Material Safety Data
Sheet (MSDS)
Introduction
The Material Safety Data Sheet (MSDS) is a
detailed information bulletin prepared by the
manufacturer or importer of a chemical that
describes the physical and chemical properties,
physical and health hazards, routes of exposure,
precautions for safe handling and use,
emergency and first-aid procedures, and control
measures. Information on an MSDS aids in the
selection of safe products and helps prepare
employers and employees to respond effectively
to daily exposure situations as well as to
emergency situations.
The MSDSs are a comprehensive source of
information for all types of employers. There
may be information on the MSDS that is not
useful to you or not important to the safety and
health in your particular operation. Concentrate
on the information that is applicable to your
situation. Generally, hazard information and
protective measures should be the focus of
concern.
In addition to the Glossary at the end of this
manual, Appendix A of the OSHA Hazard
Communication Model Training Program
contains a glossary of terms used on MSDS/s.
Some employers who are not very familiar with
chemical terminology may find this helpful in
reading and understanding MSDS/s.
OSHA Requirements
Employers must maintain a complete and
accurate MSDS for each hazardous chemical
that is used in the facility. They are entitled to
obtain this information automatically upon
purchase of the material. When new and
significant information becomes available
concerning a product's hazards or ways to
protect against the hazards, chemical
manufacturers, importers, or distributors must
add it to their MSDS within three months and
provide it to their customers with the next
shipment of the chemical. Employers must have
an MSDS for each hazardous chemical used in
the workplace. If there are multiple suppliers of
Hazcom Training Manual
the same chemical, there is no need to retain
multiple MSDS/s for that chemical.
While MSDS/s are not required to be physically
attached to a shipment, they must accompany or
precede the shipment. When the
manufacturer/supplier fails to send an MSDS
with a shipment labeled as a hazardous
chemical, the employer must obtain one form the
chemical manufacturer, importer, or distributor
as soon as possible. Similarly, if the MSDS is
incomplete or unclear, the employer should
contact the manufacturer or importer to get
clarification or obtain missing information.
When an employer is unable to obtain an MSDS
from a supplier or manufacturer, he/she should
submit a written complaint, with complete
background information, to the nearest OSHA
area office. (Although written complaints do not
have to be submitted on an OSHA-7 Form, it is
available online at www.osha.gov.) OSHA will
then, at the same time, call and send a certified
letter to the supplier or manufacturer to obtain
the needed information. If the supplier or
manufacturer still fails to respond within a
reasonable time, OSHA will inspect the supplier
or manufacturer and take appropriate
enforcement action.
Sections of an MSDS and Their
Significance
OSHA specifies the information to be included
on an MSDS, but does not prescribe the precise
format for an MSDS. A non-mandatory MSDS
form (see OSHA Form 174 on page 5 of this
manual) that meets the Hazard Communication
Standard requirements has been issued and can
be used as is or expanded as needed. The
MSDS must be in English and must include at
least the following information.
page 14
OSU Hazard Communication
 An identity on the MSDS must be crossreferenced to the identity found on the label.
 The compound's potential for fire an
explosion must be described. Also, the fire
hazards of the chemical and the conditions
under which it could ignite or explode must
be identified. Recommended extinguishing
agents and fire-fighting methods must be
described.
Section II. Hazardous Ingredients
Section V. Reactivity Data
 For a hazardous chemical mixture that has
been tested as a whole to determine its
hazards, the chemical and common names of
the ingredients that are associated with the
hazards, and the common name of the
mixture must be listed.
 This section presents information about other
chemicals and substances with which it
reacts. Information on any hazardous
decomposition products, such as carbon
monoxide, must be included.
 If the chemical is a mixture that has not been
tested as a whole the chemical and common
names of all ingredients determined to be
health hazards and comprising 1 percent or
greater of the composition must be listed.
Section VI. Health Hazards
Section I. Chemical Identity
 The chemical and common name(s) must be
provided for single chemical substances.
