Lightning is not only a weather event — it is a serious electrical hazard that can strike people, structures, power systems and equipment. A safe worksite begins with recognizing the warning signs and taking action before conditions become dangerous.
Imagine a fabrication yard during an active thunderstorm. Dark clouds are building, thunder is becoming frequent, and lightning is visible in the surrounding area. Workers are still performing outdoor activities near scaffolding, lifting equipment, electrical installations, steel structures and open areas.
Do not wait for lightning to strike your work area. Once thunder is heard, workers should move to an appropriate safe shelter and remain there until the storm has passed and the responsible site team confirms it is safe to resume work.
Take shelter inside a substantial building or an enclosed, hard-top vehicle.
Maintain distance from power lines, electrical equipment, substations, towers and other conductive structures.
Suspend activities involving cranes, scaffolding, work at height, steel erection, open-area maintenance and other exposed operations when lightning conditions create a hazard.
Never shelter under isolated trees, temporary structures or near utility poles.
Avoid ponds, rivers, drainage channels, pools and other water bodies during thunderstorms.
Listen to the HSE team, emergency coordinator and authorized weather-monitoring instructions.
STOP → KEEP AWAY → WARN OTHERS → REPORT IMMEDIATELY
A few minutes of lost production is nothing compared with the potential consequences of a lightning-related incident.
