Which agency is responsible for maintaining and enforcing the NFPA standards?

The National Fire Protection Association (NFPA) is the organization specifically tasked with developing and maintaining fire safety standards. The NFPA is a non-profit organization dedicated to minimizing the risks and effects of fire by offering codes, standards, research, and education designed to improve safety practices. Its standards are widely recognized and adopted in legislation and industry practices to ensure comprehensive safety measures are implemented in various sectors related to fire protection.

The other agencies listed have different roles: FEMA focuses on disaster preparedness and response, OSHA is concerned with workplace safety standards and regulations, and DHS deals with homeland security issues, including terrorism prevention and natural disaster response. None of them have the primary responsibility for the creation or enforcement of the NFPA standards, making the NFPA the correct choice for this question.
