What is IEC 60479?

IEC 60479, also known as International Electrotechnical Commission Standard 60479, is a globally recognized technical standard that focuses on the effects of electric current on the human body. It provides guidelines to assess and mitigate the risks associated with electrical installations, aiming to ensure the safety of people working in or around electrical systems.

Importance of IEC 60479

IEC 60479 plays a crucial role in promoting electrical safety in various industries such as construction, manufacturing, and power generation. By strictly adhering to this standard, organizations can prevent electrical accidents, reduce injuries, and ultimately save lives.

The standard outlines several key principles and concepts related to the effects of electric shock on the human body:

1. Threshold of Perception: IEC 60479 defines the minimum level of electric current that an average person can perceive under specific conditions. Understanding this threshold helps determine the minimum safety measures required for electrical systems.

2. Ventricular Fibrillation: The standard emphasizes the risk of ventricular fibrillation, a potentially fatal condition caused by excessive electric shocks. It provides guidance on measures to minimize the likelihood of ventricular fibrillation, including appropriate grounding and fault protection devices.

3. Effects of Current Magnitude and Duration: IEC 60479 highlights the relationship between current magnitude, duration of exposure, and the severity of its effects. By assessing the potential hazards associated with different current levels, organizations can implement suitable safety precautions.

Application of IEC 60479

IEC 60479 is widely applied in various stages of an electrical system's lifecycle:

1. Design and Installation: During the design phase, this standard helps engineers determine adequate safety measures, such as proper insulation, grounding, and considering human thresholds. Installations are carried out ensuring compliance with the guidelines laid out in IEC 60479.

2. Operations and Maintenance: Organizations need to conduct regular inspections and maintenance checks to ensure electrical systems are functioning safely. Following IEC 60479 helps identify potential risks and take appropriate actions to minimize them.

3. Training and Awareness: Educating personnel about the hazards associated with electric currents is a critical aspect of electrical safety. By incorporating the principles outlined in IEC 60479 into training programs, organizations can enhance awareness and promote safe working practices.

Conclusion

IEC 60479 serves as a vital reference for promoting electrical safety across industries. Adhering to its guidelines ensures that electrical installations are designed, operated, and maintained in a manner that prioritizes the well-being of individuals working with or near electrical systems. By understanding the effects of electric current on the human body and implementing appropriate preventive measures, organizations can significantly reduce the risk of electrical accidents and create a safer working environment.
