NFPA 501-2017 PDF Download

The NFPA 501-2017 standard provides industry-accepted practices to maximize safety for manufactured housing. This standard covers all aspects related to the equipment and installations used in the design, construction, transportation, fire safety, plumbing, heat-producing, and electrical systems of manufactured homes. It aims to ensure comprehensive safety measures are in place for occupants of manufactured housing, including provisions for safe rooms in areas prone to natural disasters and requirements for water mist sprinkler systems.

The 2017 edition of NFPA 501 includes several updates to improve safety. It introduces a new requirement for measuring total smoke released, providing an optional measurement where smoke limitations are desired. The test for cellulose loose-fill insulation now specifies CAN/ULC S102.2 instead of ASTM E84 or UL 723, as it has been found that the latter methods are not appropriate for testing this type of insulation. Redundant requirements have been removed to align with NFPA 275, and references and extracts have been appropriately updated.

Manufacturers, installers, and authorities having jurisdiction (AHJs) can rely on the NFPA 501-2017 edition to stay up-to-date with the latest requirements and ensure the continued safety of manufactured housing. This standard is a crucial resource for maintaining safety in the industry.
