The 2009 NFPA 51B Standard for Fire Prevention During Welding, Cutting, and Other Hot Work provides vital requirements for anyone who manages, supervises, or performs hot work --including outside contractors and property managers. Provisions apply to welding and allied processes, heat treating, grinding, thawing pipe, powder-driven fasteners, hot riveting, and similar applications producing a spark, flame, or heat.

Updated to avoid the latest recognized hazards, NFPA 51B advances safety on the job with

·    A new requirement for listed and/or approved welding blankets, pads, and curtains, included definitions of the terms

·    Updated permit information

·    Clarification of the "35-foot" rule

·    Alternative methods to hot work

·    Requirements for hot work contractor site-specific hazard awareness

·    New requirements for PPE

To stay up-to-code, reduce fire risks, and ensure the safety of employees and facilities, rely on NFPA 51B.
