The Circuit Was Supposed to Be Dead

I hate graveyard shift.

I didn’t grow up around factories that run day and night. I never had to work “third shift” as a regular thing. But sometimes in construction, there are projects that can only happen in the middle of the night.

Hospitals. Airports. Critical systems that can’t simply be shut down while people are using them.

Defense contractors would sometimes take advantage of the annual two-week holiday period at the end of the year to do round-the-clock maintenance, improvements, and changes to their facilities.

It could be a boom for contractors trying to get a lot of work done before the year closed.

It could also be a bust for workers who wanted to spend time with their families and didn’t have healthy boundaries with their employers.

And then there were the guys who loved every hour of overtime they could get.

Anyway. I digress.

I was working graveyard shift at a Kaiser Permanente facility in Pasadena. Part of the work was changing out light fixtures in the middle of the night.

I had only been on that project for a couple of weeks.

My sleep pattern hadn’t adjusted well. My attention and awareness weren’t where they normally would have been.

And did I say I hate graveyard shift?

I wanted to get the work done.

Looking back, what happened reminds me of something out of a Tom Clancy novel.

Not because there was one gigantic catastrophic mistake.

Because a bunch of little things that meant almost nothing by themselves began lining up.

We had a lockout/tagout procedure that we were using. The circuit I was working on was supposed to be dead.

But the electrical box I needed to open was in a cluster of boxes.

The cover and label that appeared to belong to the box I was opening actually didn’t correspond correctly to that box.

So the first piece of information I was relying on was wrong.

Then I used an inductive voltage tester.

We called them tic tracers.​

It indicated that the circuit was dead.

Here is one of the parts that bothers me most when I look back on it.

I already knew tic tracers could give you false-negative readings. I had even shown apprentices examples where that could happen.

I knew better.

But that night the tester confirmed what I already expected to be true.

The circuit was supposed to have been locked out.

The label appeared to identify it.

The tic tracer said dead.

Everything seemed to agree.

And because everything appeared to confirm what I already believed, I stopped asking questions.

Then I added another problem.

Good common sense would have told me not to simply cut through the conductors together. Especially when working around 277-volt lighting circuits.

One conductor at a time.

Control what you’re touching.

Control your body position.

Respect uncertainty.

But I was tired.

I hated graveyard.

I wanted to finish.

So instead of slowing down because the consequences were high, I sped up because I wanted to get the job done.

I put my cutters into the wires.

One of the conductors that was supposed to be dead was hot.

I got hit.

If you’ve never been hooked up electrically, it is difficult to describe.

You know you’re being shocked.

You can feel the cycles.

But your muscles lock and your body doesn’t necessarily obey the simple command:

Let go.

Then another small detail suddenly became very important.

I was working from roughly a ten-foot ladder above the ceiling. I was touching metal ceiling wires holding the T-bar ceiling.​

And there was a sprinkler line behind me.

Normally that sprinkler line meant nothing.

But now I couldn’t push myself cleanly away.

I had put myself into a physical position where my escape path was compromised.

Another little thing.

Meaningless by itself.

Very meaningful once everything else had gone wrong.

Eventually I managed to get my legs to buckle.

My highly sophisticated escape strategy became:

Fall off the ladder.

I came down very ungracefully, yelling in pain and anger.

My foreman and coworkers rushed over.

At first I felt okay.

Of course I had adrenaline pumping through me.

I had some minor burns on my hands and arms.

The safe decision was to get checked rather than assume that because I felt okay immediately afterward, everything actually was okay.

So my graveyard shift ended with a middle-of-the-night ambulance ride to an all-night medical facility roughly forty minutes away in the West San Fernando Valley.

And I had plenty of time during that ride to think about what had happened.

Because there wasn’t one mistake.

There was a stack.

The Chain, Link by Link

When something goes wrong, people naturally want to find the mistake.

The one thing that caused it.

The villain.

The tester failed.

The label was wrong.

He was tired.

He rushed.

He didn’t follow the procedure.

