IEC TR 62713:2013

Overview

IEC TR 62713:2013, titled Safety procedures for reduction of risk outside a structure, is a technical report published by the International Electrotechnical Commission (IEC). It provides essential guidance to non-specialists regarding lightning safety during outdoor activities. This standard introduces lightning hazards, explains the risks of lightning strikes, and outlines practical steps to minimize injuries and damages when caught outside during thunderstorms.

The report recognizes that lightning cannot be entirely avoided; however, adherence to straightforward safety procedures can significantly reduce the adverse effects of lightning incidents. It serves an informative purpose, focusing on safety precautions for people outdoors, including immediate first aid measures for lightning injuries.

Key Topics

IEC TR 62713 covers a range of important topics that help users understand and mitigate lightning risks outdoors:

• Lightning Basics and Hazards: Understanding the powerful forces involved in lightning, including extremely high voltages and currents up to 200 kA that can cause explosions, fires, and structural damage.
• Modes of Lightning Injury:
  • Direct strikes: Lightning hitting the body directly.
  • Side flashes: Lightning jumping from a nearby object to a person.
  • Touch and step voltages: Electrical potentials that cause current flows through a human body on or near the ground.
• Effects on Human Health: Details on possible injuries such as cardiac arrest, respiratory issues, neurological effects, burns, and other trauma caused by lightning.
• Safety Measures and Behavior During Thunderstorms:
  • Detecting lightning risk using visual and acoustic clues.
  • Identifying safe locations, including lightning-protected structures and vehicles acting as Faraday cages.
  • Recommended actions when caught outdoors - avoiding high points, isolated trees, and open water.
  • Guidelines for special situations such as camping, mountain activities, water sports, outdoor festivals, and playing sports.
• First Aid for Lightning Victims: Essential steps for assisting injured persons, including cardiopulmonary resuscitation (CPR) and handling respiratory and cardiac arrest.

Applications

This IEC technical report is highly valuable for public safety officers, outdoor event coordinators, educators, campers, sports organizations, and individual outdoor enthusiasts. Practical applications include:

• Enhancing public awareness of lightning hazards and correct responses to thunderstorms.
• Training personnel on immediate safety procedures to follow during lightning storms.
• Providing first responders and lay rescuers with guidance on how to assist lightning strike victims effectively.
• Incorporating lightning safety education into outdoor recreational programs, workplaces, and schools.
• Supporting emergency preparedness plans for outdoor events and activities by incorporating risk reduction strategies.

Related Standards

While IEC TR 62713 focuses on safety procedures for individuals outside structures during thunderstorms, it complements other IEC standards related to lightning protection, such as:

• IEC 62305: The comprehensive standard series covering lightning protection system design for buildings and structures, including risk assessment and protective measures.
• IEC 61024: Protection of structures against lightning, focusing on the technical design of lightning protection systems.
• IEC 61400 Series: Standards addressing lightning protection of wind turbines and related electrical systems.

These standards collectively ensure holistic lightning risk management - from structural protection to personal safety outdoors.
