2. Maintenance of Safety Data Sheets (SDS)

Accessible SDS containing detailed information about the properties and hazards of chemicals is vital. The program should specify procedures for obtaining, organizing, and updating these sheets as necessary.

3. Regular Employee Training on Hazard Awareness

Ongoing training sessions are essential for educating employees about the potential hazards associated with the chemicals they work with. The program should outline a schedule for conducting these training sessions and the topics to be covered.

By integrating these components into a comprehensive Hazard Communication Program, employers can effectively fulfil their obligations under the Hazard Communication Standard while promoting a safe and healthy work environment.

Common Exclusions and Exceptions in Hazard Communication

The Hazard Communication Standard (HCS) includes certain exclusions and exceptions that employers should be aware of when it comes to labelling requirements and the scope of the standard. Here are some key points to consider:

1. Exemptions from Labeling Requirements

There are specific situations where certain chemicals may be exempted from labelling requirements. For example, if a chemical is considered a trade secret, it may be exempt from labelling as long as the appropriate procedures for maintaining confidentiality are followed. Additionally, chemicals used for research and development purposes in a laboratory may be exempt from immediate labelling if they meet certain criteria.

2. Known Exclusions from the Scope of the HCS

Employers should be aware of exclusions from the scope of the Hazard Communication Standard. For instance, the standard does not apply to articles, which are products that are formed to a specific shape or design during manufacture, have end-use functions dependent on that shape or design, and do not release hazardous chemicals under normal conditions of use.

Employers need to familiarize themselves with these exclusions and exceptions to ensure compliance with the Hazard Communication Standard and to accurately determine when labelling requirements apply.

By understanding these exclusions and exceptions, employers can effectively navigate the complexities of hazard communication and ensure that proper labelling practices are implemented where required.

Roles and Responsibilities: Hazard Classification and Communication Obligations

When it comes to hazard communication, the responsibility for accurate hazard classification falls on different parties involved in the supply chain. Manufacturers and importers play a crucial role in ensuring hazardous chemicals are properly classified, while downstream employers have the responsibility to effectively communicate these hazards to their workers. Let’s delve into the respective responsibilities of each party:

Manufacturers and Importers:

  1. Hazard Classification: Manufacturers and importers are responsible for assessing the hazards of the chemicals they produce or import. This involves determining the appropriate hazard classes/categories, such as flammable liquids, corrosive substances, or respiratory sensitisers. Accurate classification is essential for providing relevant information to downstream employers and ensuring appropriate protective measures are taken.
