Globally Harmonized System of Classification and Labeling (GHS)

https://www.osha.gov/dsg/hazcom/index.html

Introduction/Background

• OSHA = Occupational Safety and Health Administration

• HCS = Hazard Communication Standard

• GHS = Globally Harmonized System

• Changes

– Use of new labeling elements

– Standardized SDS format (formerly Material Safety Data Sheets)

Introduction/Background

“A globally-harmonized hazard classification and compatible labeling system, including material safety data sheets and easily understandable symbols, should be available, if feasible, by the year 2000.”

Myths

1. The GHS affects only pesticides

2. GHS is regulated under FIFRA and FDACS

GHS addresses all hazardous substances

GHS is regulated under OSHA

What is the GHS?

• The first compliance date of the revised HCS is December 1, 2013

So, why the change?

• To align with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) adopted by 67 nations

• To provide a common and coherent approach to classifying chemicals

• Reduce confusion, facilitate training, and help address literacy problems

So, why the change?

• No country has the ability to identify and specifically regulate every hazardous chemical product

• For example, in the United States, there are an estimated 650,000 such products

• Adoption of requirements for information to accompany the product helps address protection needs

So, why the change?

• Many different countries have come to the same conclusion about using information dissemination as a regulatory means to address chemical hazards

• While similar, they are different enough to require multiple labels and safety data sheets for the same product in international trade

So, why the change?

• Countries with systems have different requirements for hazard definitions as well as information to be included on a label or material safety data sheet

• A product may be considered flammable or toxic in one country, but not in another to which it is being shipped

• These differences impact both protection and trade

So, why the change?

• In the area of protection, users in countries that don’t have specific requirements may see different label warnings or data sheet information for the same chemical

• In the area of trade, the need to comply with multiple regulations regarding hazard classification and labeling is costly and time-consuming

So, why the change?

• Small to medium enterprises are effectively precluded from international trade in chemicals due to the regulatory burden of compliance

Benefits of GHS

• Enhance protection of humans and environment

• Facilitate international trade in chemicals

• Reduce need for testing and evaluation

• Assist countries and international organizations to ensure the sound management of chemicals

Effective Dates

The GHS Elements

• Classification Criteria

– Health and Environmental Hazards

– Physical Hazards

– Mixtures

• Hazard Communication

– Safety Data Sheets

Chemical Classifications

• Chemicals will be classified using a harmonized system that provides standardized language for:

– Health Hazard Categories

– Physical Hazard Categories

– Environmental Hazard Categories

Health Hazards

• Acute Toxicity

• Skin Corrosion/Irritation

• Respiratory or Skin Sensitization

• Germ Cell Mutagenicity

• Carcinogenicity

• Reproductive Toxicity

• Specific Target Organ Toxicity – Single Exposure

• Specific Target Organ Toxicity – Repeated Exposure

• Aspiration

• Simple Asphyxiants

Physical Hazards

• Explosives

• Flammable Aerosols

• Oxidizing Gases

• Gases under Pressure

• Flammable Liquids

• Flammable Solids

• Self-Reactive Chemicals

• Pyrophoric Liquids

• Pyrophoric Solids

• Pyrophoric Gases

• Self-heating Chemicals

• Chemicals, which in contact with water, emit flammable gases

• Oxidizing Liquids

• Oxidizing Solid

• Organic Peroxides

• Corrosive to Metals

• Combustible Dusts

Danger! Toxic If Swallowed, Flammable Liquid and Vapor

Do not eat, drink or use tobacco when using this product. Wash hands thoroughly after handling. Keep container tightly closed. Keep away from heat/spark/open flame – No smoking. Wear protective gloves and eye/face protection. Use

explosion-proof electrical equipment. Take precautionary measures against static discharge. Use only non-sparking tools. Store in cool/well-ventilated place.

IF SWALLOWED: Immediately call a POISON CONTROL CENTER or doctor/physician. Rinse mouth.

In case of fire, use water fog, dry chemical, CO2, or “alcohol” foam.

See Safety Data Sheet for further details regarding safe use of this product.

Using Labels in the Workplace

• Storage of chemicals

• First aid

Using Labels in the Workplace

• A chemical may have multiple hazards

• When there are similar precautionary statements on a label, the one providing the most protective information will be included on the label

Safety Data Sheets

• Under the new Haz Com Standard, Material Safety Data Sheets (MSDS) are now called Safety Data Sheets (SDS)

• All SDSs will have a consistent 16-section format

• Employers must ensure that SDSs are readily accessible to employees

Safety Data Sheets

• Section 1 (Identification):

– The product identifier used on the label

– Name, address, and phone number of the manufacturer

– Recommended use of the chemical

• Section 2 (Hazards Identification):

For a mixture that contains an ingredient(s) with unknown toxicity, a statement describing how much (percentage) of the mixture consists of ingredient(s) with an unknown acute toxicity

Safety Data Sheets

• Section 3 (Composition/Ingredients):

– Chemical name

– Common name and synonyms

– CAS number and other unique identifiers

– Impurities and stabilizing additives
