NFPA 70E Toolbox Talk Library
Thirteen talks, each built on a real fatality investigation with the report number on the page. Ten minutes, three questions, and a sign-in grid.

01Why these use real cases
Most toolbox talks are a paragraph of policy restated as a bullet list. Crews sit through them, sign the sheet, and nothing changes — because nothing in the talk was about a person.
Every talk in this library is built on an actual NIOSH FACE investigation. Real people, real equipment, real reports you can look up. The report number and source are printed at the bottom of every page, so if someone in your crew doubts it, they can go read it themselves. That matters more than any statistic I could put on a slide.
What consistently lands in my classes is not the fatality. It is the detail just before it: the meter in his pocket he never used, the drawing that was wrong, the ladder they were putting away when the job was already over. Every one of these men believed he was safe in the moment it happened. That is the part worth ten minutes.
02The library
Click any talk to download the PDF. Each one is a single page: what happened, why it happened, what the standard requires, three discussion questions, space for your crew's own commitments, and a sign-in grid.
Test Before Touch
The meter was in his pocket. He never used it.
The Circuit That Wasn't On The Drawing
He turned off the switch, opened the breaker, and checked the prints. All three were wrong.
Reaching Across The Live Bus
He was warned about the wires that morning. He reached over them that afternoon.
Wrong Meter, Wrong Voltage
A 600-volt meter on a 14,400-volt circuit. He lived 18 days.
Alone, At Night, With No Meter
The panel was open. That is not the same as dead.
The Bucket Went Up Into The Lines
Two men, one bucket, one reach. Nobody called the utility.
The Master Electrician Who Was Also The Safety Guy
Twelve hours the day before. On site by 5 a.m. Reaching into an energized junction box.
A Forty-Eight Foot Aluminum Ladder And A Gust Of Wind
Ten feet eight inches from the line to the wall. A father and his son.
“We Thought That One Was A Ground”
The operator raised the boom instead of running the winch.
One Hundred And Ten Volts Killed Him
He grabbed a light fixture chain so the bucket would not hit it.
The Temporary Power Was Inspected. It Was Never Tested.
Two forty-amp fuses protecting fifteen-amp receptacles. A GFCI that would not trip.
Chipping Concrete Off A Live Duct Bank
Three conduits. Four cables each. Seven thousand two hundred volts.
One Circuit Left Hot Inside A Locked-Out Substation
He installed the temporary service himself, months earlier.
The complete library as a single 13-page PDF — print it once, keep it in the gang box, and work through one a week for a quarter.
- Read the incident out loud. Do not summarize it. The details are what make it land.
- Stop and let it sit. Someone will say “I've done that.” That is the whole point of the exercise.
- Ask the three questions and wait. The silence is uncomfortable and productive. Do not fill it.
- Write down what your crew commits to in their words, on the sheet, in front of them.
- Bring the sheet back next time and ask whether it happened. A commitment nobody follows up on teaches the opposite lesson.
03A note on the facts
Every incident narrative is drawn from the published NIOSH or state FACE report cited at the bottom of that page. Victims' names are not used. The wording is mine; the facts are theirs. If you find a discrepancy between one of these talks and the source report, the report governs — tell me and I will correct the talk.
These are teaching documents, not legal or engineering determinations. Adapt each one to your site, your equipment, and your program before you use it.
Ten minutes a week keeps hazards visible. It does not produce qualified persons, and it is not a training program. If your electrical safety program needs building or rewriting, that is what I do — with sample excerpts from real deliverables published so you can read the actual writing first.
