Title: MODULE 2
1MODULE 2
- OSHA Hazard Communication
2Module 2 OSHA Hazard Communication Introduction
- Federal rules and regulations that apply to the
propane industry are published in a series of
books called the Code of Federal Regulations
(CFR). An important section pertaining to the
propane industry is OSHA's Hazard Communication
Standard, which is found in Title 29 of the CFR
1910. This regulation is commonly referred to as
the HazCom Standard. - These regulations exist to protect employees of
chemical manufacturers, importers, distributors,
and any company whose work involves hazardous
chemicals. - After completing this module, you will be able
to - Understand what a Hazardous Chemical Inventory
is. - Identify the sections of a Material Safety Data
Sheet (MSDS). - Explain proper labeling procedures.
- Identify the regulatory requirements of your
employer's written hazard communication program.
3LESSON 1
- Hazardous Chemical Inventory
4Hazardous Chemical Inventory Introduction
- To protect yourself on the job, you must know
what chemicals are being used or stored by your
company. To ensure safety in the workplace, OSHA
requires your employer to maintain a Hazardous
Chemical Inventory, which includes - All hazardous chemicals known to be present.
- Hazardous chemicals that may be transported
off-site. - Hazardous chemicals stored away from the
mainplant. - Your employer is also responsible for informing
you where to find the Hazardous Chemical
Inventory at your workplace, and who is
responsible for maintaining the inventory. - After completing this lesson, you will be able
to - Identify the different types of chemical hazards.
- Explain how a chemical is placed on the Hazardous
Chemical Inventory.
5Defining Chemical Hazards
- According to OSHA, a chemical classified as
hazardous must have a physical or health hazard
associated with its use. Here is how the two
hazards are defined - Physical HazardA physical hazard results from a
chemicals physical properties and immediate
risks in handling it. For example, certain
chemicals may be explosive or flammable and
require you to take extra precautions to avoid
sources of ignition. - Health HazardA health hazard can make you ill.
The effects can be either immediate, such as a
chemical that causes a burn or rash, or they can
be long-term or chronic, such as lung cancer
after years of working with asbestos. - In some cases, a chemical may present both a
physical hazard and a health hazard. The
Hazardous Chemical Inventory is to identify these
hazards so you can determine how to safely handle
the chemicals you work with.
6Hazardous Chemical Inventory
- The following steps explain how a chemical is
placed on the Hazardous Chemical Inventory - The manufacturer or importer evaluates every
chemical for hazardous properties. - The hazards found are listed on container labels
and MSDS provided to your company. - Your company designates someone to review the
information and update the Hazardous Chemical
Inventory. - Any chemical with a hazard warning label must be
listed. There may be one hazardous chemical list
for an entire building or separate inventories
for each work area. - Some common household chemicals found in the
workplace, such as cleaning solutions, aerosols,
and wasp spray, do not have to be listed on the
Hazardous Chemical Inventory. You should,
however, always follow any safety precautions
specific to those chemicals.

8LESSON 2
- Material Safety Data Sheets
9Material Safety Data Sheets Introduction
- A Material Safety Data Sheet (MSDS) provides
information about chemical hazards. Anyone who
might come into contact with the hazardous
chemical should read about potential dangers and
how to safely handle the product. - Each chemical is evaluated for potential hazards
by the manufacturer or importer. This information
is then placed on an MSDS. The MSDS must be
readily available in any work area where
employees handle or may come into contact with
hazardous chemicals. - The MSDS must be updated when significant changes
are made to the chemical compound or previously
unknown health and physical hazards are
discovered. - After completing this lesson, you will be able
to - Identify why and how an MSDS is used.
- Identify the different sections of an MSDS.
10The Purpose of an MSDS
- An MSDS is a required document that informs
employees of the chemical nature of materials
they work with. MSDSs must be easily accessible
at all times in any work area where hazardous
materials are present. Your supervisor should
inform you where the MSDSs are located and who is
responsible for keeping them up-to-date. - Read the MSDS for each chemical you are using and
pay special attention to the fire, health, and
safety risk sections. You should also consult
your companys Personal Protective Equipment
(PPE) policy for further information on how to
best protect yourself. - Hazardous chemical distributors are required to
provide an MSDS upon request. If you cannot find
an MSDS for a certain chemical, inform your
supervisor immediately so the missing document
can be obtained.
