Does Your Property Insurance Cover a Lab Equipment Breakdown?

Usually not the breakdown itself. Standard commercial property insurance covers direct physical damage from a covered peril, a fire, a burst pipe, a storm. Mechanical failure, an electrical surge, or operator error inside a machine is equipment breakdown, and that is a separate coverage line. A lab whose centrifuge or analyzer fails on its own finds that property insurance does not pay the repair or replacement, because nothing the property policy calls a peril actually happened.

What Property Insurance Covers, and What It Excludes

A commercial property policy responds to direct physical loss or damage from a covered cause: fire, water from a burst pipe, wind, theft, and similar named or open perils. If a covered peril damages the lab’s equipment, the property policy pays. What it specifically excludes is loss caused by the equipment’s own mechanical or electrical failure. That exclusion is deliberate and standard, because internal breakdown is a different kind of risk from an external peril, and it is the province of a separate line, equipment breakdown coverage, sometimes still called boiler and machinery.

The distinction is easy to miss because the result looks the same: an expensive machine is down and needs repair or replacement. But the property policy does not ask what it costs; it asks what caused it. A fire that destroys an analyzer is covered. The same analyzer failing because a motor burned out or a power surge fried a board is not, unless equipment breakdown coverage is in place.

Why a Lab Feels This Gap More Than Most

Laboratory equipment is concentrated, specialized, and expensive, and the operation depends on it running continuously. A mid-volume analyzer or a sequencing platform can carry a significant replacement value, and when one fails the loss is not only the repair. It is the downtime: testing stops, results stop flowing, and revenue stops until the machine is back. Standard property coverage excludes the mechanical failure that causes that downtime, and the business interruption that follows an equipment breakdown is often carried under the equipment breakdown line rather than the property line. A lab relying only on property coverage has insured the building and the contents against perils and left the most likely cause of an expensive outage uncovered.

This is one of the four core risk areas a lab program has to address, and the property and equipment piece is mapped in what insurance a CLIA-certified lab needs. How heavily it weighs depends on the lab’s automation and scale, which shifts across the stages in insurance by lab revenue stage.

What Equipment Breakdown Coverage Adds

Equipment breakdown coverage responds to the sudden, accidental failure of covered equipment from internal causes: mechanical breakdown, electrical arcing or surge, motor burnout, and in many forms operator error. It typically pays to repair or replace the equipment and can include the business interruption and spoilage that follow, the last of which matters for a lab holding temperature-sensitive reagents and specimens that a refrigeration failure can ruin. It is usually written as a separate policy or as an endorsement to the property program, and for a lab running automation it closes a gap the property policy leaves wide open.

The spoilage angle is worth a specific look. A refrigeration or freezer breakdown can destroy reagents and stored specimens, and that loss rides on the equipment breakdown line, not the property line, in most programs.

What to Do Now

Read your property policy for its mechanical and electrical breakdown exclusion, and confirm whether you carry a separate equipment breakdown line or endorsement. Schedule your major analyzers and refrigeration to actual replacement values, and confirm the breakdown coverage includes the business interruption and spoilage that an outage would trigger, not just the repair. For a lab running on automation, this is one of the cheaper gaps to close relative to what a single analyzer failure can cost.

Before your next renewal, separate the question of damage from a peril from the question of the equipment failing on its own, and confirm a policy answers each. A specialty review through Tower Street Insurance can confirm your lab’s analyzers and cold storage are covered for breakdown, not just for fire and water.
