  • Description

    Build acetylene cylinder charging plants and install systems using the updated 2012 NFPA 51A.

    NFPA 51A: Standard for Acetylene Cylinder Charging Plants presents the most widely accepted safety requirements for the design, construction, and installation of acetylene cylinder charging plants, with requirements concerning:

    • Plant location
    • Acetylene generators
    • Gasholders
    • Compressors
    • Piping
    • Manifolds

    Fully coordinated with NFPA 55: Compressed Gases and Cryogenic Fluids Code, this 2012 edition of NFPA 51A includes new requirements related to building codes and standards and an all-new section on Mobile Acetylene Trailer Systems (MATS).

    Staying up-to-code helps you protect workers, the public, and facilities.

    The latest edition of NFPA 51A is a critical tool for architects, designers, installers, owners, AHJs, and anyone responsible for safety around acetylene cylinder charging operations. (Print, 19 pp., 2012)
