2.2 US Standards ANSI, NFPA, UL (National Consensus Standards)

In addition to the OSHA standards, the OSHA authority is authorized to monitor and enforce compliance with National Consensus Standards. These are standards, occupational health and safety regulations or modifications of such, which

  • have been adopted and published by a nationally recognized standards-setting organization (e.g. ANSI, UL),

  • are recognized by the Secretary of Labor as standards,

  • deal as international standards (IEC, ISO) with topics or specialist areas that are not covered by a US standard.

U.S. National Consensus Standards are therefore standards that apply as supplementary to the OSHA standards. The following are some of the bodies that provide such standards:

  • American National Standards Institute (ANSI)
    www.ansi.org

  • European Committee for Standardization (CEN)
    www.cen.eu

  • European Committee for Electrotechnical Standardization (CENELEC)
    www.cenelec.org

  • International Electrotechnical Commission (IEC)
    www.iec.ch

  • International Standardization Organization (ISO)
    www.iso.ch

  • National Fire Protection Agency (NFPA)
    www.nfpa.org
