This training explains the recent changes to the OSHA Hazard Communication Standard, including compliance with the Global Harmonization System of hazard identification, container labeling, and Safety Data Sheets.
Elena FracassaEnvironmental Health Specialist at Wayne State University
OSHA has issued a final rule to revise 29 CFR
1910.1200 – the Hazard Communication Standard
Goal is to integrate components of the United Nation’s
(UN) Global Harmonization Standard (GHS) into
Rule modifies Material Safety Data Sheet (MSDS)
requirements, labeling, classifications, and requires
retraining of all employees.
3. Why the Change to Haz Com?
To align with the Globally Harmonized
System of Classification and Labeling of
Chemicals (GHS) adopted by 67 nations
To provide a common and consistent
approach to classifying chemicals
• Reduce confusion and improve
understanding of the hazards
• Facilitate training
• Help address literacy problems
To provide employees with information to
help them make knowledgeable decisions
about chemical hazards in their workplace
5. Who is Affected by Changes?
Manufacturers, Distributors, Importers
Change SDS information and format
Change container labeling
Training employees on changes to:
SDS (new 16-section format)
Recognize and understand hazards:
Information in new SDS format
Pictograms on container labels
Precautionary and hazard statements
6. Effective Dates and Requirements
Requirement(s) Responsible Party
December 1, 2013 Train employees on the new label
elements and SDS format
June 1, 2015 Compliance with all modified provisions
of the final rule except:
December 1, 2015 The distributor shall not ship containers
labeled by the chemical manufacturer or
importer unless it is a GHS label
June 1, 2016 Update alternative workplace labeling
and hazard communication program
as necessary, and provide additional
employee training for newly identified
Transition Period: 12/2012
to the effective completion
dates noted above
May comply with either MIOSHA Part 42,
92 and 430 (final standard), or the
current standard, or both
7. Chemical Classifications
Chemicals will be classified using a
harmonized system that provides
standardized language for:
Health Hazard Categories
Physical Hazard Categories
Environmental Hazard Categories*
*Regulated by Michigan Dept of Environmental Quality (DEQ)
8. Chemical Classifications:
Hazard Class Hazard Category
Acute toxicity 1 2 3 4
Skin Corrosion/Irritation 1A 1B 1C 2
Serious Eye Damage/Eye Irritation 1 2A 2B
Respiratory or Skin Sensitization 1
Germ Cell Mutagenicity 1A 1B 2
Carcinogenicity 1A 1B 2
Reproductive Toxicity 1A 1B 2 Lactation
Specific Target Organ Toxicity – Single Exposure

9. Health Hazard Rankings
GHS ranks health hazards differently
than the National Fire Protection
Agency (NFPA) and Hazardous
Materials Information System (HMIS)
GHS ranks Health Hazard Category 1 as the most
hazardous with Category 5 as the least hazardous
NFPA/HMIS health hazard rating system ranks
health hazards in the opposite direction with 4 being
the most hazardous

New Label Elements:
Symbols called “Pictograms”
15. Label Pictograms
There are 9 pictograms. Only 8 are regulated by
Environmental Hazards (Regulated by DEQ)
20. Labels: Signal Word
These are words used to indicate the severity of the
hazard and alert employees to the potential hazard.
There are two signal words. Only one of these words
will appear on the chemical label:
“DANGER”(more severe hazard)
“WARNING” (less severe hazard)
Not all labels will have a signal word. Some chemicals
are not hazardous enough to require that a signal word
appear on the label.
21. Labels: Hazard Statement
There are specific hazard statements that must appear
on the label based on the chemical hazard
Flammable liquid and vapor
Causes skin irritation
May cause cancer
22. Labels: Precautionary Statements
Precautionary statements describe recommended
measures that should be taken to protect against
hazardous exposures, or improper storage or handling
of a chemical.
Wear respiratory protection
Wash with soap and water
Store in a well ventilated place
Not necessarily a mandate for employees to follow.
24. Labels: Other or Supplemental Information
Other information that may be included on the label:
Hazards not otherwise classified
Route of exposure
Storage and disposal
Hazard prevention and emergency
26. Safety Data Sheets (SDS)
Under the new Hazard
Material Safety Data Sheets
(MSDS) are now called Safety
Data Sheets (SDS).
All SDSs will have a
standardized 16-section format.
Ex: First Aid in Section 4
Employers must ensure that
SDSs are readily accessible to
28. Safety Data Sheet Sections
Section 7 – Handling and Storage

Section 9 – Physical and Chemical Properties
Section 10 – Stability and Reactivity
Section 11 – Toxicological Information
29. Safety Data Sheet Sections
Section 12 – Ecological Information*
Section 13 – Disposal Consideration*
Section 14 – Transport Information*
Section 15 – Regulatory Information*
Section 16 – Other information including date of
preparation of last revision
*Sections outside of MIOSHA jurisdiction but these sections
must be included for a GHS compliant SDS.
OSHA’s HazCom Standard
Purpose: To ensure that employees know about the
hazards of the chemicals in their workplace, including how
to protect themselves from exposures and reduce the risk
of illnesses and injuries related to hazardous chemicals.
The major components are:

