In-person · St. Louis, MOElectrical safety training in St. Louis, MO
St. Louis builds fighter jets and trucks, runs one of the busiest inland river port systems in the country and sits next to a 345,000 barrel-a-day refinery across the Mississippi. We train the electrical crews who build and maintain those plants, at your facility or in an in-person class we set up in St. Louis when you ask.
Private employers in Missouri are inspected by federal OSHA. Every class is live, on the 2027 edition of NFPA 70E, and taught by a Certified Safety Professional. Missouri electrical safety training requirements →
Among the teams we have trained in the last year
Four ways to train your St. Louis crew
Crews we train in and around St. Louis: aerospace and defense, automotive, refining, utilities and generation, federal and secure facilities, municipal and public authorities.
What the class covers for St. Louis crews
New fighter production buildings go up next to operating lines with test equipment, cranes and large motor loads. We teach where construction power ends and an operating facility's electrical safety program takes over.
A paint shop rebuild at an assembly plant brings contractors onto MCCs and robotic cells with several energy sources. Our classes focus on lockout, verification of absence of voltage and host and contractor coordination.
Crews that move between a Missouri plant and the Wood River refinery in Illinois deal with different site rules and different public-sector OSHA coverage. We build examples around refinery process loads as well as factory gear.
Missouri has no statewide electrician license, so the employer's qualification decision carries more weight. We give you the documentation trail that shows each person was trained for the tasks they do.

Missouri: what applies to your crews
Enforcement: federal OSHA
Missouri has no state plan, so private employers answer to federal OSHA, which has area offices in St. Louis and Kansas City. State and local government workers have no OSHA coverage at all. Crews working on the Illinois side fall under federal OSHA too, while Illinois public employees are covered by IL OSHA.
Licensing: local
Missouri has no statewide electrician license. The state offers a voluntary statewide electrical contractor license. The City of St. Louis licenses electrical work through its Committee of Electrical Examiners, and St. Louis County runs its own program.
Where NFPA 70E fits
OSHA does not enforce NFPA 70E. Employers use it to show how they meet the electrical requirements in OSHA 1910 Subpart S and 1926 Subpart K, and OSHA can cite the General Duty Clause for a recognized electrical hazard.
St. Louis's electrical work environment
Aerospace sets the pace. Boeing's defense operations at St. Louis Lambert are in a $1.8 billion expansion for the F-47 next-generation fighter, with the first aircraft due by 2030. In St. Charles County, GM's Wentzville Assembly employs more than 4,000 people building the Chevrolet Colorado, GMC Canyon and full-size Express and Savana vans, and GM announced a $157 million paint shop overhaul there in July 2026.
North of downtown, the National Geospatial-Intelligence Agency opened its $1.7 billion Next NGA West campus in 2025. Across the river in Roxana, Illinois, Phillips 66's Wood River refinery processes 345,000 barrels a day, and Phillips 66 took full ownership of it in a 2025 deal. The region's port system spans about 70 river miles on both banks, which keeps conveyor and dock electricians busy in two states.
Data centers are arriving more slowly here than elsewhere. A 120 MW, $3 billion project in the city's Armory district is moving forward under a conditional use permit, but St. Charles made its ban on large data centers permanent in May 2026, St. Charles County passed a six-month moratorium that July and St. Louis County is drafting its own rules.
Aerospace, auto, federal and energy sites around St. Louis
These are the large sites where St. Louis electrical crews are busiest right now. Several are expanding at the same time.
| Site | What is there | Status |
|---|---|---|
| Boeing St. Louis F-47 expansion Boeing | $1.8 billion, million-plus square foot expansion for the F-47 fighter, with first delivery targeted by 2030. | Under construction |
| Wentzville Assembly General Motors | More than 4,000 workers build midsize pickups and full-size vans; a $157 million paint shop overhaul was announced in July 2026. | Operating |
| Next NGA West National Geospatial-Intelligence Agency | $1.7 billion campus in north St. Louis that opened in 2025. | Operating |
| Wood River refinery Phillips 66 | 345,000 barrel-a-day refinery in Roxana, Illinois, fully owned by Phillips 66 after a 2025 deal. | Operating |
| Labadie Energy Center Ameren Missouri | Four-unit, 2,372 MW coal plant in Franklin County, now planned to run until 2042. | Operating |
| Callaway Energy Center Ameren Missouri | 1,194 MW nuclear plant, Ameren Missouri's only nuclear unit. | Operating |
| Armory district data center Not disclosed | 120 MW, $3 billion project in Midtown moving forward under a conditional use permit. | Planned |
Ameren Missouri and the growth in large loads
Ameren Missouri serves about 1.3 million electric customers in roughly 60 counties from its St. Louis headquarters. Its fleet includes the Labadie and Sioux coal plants, the Callaway nuclear plant, the Taum Sauk pumped storage plant and combustion turbines close to the city at Venice and Maryland Heights. That mix keeps utility and contractor crews working on generation, switchyards and substations within an hour of downtown.
Ameren's 2026 resource plan reflects how much demand is expected. It lists nine new gas plants over 20 years, up from two in the 2023 plan, keeps all four Labadie units running until 2042 and counts 40 potential large data centers in its territory. Ameren says Missouri's Senate Bill 4 requires data centers to pay for the infrastructure that serves them, so much of the new medium-voltage work will be built for specific customers.

Questions from St. Louis employers
Can you train contractors working on the Boeing expansion?
We are a St. Louis County municipality. Does OSHA apply to us?
Our crews work in both Missouri and Illinois. Does that change the training?
Is a City of St. Louis electrical license enough to be qualified?
Does finishing the class make someone a qualified electrical worker?
What the people in the room say
“Virtual can never replace hands-on, but the engagement from our instructor and the class made it feel more engaging than some in-person courses I've taken.”
“Probably one of the most useful safety courses I've ever attended. Rick genuinely cares about people and their well-being.”
“This is the 2nd arc flash training course I've taken and the class was amazing. I feel like I'm leaving the training safer than before I took this class.”
