1. PPE
Personal Protective Equipment: What must
be worn when you work in the laboratory.
Eye Protection
Lab Coat
Long Pants
Closed Toed Shoes – no exposed skin around feet
Lab gloves – when required
4
Eye Protection
• Contact lenses are OK as long as glasses/goggles are worn
• Prescription glasses – you must wear goggles over them
• Safety goggles are provided in organic labs in UV irradiating
cabinets
• Eye wash stations are present in all labs
5
Clothing and Foot Protection
• Clothing must cover all exposed
skin including legs/ankles
• Stockings or leggings do not
provide good coverage
• Sandals, flip-flops, Crocs, opentoe and open-top (i.e. ballet flat)
shoes and canvas shoes (i.e.
Toms) are not appropriate.
These are not going to protect
your feet if you drop a piece of
glass with a liquid chemical
reagent in it.

Your PI will send you home to change if you do not
have appropriate shoes or other required PPE.
7
Hand Protection: Chemically resistant
Lab Gloves
✓ 
• Wear gloves of a material known to be resistant to
permeation by the substances in use – nitrile is good for most
of our laboratory classes.
• Inspect each glove for small holes or tears before use.
• When you spill on your glove or tear it, change it immediately.
Throw gloves away any time you take them off.

Karen Wetterhahn
(October 16, 1948 – June 8, 1997)
Dartmouth College
The latex gloves she was wearing
were not resistant to methyl
mercury – it passed through the
glove, through her skin, entered her
blood system and resulted in her
death weeks after the exposure.
9
Use of Gloves
Remove gloves before handling objects such as
doorknobs, telephones, pens, computer
keyboards, pH meter or other electronic buttons,
or phones while in lab. It might be convenient to
have one gloved hand and one ungloved hand to
do procedures where these kinds of things are
used.
• Throw away gloves anytime you take them off.
• You should expect to use several pairs of gloves
in any given lab period.
10
Tie back long hair before entering the
laboratory, don’t wear dangling jewelry.
Yale physics
student Michele
Dufault was killed
in a shop accident
in April 2011 that
would have been
prevented had she
tied her hair back

UCLA Lab Fire: December 29, 2008
Sheri Sangji was using this plastic syringe
to transfer tert-butyllithium. This was not
the correct procedure, because this
compound is well-known to ignite if it is
comes in contact with air. The syringe
plunger dropped out of the syringe and
the reagent ignited. Sheri died January 16,
2009 of severe burns. She was wearing
nitrile gloves but no lab coat. The students
assisting her did not remember to put her
under the safety shower.
12
Lessons from UCLA accident
Lessons: Know the proper procedures for
transferring dangerous reagents. Wear your lab
coat at all times in the lab. Know where safety
shower and other emergency equipment is –
you may need to be the one who needs to be
ready to act when your lab mate is unable to
help himself/herself.
13
2.
Eyewash and Safety Shower:
Know where these are in your lab.
14
Eyewash / Safety Shower
The eyewash
is on the left.
Pull the
handle and a
fountain of
water will
appear that
you can use
to bathe your
eyes.
The safety shower is
on the right. Pull the
handle and water will
start spraying from the
shower head on the
ceiling. There’s no
drain in the floor – we
only do this in
emergencies, because
a flood of water will
have to be cleaned up.
15