11How to Read and Understand an MSDS
- Although each MSDS may look a bit different, they
must provide the same information. An MSDS must
explain, in English, how to safely use, handle,
and store a hazardous chemical. Other important
safety information is provided on an MSDS to
protect you and the people around you. This
knowledge can also save valuable time in the
event of an accident or incident. - To ensure your safety, it is important to know
and understand all of the sections of an MSDS
prior to working with any hazardous chemical.
Lets review each section of an MSDS in detail.
The example may not look specifically like your
companys MSDS, but it will contain the same
basic information.
12Section 1 Chemical Product and Company
Identification
- May also be called Product Information,
Identification, Chemical Identification, or
Material Identification. This section commonly
lists the product name, its chemical name, family
or formula, and any other trade names the
chemical is known by. Other information found in
this section may include - The name, address, and telephone number of the
manufacturer, importer, employer, or other party
responsible for the chemical. - The emergency phone number in case of an
accident. - The DOT hazard class and shipping name.
13Section 2 Composition and Information on
Ingredients
- May also be called Hazardous Ingredients. This
section of an MSDS lists the chemicals harmful
ingredients and the percentage amount of each. It
may also list how much of the chemical you can be
exposed to safely. This amount is called either
the Permissible Exposure Limit or the
Threshold Limit Value. - The Permissible Exposure Limit (PEL) is the
maximum concentration of a chemical someone can
be exposed to safely. - The Threshold Limit Value (TLV) is the
concentration of a chemical substance in the
atmosphere that is considered nonhazardous under
normal work conditions. These values are
established by the American Conference of
Governmental Industrial Hygienists.
14Section 2 Composition and Information on
Ingredients, cont.
- PEL and TLV are measured in parts per million, or
PPM. The lower the PPM, the more hazardous the
chemical is. For example, a chemical with a PEL
of 1 ppm is far more toxic than a chemical with a
PEL of 150 ppm. Both PEL and TLV are based on
exposure during a typical 8-hour work shift. - NOTE If Trade Secret appears on an MSDS, it
means the manufacturer is exercising its right to
avoid releasing sensitive product information.
However, in an emergency, this information must
be provided immediately to your company,
emergency responders, or any healthcare
professionals involved.
15Section 3 Hazards Identification
- May also be called Toxicology and Health
Information. This section identifies the
potential physical and health hazards of the
chemical and how to protect yourself while
working with it. It also describes the symptoms
of overexposure and other potential health
effects. - These descriptions may include
- PEL and TLV (if not listed in the hazardous
ingredients section). - How the substance enters the body, also known as
Routes of Exposure. - Medical conditions that may be aggravated by
exposure. - Whether the substance is acarcinogen
(cancer-causing).
16Section 4 First Aid Measures
- This section typically lists first aid and
emergency information specific to exposure to
this chemical. It gives exposure information and
treatment suggestions to help emergency
responders. - This section also states what to do if a
chemical enters your body through - Inhalation.
- Eye contact.
- Skin contact.
- Ingestion.
- Different hazardous chemicals will require
different emergency and first-aid procedures if
overexposed or ingested. Read this section for
any hazardous chemicals you work with or may be
exposed to. - NOTE If your physician requires information
about the chemicals you are or may be exposed to,
you should provide him or her with the MSDS for
those chemicals.
17Section 5 Fire-Fighting Measures
- This section describes flammability information
such as Flash Point and ignition temperature. - Flammable liquids have a flash point below100
F. - Combustible liquids have a flash point at or
above 100 F. - The chemicals flammability limits, expressed as
a percentage of the fuel/air mixture, are also
listed. - In addition, this section describes how to safely
extinguish a fire involving a particular
chemical, including the type of fire extinguisher
you should use. - Remember, fire-fighting techniques are important
even if a hazardous chemical is not directly
involved. It is always critical to stop fires
from spreading to sensitive storage and staging
areas.
18Section 6 Accidental Release Measures
- May also be called Spill or Leak Procedures.
This section lists the proper disposal and
containment methods for a chemical and how it
should be cleaned up in the event of an
accidental spill or leak. This may include - Measures to protect the environment.
