National Fire Protection Assoc. has existed since early 1900's. The organization writes various engineering and technical standards on fire safety design of certain equipment, building features and firefighting equipment. NFPA standards are cited in many U.S. and Canadian fire and building codes....therefore it becomes part of law.