 Chemical and common names of
carcinogens must be listed if they are present
in the mixture at levels of 0.1 percent or
greater.
 All components of a mixture that have been
determined to present a physical hazard must
be listed.
 Chemical and common names of all
ingredients determined to be health hazards
and comprising less than 1 percent (0.1
percent for carcinogens) of the mixture must
also be listed if they can still exceed an
established Permissible Exposure Limit (PEL)
or Threshold Limit Value (TLV) or present a
health risk to exposed employees in these
concentrations.
Section III. Physical and Chemical
Characteristics
 The physical and chemical characteristics of
the hazardous substance must be listed.
These include items such as boiling and
freezing points, density, vapor pressure,
specific gravity, solubility, volatility, and the
product's general appearance and odor.
These characteristics provide important
information for designing safe and healthful
work practices.
Section IV. Fire and Explosion
Hazard Data
Hazcom Training Manual
 The acute and chronic health hazards of the
chemical, together with signs and symptoms
of exposure, must be listed. In addition, any
medical conditions that are aggravated by
exposure to the compound must be included.
The specific types of chemical health hazards
defined in the standard include carcinogens,
corrosives, toxins, irritants, sensitizers,
mutagens, teratogens, and effects on target
organs (i.e., liver, kidney, nervous system,
blood, lungs, mucous membranes,
reproductive system, skin, eyes, etc.).
 The route of entry section describes the
primary pathway by which the chemical
enters the body. There are three principal
routes of entry: inhalation, skin, and
ingestion.
 This section of the MSDS supplies the OSHA
PEL, the ACGIH TLV, and other exposure
levels used or recommended by the chemical
manufacturer.
 If the compound is listed as a carcinogen
(cancer-causing agent) by OSHA, the
National Toxicology Program (NTP), or the
International Agency for Research on Cancer
(IARC), this information must be indicated on
the MSDS.
Section VII. Precautions for Safe
Handling and Use
 The standard requires the preparer to
describe the precautions for safe handling
and use. These include recommended
industrial hygiene practices, precautions to be
taken during repair and maintenance of
page 15
OSU Hazard Communication
equipment, and procedures for cleaning up
spills and leaks. Some manufacturers also
use this section to include useful information
not specifically required by the standard, such
as EPA waste disposal methods and state
and local requirements.
Employer Responsibilities
Employers must ensure that each employee has
a basic knowledge of how to find information on
an MSDS and how to properly made use of that
information. Employers also must ensure the
following:
Section VIII. Control Measures
 The standard requires the preparer of the
MSDS to list any generally applicable control
measures. These include engineering
controls, safe handling procedures, and
personal protective equipment. Information is
often included on the use of goggles, gloves,
body suits, respirators, and face shields.
 Complete and accurate MSDS/s are made
available during each work shift to employees
when they are in their work areas.
 Information is provided for each hazardous
chemical.

Training (Comments)
• Training isn't handing out MSDS/s and asking them to read.
• Training should be accompanied by a simple test with
signature, and filed for documentation.
• Training probably occurs in two phases:
1.
General chemical safety, spill response, labeling
procedure, etc. Perhaps film or tape.
2.
Specific work place. Specific labels, MSDS/s,
emergency plans, etc.
• Phase 2 (specific) trainers should be trained and provided
guidelines.
• If decentralized, periodic audits will help.
• Annual retraining or when new hazard is introduced.
• Trainers should not criticize program.
• Training packages are available:
* computer self-paced instruction
* films
* video tapes
• There is no substitute for workplace-specific training.

INTRODUCTION AND GENERAL STATEMENT
1.01 Almost every workplace contains some substances which could pose potential health
problems to employees if exposed to them in concentrations or in a manner not prescribed.
Oklahoma State University recognizes that its employees have the right and need to know the
properties and potential safety and health problems of substances to which they may be exposed.
