What is a critical aspect of training for employees who handle chemicals?

Understanding the timing of training for employees who handle chemicals is crucial for maintaining safety in the workplace. The correct choice emphasizes that training must occur before any handling of hazardous materials. This proactive approach ensures that employees are equipped with the necessary knowledge and skills to recognize hazards, understand safety protocols, and respond appropriately in emergency situations.

By receiving training beforehand, employees learn about the proper use of personal protective equipment, how to read Safety Data Sheets (SDS), and the proper handling and disposal of chemicals. This foundational knowledge is essential for preventing accidents and minimizing exposure to hazardous substances, ultimately fostering a safer work environment.

On the other hand, options suggesting that training should be optional or only after exposure incidents do not adequately prioritize safety. Training must be an integral part of the onboarding process for anyone who will be working with chemicals, rather than something that is only addressed reactively or considered unnecessary.