3.
Chemical Fume Hoods: You must do
your experiment in the hood if any
of your reagents are flammable,
have harmful fumes or present a
splash or explosion hazard.
18
Using the Fume Hoods properly
This
window/bar
is called
the sash.
If this is not saying NORMAL, then the hood
is not protecting you. Keeping the sash
and sliding panels in proper position keeps this
NORMAL, otherwise the alarm goes off.
If the alarm goes off, you need to reposition
things to the correct positions, then press the
“mute” button to reset the controller.
The sash should never be raised above
the green “operation” level when you
19
are working in the hood.
In use, side-to-side panel
used as shield
Closed, not in use
✓
In use, sash (window) raised
to less than 18 inches
✓
✓
Don’t open side shields
to make one big window.
×
20
• When using a laboratory hood, Check that the airflow is
in the normal range on the digital display
• Turn on the hood light
• Set the equipment and chemicals back at least 6 inches.
• Never lean in and/or put your head in the hood when
you are working. This is worse than doing the
experiment with no hood at all.
• It’s a good idea to put liquid reagent containers in trays
to catch all spills and drips
21
4.
Know the risks of the chemical
reagents you are working with
22
Labels are important
Even if it seems obvious.
In the chemistry lab, nothing is ever obvious.
23
NFPA Diamond
24
MSDS (SDS)
• Provides procedures for handling or working with
that substance in a safe manner
• Includes physical data:
melting point, boiling point, flash point, etc.
• Includes safety data: incompatibilities, toxicity,
health effects, reactivity, storage, disposal:
protective equipment & spill-handling procedures
first aid
25
How to find an MSDS (SDS)
• There are on-line repositories of MSDS that can
be searched by the following methods:
• Common Name
• IUPAC (International Union of Pure and Applied
Chemistry) Name
• C.A.S. NUMBER – (Chemical Abstracts Service) a
number assigned to all commercialized chemicals
available in the US
• The easiest to use is the CAS number, as it is a
unique identifier that isn’t subject to spelling
errors
26
Incompatible materials
• Certain chemicals should not be stored and
cannot be safely mixed with certain other
chemicals due to severe reaction exotherm or
uncontrolled production of a toxic product.
Every lab has a
legible matrix that
lists the general
classes of
materials that
should not be
mixed together:
27
Texas City Disaster of 1947
• Incompatible oxidizer and fuel source mixed
• Worst industrial accident in American history
• Freighter full of ammonium nitrate and fuel oil
(ANFO) exploded, igniting other ships
• 581 dead, entire city devastated
Ship anchor thrown
across city by
explosion
28
Introductory toxicology
• AN MSDS contains valuable information on
the health dangers of the chemicals but often
use concepts and acronyms that are new to
students:
NIOSH
TLV
OSHA
STEL
Mutagenicity vs.
teratogenicity
You need to know what is what to read an MSDS
29
Regulatory agencies and standards
•
•
•
•
•
•
•
Over the last 40 years the US and state governments and various international bodies
have developed regulations and standards that try to improve safety and industrial
hygiene standards including the following:
EPA: Environmental Protection Agency, who have the primary responsibility to ensure
chemicals are used and disposed of in an environmentally sensitive manner
TOSCA: the Toxic Substances Control Act of 1976 regulates which chemicals may be
produced or imported in the US
OSHA: Occupational Safety and Health Administration is the US agency that assures
safe and healthful working conditions by setting and enforcing standards
NIOSH: National Institute for Occupational Safety and Health is responsible for
researching the prevention of work-related injury and illness, and providing guidance
to OSHA
RCRA: the resource conservation and recovery act of 1976 that sets the standards for
chemical waste disposal in this country and oversees the “superfund law” CERCLA
California Proposition 65: The state of California passed a very rigorous law to protect
drinking and ground water from toxic chemicals. It is increasingly the standard for
companies when evaluating chemical safety
All of these regulations have been developed to make the use
and handling of chemical safer, so their impact on lab safety
has been profound
30
Acute and chronic toxicology
• Acute toxin: rapid absorption of the substance
and the exposure is sudden and severe. Normally,
a single large exposure is involved.
– Examples are carbon monoxide, hydrofluoric acid,
hydrogen cyanide and nicotine
• Chronic toxin: prolonged or repeated exposures
of a duration measured in days, months or years.
Symptoms may not be immediately apparent.
– Examples of chemicals of high chronic toxicity include
dimethylmercury, nickel carbonyl, benzo-a-pyrene, Nnitrosodiethylamine, and other human carcinogens or
substances with high carcinogenic potency in animals
31
Carcinogens, mutagens and teratogens
• One of the most significant chronic risks associated with
chemicals is their potential to cause cell mutation and
proliferation.
– Carcinogen: chemicals that can increase the incidence of cancer
in the body
– Mutagen: chemicals that cause mutations in DNA that lead to
hereditary genetic defects in a fetus
• There are two other general classifications that you should
be aware of:
– Teratogen: chemicals that induce non-hereditary malformations
of a fetus
– Sensitizer: chemicals that no reaction in a person during initial
exposures, but further exposures will cause an allergic response
to the chemical
32
Routes of Entry and Allowable
Exposure Limits
• There are four main routes by which hazardous chemicals
enter the body:
– Inhalation: Absorption through the respiratory tract. Most important in terms
of severity.
– Skin absorption.
– Ingestion: Absorption through the digestive tract. Can occur through eating or
smoking with contaminated hands or in contaminated work areas.
– Injection. Can occur by accidental needle stick or puncture of skin with a sharp
object.
• Most exposure standards, Threshold Limit Values (TLVs) and Permissible
Exposure Limits(PELs), are based on the inhalation route of exposure.
expressed in terms of either parts per million (ppm) or milligrams per cubic meter (mg/m3)
concentration in air.
• Other measures of chemical exposure:
• Lethal dose or concentration for 50% of the exposed population (LD50 or
LC50) expressed in mg contaminant per kg of body weight
• Short term exposure limit (STEL or TLV-STEL) is the amount of a substance
you can be exposed to for 15 minutes four times a day

