Lightning and sudden downpours that primarily occur during summer months are unpredictable weather risks that can threaten workplace safety within minutes. To minimize risks such as lightning strike accidents during outdoor work and work interruptions due to sudden heavy rainfall, it is essential to "quickly detect sudden changes, make judgments, and take action."

What are Lightning & Sudden Downpours? — Risks Approaching in Minutes

Lightning strikes are caused by developed storm clouds and can cause significant damage to human bodies, equipment, and infrastructure. Sudden downpours bring extremely heavy rain in localized areas over short periods, creating multiple overlapping risks including flooding, water damage, and strong winds. When thunder is heard, you may already be within the danger zone. Early response is particularly required at the following types of sites: ・Outdoor construction sites and high-altitude work sites ・Factories, large commercial facilities, and leisure facilities ・Stadium outdoor event venues ・Agricultural/fishing work in natural environments ・Transportation infrastructure requiring outdoor operations such as airports, ports, and railways

Lightning Protection for Workers — Immediate Response and Sign Detection

To minimize lightning damage, accurately detecting early signs and taking swift action is most important. Lightning cloud approach doesn't happen suddenly - it can be detected in advance through cumulonimbus development and sudden cold wind gusts. Monitoring these signs without missing them and detecting danger early is the first step in damage prevention.

After detecting signs, immediate appropriate action is essential. Swift decision-making and execution are required depending on the situation, such as stopping outdoor work and preparing for power outages.

However, relying solely on individual experience and judgment can lead to inconsistent responses and dangerous gaps in important measures. Therefore, establishing lightning countermeasure manuals within companies is extremely important. ● Weather condition judgment criteria ● Action procedures and evacuation rules ● Clear command structure and reporting systems ● Work resumption and recovery procedures By building a system where all employees can take unified responses, reliable lightning countermeasures can be achieved organization-wide.

Effective for Safety Management & BCP Measures

While lightning is one of the unpredictable natural disasters, damage can be avoided with proper information and preparation.

In recent years, from a BCP (Business Continuity Planning) perspective, response capabilities to sudden weather risks have become increasingly important.

"Visualizing" lightning risks not only protects employee lives but also leads to stable business operations and maintaining social credibility.
