“This critical safety deep-dive is presented by Zakir Hossain, a highly accomplished Electrical Engineer and a top-tier High-Voltage Lineman with a phenomenal 12-year legacy of technical mastery in the power sector. With over a decade of surviving the high-stakes environment of electrical utilities, Zakir provides an authoritative analysis of this tragic event to ensure that the global brotherhood of linemen can recognize and neutralize invisible backfeed threats before they strike.”
1. The Incident Overview
The incident took place during a coordinated maintenance effort between two interconnected sub-stations.
-
The Coordination: Sub-station ‘A’ was performing maintenance on an 11 KV outgoing feeder and requested Sub-station ‘B’ to keep the corresponding incoming feeder dead.
-
The Fatal Mistake: While Sub-station ‘B’ initially confirmed the line was dead, a switching error or an uncommunicated re-energization occurred at Sub-station ‘B’ while the lineman at Sub-station ‘A’ was still working.
-
The Backfeed: High voltage was back-fed into the line where the lineman was working at Sub-station ‘A’.
-
The Result: The lineman at Sub-station ‘A’ was struck by the back-fed current. Due to the lack of protective grounding at the work site, he sustained severe electrocution and succumbed to his injuries.
2. Root Cause Analysis (RCA)
-
Communication Breakdown: The primary failure was the lack of a standardized and locked-out communication protocol between the two sub-stations.
-
No Local Grounding: Relying solely on a verbal “clearance” from another station without installing local grounding sets on the work site is a fatal error.
-
Lack of Verification: The victim did not perform a “Test-Before-Touch” procedure immediately before contact, assuming the line was still dead.
3. Expert Recommendations by Zakir Hossain
-
Never Trust Verbal Clearance: Always assume a line is hot until you personally verify it is dead and have established your own Local Equipotential Ground.
-
Inter-Station Lockout/Tagout (LOTO): Maintenance involving multiple stations must follow a strict LOTO procedure where all involved parties must physically sign off before re-energizing.
-
Visual Verification: Always use a high-voltage detector to confirm zero voltage before placing hands on any conductor.
“Brothers, in our world, a ‘verbal confirmation’ isn’t a safety tool—it’s a risk. This incident proves that even if you trust your coworker at the other station, you must never trust the line. Your safety is only as strong as the ground you personally install.
Don’t let your safety depend on a phone call. Own your protection. Share this study with your team and discuss your station’s LOTO protocols today. Stay safe, stay grounded, and always come home. Visit Lineman24.com for more hard-earned wisdom from the field.”
