In-person · Denver, COElectrical safety training in Denver, CO
Denver is Colorado's network and logistics hub, with the state's main carrier hotel downtown and a new 170,000 sq ft CoreSite building due by the end of 2026. We train the electricians and technicians who keep the city's data centers, hospitals and airport running, at your facility or in an in-person class we set up in Denver when you ask.
Private employers in Colorado are inspected by federal OSHA. Every class is live, on the 2027 edition of NFPA 70E, and taught by a Certified Safety Professional. Colorado electrical safety training requirements →
Among the teams we have trained in the last year
Four ways to train your Denver crew
Crews we train in and around Denver: data center construction and operations, airline and airport, hospitals, public agencies, electrical contractors, energy and utilities.
What the class covers for Denver crews
Colorado has no state plan, so city, county, special district and school district electricians are outside OSHA entirely. For those crews, a written NFPA 70E program is the only structure there is. We train public crews to the same standard as private ones.
Colorado licenses electricians statewide through DORA, and continuing education is built around the NEC. A licensed electrician can be fully current and never have had arc flash training. The employer has to train and document NFPA 70E qualification.
New data hall construction and commissioning in the metro puts general contractors, electrical subs and commissioning agents on the same site. We cover how host and contract employers share responsibility for energized work.
Baggage systems, jet bridges, ground power and rail traction power add equipment owned by more than one employer. We build examples around that kind of equipment.

Colorado: what applies to your crews
Enforcement: federal OSHA
Colorado has no state plan. Federal OSHA covers private employers through its Denver and Englewood area offices under Region 8. Public employees of Colorado cities, counties, special districts and the state have no OSHA coverage at all.
Licensing: state license required
The State Electrical Board within the Department of Regulatory Agencies (DORA) licenses residential wiremen, journeyman and master electricians and registers apprentices and contractors. Renewal requires 24 hours of continuing education per three-year cycle, built mostly around the NEC.
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 requirements are met, and OSHA can cite the General Duty Clause for recognized electrical hazards.
Denver's electrical work environment
Downtown Denver's network traffic runs through 910 15th Street, where CoreSite's DE1 is the region's main carrier hotel and peering point. CoreSite is now building DE3 on Race Street in north Denver. Most of the metro's larger colocation campuses sit in the suburbs, with QTS and Flexential in Aurora and EdgeConneX, DataBank and Equinix in Englewood and Centennial.
The city's largest employers tell you where the rest of the electrical work is. After the City and County of Denver and the public schools, the list runs through the State of Colorado, Denver Health and United Airlines, which has more than 7,000 people here. Denver International Airport, about 20 miles from downtown, is its own small city of baggage systems, jet bridges and ground power.
Denver also anchors a Front Range economy of energy, aerospace and logistics. Electricians here move between downtown high-rises, airport work and suburban industrial parks, often in the same month.
Xcel Energy
Xcel Energy serves Denver through its Colorado subsidiary, Public Service Company of Colorado, which was formed in 1923 and is based in Denver. In March 2026 Xcel proposed a large-load tariff that would set separate, higher rates for big users such as data centers, as Colorado's data center count reached 56 with many more under construction.
Xcel is also building the $1.7 billion Colorado Power Pathway across the eastern plains, with most work expected to finish by 2027. For your crews, more transmission and more large-load customers mean more customer-owned substations and medium-voltage gear in the metro.

Questions from Denver employers
Do you have a scheduled class in Denver?
We are a city department. Does OSHA apply to us?
Our electricians hold Colorado licenses. Do they still need NFPA 70E training?
Can you train at a suburban data center campus?
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.”