With this policy, Oklahoma State University intends to ensure the transmission of necessary
information to employees regarding substances in the workplace, pursuant to Title 40, Oklahoma
Statues, Section 401-424 and the Federal Occupational Safety and Health Act Hazard
Communication Standard, 29 Code of Federal Regulations 1910.1200.
1.02 A hazardous substance is defined as any substance that is a physical hazard or a health
hazard, i.e. compressed gases, explosives, flammables, oxidizers, carcinogens, toxins, irritants, or
corrosives. Hazardous substances generally have a Material Safety Data Sheet (MSDS) provided
by the manufacturer.
1.03
This policy is established to:
a.
b.
c.
Ensure compliance with the applicable state and federal standard.
Safeguard the health and safety of employees of Oklahoma State University.
Create guidelines to follow for implementation and maintenance of a hazard
communication program.
1.04 The Hazard Communication Program for Oklahoma State University shall be
administered by the Manager of Environmental Health & Safety Services, whose line of
administrative authority is through the Director of Physical Plant Services. The Hazard
Communication Coordinator has been designated as the Master Record Keeper.
1.05 The OSU Branch Campuses will be responsible for developing and maintaining their own
internal procedures.
CHEMICAL INVENTORY AND MATERIAL SAFETY DATA SHEETS
2.01 Annual updates of the Chemical Information Lists (CIL) beginning with the fiscal year
July 1, 1990, are required. Individual department supervisors shall complete and mail Chemical
Information Lists (CIL) to the Master Record Keeper no later than August 1 of each year. CIL's
must be submitted in alphabetical order and shall be verified for completeness by the appropriate
department head. Each CIL is subject to audit by the Master Record Keeper. The Master Record
Keeper will provide copies of the CIL to the Local Fire Department and the Local Emergency
Planning Committee.
2.02 A master CIL shall be created and maintained by the Master Record Keeper in a manner
that will allow a listing of hazardous substances by building, room, department, and
manufacturer.
Hazcom Training Manual
page 52
OSU Hazard Communication
2.03 Each building on campus shall have a CIL. The CIL shall include a listing of all
hazardous substances present. The Master Record Keeper will develop an overall Building CIL
by combining the individual lists supplied by each department/area in the building.
2.04 Each time a department receives a new hazardous substance, the substance must be added
to the departmental CIL within 30 days. A copy of the CIL, along with the original copy of the
Material Safety Data Sheet (MSDS) for the new substance, must be sent to the Master Record
Keeper.
2.05 Material Safety Data Sheets (MSDS's) provide detailed information on a hazardous
substance. The sheets include information such as product name (hazardous substance),
chemical abstract service number(s), ingredients, physical data, fire and explosion hazard data,
environmental and disposal information, health hazard data, first-aid instructions, and handling
precautions.
2.06 Department Heads must assure that MSDS's for all hazardous substances in the work
place are obtained. A copy of the MSDS's must be kept in the department and be readily
accessible to employees who work with the hazardous substances. The original copies of
MSDS's must be sent to the Master Record Keeper to be placed in the master file. Copies of the
MSDS's should be placed in a filing cabinet, notebook, etc., and marked with an MSDS label
available from the Master Record Keeper.
2.07 Purchase Orders for any hazardous substance, regardless of the quantity ordered, shall
require that an MSDS be obtained. It is the responsibility of the ordering department
(Department Head) to make every effort to obtain an MSDS from the manufacturer. If
difficulties are encountered, the Master Record Keeper can assist.
2.08 Areas that store hazardous substances for distribution to other departments must obtain
MSDS's for these substances and prepare a CIL. When the storeroom sells or transfers a
hazardous substance to another department, the storeroom supervisor must assure that the
receiving department or individual receives a copy of the MSDS. Likewise, if the storeroom
prepares a substance by any process for distribution to another department or individual, then the
storeroom has assumed the role of the manufacturer and must prepare an MSDS for the
substance. The Department Head over the storeroom areas shall assure that the above steps have
been completed.
