Electrical safety: what the federal data actually says

The honest calibration: uncommon, and more dangerous than average

Electrical safety content tends to open by implying your house is about to burn down. The federal estimates do not support that, and they support something more useful — a risk that is comparatively uncommon but disproportionately serious when it occurs.

According to the US Consumer Product Safety Commission, 2019–2021 Residential Fire Loss Estimates (May 2024), retrieved 2026-09-05: "An estimated annual average of 17,100 fires was attributable to electrical distribution equipment (e.g., installed wiring, lighting, etc.). This is 4.9 percent of the estimated annual average number of residential fires for this period. The annual average death estimate is 150 (6.0 percent of average annual estimated residential fire deaths); and the injury estimates averaged 680 (6.1 percent of the estimated annual average of residential fire injuries)."

Set that against the other causes in the same report. Cooking accounted for an estimated annual average of 157,100 residential fires, 44.6% of the total. Heating and cooling equipment accounted for 37,600, 10.7%. Electrical distribution equipment, at 17,100 and 4.9%, is well behind both. Anyone telling you electrical faults are the leading cause of house fires is wrong, and the correction is not a reassurance — it is the first half of the finding.

The second half is where the attention belongs. HyreElectrical calculation from CPSC’s published shares: electrical distribution fires are 4.9% of residential fires but 6.0% of residential fire deaths and 6.1% of injuries. Dividing the death share by the fire share gives roughly 1.22 times the average lethality per fire. That is arithmetic on CPSC’s percentages, not a separate CPSC finding, and it is a modest ratio rather than a dramatic one — which is precisely why it is worth stating accurately instead of inflating.

Why would an electrical fire be more dangerous than an average one? The most plausible explanation, and it is our interpretation rather than CPSC’s, is where these fires start and when they are noticed. A cooking fire begins in an occupied room with somebody standing next to it. An electrical fire frequently begins inside a wall, a ceiling or an attic, and the same pattern appears in NFPA’s independent origin data, which we set out on the repair page. Two federal bodies, two datasets, one consistent implication: detection is the weak link, not ignition.

Inside the electrical category, the permanent system dominates

"Electrical fire" is often imagined as a faulty appliance or an overloaded power strip. CPSC’s breakdown of what is inside the electrical distribution category points somewhere less convenient.

According to CPSC Table 4a, 2019 column: installed wiring accounted for an estimated 7,500 fires; other electrical distribution 2,700; receptacles and switches 2,100; cords and plugs 1,500; light fixtures 1,400; panel boards 700; lamps and light bulbs 600; meters 500; and transformers 100. CPSC Table 4a, 2019 column. These are single-year estimates for 2019, not the 2019–2021 annual averages quoted elsewhere on this page, and they are estimates derived from NFIRS rather than a census of fires.

HyreElectrical calculation: installed wiring alone is about 44% of that 2019 breakdown — the largest single line by a wide margin, and larger than cords, plugs, lamps, fixtures and light bulbs combined. The permanent wiring system, receptacles and switches together account for the clear majority.

The consequence for a homeowner is a reallocation of attention. Unplugging space heaters and replacing frayed cords is worth doing and is not where the weight of this data sits. The permanent system — the part you cannot see, cannot unplug and did not choose — is. That is an argument for having the installation looked at properly rather than for buying anything, and it is the reason the useful next step in an older house is a scoped electrical inspection rather than a shopping list.

Where HyreElectrical stops and the electrician starts

HyreElectrical is an independent information site. We read the federal fire loss report, the model-code section, the municipal fee sheet and the utility tariff ourselves, and we publish what they say with the publisher, the document and the retrieval date attached — and we publish what we could not verify rather than rounding it into a confident sentence.

We do not perform, supervise, inspect or warrant electrical work, and we publish no procedure that involves opening a panel, testing a circuit or touching a conductor. We hold no dataset of fires, inspections or incidents; every figure on this page is a named third party’s published estimate, or arithmetic we performed on one and have labelled as ours. We take no payment for placement, ranking or a favourable mention.

Our contractor store holds 16,369 electrical companies across 5 verified states — Florida 12,114, Utah 1,489, Nevada 1,066, California 903, Texas 839 — counted on 5 September 2026, 74% of it Florida. A research sample for five states, not a national census and not a recommendation of any firm. Verifying a licence on the issuing board’s own register, using the licence lookup, is the check that counts.
