New employees without HAZMAT training must work under supervision for how long?

New employees without HAZMAT training are required to work under supervision for 90 days to ensure they gain a comprehensive understanding of safety protocols and practices related to hazardous materials. This period is critical for allowing new hires to acclimate to the workplace environment, learn about the potential hazards they may encounter, and become familiar with the necessary safety procedures and equipment. The 90-day timeframe is a widely recognized guideline that provides adequate time for training and oversight, reducing the risk of accidents and ensuring compliance with safety regulations. This approach ultimately aims to create a safer working environment by ensuring that all employees handling hazardous materials have received the proper instruction and supervision before working independently.
