  2. Electrical injury - Wikipedia

    en.wikipedia.org/wiki/Electrical_injury

    This is known as the "let go threshold" and is a criterion for shock hazard in electrical regulations. The current may, if it is high enough, cause tissue damage or fibrillation which can cause cardiac arrest; more than 30 mA [12] of AC (rms, 60 Hz) or 300–500 mA of DC at high voltage can cause fibrillation.

  3. Electrical safety standards - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_standards

    The electrical safety develops with the technical progress. In 1989 OSHA [1] promulgated a much-needed regulation in the General Industry Regulations. Several standards are defined for control of hazardous energy, or lockout/tagout. In 1995 OSHA was successful in promulgation of regulations for utility. [2]

  4. Electrical equipment in hazardous areas - Wikipedia

    en.wikipedia.org/wiki/Electrical_equipment_in...

    Electrical equipment installed in such locations can provide an ignition source, due to electrical arcing, or high temperatures. Standards and regulations exist to identify such locations, classify the hazards, and design equipment for safe use in such locations.

  5. Physical hazard - Wikipedia

    en.wikipedia.org/wiki/Physical_hazard

    A physical hazard is an agent, ... overhead power lines and overloaded circuits are the common electrical hazards which are found on construction sites. ...

  6. Arc flash - Wikipedia

    en.wikipedia.org/wiki/Arc_flash

    Most 400 V and above electrical services have sufficient capacity to cause an arc flash hazard. [citation needed] Medium-voltage equipment (above 1000 V) is higher potential and therefore a higher risk for an arc flash hazard.

  7. High resistance connection - Wikipedia

    en.wikipedia.org/wiki/High_resistance_connection

    A high-resistance connection (HRC) is a hazard that results from loose or poor connections in traditional electrical accessories and switchgear which can cause heat to develop, capable of starting a fire. [1] Glowing connections occur when relatively high current exists in a relatively large resistance object. Heat comes from power dissipation ...

  8. NFPA 70E - Wikipedia

    en.wikipedia.org/wiki/NFPA_70E

    While the various OSHA, ASTM, IEEE and NEC standard provide guidelines for performance, NFPA 70E addresses practices and is widely considered as the de facto standard for Electrical Safety in the Workplace. Practices include: Staging a "safe work zone" with boundaries, barricades, signs and attendants.

  9. Lockout–tagout - Wikipedia

    en.wikipedia.org/wiki/Lockout–tagout

    The standard does not cover electrical hazards from work on, near, or with conductors or equipment in electric utilization (premise wiring) installations, which are outlined by 29 CFR Part 1910 Subpart S. [10] The specific lockout and tagout provisions for electrical shock and burn hazards can be found in 29 CFR Part 1910.333. Controlling ...
