Resident safety notice · Burlingame, California
A resident reports experiencing an electrical issue involving the heaters that raised concern about a potential fire while living here. Photographs supplied in September 2026 also show a GTE Sylvania panel whose equipment label specifies Zinsco breaker types. The electrical system should be evaluated in person by a licensed electrician.
If you smell burning, hear buzzing or arcing, see smoke, or find the panel unusually hot: move away and call 911 or the serving utility. Do not remove the cover.
Resident-reported incident
This is a firsthand resident account. It is presented separately from the photographic record and has not been characterized here as a professional determination of cause. The report, together with the photographed equipment, is the reason this page asks for an independent licensed inspection and written disclosure.
What the photographs establish
The panel face carries a visible “SYLVANIA” and “GTE Sylvania” label.
The interior equipment label instructs the use of listed Zinsco breaker types.
The photographed label identifies the load center as 125 amps maximum.
The bus, terminations, conductor condition, grounding, bonding, and trip performance are not visible in these photos.
A separate photograph shows an uncovered wall box with multiple wire connections wrapped in red tape.
The resident identifies this open wall box as the area where the burnt smell was strongest.

Additional reported hazard
That temperature presents a serious scald risk. A CDC-hosted study states that exposure to 140°F water can cause a serious burn in about three seconds. Children, older adults, and people with reduced mobility or sensation are especially vulnerable.
Property management should have a qualified plumbing professional verify temperatures at the taps and correct the delivery temperature. Where hotter storage temperatures are needed for water-system health, the CDC advises using thermostatic mixing valves to reduce the temperature delivered at faucets, showers, and tubs.
Safety sources: CDC-hosted tap-water scald study, U.S. Consumer Product Safety Commission, and CDC water-temperature guidance.
Requested action
Request an on-site evaluation by a licensed electrical contractor who has no financial interest in the transaction.
Ask the electrician to identify the exact panel and breaker series and examine the bus, connections, overheating evidence, breaker seating, and operation.
Confirm the service rating, calculated load, grounding and bonding, and whether required GFCI or AFCI protection is present.
Ask the owner or manager for permits, inspection records, prior electrical reports, and invoices for any panel or breaker work.
If deficiencies are found, request a scope, permit requirements, cost estimate, and completion date from a qualified contractor.
Request written verification of tap temperatures and documentation of any thermostat, tempering-valve, or plumbing corrections made to reduce scald risk.
This page contains a resident's firsthand account, a resident-reported water-temperature measurement, a resident-identified incident location, and a photographic record.

This page is not an electrical or plumbing inspection, engineering report, code determination, or professional finding about the cause of the reported smell. Qualified professionals with access to the property must verify present conditions and required corrections.
