How quickly must manufacturers and importers update an SDS after discovering new information about a chemical's hazard potential?

Manufacturers and importers are required to update a Safety Data Sheet (SDS) immediately upon discovering new information that affects the hazard classification of a chemical. This requirement is crucial for maintaining the safety of those handling or exposed to chemicals, as updated information can influence how these substances should be stored, handled, or disposed of. Prompt updates ensure that users have access to the most current safety information to mitigate risks associated with the chemical's use.

In this context, having an immediate response to new hazard information serves to protect workers, emergency responders, and consumers. Delays in updating the SDS could lead to unsafe conditions and increase the risk of accidents or adverse health effects, highlighting the importance of ensuring that safety information is always current and readily accessible.