Finding one villain makes the world feel simple.

If you can name the single cause, you can fix the single cause.

Problem solved.

Lesson learned.

Move on.

But for serious failures, that explanation is often incomplete.

And treating it as complete can prevent you from learning what really happened.

Here is the actual chain from that night.

I was still adjusting to graveyard shift. My sleep was off. My attention was degraded.

Link one.

The lockout/tagout process created an expectation that the circuit was safe. That expectation was reasonable. But it meant I approached the box already believing it was dead.

Link two.

The cover and label didn’t correspond correctly to the box I was opening. The information I was relying on was wrong.

Link three.

The tic tracer gave me a false-negative reading.

And I accepted it.

Even though I knew, intellectually and from experience, that tic tracers can give you false negatives.

Link four.

Because the label, the lockout, and the tester all agreed, I stopped asking questions.

Link five.

I was impatient.

I wanted to finish.

Instead of cutting one conductor at a time, I cut through them together.

Link six.

My body position was compromised.

Working from a ladder.

Touching metal.

A sprinkler line behind me.

When I needed to escape, the path wasn’t clear.

Link seven.

Any single one of those might have been survivable.

Break any one of several links and the outcome might have been different.

A correct label.

A verification method that caught the energized conductor.

Slower cutting.

Better body position.

More margin.

Any one of those could have interrupted the chain before all seven links lined up.

None of them, alone, tells the whole story.

Together, they put me in that ambulance.

Where Else Is This Happening?

The electrical accident is a very specific story.

But the pattern is not specific at all.

It shows up everywhere people face meaningful consequences.

A business can have a slightly inaccurate number.

• Plus a weak assumption nobody checked.
• Plus an employee afraid to speak up.
• Plus a rushed decision.
• Plus no margin for error.

What looked like five minor issues becomes a serious financial problem.

A relationship can have one unspoken irritation.

• Then another.
• Then a bad assumption about what the other person meant.
• Then avoidance.
• Then fatigue.
• Then one badly timed comment.

And suddenly two people are fighting about something much larger than the sentence that triggered it.

The sentence didn’t cause the fight.

It was just the last link in a chain that had been building for weeks.

A martial artist can have poor position, plus fatigue, plus ego, plus an awkward limb, plus refusal to tap and reset.

One more movement creates the injury.

The movement gets blamed.

But the movement was just the last link.

Personal finances can have one subscription nobody remembers, plus one balance carried over, plus one unexpected expense, plus no emergency cushion.

The person who felt “basically fine” is suddenly in trouble.

The unexpected expense gets the blame.

But the vulnerability was built one small decision at a time.

This is not paranoia.

The lesson is not that every tiny problem is an emergency.

Most small problems stay small.

Most imperfect conditions don’t cascade.

You don’t need seventeen verification steps before you decide what to eat for lunch.

The lesson is that the number and interaction of small problems matters.

A single weak signal may be manageable.

Two may deserve attention.

Three or four interacting weaknesses may mean:

Stop.

Reset.

Verify.

Create margin.

Remove one variable before another arrives.

What Proves Me Wrong?

There is a second useful layer underneath all of this.

That night I concluded:

The circuit is dead.

I had evidence.

Lockout and tagout.

Label.

Tester.

I wasn’t guessing randomly.

I was building a conclusion from information.

But here’s the problem.

Three different things appeared to confirm the same conclusion: the lockout, the label, the tester.

What I failed to appreciate was that each one could still be wrong in its own way.

The label was on the wrong box.

The tic tracer can give false negatives.

Whatever had gone wrong upstream, the conductor I was about to cut was still energized.

They looked like three independent confirmations.

In this particular situation, none of them was reliable.

A sophisticated conclusion built on bad information is still a bad conclusion.

I should have asked a different question.

Not just:

What evidence supports what I already believe?

But:

What would prove me wrong?

What test would survive even if my assumption was incorrect?

What independent check doesn’t care what I expect to find?

That question matters far beyond electrical work.

