NFPA (Fire) 501 Historical

The 2017 edition of NFPA 501 helps you maximize safety for manufactured housing with updates to the industry accepted practices. 

NFPA 501: Standard on Manufactured Housing covers all the equipment and installations used in the design, construction, transportation, fire safety, plumbing, heat-producing, and electrical systems of manufactured homes. 

The Standard covers virtually every aspect of safety. To be more comprehensive, the previous edition added requirements on safe rooms to provide a safe area for occupants of manufactured housing in areas prone to hurricanes, tornados, and other natural disasters. Requirements on water mist sprinkler systems reference the 2016 edition of NFPA 13D: Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes. 

Update to the 2017 edition for the latest safeguards.

• A new requirement for total smoke released provides an optional measurement where smoke limitations are desired.
• The test for cellulose loose-fill insulation specifies CAN/ULC S102.2 because it has been shown that cellulose loose-fill insulation cannot be tested appropriately using ASTM E84 or UL 723.
• Requirements in 5.8.2.3.1 and 5.8.2.3.2 have been removed to avoid redundancy with NFPA 275.
• NFPA 750 was removed as a reference because it is not an approved automatic sprinkler system and has not been proved to be equivalent to any of the NFPA 13
• References and extracts are appropriately updated.

Manufacturers, installers, and AHJs can depend on the 2017 edition of NFPA 501 for up-to-date requirements that help ensure the continued safety of manufactured housing.
