Weekly digest #72: jobsite safety incidents

What the latest jobsite data is telling us

OSHA's 2025 construction fatality numbers landed earlier this month, and electrical contact remains the fourth leading cause of death on jobsites, behind falls, struck-by, and caught-between. Of the electrical fatalities, roughly 60% involved contact with overhead power lines, and another 25% involved live parts inside panels or equipment that should have been locked out.

The pattern is consistent year over year. Most incidents are not caused by exotic failures. They come from skipped steps on jobs the electrician had done hundreds of times before.

The takeaway is not that electricians need more training on esoteric hazards. It is that the basics, LOTO, PPE, approach boundaries, working space, are the same items showing up on the autopsy reports.

Lockout/tagout: the step that keeps getting skipped

NFPA 70E Article 120 requires an electrically safe work condition before working on or near exposed energized parts. That means disconnect, LOTO, test for absence of voltage with a verified meter, then test the meter again on a known source. No shortcuts.

Field reports from the past quarter show the most common LOTO failures are:

• Testing the meter only after the verification, not before and after
• Locking out the wrong disconnect on multi-source equipment (missed backfeed from a UPS, generator, or PV)
• Relying on a control circuit stop instead of the actual supply disconnect
• Removing a lock for a "quick check" without re-verifying when work resumes

If the equipment can be fed from more than one source, every source gets a lock. PV systems under NEC 690.13 and interconnected sources under 705.12 will happily backfeed a disconnect you thought was dead.

Before you touch anything, ask yourself: if this conductor were live right now, would I still be standing here comfortably? If the answer is no, you have not actually verified it is dead.

GFCI and the receptacles people die on

NEC 210.8 has expanded significantly in the last three cycles, and the incident data shows why. Non-GFCI-protected 120V receptacles in damp or wet locations continue to be a primary shock fatality source for both trades and homeowners.

For 2023 and 2026 code jurisdictions, confirm GFCI protection at:

1. All 125V through 250V receptacles in dwelling bathrooms, kitchens, garages, outdoors, basements, laundry, and within 6 feet of any sink, tub, or shower (210.8(A))
2. Commercial kitchens, rooftops, outdoor areas, and indoor wet locations (210.8(B))
3. Crawl spaces, unfinished accessory buildings, and boathouses (210.8(A)(4) and related)
4. Outlets supplying specific appliances like dishwashers and ranges per 210.8(D)

On service calls, if you find a tripped GFCI behind a refrigerator or sump pump, do not just reset it and walk away. That device tripped for a reason, and the 2023 NEC tightened the self-test requirements precisely because nuisance-tripping GFCIs were being bypassed in the field.

Working space: not a suggestion

NEC 110.26 working space violations are showing up in both electrocution and arc flash incident reports. Crews get hurt because they cannot step back from an arcing panel when there is a water heater or storage rack in the clearance zone.

The minimums have not changed in this cycle. For 0 to 150V to ground, Condition 1, you need 3 feet of depth, 30 inches of width or the width of the equipment (whichever is greater), and 6.5 feet of headroom. Higher voltages and conditions with grounded or exposed live parts on the opposite side require more.

If you show up to a panel and the working space is blocked, document it, photograph it, and do not work live in that space. Arc flash energy does not care that the homeowner put their Christmas decorations there six months ago.

PPE: arc rating matters more than you think

NFPA 70E requires arc-rated clothing matched to the incident energy at the working distance. A Category 2 rating (8 cal/cm²) is the minimum for most panelboard work below 240V, and you need a face shield or arc flash hood, not just safety glasses, any time you are inside the restricted approach boundary on energized equipment.

Field-observed failures this quarter:

• Synthetic base layers under arc-rated outerwear (the base layer melts)
• Untucked arc-rated shirts, leaving a gap at the waist
• Voltage-rated gloves past their 6-month retest date
• Class 00 gloves being used on circuits above 500V

Your PPE is rated for the worst day you might have on that circuit, not the average day. If your incident energy calc says Category 3 and you are wearing Category 2 because it is hot out, you are gambling with the numbers.

What to carry into next week

None of this is new information. The electricians getting hurt this year knew the code, knew the PPE rules, and knew the LOTO sequence. What failed was the decision to skip a step on a job that felt routine.

Build the habit of treating every energized conductor as a live one until your meter says otherwise, twice. Verify your sources, verify your boundaries, and verify your PPE matches the work. The code articles above are not bureaucratic overhead, they are the distilled record of what has already killed people in this trade.