2.09 Should the supervisor of an area dealing with hazardous substances become aware of any
information that is significant in regard to the health hazard of a substance (that does not already
appear on the MSDS), he/she must add the information to the MSDS within a period not to
exceed 30 days. The supervisor must also report this information to the Master Record Keeper.
The information will be added to the master file and reported in writing to the appropriate state
agency for follow-up investigation with the chemical manufacturer.
SIGNS AND LABELS
3.01 All existing labels on containers of hazardous substances must remain intact. The labels
must be legible and written in English. Where labels are not present or are not legible, a
Hazardous Material Information System (HMIS) label will be affixed to those containers holding
the hazardous substance.
3.02 It is the responsibility of the Department Heads to assure that each container of a
hazardous substance in the workplace is marked, labeled or tagged with the...
Hazcom Training Manual
page 53
OSU Hazard Communication
a.
b.
c.
Common/trade name of the substance.
Appropriate hazard warnings: Health, flammability, reactivity, and personal
protective equipment.
Chemical abstract service number (CAS).
HMIS labels are available from the Master Record Keeper for this purpose.
3.03 Portable containers filled with hazardous chemicals transferred from a labeled storage
container must be labeled if:
a.
The material is not used within the work shift of the employee making the
transfer.
b.
The employee that made the transfer leaves the work area.
c.
The container is moved to another work area and is no longer in possession of the
employee who filled the container.
Labels on portable containers are not required if the employee who made the transfer uses
all of the contents during the work shift.
3.04 Storage tanks must be labeled with the identity of the substances that it contains. The
label must show the health, flammability, reactivity, and physical hazards associated with the
substance. The National Fire Protection Association (NFPA) rating system must be used to show
these ratings.
3.05 Containers used by outside service contractors shall be properly labeled with either a
manufacturer's label or an HMIS label prior to the use of the hazardous substance on A & M
Colleges' property.
3.06 Employees that work in the storeroom areas, where sealed containers of hazardous
substances are received for distribution to other departments, must assure that the manufacturer's
labels are not defaced or removed. If the labels are removed or defaced, follow the procedure
outlined in 3.02 for replacement of the labels. In addition, if a spill or leak occurs in a container
of hazardous substance, the employees should leave the area, go to a place of safety, and call the
Environmental Health and Safety Department for assistance. MSDS's for all substances in the
storeroom must be obtained and be readily accessible to employees for these substances.
3.07 In addition to the labeling requirement for containers of hazardous substances, the area
where the hazardous substance is used or stored must be properly marked. In order to
accomplish this requirement, the Master Record Keeper has obtained the Uniform Laboratory
Hazard Signage (ULHS) system. The signs identify the areas where hazardous substances are
used or stored through pictograph symbols. The signs will warn employees and visitors that
proper precautions should be observed when entering the area. The ULHS signs are available
from the Master Record Keeper.

EXPOSURE
5.01 Exposure of exposed means that an employee is subjected to a hazardous chemical in the
course of employment through any route of entry (inhalation, ingestion, skin contact or
absorption, etc.), and includes potential (e.g. accidental or possible) exposure as referenced by
the MSDS. When the employer discovers that an employee has received a potentially hazardous
exposure to any substance or agent, the employer must immediately notify the employee and take
such steps that may be necessary to provide medical evaluation, monitoring, or treatment.
Likewise, an employee that has received a potentially hazardous exposure to a substance or agent
must immediately notify the employer of such exposure.
5.02 After the appropriate safety and health precautions have been taken, it is the responsibility
of the employee's supervisor to fill out an Employee Exposure Report (EER). EER forms are
available from the Master Record Keeper. The completed EER should be submitted to the
Master Record Keeper (original copy), with a copy retained at the department and a copy
provided to the employee.
5.03 The Master Record Keeper will retain the original EER and send a copy to the Personnel
Services Office. The Personnel Services Office will place the EER in the employee's permanent
personnel file to be retained for the length of employment plus 40 years.
