HAZCOM TO GHS

(For Workers Recently HazCom Compliant)

THE CHANGES TO THE STANDARD

Presented for National Electrical Safety Month

HazCom to GHS

The previous HazCom standard was designed for chemicals sold in the U.S., but chemicals used elsewhere throughout the world had different requirements for labeling. The new Globally harmonized System (GHS) is a process of labeling that will allow one label and Safety Data Sheet (SDS) to be used worldwide.

HazCom to GHS

Under the previous HazCom standard, employers were required to ensure that employees were made aware of the hazards of chemicals in the workplace and that they were provided with methods for mitigating those hazards. This was provided through written HazCom policies provided by the employer as well as ensuring that the employees had immediate access to the SDS for any and all chemicals in the workplace. This remains unchanged under the new GHS.

Proper Training is the Key

The bulk of the HazCom Standard is unchanged. One of the significant differences is a conceptual one, HazCom was known as the “Right to Know” standard, the GHS is now known as the “Right to Understand” standard. This implies that the employee needs to have a higher level of comprehension and retention. The employee needs to be able to readily identify and repeat certain aspects of the new standard; this was not expressed in the old HazCom standard.

The Significant Changes

Labels • The NFPA and HMIS labels are being replaced with the new GHS label Pictograms • Pictograms have been developed that will identify the type of hazard MSDS • The format of the MSDS is changed which requires all manufacturers to format a standard SDS.

Numbering System • A revised numbering system for hazard classification has be developed

Labels Must:

Not be removed or defaced Be legible Be in English Be prominently displayed Be readily available in work area Be able to add other languages, but must always have English

NFPA RTK - US Labels WHMIS Std – Canada HSID Std - Europe

What must be on a label?

Product Identifier Signal Word Hazard Statement • Name or ID from SDS • Danger • Warning • Nature of hazard • Degree of hazard Pictogram • One of eight required by OSHA Precautionary Statement • Information to prevent adverse effects from exposure Name, address, telephone number • Manufacturer, importer, or responsible party

Example of a label

Hazard Statement

Describes the nature and degree of the hazard: Nature – Corrosive, Asphxyiant, Flammable Degree – Low, Medium, High, Extremely high, etc.

Precautionary Statement

Basically describes how to handle the chemical safely:

• Use gloves, goggles, and apron; • Do not ever open or use near a heat source; • Wash hands thoroughly when done; and • Respiratory protection is required

Workplace Labeling

Each container must have the GHS Shipping label.

If it is not the shipping container, employers may use:

• Words, pictures, symbols or combinations that provide at least general information regarding the hazards.

• Must have other information immediately available.

Portable Containers

No labels required if:

• For immediate use; and • Transferred from labeled container

Immediate Use

Do you remember what immediate use is?

Does the picture show an example of immediate use?

• Why or why not?

Hazard Classifications on SDS

The SDS may have a number for a hazard class • Number will be a 1, 2, 3, 4, or 5 The HIGHER the number the more SAFE the checmical The LOWER the number the more DANGEROUS the chemical

This is confusing since NFPA is the exact OPPOSITE

GHS Hazard Rating

You typically will only find the GHS numbers on the SDS • Just be aware of the difference If you see an NFPA or HMIS label, follow it as you always would.
