They Cut Into Eight Years of Gas

Eighty-three years ago tonight, eleven coal miners in a little Boone County town died because a machine cut through one wall into a room nobody had looked at in eight years. The gas was always there. The system just never went to check. That’s the whole story, and it’s still the story on half the jobs I walk today.

It was a Saturday, about 7:00 p.m. Forty men were working the American Rolling Mill Company’s Nellis No. 3 mine, roughly 16 miles north of Madison. A cutting machine in room 38 was driving coal off the 24 north entry — routine work, a crew doing what they’d done a thousand times.

Then the machine cut through into 25 south.

25 south was an entry that had been abandoned around 1935 — eight years earlier. It had not been ventilated. It had not been inspected. Nobody had put air or eyes on it in close to a decade. Behind that wall of coal sat a body of methane that had been quietly building the whole time, with nowhere to go. The moment the cut broke through, that gas rolled into the working section and found an ignition source — most likely an arc off the electric locomotive’s cable nip, possibly the open-type cutting machine itself.

The U.S. Bureau of Mines final report lays it out flat: nine men killed outright by violence, burns, and afterdamp — the carbon-monoxide-laden air an explosion leaves behind. Two more, including 23-year-old Lawrence Vincent, made it out alive and died in the hospital hours later. Twenty-nine escaped on their own; some still took a dose of carbon monoxide doing it. The blast was so violent it tore the clothing off the men it caught. By morning, 350 family and friends had gathered at the mine mouth and stood vigil until the last body came up.

Their names are cut in stone on a monument in Nellis to this day: William C. Barker, Julias Domokos, Lester Gunnoe, William H. Gunnoe, O’Dell Linville, Onal O. Miller, John Setliff, Steve Turkovitch, Lawrence J. Vincent, John Williams, and William O. Workman.

This one wrote three lines of the rulebook, all of them in blood. First: ventilate and examine every worked-out and abandoned area. The killer here wasn’t the cut — it was eight years of nobody checking a space the mine had written off. Today that’s 30 CFR 75.360 and 75.364 (pre-shift and weekly examinations, including of worked-out areas) and 30 CFR 75.323 (what you do the second methane climbs). “Abandoned” is not the same as “safe.” It just means the hazard stopped being watched.

Second: permissible — explosion-proof — electric equipment in gassy ground. An arc off a locomotive or an open cutting head lit the gas. That exact failure is why 30 CFR Part 75, Subpart F requires permissible equipment where methane can collect. An arc you’d never notice in fresh air is a detonator in a gas layer.

Third: rock dust so a flame can’t run. At Nellis the explosion stayed local, but by luck, because the entries happened to be wet, not because the dust was inerted. Don’t bet men’s lives on wet weather. 30 CFR 75.402 through 75.403 exists so coal dust can’t carry a flame front down the mains.

And here’s the part that should sit with every one of us: in 1943, a federal inspector could have walked that mine, seen the unventilated abandoned entry and the non-permissible locomotive, written every bit of it down — and had almost no power to make anyone fix it. Real enforcement didn’t arrive until the 1969 Coal Act and, later, MSHA under the 1977 Mine Act. Eleven men at Nellis are part of the body count that bought those laws. The rule you follow today exists because somebody already paid for the lesson.

Translate it to the floor: you don’t have a 1935 entry. But you’ve got the capped line nobody’s opened in years, the “dead” tank you walk past, the abandoned pit on the back of the property, the room marked do-not-enter that everyone has stopped thinking about. Methane, H2S, a nitrogen blanket, simple oxygen deficiency — bad air doesn’t need a coal seam. It just needs a space no one is checking and a day you cut into it blind.

