Arc flash events pose serious risks to personnel and equipment in electrical systems.


What is Arc Flash Containment?

Arc flash containment refers to the measures taken to mitigate the impact of an arc flash event, minimizing its extent and preventing catastrophic damage. Containment systems typically include barriers, enclosures, and personal protective equipment (PPE) to shield workers and equipment from the effects of an arc flash.

Why is Arc Flash Containment Important?

  1. Worker Safety: Containment systems help protect personnel from the thermal and blast hazards associated with arc flash incidents, reducing the risk of severe injuries or fatalities.
  2. Equipment Protection: By limiting the spread of arc flash energy, containment measures help prevent extensive damage to electrical equipment, minimizing downtime and repair costs.
  3. Compliance: Regulatory standards such as NFPA 70E require employers to implement arc flash mitigation strategies, including containment, to ensure a safe working environment.

Arc Flash Personal Protective Equipment (PPE):


Arc Flash Risk Level Assessment

  1. Risk Analysis: Conducting a thorough risk assessment to identify potential arc flash hazards, including voltage levels, equipment configurations, and work practices.
  2. Arc Flash Boundary: Determining the safe distance from an arc flash source where the incident energy is less than the threshold for second-degree burns (typically 1.2 cal/cm2).
  3. Personal Protective Equipment (PPE): Selecting appropriate PPE based on the calculated incident energy level and arc flash boundary, including arc-rated clothing, face shields, and gloves.

Containment Strategies:

  1. Enclosures: Using arc-resistant switchgear and panels designed to contain and redirect arc flash energy safely.
  2. Barriers: Installing physical barriers around high-risk equipment to prevent unauthorized access and limit exposure to arc flash hazards.
  3. Administrative Controls: Implementing safe work practices, including lockout/tagout procedures, to minimize the likelihood of arc flash incidents during maintenance and servicing.

By understanding arc flash containment measures and conducting comprehensive risk assessments, organizations can effectively mitigate the risks associated with arc flash events, ensuring the safety of personnel and the integrity of electrical systems.

It's an interesting topic, thanks for sharing. Arc flash study is to determine the incident energy available at specific device that an operator would be exposed to, while interacting with electrical equipment at facility. The result of Arc flash study will categorize the Hazard at specific equipment based on the incident energy, as well as identify the Arc flash protection boundary (the closest approach allowed before PPE must be worn). And inside the Arc flash protection boundaries a worker must be wearing proper clothing/ PPE. The PPE, main objective to wear is to restrict, or stop the burns of the body resulting from an arc flash event, to a survival level. The Arc flash Hazard study is done, in association with short circuit & protection device coordination study,as per IEEE Stnd 60909 and IEEE Stnd 242, respectively. Based on study findings, selection of PPE, electrical equipment of switchgear, substation shall be selected, rated, and warning levels A, B, shall be displayed "Arc Flash and Shock Hazard Present and Appreciate PPE are Required".