OSHA Hazard Communication Standard and
the Global Harmonization System (GHS) Quiz
Take the quiz
Since 1992, the United Nations have been working to create and enhance a globally harmonized system for the classification and labeling of chemicals that can be used by importers, distributers and manufacturers worldwide.
Chemicals must now go through a specific, prescriptive classification process to determine which hazards are present and which hazard and precautionary statements apply. This can be a lengthy process.
Environmental Hazards are not regulated by MIOSHA.
This chart shows the new health hazard classes and the hazard categories that correspond to each of the health hazard classes. Hazard category 1 (or column furthest to the left) is the most hazardous. Hazard categories become less severe as you move to the right in the chart.
Manufacturers, importers and distributers must classify all hazards for their products. GHS health hazards are ranked the opposite of the NFPA/HMIS System. GHS ranks 1 as the most hazardous. NFPA ranks 4 as the most hazardous.
This chart shows the physical hazard classes and the hazard categories that correspond to each of the physical hazard classes. Hazard category 1 (or column furthest to the left) is the most hazardous. Hazard categories become less severe as you move to the right in the chart.
Manufacturers, importers and distributers must classify all hazards for their products.
This is an example of the new label style that is to appear on product labels beginning no later than June 1, 2015.
*Note that the corrosive pictogram used to designate corrosion to metal is the same pictogram used for skin corrosion/serious eye damage/eye irritation under the health hazard classification.
Not all health hazards represented by this pictogram are corrosive to metal so it is important to look for additional information on the label and in the SDS.
Oxidizers are chemicals that can emit oxygen and increase the risk of fire.
In the past, there have been several signal words that may have been used to indicate a hazard like caution, warning, danger.
The GHS permits the use of only 2 signal words: “Danger” and “Warning”. Only 1 of the signal words is permitted to appear on the label based on the classification of the chemical.
Definition of Hazard Statement:
"Hazard statement" means a statement assigned to a hazard class and category that describes the nature of the hazard(s) of a chemical, including, where appropriate, the degree of hazard.
Manufacturers, importers and distributers use the classification system outlined in GHS to identify which statements must appear in the SDS and on the label found in Appendix C.
Definition of precautionary statement:
"Precautionary statement" means a phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling.
The employer is to evaluate the precautionary statements to determine if these need to be followed by employees. This decision may be based on several factors:
How chemical used
Where it is used (ventilation concerns)
How much of the chemical is used (quantity)
Air sampling or testing results (permissible exposure limits)
How long the chemical is used (time)
For example: A precautionary statement may state “Wear respiratory protection”; however, employees may not be required to wear a respirator based on the employer’s evaluation of the factors listed above (how, where, how much, time, pel).
Definition of product identifier:
"Product identifier" means the name or number used for a hazardous chemical on a label or in the SDS. It provides a unique means by which the user can identify the chemical. The product identifier used shall permit cross-references to be made among the list of hazardous chemicals required in the written hazard communication program, the label and the SDS.
This is discretionary or supplemental information that may be provided by the manufacturer, importer or distributer. This information is not required to be on the label; however it will be found in the SDS.
Manufacturers, importers and distributers may begin using the new 16-section format SDS (follows the ANSI standard) during the transition from the 1994 Haz Com standard and the final 2012 Haz Com standard but no later than June 1, 2015. They are required to provide a revised copy of the MSDS/SDS to the employer anytime changes are made.
Employers are required to maintain copies of all SDSs for the chemicals used and/or stored within the work area. They should have a system to ensure all SDSs are present/accounted and to periodically check for the most current SDS (usually based on revision date) when received from a manufacturer, importer or distributer.
The employer is to maintain a copy of the most current SDS and archive prior MSDSs/SDSs. SDSs are to accessible/available to employees.
Section 1, Identification includes product identifier; manufacturer or distributor name, address, phone number; emergency phone number; recommended use; restrictions on use.
Section 2, Hazard(s) identification includes all hazards regarding the chemical; required label elements.
Section 3, Composition/information on ingredients includes information on chemical ingredients; trade secret claims.
Section 4, First-aid measures includes important symptoms/ effects, acute, delayed; required treatment.
Section 5, Fire-fighting measures lists suitable extinguishing techniques, equipment; chemical hazards from fire.
Section 6, Accidental release measures lists emergency procedures; protective equipment; proper methods of containment and cleanup.
Section 7, Handling and storage lists precautions for safe handling and storage, including incompatibilities.
Section 8, Exposure controls/personal protection lists OSHA's Permissible Exposure Limits (PELs); Threshold Limit Values (TLVs); appropriate engineering controls; personal protective equipment (PPE).
Section 9, Physical and chemical properties lists the chemical's characteristics.
Section 10, Stability and reactivity lists chemical stability and possibility of hazardous reactions.
Section 11, Toxicological information includes routes of exposure; related symptoms, acute and chronic effects; numerical measures of toxicity.
MIOSHA Act 154 requires that posters noting the location and receipt of new or revised SDSs be placed in the work area.
Act 154 will be revised to be in compliance with GHS/Haz Com changes. This change may take some time to be effective.
This slide pictures the posters as they will appear with the anticipated change in wording from MSDS to SDS.
29 CFR 1910.1200
The Hazard Communication (HazCom) standard establishes uniform requirements to make sure that the hazards of all chemicals imported into, produced, or used in U.S. workplaces are evaluated, and that this hazard information is transmitted to affected employers and exposed employees.
The HazCom standard is different from other OSHA health rules because it covers all hazardous chemicals. The rule also incorporates a “downstream flow of information,” which means that producers of chemicals have the primary responsibility for generating and disseminating information, whereas users of chemicals must obtain the information and transmit it to their employees.
Employer also required to describe how they will inform employees of the hazards of non-routine tasks (for example, cleaning reactor vessels), and the hazards associated with chemicals in unlabeled pipes.
The amount of the material to which an individual is exposed to is called the Dose.
The dose effects are dependent on the concentration of the material that gets into the body over a period of time, or concentration x time.
The response depends on the dose and the effects on the body. This may lead to irritation, illness or death.
A high concentration for a short period of time is an acute effect.
A continued smaller exposure for a long period of time is a chronic effect.