Fire Safety
34
Fire Alarms –
know the location of one close to your lab
35
Fire Extinguishers – we have several in
the labs and in the hallways.
36
37
Types of Fire Extinguishers
This is a special
fire extinguisher
for combustible
metal fires. It is a
type D fire
extinguisher. You
won’t need to
use this unless
you work in a
research lab with
combustible
metals.
Most of our fire extinguishers are ABC.
It contains a dry powder to put out the
kinds of fires we might encounter in the
chemistry labs where we have class.
38
Student Reaction in a Fire
Although we want you to be informed on the operation of a
fire extinguisher, we do not expect you to use it. If a fire is
ignited in your area, the proper STUDENT response is to:
1) Notify everyone in the room
2) If possible shutdown any reaction in progress by removing
heat/energy source and/or pulling plug on power cord
3) Proceed to the nearest exit and pull the nearest fire alarm
4) Evacuate the building
5) Assemble in front of the library or in the YWCA parking lot
for a positive headcount
39
Flammables, combustibles, and
potentially explosive materials
• There are different ways of designating that a chemical is a
fire risk:
• Flashpoint - minimum temperature at which a liquid gives off
a vapor in sufficient concentration to ignite in the presence of
an ignition source
• Combustible liquid - Any liquid having a flashpoint at or above
37.8oC (100 F) but below 93.3oC (200 F)
• Flammable liquid - any liquid having a flashpoint below 37.8oC
• Autoignition temperature - the lowest temperature at which it
will spontaneously ignite in a normal atmosphere without an
external source of ignition, such as a flame or spark
• Explosive - A chemical that causes a sudden, almost
instantaneous release of pressure, gas, and heat temperature.40
Synthesis of explosive material
• In organic lab we often do reactions to add functional groups to benzene
rings. A simple reaction is shown below:
• If a student overcharged the amount nitric acid and overheats the reaction
the following chemical is isolated:
Trinitrotoluene
If this is not handled carefully
there are serious
repercussions:
•
Another risk is the formation of Peroxides – Explosives that can be
generated in lab when organic ethers are heated for a prolonged period in
41
the presence of air.
Working with flames
• Never leave experiments unattended unless
you take special precautions to avoid
accidents and you notify the responsible
individuals.
• Flames are never allowed when flammable
gases or liquids are in use.
• Always alert others before lighting a flame.
• Never leave a flame unattended under any
circumstances.
• Turn off the natural gas at the valve when
you are finished with your work
• In the organic lab, Bunsen burners are rarely
used to either (1) to pull TLC spotting tubes;
or (2) to conduct flame or combustion tests.
Closed valve is
Perpendicular to hose

Gas Cylinder Safety
43
Gas Cylinders
• http://www.youtube.com/watch?v=mReuQCuJNQQ
• A gas cylinder will become a missile if the valve is
broken or cracked.
• For this reason, gas cylinders must always be
securely chained to a wall or a permanent bench in
the lab. The chain should not be loose.
• If a cylinder is not in use or is going to be moved, it
must be capped to protect you and everyone else in
the building.
• Do not attempt to move a gas cylinder until you
have been trained on this important procedure.

