Which sections of the Material Safety Data Sheet are not enforced by OSHA?

The correct answer is based on the understanding of the structure and requirements of a Material Safety Data Sheet (MSDS), now more commonly referred to as a Safety Data Sheet (SDS). According to the Occupational Safety and Health Administration (OSHA), certain sections of the SDS are mandated to contain specific information about hazardous substances, primarily sections 1 through 11.

Sections 12 through 16 of the SDS include more general information, which while useful, are not specifically enforced by OSHA regulations. These sections typically cover ecological information, disposal considerations, transport information, regulatory information, and other miscellaneous information. As such, although they may provide valuable insights, they do not hold the same regulatory consequences and compliance requirements as the earlier sections.

This distinction highlights that while the initial sections are critical for evaluating hazards and ensuring safety in the workplace, the latter sections serve additional informational purposes and might not directly impact compliance under OSHA's hazardous communication standards.
