What does the right to know law require employers to do?

The right to know law primarily focuses on ensuring that employees are informed about the hazardous substances they may encounter in their workplace. By requiring employers to post notices where toxic substances are present, the law aims to create a safer working environment by promoting awareness and understanding of potential health risks. This signage provides crucial information about the chemicals in use, allowing employees to recognize and respond appropriately to possible hazards.

The other options, while relevant to workplace safety and employee rights, do not directly align with the specific mandates of the right to know law. Access to personal files pertains to privacy rights, training on intoxicating substances falls under different regulations related to substance abuse, and distributing safety equipment deals more with personal protective equipment requirements rather than the notification aspect central to the right to know provisions.