Disposal Procedures
46
Broken Glassware
• Always check your glassware and discard any with
chips, breaks, or obvious flaws.
• Throw away broken glassware into special glass waste
containers, NOT the trash.
• Do not overfill broken glass boxes, replace when ¾ full
YES
NO
47
Waste Disposal
• Waste containers are provided for chemical waste
generated in laboratories
• Some things can go down the sink, some can’t.
Always check with your PI.
• Care must be used to avoid mixing incompatible
chemicals such as
– Acids with Bases
– Oxidizers and Flammables
– Water reactive and
aqueous solutions
– Cyanides and acids
48
University of Maryland
September 26, 2011
• Students were conducting an
experiment with nitric acid and sulfuric
acid was added into a chemical waste
container, causing a violent chemical
reaction sparked a small fire in and
near the laboratory chemical
ventilation hood.
• Two female students were injured as a
result
• Sustained first- and second-degree
chemical burns and superficial cuts.
49
Handling Waste in Labs
• Organic liquids like CH2Cl2 (aka methylene chloride,
dichloromethane) & acetone, & TBME & liquid reagents
PUT IN ORGANIC (HALOGENATED) LIQUID WASTE CONTAINER IN
WASTE HOOD
• Aqueous – neutral (not basic or acidic) containing trace organics
PUT IN AQUEOUS WASTE CONTAINER IN WASTE HOOD
• Aqueous – neutral (not basic or acidic) containing NONTOXIC salts
with no trace organics CAN GO IN PUBLIC SEWAR, DOWN THE
DRAIN (Use the “Would I want to swim it rule?”. Yes? Then put it
down the drain. NO? Then put it in the aqueous waste container.)
• Solid chemical – old products, left over starting materials, includes
organic and inorganic
PUT IN SOLID WASTE CONTAINER IN WASTE HOOD
• Solid, non toxic waste (paper towels, notebook pages)
PUT IN TRASH ONLY IF SAFE TO TOUCH WITH BARE HANDS

