NRTL, or Nationally Recognized Testing Laboratory, is a program of what organization?

The Nationally Recognized Testing Laboratory (NRTL) program is indeed associated with the Occupational Safety and Health Administration (OSHA). This program was established to ensure that products meet specific safety standards for use in occupational settings. NRTLs are responsible for testing and certifying that various electrical and electronic products, as well as other equipment, comply with the relevant safety requirements and standards set forth by OSHA.

OSHA, being a part of the U.S. Department of Labor, oversees workplace safety and health regulations, which encompasses the proper functioning and safety of fire alarm systems and other critical safety equipment. The recognition of these laboratories by OSHA helps facilitate a safer working environment by ensuring that equipment is reliable and has been rigorously tested for safety.

The other organizations mentioned do not have direct involvement with the NRTL program. For instance, NIOSH focuses on research and recommendations for the prevention of work-related injury and illness, while FEMA is primarily concerned with emergency management and disaster response. The EPA, on the other hand, is involved with environmental protection rather than workplace safety standards. Thus, the alignment of the NRTL program with OSHA's mission solidifies why this answer is correct.
