• Handling and Storage: Recommendations for safe handling, storage, and transportation, ensuring the product is managed appropriately.
• Exposure Controls/Personal Protection: Details on personal protective equipment (PPE) required and engineering controls necessary to minimize worker exposure.
• Physical and Chemical Properties: A summary of the product's physical and chemical characteristics, providing crucial information for handling and storage.
• Stability and Reactivity: Information on the product's stability under various conditions, indicating potential hazards related to reactivity.
• Toxicological Information: An assessment of the health effects associated with exposure to the product, detailing potential acute and chronic risks.
• Ecological Information: An evaluation of the product's environmental impact, including its potential to harm aquatic life or contaminate soil.
• Disposal Considerations: Guidance on proper disposal methods, minimizing environmental risks and complying with regulations.
• Transport Information: Regulations concerning the transportation of the product, ensuring compliance with relevant transport codes.
• Regulatory Information: A summary of relevant regulations and legislation pertaining to the product's handling, use, and disposal.
• Other Information: Additional information or references relevant to the product's safety and handling.

SDSs are a crucial resource for workers, supervisors, and emergency responders. Easy access to SDSs is paramount, and they should be readily available in a centralized location.

1.3. Education and Training: Empowering the Workforce

Effective hazard communication is not complete without comprehensive worker education and training. This element ensures that workers understand the hazards associated with the products they handle and know how to protect themselves. Training should cover:

• Label Interpretation: Workers need to be able to understand and interpret WHMIS labels quickly and accurately.
• SDS Access and Understanding: Workers should know where to find SDSs and how to interpret the information contained within them.
• Safe Handling Procedures: Training should outline safe handling, use, storage, and disposal procedures for each controlled product.
• Emergency Procedures: Workers need to know what to do in case of accidents, spills, or exposure incidents.
• Personal Protective Equipment (PPE): Training should cover the proper use and selection of appropriate PPE for various tasks.

Regular refresher training is essential to reinforce learning and address any changes in procedures or regulations. A well-trained workforce is a safe workforce.

Part 2: Controlled Products – Identifying the Hazards

This part of WHMIS focuses on identifying and classifying products that are considered hazardous. These controlled products are subjected to specific labeling and SDS requirements. The classification system is based on several hazard classes, each representing a specific type of hazard. These classes can overlap, meaning a single product can fall under multiple hazard classes. Some key examples include:

• Class A: Compressed Gases: Gases stored under pressure, posing risks of explosion or asphyxiation.
• Class B: Flammable and Combustible Materials: Substances that can easily ignite and burn, posing fire hazards. This includes flammable liquids, flammable solids, and spontaneously combustible materials.
• Class C: Oxidizing Materials: Substances that can readily supply oxygen to fuel combustion, increasing the risk of fire.
• Class D: Poisonous and Infectious Materials: Substances that can cause serious health effects, ranging from mild irritation to death. This includes materials causing immediate toxic effects, as well as those causing chronic health problems.
• Class D1: Materials causing immediate and serious toxic effects: Highly toxic substances that can cause immediate and severe health problems with short exposure.
• Class D2: Materials causing other toxic effects: Substances that cause health problems with prolonged exposure.
• Class E: Corrosive Materials: Substances that can cause irreversible damage to living tissues or materials through chemical reactions.
• Class F: Dangerously Reactive Materials: Substances that can undergo violent chemical reactions under specific conditions, posing explosion or fire hazards.

Understanding the classification of controlled products is crucial for implementing appropriate safety measures. This part of WHMIS ensures consistent hazard identification across various industries, allowing for standardized safety protocols.
