Hazard Communication Standard (HCS)/Globally Harmonized System (GHS)

HCS/GHS Terminal Objective

The students will be able to identify the presence and classification of hazardous materials through documentation and observation.

ENABLING OBJECTIVES

The students will:Identify the impact of Globally Harmonized

System (GHS).

Background

OSHA Final Rule Published March, 2012 Primary focus on 29CFR1910.1200 Hazard

Communication Standard (HCS) (HazCom) Changed many other OSHA standards

HAZWOPER Health Hazard definition changed to match Hazardous Communication Standard

Many of the specific chemical (“1000 series”) hazards defined, sign changes, and notification changes

Definition changes within flammable liquids and other standards

OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)

Ensure chemical safety in the workplace Information about the identities and hazards of the

chemicals must be available and understandable to workers.

OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)

OSHA Standard (HCS) requires the development and dissemination of information: Chemical manufacturers and importers are required to

evaluate the hazards of the chemicals they produce or import prepare labels and safety data sheets to convey the hazard

information to their downstream customers;

Employers with hazardous chemicals in their workplaces must have labels and safety data sheets for their exposed workers train them to handle the chemicals appropriately.

OSHA Hazardous Communication Standard (HCS)(29CFR1910.1200)

Major changes to the Hazard Communication Standard (meet GHS) Hazard classification: Provides specific criteria for

classification of health and physical hazards, as well as classification of mixtures.

Labels: Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram, and hazard statement for each hazard class and category. Precautionary statements also must be provided.

Materials Safety Data Sheets (MSDS) now Safety Data Sheets (SDS): Will now have a specified 16-section format.

Information and training: Employers are required to train workers by December 1, 2013 on the new labels elements and safety data sheets format to facilitate recognition and understanding.

Globally Harmonized System (GHS)

Hazard Communication Standard (HCS) now aligned with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). Provides a common and coherent approach to classifying

chemicals and communicating hazard information on labels and safety data sheets

Primary purpose of revised Standard is to improve the quality and consistency of hazard information in the workplace by providing easily understandable information on appropriate handling and safe use of hazardous chemicals.

Another purpose of update is to help reduce trade barriers Additional Information:http://www.osha.gov/dsg/hazcom/index.html

GHS of Classification and Labeling of Chemicals

Approach to: Defining health, physical, and environmental

hazards of chemicals Creating classification processes that use available

data on chemicals for comparison with the defined hazard criteria

Communicating hazard information, as well as protective measures, on labels and Safety Data Sheets (SDS)

GHS (cont.)

Attempt to create international standard for hazard identification systems

Differences exist internationally and also within nations

GHS (cont.)

For Instance, in the U.S. all of the following have different systems and definitions: Consumer Product Safety Commission (CPSC) Department of Transportation (DOT) Environmental Protection Agency (EPA) Occupational Safety and Health Administration

Flammable/Combustible Liquids - Now

IMO Flammable = 0-140 Degrees

Signal Words

The signal word indicates the relative degree of severity a hazard.

The signal words used in the GHS are “Danger”

for the more severe hazards “Warning”

for the less severe hazards.

Some lower level hazard categories do not use signal words.

Only one signal word corresponding to the class of the most severe hazard should be used on a label.

Statements

Located on label and SDS Hazard Statements

Hazard statements are standardized and assigned phrases that describe the hazard(s).

Precautionary Statements Precautionary information supplements the hazard

information by briefly providing measures to be taken to minimize or prevent adverse effects