- Methods and materials for cleaning up the spill
such as using sand, sawdust, or other absorbent
materials.
19Section 7 Handling and Storage
- This section lists additional precautions for
safely using and handling the chemical. This may
include - Required distances from flammable, combustible,
and other hazardous materials in the area. - Precautions on how to safely move or transport
the chemical. - General storage precautions.
- Container sealing requirements.
- Temperature requirements for storage.
- Because many workplaces have different storage
considerations and hazards on site, be sure to
read your company-specific MSDS for the chemical
you will be working with.
20Section 8 Exposure Controls and Personal
Protection
- May also be called Exposure Control Methods.
This section lists protective measures to follow
when handling the chemical, such as the PPE
required during either normal use or in an
emergency. - You must wear appropriate PPE to protect yourself
when working with chemicals that present health
hazards. You must make sure you take proper
precautions at all times when working with
hazardous chemicals in order to protect yourself
from exposure. - More information about PPE can be found elsewhere
in this training program. In addition, you should
always consult your companys PPE policy for any
further instructions.
21Section 9 Physical and Chemical Properties
- May also be called Physical and Chemical
Characteristics. This section lists a chemicals
physical characteristics and may include the
following - Boiling Point The temperature at which a liquid
changes to a gas (vapor) at normal atmospheric
pressure. - Specific Gravity of Vapor Whether or not the
vapor is lighter or heavier than air. - Specific Gravity of Liquid Whether or not the
liquid is lighter or heavier than water. - Vapor Pressure The pressure produced bythe
vapor on its liquid in a closed system. - Expansion Ratio The ratio of the increase in
volume of a specific amount of liquid when it
changes to a vapor. - Solubility in Water The rate at which the
product will dissolve in water at room
temperature.
22Section 9 Physical and Chemical Properties,
cont.
- Appearance and Odor The appearance and smell of
a material. - Percent Volatile How much of the chemical
evaporates at room temperature. - pH The measurement of acid versus base of a
solution on a scale of 1 to 14. - Odorant Warnings Identifies the particular smell
and attributes of any odorant used. - It is important to always know the physical and
chemical properties of all hazardous chemicals
you work with.
23Section 10 Stability and Reactivity
- This section provides information on the
stability of the chemical and how it reacts under
certain conditions. This information helps you
avoid dangerous situations caused by improper
storage or handling of a hazardous chemical. - Information in this section may include
- Incompatibility with other substances, chemicals,
or materials that might cause the chemical to
burn, explode, or release dangerous gases. - Whether the chemical will be stable or unstable
while in use, storage, or through potential
misuse. - Hazardous by-products of the chemicals
decomposition.
24ANSI MSDS Sections
- The American National Standards Institute (ANSI)
published a standard called Hazardous Industrial
Chemicals, which recommends MSDS preparers use a
common format. This format includes the
OSHA-required sections just reviewed and these
six additional sections - Toxicological Information Identifies how lethal
the chemical is if it enters your body. - Ecological Information Explains the effect the
chemical has on the environment if released. - Disposal Consideration Contains information on
disposal methods and waste classification.
25ANSI MSDS Sections, cont.
- Transport Information States the shipping
information for the chemical, including
packaging and identification requirements for
transport. - Regulatory Information Lists federal, state,
and local requirements. - Other Information Includes disclaimers,
references, and creation and revision dates. - These sections are not required by OSHA, but some
or all may be included on an MSDS. Although they
are not widely used, it is recommended that you
review these sections, if present, to complete
your understanding of the chemical.

28LESSON 3
29Labeling Introduction
- OSHA requires the manufacturer, importer, or
distributor to evaluate each chemical it produces
and determine potential hazards. After a chemical
has been evaluated, its container must be
labeled, tagged, or marked. The type of container
and the amount of chemical stored within the
container also defines how it will be labeled. - The purpose of a hazard warning label is to
identify throughwords, symbols, or pictures - The chemical name.
- The name and address of the chemicals
responsible party. - Any hazards pertaining to the chemical.
- For more detailed information, always check the
MSDS. - After completing this lesson, you will be able
to - Explain why and how labels are used.
