How often must a supplier issue a new MSDS for controlled products?

A Material Safety Data Sheet (MSDS), now commonly referred to as Safety Data Sheet (SDS), must be updated and issued by suppliers at least every three years or sooner if new information becomes available about the chemical or product. This requirement ensures that workers and emergency responders have access to the most current information on hazards and safety precautions associated with the controlled products they may encounter. Regular updates also reflect new research, regulatory changes, or shifts in the understanding of a substance's health effects, which are crucial for maintaining workplace safety. This timeframe reinforces the importance of having up-to-date safety information readily available in environments where such materials are used, thereby promoting a culture of safety and compliance within workplaces handling hazardous materials.
