Introduction
A lightning risk assessment and protection study for an automobile ancillary plant in Bhiwadi, Rajasthan identified an unacceptable lightning risk level (per IEC 62305-2) and designed a compliant Lightning Protection System (LPS) reducing risk by 82%, protecting ₹45 crore of production equipment and 380 workers.
IEC 62305-2 (implemented in India as IS/IEC 62305) defines acceptable risk thresholds for industrial facilities; plants handling flammable materials (cutting fluids, paint booths) or housing sensitive electronic equipment are classified as Risk Category III, requiring formal risk assessment before LPS installation. The National Crime Records Bureau (NCRB) data shows lightning strikes caused 2,876 deaths in India in 2022 — more than floods and cyclones combined — with Rajasthan recording 312 fatalities, the third highest nationally.
An automobile ancillary plant in Bhiwadi (Rajasthan Industrial Area) with 18,000 sq.ft of sheet metal workshop, a paint booth, and an electronic assembly section had no surge protection devices (SPDs) on incoming power supply, an inadequate 1990s-era rod-type lightning conductor with high earth resistance (>10 Ω vs. IS 3043 requirement of <1 Ω), and a paint spray booth directly below a zone of highest lightning exposure. Following the LPS upgrade (cost: ₹3.8 lakh), the plant achieved IEC 62305 Risk Category compliance and qualified for a 12% insurance premium reduction worth ₹1.9 lakh annually.
Bhiwadi’s location in the Rajasthan-Haryana border region experiences 20–35 thunderstorm days annually (Isokeraunic Level 30–35); combined with the dense concentration of metal fabrication units (high radar cross-section), automotive paint booths (flammable Zone 1 environments), and precision electronic assembly, the industrial area faces above-average lightning risk compared to the regional mean.
“IEC 62305 studies show that industrial facilities with flammable material storage (paint, solvents, cutting fluids) face a lightning-initiated fire risk 8–12× higher than ordinary buildings, with average fire damages of ₹35–120 crore per incident in the automotive sector.”