Most incidents are Environmental, Health, and Safety all at once — the same failure wearing three coats. The safety failure is the one above: gas in an unmonitored space, a non-permissible ignition source, no barrier to stop the flame. Environmentally, it was contained underground — the report records no offsite release that night — but the thread is the same molecule: the methane that killed these men is a greenhouse gas roughly 80 times more potent than CO2 over 20 years, and coal-mine methane is a leak EPA now runs a whole outreach program to capture. The abandoned workings that fed this blast are the same kind that still bleed acid mine drainage, low-pH and metal-laden, into Appalachian streams under Clean Water Act / NPDES permits and SMCRA reclamation today. On health: the acute killer was afterdamp — carbon monoxide, the gas that quietly takes most mine-explosion victims and clipped even the survivors — and the chronic one is the dust, coal workers’ pneumoconiosis, black lung, the disease NIOSH still tracks and the 1969 Coal Act finally wrote dust limits and benefits for. One line ties it together: the same methane that burns a crew heats the planet, and the same coal dust that can carry the flame fills the lungs of the men who walk out. Kill the hazard and you’ve answered all three.

The silica rule is paused. The disease is not. MSHA’s 2024 respirable crystalline silica rule — the one that halves the exposure limit to 50 micrograms per cubic meter — is still frozen by the courts. The Eighth Circuit stayed compliance in 2025, and in an April 2026 Federal Register notice MSHA indefinitely delayed the conforming-amendment effective dates for metal and nonmetal mines, with coal enforcement delayed too (Program Information Bulletin P26-01). So what for safety leaders: a court can stay a deadline; it can’t stay silicosis. Lungs scar on their own schedule. If you run dust — mining, cutting, grinding, blasting, frac sand — keep your sampling, controls, and respiratory program running as if the 50 goes live tomorrow, because for the worker breathing it, it already did.

Fall protection tops OSHA’s list again, and the totals dropped. OSHA’s preliminary FY2026 Top 10 (federal citations, Oct 2025 through Aug 2026) has fall protection, 1926.501, at No. 1 with 4,041 citations — more than double anything else — for yet another year running. Hazard communication (1,961) and lockout/tagout (1,863) follow. Total citations across the Top 10 fell from about 23,500 to 17,700. So what for safety leaders: don’t read that drop as “sites got safer.” Fewer citations usually means fewer inspectors knocking, not fewer hazards. The list hasn’t changed in a decade — falls, chemicals, energy — because the ways we hurt people haven’t changed. Work the fundamentals; nobody’s grading on a curve out there.

A two-man crew went to pull a pump out of a below-grade wet well. The four-gas monitor had been bump-tested that morning and was clipped to the first guy’s belt — everything by the book. He started down the ladder. Partway in, the monitor alarmed: low oxygen. He kept going.

Here’s why, and it’s not what you think. That monitor’s low-battery chirp had been going off all week, and the crew had learned to tune the little screamer out — “it’s just the battery again.” So when it actually alarmed on 16% oxygen, his brain filed it under nuisance, same as it had for five days straight. His partner up top saw him go clumsy on the ladder, reaching wrong, and hauled him out by the harness line before he dropped. The air at the bottom was 16% oxygen. A few more rungs and we’d be writing his name.

No blame here — this is a good hand who got trained by his own equipment to ignore the one sound that meant you will die. That’s not a discipline problem; it’s a design problem. A device that cries wolf gets ignored by careful people, every time — that’s normal human wiring, not a character flaw. The fixes are real and cheap: replace dying batteries now, make the “you’ll die” alarm impossible to confuse with the “charge me” chirp, and treat a confined space like the permit-required space it is under 1910.146 — test, ventilate, attend, rescue plan. And notice who caught it: the partner topside. The person closest to the work saw the hazard first. That’s not luck. That’s the whole system working the way it’s supposed to.

Before a shift this week, walk one “dead” space in your operation — an abandoned line, a capped-off room, a tank or pit you “never go in.” On paper it’s inert. Nellis died because a machine cut into an entry that had been written off and unwatched for eight years. Pick your equivalent, put a meter and a set of eyes on it, and write down what you find — before someone cuts into it blind. Abandoned is not safe. It’s just unwatched.