- Identify what information must be included on a
label. - Identify labeling and relabeling responsibilities.
30OSHA Labeling Requirements
- There are a number of ways to comply with OSHAs
labeling requirements. Any type of label is
acceptable as long as it conveys the information
clearly. Labels may be written in multiple
languages, but must provide the required
information in English. - Regardless of the type of labels being used,
OSHA- compliant labels must - Be easy to spot and clearly legible.
- Not obstruct any required markings.
- Be placed against a background of contrasting
color. - OSHA labels must include the identity and
appropriate physical and health hazard warnings
that will be useful to employees working around
the chemical. - Lets explore the different labeling systems that
can fulfill these requirements.
31Uniform Labeling Systems
- OSHA requires all containers of hazardous
chemicals to be labeled. The purpose is to alert
anyone who may come into contact with the
container about potential hazards and how to
handle that chemical safely. Although OSHA has
specific requirements for labels, there is no
standard OSHA label. - To help companies comply with OSHA regulations,
some common uniform labeling systems have been
developed by DOT, ANSI, the National Fire
Protection Association (NFPA), and the National
Paint and Coatings Association (NPCA). - No matter what labeling system is used, it is
important that you scan the products packaging
for warning information. Read this information
carefully and contact your supervisor if you have
questions.
32DOT Shipping Labels
- OSHA requires that all hazardous material
containers that are to be transported in commerce
be labeled according to DOT regulations and
include the proper shipping name and material
hazard class. - These shipping labels may use colored diamonds,
numbers, words, and pictures to identify and
describe potential hazards. - Containers that remain at the workplace do not
fall under DOT jurisdiction and are not required
to comply with this labeling standard. - DOT requirements for hazard identification and
shipping labels will be discussed in detail later
in this course.
33ANSI Labels
- The ANSI labeling system uses colors and signal
words to communicate the degree or level of
hazard. This system isused frequently and can be
seen in everyday places. - One example of an ANSI label you may be familiar
with is the CAUTION label on an automatic
door. The signal word CAUTION warns of the
possible danger of a minorinjury. The yellow
background color indicates moderate risk. - ANSI uses these signal words
- DANGER Indicates an imminently hazardous
situation which, if not avoided, may result in
death or serious injury. Safety Signs identified
by the signal word DANGER should be used
sparingly and only for those situations
presenting the most serious hazards. - WARNING Indicates a potentially hazardous
situation which, if not avoided, may result in
death or serious injury. Hazards identified by
the signal word WARNING present a lesser degree
of risk of injury or death than those identified
by the signal word DANGER.
34ANSI Labels, cont.
- CAUTION Indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury. CAUTION may also be
used to alert against unsafe practices associated
with events that could lead to personal injury. - CAUTION used without the Safety Alert Symbol
indicates a potentially hazardous situation
which, if not avoided, may result in property
damage. - The background color of signal word labels also
communicates the degree of hazard of a particular
material or situation. - Red Indicates severe risk.
- Orange Indicates serious risk.
- Yellow Indicates moderate risk.
35ANSI Labels, cont.
- When more than one hazard exists on a product, it
is permissible to use one label, provided the
information addresses each hazard and the signal
word/hazard classification selected is based on
the greatest level of hazard. - ANSI labels may also list specific hazards, their
possible consequences, and how best to avoid
them. This information may be communicated
through words or pictures.
36NFPA 704 Labels
- The NFPA 704 standard labeling system identifies
the health, fire, and chemical reactivity hazards
of liquids stored in drums or bulk tanks. - NFPA 704 uses a series of diamonds with colors
and numbers to label hazards. - Colors show the type of hazard
- Blue indicates a health hazard. The contents
could be harmful to your health. - Red indicates a fire hazard. Contents of the
container could be flammable. - Yellow indicates a chemicals reactivity, such as
explosiveness or adverse reactions in certain
situations. - White indicates special instructions that must be
followed to safely handle the chemical.
37NFPA 704 Labels, cont.
- Numbers designate the degree of risk
- 0 Minimal risk.
- 1 Slight risk.
- 2 Moderate risk.
- 3 Serious risk.
- 4 Severe risk.
