also air-reactive) chemicals
are especially dangerous
• You will be alerted and given special
instruction if such materials are introduced
into the lab.
57
Oxidizing Chemicals
• Oxidizing Chemicals (“oxidizers”) such as hydrogen
peroxide, potassium nitrate and many chemicals
whose names end in “ate” or “ite”) are especially
dangerous
• May ignite or form explosive compounds on contact
with organic solvents, materials such as flammables,
combustibles, or other reducing materials, OR
reducing agents such as metals etc.
• Oxidizers may not be mixed with or stored beside
these materials.
58
Oxidizing Chemicals
• Supervisors must communicate special
instruction if oxidizers are to be handled.
• Remember, watch out for nitric acid, when
concentrated, it is a very strong oxidizer and
will react violently with organic materials such
as acetic acid!
59
Reproductive Toxins
• Some common chemicals (once in the body)
target male and/or female reproductive
systems or developing fetuses.
• As in the case of the toxic and carcinogenic
chemicals, it is imperative that everyone in the
lab/workplace strive to avoid exposure to the
chemicals through use of the fume hood,
gloves etc.
60
Reproductive Toxins
• Some low level exposures may be
unavoidable.
• Anyone with concerns about chemical
exposures at CSULB can take the list of
workplace chemicals to their medical doctor
to consider the best course of action.
61
Use and Handling of Compressed
Gas and/or Liquefied Gas
62
Use and Handling of Compressed
Gas and/or Liquefied Gas
• Only personnel who have completed CNSM
Gas Cylinder Safety Training may
– Move gas cylinders
– Hook up regulators
– Work with Liquid Nitrogen
– Work with dry ice
63
Equipment Hazards
• Some equipment is dangerous if improperly
used (paper shredder, lasers, centrifuges etc.)
• If you don’t know how to use the equipment
properly, ask before using the equipment
• Supervisors shall ensure that appropriate
training and supervision is provided.
64
Equipment Hazards
--Autoclave--
Autoclaves are dangerous equipment items that
Require specialized training.
65
Work Area Hazard
--Slips, Trips and Falls-• Slips, trips and falls account for a large proportion of workplace injuries
and fatalities.
• Most are caused by hurried or careless work habits, damaged or slippery
(often wet) surfaces, obstructions in walkways, poor visibility or unsafe
use of stairs or ladders.
• Good practices to avoid slips, trips and falls include proper planning of
work activities, promptly cleaning up water or other spills, maintain tidy,
well kept work areas, avoid leaving tools or other materials on floors,
promptly reporting lighting outages to Facilities Management (5-4357) for
repair and not carrying loads large enough to obstruct vision up or down
stairs. Only use ladders in good condition and during use fold them out
completely, face the ladder when climbing, keep weight centered and
keep 3 out of 4 limbs on ladder at all times. When using temporary
extension cords, position equipment to avoid crossing walkways or use
cord protectors.
• Report any potential slips, trips or fall hazards to your supervisor or CNSM
66
Safety immediately.
Laboratory Security Regulation
• All laboratories in the CNSM are bound by the
College Lab Security Regulation which can be
found here:
http://www.csulb.edu/colleges/cnsm/faculty/
documents/CNSM%20Lab%20Security%20124-12.pdf
• Make sure you are familiar with the regulation
and that your name is added to the
Authorized Personnel list as appropriate
67
