Construction sites are among the most lightning-vulnerable workplaces. Tall cranes, metal scaffolding, open terrain, and workers operating heavy equipment outdoors create significant risk during electrical storms. Boltek lightning detection systems help site managers meet safety obligations and protect workers by providing reliable, automated storm warnings.

Crane and Heavy Equipment Safety
Tower cranes and boom equipment act as lightning attractors and must be shut down before storms arrive. Boltek’s ERL-10 detection packages provide automatic alerts that give crane operators and riggers time to lower loads, secure equipment, and evacuate elevated positions before dangerous conditions develop.
Outdoor Worker Protection
Construction workers on open sites, rooftops, and scaffolding are directly exposed to lightning risk. Boltek systems trigger outdoor LED warning signs and high-powered horn speakers that can be heard across noisy job sites, ensuring every worker receives the warning to seek shelter in time.
Regulatory Compliance
Occupational safety regulations require construction sites to have lightning safety plans and warning systems in place. Boltek’s detection systems provide documented, automated monitoring that supports compliance with OSHA guidelines and provincial/state workplace safety requirements. The ERL-10 KIT2 Dual Sensor Lightning Detection System’s included LD-250 Lightning Detector tracks storms from 300 miles away, giving site supervisors ample time to execute safety procedures.