- For example, a methanol label shows the chemical
has a slight health risk of 1, a serious risk for
flammability, and no chemical reactivity or
special instructions.
38HMIS Labels
- Similar to the NFPA 704 standard, the Hazardous
Materials Information System (HMIS) labeling
system uses colors and numbers to identify
hazards. These labels are intended to convey full
health warning information. - The colored bars on an HMIS label provide
information about the following areas - Blue indicates health hazards.
- Red indicates the degree of flammability.
- Yellow indicates the potential reactivity.
- Orange indicates physical hazards.
- White indicates required personal protection.
- In the third edition of HMIS, the orange colored
bar indicating physical hazards replaces the
yellow colored bar indicating reactivity.
Although both versions are correct, the National
Paint and Coatings Association (NCPA) encourages
companies to follow the most recent standard.
39HMIS Labels, cont.
- HMIS labels also use the numbers zero through
four to convey the degree of hazard, with four
indicating the highest hazard level. - Under health hazards, an asterisk is added to the
rating if the effects could result in a chronic
condition. - A letter in the Personal Protection section of an
HMIS label provides information on the type of
PPE to use when handling this material. - You may find additional information to the left
of the colored bars, such as route of entry,
specifics on health and physical hazards, and
which organs are most susceptible to these
hazards.
40Consumer Labels
- Many propane companies attach a warning label to
cylinders that will be handled by consumers. This
type of label is primarily for customers who will
be handling portable, refillable propane
containers weighing 100 lb or less without
supervision of a trained propane employee. - Consumer labels generally provide hazard
information and operating instructions in clear,
nonindustry specific terms to help the customer
safely handle propane. - Consumer labels vary depending on company policy,
but should clearly indicate both potential
hazards and how to minimize risk. All propane
container labels must be legible.
41Combination Labels
- Sometimes a company will decide that one type of
standard labeling system does not suit its needs
and may develop a label combining multiple
standards with its own additional information.
They must, however, always meet the requirements
set forth by OSHA and DOT. - Within the industry, a combination label may also
be called a 3-in-1 label or 4-in-1 label. - The label in the example combines information
from ANSI, DOT, and NFPA labels, while including
additional details that the company requires.
This label is intended to help customers
understand how to safely connect their propane
cylinder. - Make sure you understand your companys specific
system for labeling.
42Relabeling Procedures
- When a chemical shipment reaches your company, a
designated employee checks for labels before
accepting the shipment. Unlabeled containers must
either be returned to the manufacturer or
relabeled. - The most common reasons for relabeling are
- To replace soiled, unreadable, or missing labels.
- To label smaller containers of product
transferred from a larger container that will not
be used immediately by the same employee who
conducted that transfer. - The chemical being stored within a container has
changed. - Always check to make sure you are complying with
any additional policies your company may have
concerning labeling and relabeling.
43Exceptions to Labeling
- Occasionally, labels are not necessary. The
following are examples where labeling may not be
required. - When chemicals are shipped by cargo tank or
railcar, DOT placards are on the vehicle and
serve as the required DOT hazard warning. More
information on placarding can be found later in
this course. - Federal regulations do not require the labeling
of pipes or piping systems, but some states do.
The recommended industry practice for labeling
propane piping systems is to label the
termination points of various pipes and hoses
with the word Liquid or Vapor. This applies
to both stationary installations and trucks.
44Exceptions to Labeling, cont.
- If smaller containers are for immediate use by
the person transferring the product, there is no
need to label the container. - OSHA hazard communication labels are not required
when using products regulated by other agencies.
However, those other agencies may have their own
labeling requirements. Examples of this exception
could include certain pesticides and consumer
household products you may work with.

47LESSON 4
- Employee Information and Training
48Employee Information and Training Introduction
- As a propane industry employee, it is important
for you to understand that there are a number of
hazardous chemicalsin your workplace. Although
propane is the chemical you will most often be
working with, you should always be mindful of
other chemicals such as solvents, methanol,
gasoline, diesel fuel, and various paint
products that may also pose a risk. - Because maintaining safety in your workplace is
essential, OSHA requires your company to provide
information and training about all hazardous
chemicals you may be exposed to and how to
safely handle them. - After completing this lesson, you will be able
to - Identify the two hazard groups.