5.04 An affected employee (or designated representative) may make a request to the Master
Record Keeper or employing department for access to copies of the appropriate CIL and MSDS's.
Access to the appropriate CIL and MSDS's shall be granted within a reasonable time, place, and

6.03 Department supervisors shall inform their employees of the requirements of the Hazard
Communication Standard (cover the four stages of the program), any operations in their
department where hazardous substances are used, the location and availability of the MSDS's and
CIL, and a review of the department Contingency Checklist. In addition, the training must cover
the methods used to detect the presence of a substance released and the steps to take after the
release is detected, the physical and health hazards in the department, the measures and
equipment used for personal protection, and the details of the written plan. The training must
occur within 30 days of employment for new employees. Any time a new hazard is introduced
into the workplace, employees must be trained on the hazard; and an annual retraining session is
required for all employees.
6.04 Training and education provided to employees and others must be documented with
detailed records of training maintained by the department. The training records must be kept for

CHEMICAL INVENTORY (ONLINE)
To comply with the Emergency Planning Community Right-To-Know Act (EPCRA), mandated by Federal
law, all chemicals on the Oklahoma State University campus must be inventoried. The law requires that
the local fire department be informed of the types, quantities, and locations of these chemicals. To
accomplish this task, the Chemical Safety Assistant (CSA) program is available online at
http://ehs.okstate.edu/hazcom.
Access to the online CSA can be obtained through EHS by submitting an Access Request form. The
requester must list each room for which he or she is responsible that contains substances that must be
inventoried. Departments can designate one or more persons to have this access.
The CSA requires certain information concerning the chemical, i.e., type, size and number of containers,
location, etc. It must be updated at least annually and whenever a new product is added to the inventory.

"OSU-SPECIFIC" GUIDELINES
CONTINGENCY CHECK LIST
The purpose of the Contingency Check List is to assist in the preparation of a Campus/County-wide
contingency plan in cooperation with the Payne County Local Emergency Planning Committee.
One of the most important items of information requested on the contingency check list is the contact
personnel (who to contact in the event of an actual emergency).
It is important that the form is completed in its entirety, i.e., nearest fire hydrant, storm drains, or drain
inside the building, etc.
Even though no hazardous substances are used or stored in the department, show the evacuation route
to be used for other emergency situations. If no chemicals are used in the department, such as offices,
some questions will not apply; enter N/A.
EMPLOYEE EXPOSURE REPORT
The Employee Exposure Report (EER) was developed to comply with the law and to assure the safety
and protection of all employees at Oklahoma State University.
It is important to answer all questions on the EER after an exposure or potential exposure has occurred. It
is the responsibility of the employee's supervisor or department head to complete the form, not the
affected employee. Once the form is completed, it should be sent to the Environmental Health and Safety
Department. The Employee Exposure Report will be kept on file for a period of forty years after the
employee has left employment at Oklahoma State University.
The completion of the Employee Exposure Report is to protect all employees and is not an admission of
liability.

Frequently Asked Questions
1. What if more than one person is assigned to a lab? How do we tell which items
belong to whom?
A.
They will each have their own username. Any inventory entered under a
person’s name will be belong to that person. Others assigned to the same
room will not be able to see each other’s inventory.
2. What if one person is responsible for an entire lab and needs others to help
maintain the inventory?
A.
The others’ usernames will be attached to the responsible person’s inventory
access. They will be able to log in and work with the inventory of that person.
3. Our department has a Lab Manager, who needs to see the inventory of one or more
labs. Can this be arranged?
A.
Yes. Just let us know if the Manager’s access rights need to be read-only or
not.
4. Our department feels it would be better if one or two people maintained the
inventories for everyone else.
A.
We can set that up.
5. A lab has been moved to another room. How do we update the entire inventory to
show the new room number?
A.
Just let know and we can make the change for you—often the same day.
This works if an entire lab is being moved or just a few chemicals.

