Which of the following organizations has NOT developed an Occupational Health and Safety Management System Standard?

The International Labor Organization (ILO) has not developed a specific Occupational Health and Safety Management System Standard in the same way as the other organizations listed. The ILO focuses on promoting social justice and fair labor practices, including occupational safety and health, but it does not create management system standards.

In contrast, the International Organization for Standardization (ISO) has developed ISO 45001, which provides a framework for managing occupational health and safety risks. The American National Standards Institute (ANSI) also has standards related to occupational safety, including those developed in partnership with other organizations. The National Safety Council (NSC) is involved in safety-related training and initiatives, but it also supports standards for workplace safety.

Thus, while the other organizations have concrete standards that provide structured approaches to managing occupational health and safety, the ILO takes a broader approach focused more on advocacy and policy rather than specific management system standards.
