What is GHS?

Posted by in Safety Signs & Labels on July 16, 2014 . 0 Comments.

GHS was created by the United Nations to standardize chemical hazard classification and
communication worldwide. WHMIS has been modified to incorporate the GHS standardized
classification rules, label requirements and safety data sheet (SDS) format.

After implementing GHS, suppliers now must meet the following labelling requirements:

1. Product Identifier: The product name exactly as it appears on the container and on the Safety

Data Sheet (SDS).

2. Signal Words (NEW): “Danger” or “Warning” are used to emphasize hazards and indicate the

severity of the hazard.

3. Hazard Pictograms: Hazard pictograms, determined by the hazard classification of the product.

In some cases, no pictogram is required.

4. Hazard Statements:Brief standardized statements of all hazards based on the hazard

classification of the product.

5. Precautionary Statements:These statements describe recommended measures to minimize or

prevent adverse effects from exposure to the product, including protective equipment and

emergency measures. First aid is included in precautionary information.

6. Supplier Identifier: The company which made or packaged the product, and is responsible for

the label and SDS. Contact the supplier for additional product information.

After implementing GHS, customers now must meet the following labelling requirements:

1. Educate and train workers on the hazards and safe use of products.

2. Ensure that hazardous products are properly labelled.

3. Prepare workplace labels and SDSs as necessary.

4. Provide access for workers to up-to-date SDSs.