52
SEVEN must-have habits for lab-work
1.
2.
3.
4.
5.
6.
7.
Be prepared before walking into the lab.
Think about the how and why before doing anything.
Begin with a clean, neat work area; make it so.
Minimize clutter; store book bags, equipment, etc.
Have instructions, pen and notebook available.
Return materials and equipment to proper places.
Make it clean and neat and orderly before leaving.
53
Keep your lab area clean.
×
Throw away
used paper
towels and
used gloves,
immediately.
×
Don’t block the
floor in front of
the
eyewash/shower
station.
×
Don’t leave
things in the
floor because
someone will
trip over it.
Don’t leave
cords dangling
because
someone will
trip over them.
×
54
Don’t put anything on your face or in
your mouth while you’re in lab.
• Take care not to ingest anything in the
laboratory!
• Food, gum, beverages, candy, and tobacco
products are never allowed in the laboratory.
• Don’t apply makeup, chap-stick, lotion, or
anything to your face or hands during lab. Wash
your hands with soap then leave the lab before
touching your face or other exposed skin.
×
55
Stay aware of what’s happening around
you while you’re working in the lab.
• Don’t use any distracting electronic devices
while in laboratory. If you touch your phone
during lab, you’re contaminating it with
whatever chemicals you’ve been working with.
• Do not wear earbuds in the lab. You need to be
able to hear important announcements,
especially in an emergency or when a safety
concern is addressed.
×
56
Chemical storage
• Flammables/combustibles
• Acids
• Bases
• Oxidizers
• Nonreactive (e.g., brine)
57
Mineral Acids – inorganic acids
Mineral Acids can be stored together except for Nitric Acid, which
must be stored by itself because it is also strong oxidizer.
Strong Mineral Acids
• Hydrochloric Acid
• Hydrobromic Acid
• Hydroiodic Acid
• Nitric Acid
• Perchloric Acid
• Sulfuric Acid
Weak Mineral Acids
• Phosphoric Acid
• Boric Acid
• Hydrofluoric Acid
Storing Acids and Bases
• Mineral Acids can be stored in the same
cabinet as Bases, as long as they are physically
isolated from each other.
• If your lab contains some of each of these
categories of acids, you should have the
following separate cabinets:
1. Mineral Acids + Bases
2. Organic Acids
3. Nitric Acid (Strong Oxidizer)
Nitric Acid
• If nitric acid is mixed with a flammable organic
compound, such as acetic acid, the heat from the
oxidation and neutralization reactions is enough
to ignite the flammable material.
• Nitric acid also slowly destroys its red plastic
bottle cap. Always replace with a new red cap.
• Nitric acid may turn yellow over time because of
the release of nitrogen dioxide on exposure to
light. The yellow color does not affect the
product’s usefulness in the school laboratory.
Sulfuric Acid
• Concentrated sulfuric acid is a strong
dehydrating agent. Because of its strong
ability to remove water, it reacts violently with
many organic materials such as sugar, wood,
and paper.
• If sulfuric acid has turned brown, it has
probably been contaminated with an organic
material and its purity should be in question.
Hydrochloric Acid
• Concentrated hydrochloric acid fumes
continuously and cannot be stored without
releasing hydrochloric acid vapor. These fumes
are responsible for most of the corrosion damage
in your chemical storeroom. Storing hydrochloric
acid in a wood or plastic-lined acid cabinet is a
must. Hydrochloric acid fumes will quickly
corrode metal cabinets.
• Hydrochloric acid fumes mixed with ammonia
fumes will react to form ammonium chloride
clouds and possibly toxic chloramines. Open
containers of these two reagents should not be in
the same hood.
HF
• By definition a weak acid
• However - highly corrosive
• Major health hazard
– absorbed quickly though the skin
– severe systemic toxin
– binds Ca in the blood, bones &
other organs & causes damage
to tissues that is very painful &
exposure to 2% of body to conc.
HF can be lethal
– damage can continue for several
days after exposure
63
Chemical Spills
• Notify your PI and your neighbors if you
spill chemicals on the floor or bench.
• Don’t try to clean it up yourself. Your PI
may need to use a specially designed
chemical spill kit.

Procedures and Practices
65
Texas Tech January 7, 2010
• Conducting research funded by the U.S. Department of
Homeland Security on energetic / explosive compounds
• Attempting to produce 100 times more of an explosive
compound than the informal lab limit (100mg)
Lesson:
Follow instructions
in the lab.
66
Process safety
When performing an experiment always consider the
following:
•
– Is the material flammable, explosive, corrosive, or reactive?
– Is the material toxic, and if so, how exposure to the material
occur
– What kind of personal protective equipment or ventilation is
needed to protect myself?
– Will the process generate other toxic compounds, or could it
result in a fire, explosion, etc.?
– Are storage facilities appropriate for the type of materials used?
Can incompatible materials be properly segregated?
– What possible accidents can occur and what steps can be taken
to minimize the likelihood and impact of an accident?
– What are the proper procedures for disposal of the chemical(s)?
As an example of process safety consider distillation:
67
What I Don’t Know Can’t Hurt Me
At a school far, far away; at a time long, long ago; there was an organic student performing
a reaction that required heat. So the student, happily and cheerfully set about to heat the
solution. The procedure stressed the need to prevent loss of material due to boiling off of
solvent during the heating process. The student did not read over all the details carefully,
but did think to cap the top of the apparatus to prevent the solvent from boiling off.
Pleased for having remembered that little detail, the student was shocked and mad when
the instructor saw what had been done and asked, in a rather loud and obnoxious voice:
“What the heck are you doing?” Look at the picture when it pops up and see if you can
identify what it was that had the instructor so upset. When the student was told by the
instructor what the problem was, the student’s response was (this is a true story): “Well I
do not think that matters, what I don’t know can’t hurt me.”
Trust us, you do not want to be that student.

