Difference between OSHA and NIOSH

What’s the Difference? NIOSH vs OSHA


Two prominent agencies play pivotal roles in occupational health and safety—NIOSH and OSHA. While both organizations contribute to safeguarding workers, they have distinct roles and function.

This blog explains the key functions of both organizations and the main differences between NIOSH and OSHA when it comes to occupational safety and health.

NIOSH and OSHA play complementary yet distinct roles in occupational health and safety.

  • NIOSH focuses on research, recommendations, and education.
  • OSHA is responsible for setting and enforcing safety standards.
  • NIOSH is not a legal enforcement agency.
  • OSHA enforces regulations.
