GHS Overview

“Globally Harmonized System of the
Classification & Labeling of Chemicals and
Safety Data Sheets”

United Nations guidance for a uniform
(harmonized) hazard communication system
• Initiated at the 1992 United Nations Conference on
Environment and Development (UNCED)

Based on ”major” existing systems
• USA and Canadian systems for the workplace,
workplace, consumers and pesticides
• European Union directives for classification and labeling
of substances and preparations
• United Nations Recommendations on the Transport of
Dangerous Goods.

OSHA rule
Major changes to the Hazard Communication
Standards





Changed “hazard determination” to “hazard
classification”
Changed “MSDS” to “SDS”
Changed definitions to comply with GHS
Labels for shipped containers must have GHS
information
•

Workplace labels may be GHS labels, or other labels that
identify the material and hazards that are as effective as
the GHS labels.
Safety Data Sheets with 16 sections
•
Will include guidance for transportation information and
environmental hazards.
6
OSHA rule

Other OSHA standards will be affected
where applicable (incorporated by reference)
•
New wording on warning signs for asbestos
and other health hazards.
• Affected standards include: HAZWOPER,
Combustible and Flammable Liquids, Welding,
Cutting and Brazing, Chemical Hygiene Plan,
Permit-Required Confined Space Entry, etc.

GHS Overview
 Elements



Harmonized criteria for
classifying substances and
mixtures according to their
health, environmental and
physical hazards
Harmonized hazard
communication elements,
including requirements for
labeling and safety data sheets.

GHS Overview
 Justification


Label requirements differ, requiring multiple
labels for the same product
Hazard definitions are not consistent
• Toxicity, Flammability

Over 100 diverse hazard communication
regulations for manufacturer’s products
globally.
• Regulatory compliance is complex and costly
• Barrier to international trade in chemicals

GHS Overview

Key Guiding Principles of the Harmonization
Process



Protection will not be reduced
Will be based on intrinsic properties (hazards) of
chemicals
All types of chemicals will be covered
12
I. GHS - Hazard Classification

Defined criteria are used to assign a hazard
classification

Physical Hazards
• 16 categories

Health Hazards
• 10 categories


Environmental Hazards
Mixtures

GHS classification guidance for when chemicals are
mixed for in house use or when exported.

GHS - Hazard Classification
 Hazardous
to the Aquatic Environment -

Acute aquatic toxicity

Chronic aquatic toxicity
• Bioaccumulation potential
• Rapid degradability
16
II. GHS - LABELS
 Labels

Symbols (hazard pictograms) with red border
• Examples:
17
GHS - LABELS

Nine Symbols
• Includes
“Environment”
18
GHS - LABELS


Signal Words
• “Danger” or “Warning”
Hazard Statements
• Example: “Toxic if swallowed”

Other
• Precautions, identification, supplier, supplemental
19
GHS Flammability Rating

1 = EXTREME ( FL. Class IA)

2 = MODERATE ( FL. Class IB) “DANGER”

3 = SLIGHT ( FL. Class IC / Comb. Class II) “WARNING”

4 = COMBUSTIBLE ( Comb. Class IIIA) “WARNING”

(No Rating for Combustible Class IIIB or lower)
“DANGER”

GHS - LABELS

GHS - Label Elements for Flammable Liquids
21
NFPA - Flammability
4 = Will rapidly or completely vaporize at normal pressure and temperature, or is
readily dispersed in air and will burn readily.
3 = Liquids and solids that can be ignited under almost all ambient conditions.
2 = Must be moderately heated or exposed to relatively high temperature before
ignition can occur.
1 = Must be preheated before ignition can occur.
0 = Materials that will not burn.
 The
next slide shows the difference, very
slight difference, in regards to the
temperature change from the NFPA
Classes to the GHS flammability ratings.

Example: where the Class IA and IB =
73.0 degrees F and under GHS the rating
of 1 = 73.4 degrees F
 The
other temperature’s are about the
same difference = 0.3 or 0.4 degrees F

hazard communication program as necessary, and provide additional employee
training for newly identified physical or health hazards.

Transition Period Must Comply with either 29 CFR 1910.1200 (the final
standard), or the current standard, or both for all chemical manufacturers,
importers, distributors and employers.
30
The Impact on Safety and IH
Professionals
Become familiar with the new system.
 Collect new SDS’s as provided by suppliers and
incorporate them into the existing MSDS system
(or use a commercial service)
 Get new GHS labels for “shipped containers”



Employers can use other systems for workplace
labeling that are effective as the GHS labels.
Inform employees about new labels and SDS by
December 1, 2013.
31
Impact on Chemical Manufacturers
and Distributors

Prepare and use new GHS compatible labels

Prepare and distribute new GHS compatible
Safety Data Sheets

Commercial “authoring” firms are ready and
willing to help
