In-person · Chicago, ILElectrical safety training in Chicago, IL
Chicago runs one of the largest data center markets in North America, from the carrier hotel at 350 E Cermak to new hyperscale campuses on the edge of the metro. We train the electricians and technicians who keep that load running, at your facility or in an in-person class we set up in Chicago when you ask.
Illinois runs a state plan for public employees only. Private employers are inspected by federal OSHA. Every class is live, on the 2027 edition of NFPA 70E, and taught by a Certified Safety Professional. Illinois electrical safety training requirements →

Four ways to train your Chicago crew
Crews we train in and around Chicago: data center operations, data center construction, automotive and heavy manufacturing, transit and rail, hospitals, universities and venues, electrical contractors.
What the class covers for Chicago crews
Decades-old gear in carrier hotels, plants and high-rises may not clear a fault the way the arc flash study assumed. We cover how maintenance condition affects the risk assessment and when to treat a label as suspect.
Transit substations, UPS galleries and telecom battery plants put DC hazards in front of Chicago crews daily. The 2-Day Intensive covers DC systems and batteries in depth.
Chicago licenses supervising electricians and contractors, and Illinois has no statewide electrician license. Neither one makes a worker qualified under NFPA 70E. Our individual qualification form and documented Competency Check give the employer that record.
Vaults, tunnels and rooftop gear in a Chicago January add cold, wet conditions and limited egress to electrical work. We cover how those conditions change shock risk and the emergency response plan.

Illinois: what applies to your crews
Enforcement: federal OSHA
Private employers in Chicago fall under federal OSHA. The Illinois OSHA state plan covers state and local government workers only, so a city crew and a private contractor on the same job answer to different agencies.
Licensing: municipal
Illinois has no statewide electrician license. Chicago requires every electrical contractor to be owned by or employ a licensed supervising electrician, who must pass a city exam and renew each year.
Where NFPA 70E fits
NFPA 70E is not an OSHA regulation. It is the consensus standard employers and inspectors use to show how OSHA 1910 Subpart S and 1926 Subpart K are met, and OSHA can cite the General Duty Clause for recognized electrical hazards.
Chicago's electrical work environment
Chicago's electrical stock spans a full century. Ford has built vehicles at its Torrence Avenue plant in Hegewisch since 1924, the company's oldest continuously operated assembly plant. Downtown, the Lakeside Technology Center at 350 E Cermak packs high-density data halls into about 1.1 million square feet, and QTS runs an urban campus on South Ashland.
Underneath the city, the CTA moves trains on 600 volt DC third rail. ComEd sells the AC, and roughly 50 traction substations convert it. Hospitals, universities, McCormick Place and O'Hare add large electrical loads of their own.
Old gear is the common thread. A Chicago electrician regularly opens switchgear that is older than they are, with service records nobody can find. Condition of maintenance drives the hazard on that equipment, so our classes spend real time on it.
ComEd and the Chicago grid
ComEd, the Exelon utility, serves the City of Chicago and nearly all of northern Illinois. Every data center, plant and transit substation in this market interconnects with ComEd.
Large loads now wait. ComEd requires 10-year letters of credit for interconnections of 50 MW and up and is quoting some energization dates to 2032 or later (CBRE H2 2025). Developers are answering with on-site generation and battery storage, which adds paralleling gear and stored energy to sites that used to be simple utility feeds.

Questions from Chicago employers
Do you have a scheduled class in Chicago?
Can you train at a downtown carrier hotel without taking our team off the floor?
Our electricians hold Chicago licenses. Do they still need NFPA 70E training?
Do you cover DC traction and battery hazards?
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.”
