What is the required training frequency for employees on hazardous chemicals?

The correct answer highlights the requirement for training employees on hazardous chemicals whenever a new chemical is introduced into the workplace. This is crucial because the hazards associated with chemicals can vary widely, and new products may bring about different risks that employees need to be aware of to ensure their safety.

Training at the time of introducing new chemicals ensures that employees are informed about potential health effects, proper handling procedures, and emergency response actions specific to that chemical. This ongoing training approach helps maintain a safe work environment as it keeps all staff updated on the most current information regarding hazardous materials they may encounter in their work.

While annual training may help reinforce knowledge, it does not specifically address the immediate need to educate employees on new hazards as they arise. Similarly, training every two years or only during onboarding can lead to gaps in knowledge and awareness, putting employees at risk when they encounter unfamiliar chemicals. Thus, the requirement for training upon the introduction of new chemicals is designed to ensure continuous safety in the workplace.
