    Protect workers from life-threatening hazards using first-time NFPA 350: Guide for Safe Confined Space Entry and Work.

    Every year, confined space incidents result in worker deaths, injuries, and serious illnesses. The danger is widespread because all facilities can have confined spaces -- from commercial buildings and hospitals to public works, utilities, and chemical/industrial facilities. By law in the United States, employers must comply with applicable regulations such as OSHA's 29 CFR 1910.146 and 29 CFR 1926 Subpart AA to ensure personnel safety. However, these regulations tell you 'what' to do, not 'how' to identify, evaluate, and control confined space hazards or conduct rescue response. To fill the information gap, NFPA introduces NFPA 350: Guide for Safe Confined Space Entry and Work.

    This all-new Guide is essential for anyone who enters confines spaces, along with facility managers, code officials, and safety personnel.

    NFPA 350 explains how to protect workers who enter into confined spaces for inspection or testing, or to perform associated work. Provisions address the full range of special hazards, including those present in water treatment, petrochemical, and agricultural facilities. It provides information to assist companies that need to comply with OSHA's Permit-Required Confined Spaces (29 CFR 1910.146) among other standards. In addition, NFPA 350 helps fire service and emergency services personnel develop and evaluate plans for confined space rescue in conjunction with NFPA 1670: Standard on Operations and Training for Technical Search and Rescue Incidents.

    Be prepared to recognize, evaluate, and control confined space entry hazards. Follow practices developed by experts for:

    • Identification of confined spaces
    • Evaluation of hazards
    • Atmospheric monitoring
    • Hazard elimination and control
    • Ventilation
    • Rescue and rescue planning
    • Confined space personnel duties, responsibilities, and competencies
    • Pre-entry evaluation forms and permits
    • Management of Change (MOC)
    • Prevention Through Design (PtD)

    A milestone for worker safety, NFPA 350 helps companies reduce the risks posed to workers in and around confined spaces, while it serves to protect facilities, equipment, non–confined space personnel, and the public from injuries associated with confined space incidents. (Softbound, 2016)
