Which organization is primarily focused on codes and standards for fire safety, including hazardous materials?

The correct answer is the National Fire Protection Association (NFPA), which is primarily focused on codes and standards for fire safety, including hazardous materials. The NFPA develops and publishes various codes and standards that address fire prevention, response, training, and safety practices, encompassing a wide range of topics related to hazardous materials. Among its various codes, NFPA 472 lays out the standards for the response to hazardous materials incidents, providing a framework for training and operational procedures for emergency responders.

The other organizations mentioned have distinct purposes that are different from the focus of the NFPA. The National Safety Council is committed to promoting safety training and education for various industries but does not specifically focus on fire safety codes and standards. The National Institute for Occupational Safety and Health primarily focuses on worker safety and health across various industries, not specifically on fire safety codes. The Occupational Safety and Health Administration plays a role in enforcing workplace safety regulations, but its focus is broader than just fire safety and includes multiple aspects of occupational health and safety.
