What is IEC 60479-2:2021?

IEC 60479-2:2021 is a technical standard that pertains to the effects of electrical current on the human body. It provides guidelines and safety measures to prevent electrical shock and injury, as well as minimize potential harm caused by electric currents.

Understanding Electric Shock

Electric shock occurs when a person's body comes into contact with an electric current. The severity of the shock depends on various factors, including the magnitude of the current, the duration of exposure, and the path the current takes through the body.

Electric shock can cause a range of injuries, from mild discomfort to severe burns, heart arrhythmia, and even death. It is crucial to follow safety standards such as IEC 60479-2:2021 to mitigate these risks.

Key Concepts and Requirements

IEC 60479-2:2021 outlines several key concepts and requirements to ensure electrical safety:

Threshold of perception and pain: The standard defines the minimum levels of electric current required for a person to perceive or experience pain, which helps in determining safe limits for exposure.

Body impedance: It takes into account the resistance of the human body to electric current, which varies depending on factors like age, gender, and overall health.

Minimum clearance distances: The standard specifies the minimum distances that should be maintained between electrical equipment and conductive parts of the human body to prevent accidental contact and subsequent electric shock.

Protective measures: IEC 60479-2:2021 suggests various protective measures, including insulation, grounding, and the use of residual current devices (RCDs) to enhance safety in different electrical settings.

Adherence to IEC 60479-2:2021

Compliance with the guidelines outlined in IEC 60479-2:2021 is essential to prevent electrical accidents and ensure the well-being of individuals working with or around electrical systems. It is crucial for electrical engineers, designers, and manufacturers to have a thorough understanding of this standard and implement appropriate safety measures accordingly.

Furthermore, regular inspections, maintenance, and training on electrical safety should be conducted to ensure ongoing adherence to IEC 60479-2:2021, thus protecting both workers and end-users from the potential hazards posed by electric currents.