A leader making a decision under pressure.

A business owner evaluating an opportunity.

A parent judging a situation with their kid.

A partner interpreting something the other person said.

The mind naturally seeks confirmation.

It is fast.

It is comfortable.

It lets you move forward without stopping.

But it also lets you walk straight into a problem that better questions would have revealed.

Especially when the conclusion is convenient.

Especially when the conclusion lets you move faster.

Especially when you want it to be true.

Break One Link

I don’t tell this story to scare anyone.

I don’t tell it to suggest that I’m unusually tough for surviving it.

I tell it because the pattern put me in an ambulance, and I keep seeing the same pattern in places where the consequences are less visible but the damage is just as real.

Catastrophe rarely announces itself as catastrophe.

It announces itself one small thing at a time.

The wrong label.

The tired decision.

The compromised position.

The test you trusted because it told you what you wanted to hear.

None of them feels like an emergency in the moment.

Each one feels manageable.

Probably fine.

Something you’ll get to later.

Something that won’t matter unless something else goes wrong.

And then something else goes wrong.

So here is the practical question.

When something consequential in your life is starting to feel sloppy, rushed, uncertain, or “probably fine,” ask yourself a few things.

What is already wrong?

Not catastrophically wrong.

Just imperfect.

What label, assumption, relationship, number, condition, tool, schedule, or piece of information is already weaker than you would like?

What am I assuming?

Separate what you know from what you think is probably true.

What am I using as confirmation?

Is it genuinely independent evidence?

Or is one assumption being repeated back to you in several forms?

What pressure is making me move faster?

• Fatigue?
• Impatience?
• Money?
• Embarrassment?
• Deadline?
• Ego?
• Wanting to go home?

How much margin do I have left?

If one more unexpected thing happens, can I absorb it?

What small thing can I fix right now?

You may not need to solve everything.

Breaking one link in the chain may prevent the chain from completing.

The goal isn’t omniscience.

You will never catch every variable.

You will never have perfect information.

The goal is interruption.

Catching the chain while you can still break it, before the next variable arrives and the problem becomes something much harder to solve.

⚔ The Dojo Drill: Find the Collecting Things

Pick one area of your life where the consequences of being wrong are meaningful.

• Health.
• Money.
• Work.
• A relationship.
• A major decision you’ve been putting off.

Don’t look for the giant obvious danger.

Look for the small things that have been quietly accumulating.

The thing you’ve been ignoring.

The assumption nobody checked.

The shortcut that became normal.

The conversation being postponed.

The number that “looks close enough.”

The maintenance you’re putting off.

The fatigue you’re pretending doesn’t matter.

The backup you don’t have.

The margin that has disappeared.

Write them down.

Don’t solve them all.

Just pick one link and break it.

Make the call.

Run the real test.

Ask the question you’ve been avoiding.

Create the margin you’ve been borrowing against.

Fix the one thing that, if another variable gets added to the pile, you’ll wish you had fixed already.

Most of the time, nothing catastrophic happens.

The small things stay small.

The chain never completes.

You get away with it.

But you don’t always.

The circuit was supposed to be dead.

The label appeared to say so.

The tester agreed.

I was tired and wanted to go home.

It was probably fine.

It wasn’t.

Don’t wait for the small things to become one big thing.

Catch the chain while you can still break it.

📚 Leader’s Library

​James P. Carse — Finite and Infinite Games​

Why?

Carse offers a useful way to understand why two people can participate in the same activity while pursuing completely different goals.

Some games are finite: there is a winner, a rank, a score, a promotion, or some other defined outcome.

Others are more infinite: the purpose is to keep learning, participating, adapting, and continuing the game.

That distinction applies far beyond sports. It can help you understand coworkers, training partners, competitors, leaders, relationships—and yourself. Before assuming someone is playing badly, it is worth asking whether they are even playing the same game you are.

A strong addition to the library for anyone interested in leadership, perspective, relationships, lifelong learning, and becoming better at understanding what other people are actually trying to accomplish.
