How often must hazard communication training be updated?

The requirement for hazard communication training to be updated whenever new hazardous materials are introduced is based on the principles of keeping employees informed about the hazards they may encounter in the workplace. When new substances are introduced, it's essential that workers understand the potential risks and proper handling procedures associated with these materials. This approach ensures that safety practices are current and relevant, minimizing the risk of accidents or exposure to harmful substances.

While annual refresher training can be beneficial, it is the introduction of new hazardous materials that specifically mandates the need for updated training to ensure that all employees understand the updated information and can respond appropriately to new risks. This ongoing process helps maintain a safe working environment and complies with regulations set forth by agencies like OSHA.
