In-person · Wilmington, DEElectrical safety training in Wilmington, DE
Northern Delaware packs a heavy sour crude refinery, an ethylene oxide plant beside the Delaware Memorial Bridge, the headquarters of Chemours and a fruit port into a few miles of the Delaware River. We train the electrical crews who keep those sites running, at your facility or in an in-person class we set up in Wilmington when you ask.
Private employers in Delaware are inspected by federal OSHA. Every class is live, on the 2027 edition of NFPA 70E, and taught by a Certified Safety Professional. Delaware electrical safety training requirements →
Among the teams we have trained in the last year
Four ways to train your Wilmington crew
Crews we train in and around Wilmington: refining, chemicals and industrial gases, port and cold storage, terminal construction, corporate and lab campuses, public employers.
What the class covers for Wilmington crews
Delaware City's coker, FCC and hydrocracker draw large contract crews during outages. We cover host and contract employer duties so every crew follows one electrical safety approach inside the gate.
Ethylene oxide and hydrogen production put electrical work inside classified areas with deluge systems and gas detection. We cover how flammable atmospheres change the planning for energized work.
Port warehouses and fruit terminals depend on large refrigeration compressors and reefer power. We cover isolating refrigeration motors and controls without losing product temperature in the rest of the building.
Edgemoor will add a wharf, cranes and yard power while the existing port keeps operating. We focus on when new equipment becomes energized and how construction and operations crews mark that line.

Delaware: what applies to your crews
Enforcement: federal OSHA
Delaware has no state plan. OSHA's Wilmington Area Office covers private employers, and state agencies, counties, school districts and towns, including the municipal electric utilities, have no OSHA coverage at all.
Licensing: Board of Electrical Examiners
The Board of Electrical Examiners in the Division of Professional Regulation licenses master, limited, journeyperson and apprentice electricians statewide, with special licenses for defined scopes such as HVAC or elevators. The board also licenses the private agencies that perform electrical inspections.
Where NFPA 70E fits
An OSHA inspector cannot cite NFPA 70E by itself, because OSHA does not enforce it. Delaware employers use it to show how they meet 1910 Subpart S and 1926 Subpart K, and OSHA can use the General Duty Clause to cite a recognized arc flash or shock hazard.
Wilmington's electrical work environment
The Delaware City Refinery opened in 1956 and was shut by Valero in November 2009. PBF Energy bought it for $220 million in 2010 and restarted it in October 2011, and it now runs heavy sour crude through a fluid coker, a catalytic cracker and a hydrocracker with about 570 employees. Air Products bought the refinery's hydrogen plant in 2020. A 2001 sulfuric acid tank explosion there killed one worker.
Croda's Atlas Point plant near New Castle makes ethylene oxide for consumer products and medical sterilization. Its 2018 release of nearly 2,700 pounds forced more than 3,000 neighbors to shelter in place, and an April 14, 2026 leak from a valve gasket brought new DNREC and OSHA investigations. Chemours, spun off from DuPont in 2015, keeps its headquarters in Wilmington.
The Port of Wilmington is North America's top port for imported fresh fruit, bananas and juice concentrate, with the largest dockside cold storage on the continent. Three miles upriver at Edgemoor, Enstructure and the Diamond State Port Corporation are developing a $635 million container terminal that received Army Corps permits in 2026, with phase one targeted for 2028.
Refinery, chemical plants and terminals on the Delaware River
These are the northern Delaware sites with the heaviest electrical work. Most sit within a short drive of Wilmington along the river.
| Site | What is there | Status |
|---|---|---|
| Delaware City Refinery PBF Energy | Heavy sour crude refinery with coking and cracking units on more than 5,000 acres. | Operating |
| Delaware City hydrogen plant Air Products | Hydrogen unit bought from PBF in 2020 that supplies the refinery. | Operating |
| Atlas Point plant Croda | Ethylene oxide plant near the Delaware Memorial Bridge, under DNREC and OSHA investigation after an April 2026 leak. | Operating |
| Chemours headquarters Chemours | Wilmington headquarters of the former DuPont performance chemicals business, spun off in 2015. | Operating |
| Port of Wilmington Diamond State Port Corporation | Leading North American port for fresh fruit and juice imports, with large dockside cold storage. | Operating |
| Delaware Container Terminal Enstructure and Diamond State Port Corporation | $635 million Edgemoor terminal with phase one targeted for 2028 and 1.2 million TEU at full buildout. | Under construction |
Delmarva Power and Delaware's municipal systems
Delmarva Power, an Exelon company headquartered in Newark, serves about 312,000 electric customers in Delaware and 203,000 in Maryland, plus about 129,000 gas customers in northern Delaware. Its territory covers roughly 5,000 square miles of the Delmarva Peninsula.
Nine Delaware towns run their own electric utilities, including Newark, Dover, Milford and Seaford. Those utilities are public employers, so their line and substation workers have no OSHA coverage. Large plants along the river take service at high voltage and run their own substations, and some, like Croda, also run on-site generation from landfill gas.

Questions from Wilmington employers
Can you train refinery contractors before a Delaware City turnaround?
We work for a Delaware town's electric department. Does OSHA cover us?
Our crews also work in Maryland and Pennsylvania. Do the rules change?
Does a Delaware journeyperson license make someone qualified under NFPA 70E?
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.”