- Explain general safety tips for working with
hazardous chemicals. - Explain what is required of your companys
written program.
49Training Requirements
- OSHAs HazCom Standard requires all employees to
be trained on how to work with the hazardous
chemicals involved with their job. It states - Employers shall provide employees with effective
information and training on hazardous chemicals
in their work area at the time of their initial
assignment, and whenever a new physical or health
hazard the employees have not previously been
trained about is introduced into their work area.
Information and training may be designed to cover
categories of hazards (e.g., flammability,
carcinogenicity) or specific chemicals.
Chemical-specific information must always be
available through labels and material safety data
sheets. - Depending on how many hazardous chemicals you
work with, you may be trained on an entire
hazard group (explained later in this lesson)
or on just a specific chemical. Chemical-specific
training works well in the propane industry
because most employees work with only a few
chemicals.
50Training Requirements, cont.
- Do not hesitate to inform your employer if you
feel you need additional training. - Whatever method of training is used, it must
include - How to detect the presence or release of a
hazardous chemical. - The physical and health hazards involved.
- Measures to protect against these hazards and
properly respond in an emergency.
51Hazard Groups
- Training by a hazard group works best when
employees use many different types of chemicals.
Hazard groups are divided into two categories - Physical Hazards Chemicals with physical
properties that can cause harm, such as an
explosive or a flammable gas. - Health Hazards Chemicals that enter the body and
may cause one to become ill. For example, a
carcinogen may cause cancer, and an irritant may
cause damage to the lungs, skin, eyes, or mucous
membranes. - Your company will determine which type of
training you receive based on the nature of your
work and the number of hazardous chemicals you
may be exposed to on the job.
52Working Safely with Hazardous Chemicals
- When working with hazardous chemicals, you must
be aware of whether those chemicals require
engineering controls, such as ventilation and
guards, or administrative controls, such as
regulated areas or danger zones. In either case,
you must reduce your risk of exposure when
working with these chemicals by following your
companys safety rules and by wearing the proper
PPE. - The PPE your company selects must protect you
from workplace hazards, at least at the level
required by law.
53Working Safely with Hazardous Chemicals, cont.
- PPE most commonly protects
- Face and eyes.
- Head.
- Hands and arms.
- Feet.
- Lungs (respiration).
- Ears (hearing).
- Be sure to read the MSDS to determine which PPE
is necessary, and follow your companys own PPE
requirements.
54General Safety Guidelines
- The following are some general safety guidelines
for you to remember when working with hazardous
chemicals - Always wear proper face and eye protective gear.
If you wear prescription glasses, you can use
fitted goggles or prescription eye protection. - Make sure all safety gear is clean and returned
to its proper place after use. - Inspect your PPE regularly. Defective, damaged,
or worn PPE will not protect you. - Wash hands thoroughly after working with
hazardous chemicals. - Refrain from eating, drinking, smoking, or using
personal items in an area where hazardous
chemicals are present.
55General Safety Guidelines, cont.
- Dispose of hazardous chemicals properly. Do not
mix chemical wastes. - Know where emergency shower and eyewash stations
are located and how to properly operate them. - Know your companys policy for handling hazardous
chemical spills or leaks. - Later in this course, you will learn more about
safe work practices, emergency procedures, and
PPE pertaining to hazardous materials. - As always, you are ultimately responsible for
your own safety and should take every precaution
to protect yourself. If you have a question about
a particular situation, always seek the advice of
your supervisor.
56Written Program
- Your company is required to have a comprehensive
written program in place that details how it
protects its workers from hazardous chemicals.
The following information will help you
understand the major elements of a written
program. - The written program must describe
- How your company determines which chemicals are
hazardous. - Your companys labeling system.
- How MSDSs are received and kept.
- The Hazardous Chemical Inventory.
- How hazardous chemical training is provided.
57Written Program, cont.
- The hazardous chemical training section of the
program must include - The name of the person responsible for conducting
the training. - The training methods used.
- The safety precautions to be taught.
- The emergency and first aid training given.
- The type of additional training given for
non-routine tasks. - Always let your employer know if you feel your
training was confusing or incomplete. If you
notice errors within your companys required
documentation, immediately alert the person
responsible for maintaining them.
