The document discusses changes to the Hazard Communication Standard to align it with the Global Harmonized System of Classification and Labeling of Chemicals. The revised standard requires consistent labeling with pictograms, signal words, and hazard and precautionary statements. It also mandates a standardized 16-section format for Safety Data Sheets to better communicate hazard information globally. The changes are intended to improve worker understanding of chemical hazards.

1. The Revised Hazard
Communication Standard
The Globally Harmonized System (GHS) for
Hazard Classification and Labeling
Presented by Oswego County BOCES Safety
and Risk Department

2. Course Objectives
• Inform employees of changes to the Hazard
Communication Standard (HCS).
• Discuss how the Global System of
Classification affects this change.
• Provide employees with transitional training
required by the revised HCS.
• Alert employees to new hazard
classifications, labeling elements and Safety
Data sheet requirements.

3. The New HazCom Standard
• The Hazard Communication Standard, which
gives us the ‘Right to Know’ about chemicals
we use in the workplace has been revised.
• Changes have brought the HCS into alignment
with the Globally Harmonized System (GHS) of
Classification and Labeling of Chemicals.

4. About the GHS
• The Global Harmonized System of Classification is
a system for standardizing the classification and
labeling of chemicals around the world.
• It is a logical and comprehensive approach for:
– Defining health, physical and environmental hazards
of chemicals;
– Creating classification processes that use available
data on chemicals for comparison with the defined
hazard criteria; and
– Communicating hazard information, as well as
protective measures, on labels and Safety Data Sheets
(SDS)

5. Why the GHS Affects Us!
• Every year, the U.S. imports tens of thousands of
chemicals from around the globe.
• In the past, chemical standards, classifications and
labels have varied from country to country.
• Material safety data sheets (MSDS) lacked a standard
format.
• Multiple types of labeling and classifying systems
were confusing to end-users.
• These deficiencies put workers handling imported
chemicals at greater risk.

6. In Other Words . . .
In order to keep you safe, labels and safety data
sheets all around the world will use the same
precautionary statements, pictograms and signal
words to warn you about chemical hazards.

7. RTK vs. Right to Understand
• The original the Hazard Communication
Standard gave us the ‘Right to Know’ about
the chemicals we work with.
• The new Globally Harmonized System gives
workers the ‘Right to Understand’ that
information better.

8. So what has Changed?
• Labeling requirements:
– The revised standard requires information to be
conveyed with quick visual notations to alert the
user, providing immediate hazard recognition.
– Labels must also provide handling instructions so
that users are informed on how to protect
themselves.
• Safety Data Sheet format
– Information is largely the same, but presented in a
consistent user-friendly 16 section format.

9. GHS Label Features
• Labels now must have:
1. Product identifiers
2. Signal words
3. Pictograms
4. Hazard statements
5. Precautionary statements
6. Name, address and phone number of the
manufacturer, distributor or importer

10. Product Identifiers
• How the hazardous chemical is identified.
– Chemical name
– Chemical code number
– Batch number.
• The manufacturer, importer or distributer
must decide on appropriate identifier AND
assure that it is on both the label and Section
1 of the Safety Data Sheet.

11. Signal Word
• Used to indicate the relative level of severity
of hazard and alert the reader to a potential
hazard on the label.
• There are only two (2) signal words:
– DANGER is used for the more severe hazards.
– WARNING is used for less severe hazards.

12. Pictograms
• A pictogram is a symbol that is intended to convey
specific information about the hazards of a chemical.
• There are nine pictograms under the GHS.
However, only eight pictograms are required under the
HCS.
• OSHA required pictograms must have all of the
following features:
– Square set on end (diamond shaped)
– Red frame
– White background
– Black hazard symbol

13. Environment

14. Hazard Statements
• Must describe the nature of a chemical’s
hazards, including the degree of hazard.
• All applicable hazard statements must appear
on the label.
• Chemical users should always see the same
statement for the same hazards:
– No matter what the chemical is.
– Or, who produces it.
4

15. Precautionary Statement
• A phrase that describes recommended
precautionary measures that should be taken for:
– General precautions
– Preventive precautions
– Response precautions
– Storage precautions
– Disposal precautions
• Each precautionary statement has an
alphanumeric code. (Click link below)
• Explore Precautionary Statement and Hazard
Codes

16. Contact Info
• Name, address and phone number of the
chemical manufacturer, distributor or
importer.

17. Product Identifiers
Signal Word
Pictogram
Hazard Statement
Precautionary Statement
Name, Address, Phone
New Label Example

18. Safety Data Sheets
• The word ‘Material’ has been eliminated as a
Hazard Communication descriptor.
• Safety Data Sheets (SDS) contain much of the
same info as MSDSs, but are now presented in
a consistent user-friendly, 16 section format.