OSHA FACT SHEET
Laboratory Safety Chemical Hygiene Plan (CHP)
OSHA’s Occupational Exposure to Hazardous Chemicals
in Laboratories standard (29 CFR 1910.1450), referred
to as the Laboratory standard, specifies the mandatory
requirements of a Chemical Hygiene Plan (CHP) to
protect laboratory workers from harm due to hazardous
chemicals. The CHP is a written program stating the
policies, procedures and responsibilities that protect
workers (at CofC “workers” includes faculty, students and
staff) from the health hazards associated with the
hazardous chemicals used in that particular workplace.
70
CofC - CHP
Who wrote the CofC CHP?
• Director of Environmental Health & Safety
(with input from faculty & staff)
Where can you find the CofC CHP?
• In the lab
• On Departmental Web Site
71
GHS
• Now that you’ve had an overview of the various
factors that will help you be safe in a lab, we need
to introduce the next generation proposals:
• GHS: the Global Harmonization System
• GHS is being incorporated by OSHA into the
Hazards Communication Standard (HAZCOM) that
ensures people who handle chemicals are
properly trained
• New symbols for labels with universal usage are
being developed:
72
Overview
• OSHA has issued final rule to revise 29 CFR 1910.1200 (Hazard
Communication Standard)
– Details released 3/20/12, final rule to appear in 3/26/12
Fed. Reg.
• Goal is to integrate components of the UN project’s Global
Harmonization Standard (GHS) into HazCom
• Rule modifies MSDS requirements, labeling, classifications,
and requires retraining of all employees.
• Significant opposition to standard from some business groups
due to:
– Inclusion of “unclassified hazards”- altered in final rule, but
legal challenges possible
– Some disputed economic impact estimates (costs of
training, revised labels and MSDSs etc.)
GHS Symbols
Overview
• Hazard classification: Provides specific criteria for
classification of health and physical hazards, as well as
classification of mixtures.
• Labels: Chemical manufacturers and importers will be
required to provide a label that includes a harmonized signal
word, pictogram, and hazard statement for each hazard class
and category. Precautionary statements must also be
provided.
• Safety Data Sheets: Will now have a specified 16-section
format.
• Information and training: The Final HCS will require that
workers are trained within two years of the publication of the
final rule to facilitate recognition and understanding of the
new labels and safety data sheets.

• For labeling, manufacturer/importer must include:
–
–
–
–
–
–
Product identifier
Signal word
Hazard statement(s)
Pictogram(s)
Precautionary statement(s)
Name, address, and telephone number of responsible party
• Once a chemical has been classified, the label preparer can
obtain the relevant harmonized information from Appendix C
• OSHA is maintaining the flexibility for workplace signs and
labels.
– Use of third party hazard rating systems such as the NFPA diamonds
and HMIS is still a valid approach in the workplace
Students must report any injuries,
big or small.
• Report all injuries to the PI. We will not call
emergency services unless the PI determines
it is a serious injury.
• An incident report will be filled out whether it
is small or serious.
79
Injury procedure, continued
• First Aid kits are available in the lab with
band aids and other items for treating small
cuts and burns.
• If it is a serious injury, your PI will call
campus emergency services, 843-953-5611.
Our campus officers will work with the PI
and/or injured student to determine
whether or not 911 EMS should be called in.
80
Once again, the number to call in an emergency is:
843-953-5611
Please take a moment now to program
this number into your cell phone.
81
Report any concerns
• If you have any safety concerns about the lab you
are working in or the people working around you,
you can contact:
– Your lab PI
– Dr. Neal Tonks – Head of the departmental safety
committee
– Dr. Pamela Riggs-Gelasco – Department Chair for
Chemistry and Biochemistry
– Dr. Jim Deavor, Associate Dean of the School of
Science and Mathematics.
