Analyze the Right to Know standards

Under occupational safety regulations (such as OSHA's Hazard Communication Standard), the "Right to Know" ensures employees are fully informed about workplace hazards, chemical risks, and protective measures.

Evaluate the given options

• "Any hazardous substances present in the workplace" is a core requirement of hazard communication.
• "The hazards associated with the chemicals they use" is essential for safe handling.
• "How to use PPE to protect themselves" is required to ensure employees can protect themselves from identified hazards.

Determine the correct choice

Since all three individual options represent fundamental employee rights under safety standards, the correct choice is "All of the above".