TERATOGEN:Substance or agent to which exposure of a pregnant female can result in
malformation in the fetus.
THRESHOLD LIMIT VALUE:Airborne concentration of a material to which nearly all persons can be
exposed day after day, without adverse effects. TLV's are expressed in 3 ways:
TLV-C:Ceiling limit, concentration that should not be exceeded even instantaneously.
TLV-STEL:Short term exposure limit, maximum concentration for a continuous 15-minute
exposure period.
TLV-TWA:Time-weighted average, concentration for a normal 8-hour work day or 40-hour work
week.
THRESHOLD PLANNING QUANTITY (TPQ):Per 40 CFR 302. The amount of material at a facility
that requires emergency planning and notification per CERCLA.
TINNITUS:Ringing sound in the ears.
TOXICITY:Sum of adverse effects resulting from exposure to a material, generally by the mouth,
skin, or respiratory tract.
TOXICOLOGY:Study of the nature, effects, and detection of poisons in living organisms. Also,
substances that are otherwise harmless but prove toxic under particular conditions.
TOXIC SUBSTANCE:Chemical or material that (1) has evidence of an acute or chronic health
hazard, and (2) is listed in the RTECS manual, provided that the substance causes harm at any dose
level; causes cancer or reproductive effects in animals at any dose level; has a median lethal dose
level of less than 500 mg per kg of body weight when administered orally to rats; has a median lethal
dose level of less than 1000 mg per kg of body weight when administered by continuous contact to the
bare skin of albino rabbits; or has a median lethal concentration in air of less than 2000 ppm by volume
of gas or vapor, or less than 20 mg per liter of mist, fume, or dust when administered to albino rats.
TOXIC SUBSTANCES CONTROL ACT (TSCA):Public Law PL 94-469. Found in 40 CFR 700-799.
EPA has jurisdiction. Effective January 1, 1977. Controls the exposure to and use of raw industrial
chemicals not subject to other laws. Chemicals are to be evaluated prior to use and can be controlled
based on risk. The act provides for a listing of all chemicals that are to be evaluated prior to
manufacture or use in the US.
TRADE NAME:Trademark name or commercial trade name for a material given by the
manufacturer.
TRADE SECRET:Any confidential formula pattern, process, device, information, or compilation of
information used in an employer's business and gives the employer an opportunity to obtain an
advantage over competitors.
TWA:Time-weighted average exposure is the airborne concentration of a material to which a person
is exposed, averaged over the total exposure time, generally the total workday (8 to 12 hours).
UPPER EXPLOSIVE (FLAMMABLE) LIMIT (UEL):Highest concentration (highest percentage of the
substance in air) that will produce a flash of fire when an ignition source (heat, electric arc, or flame) is
present.
UNSTABLE:Tending toward decomposition or other unwanted chemical change during normal
handling or storage.

USE:To package, handle, react, or transfer.
UTRICARIA:Nettle rash; hives; elevated, itching white patches.
VAPOR:Gaseous state of a material suspended in air that would be a liquid or solid under ordinary
conditions.
VAPOR DENSITY:Weight of vapor or gas compared to an equal volume of air; expression of the
density of the vapor or gas.
VAPOR PRESSURE:Pressure exerted by a saturated vapor above its liquid in a closed container.
Important facts to remember:
(1) Vapor pressure of a substance at 100F will always be higher than the vapor pressure of the
substance at 60F.
(2) Vapor pressures reported on MSDS/s in mmHg are usually very low pressures; 760 mmHg is
equivalent to 14.7 psi.
(3) The lower the boiling point of a substance, the higher its vapor pressure.
VAPOR:Gaseous form of a solid or liquid substance as it evaporates.
VENTILATION:Circulating fresh air to replace contaminated air.
VERTIGO:Feeling of revolving in space; dizziness, giddiness.
VISCOSITY:Tendency of a fluid to resist internal flow without regard to its density.
