Defective Construction Equipment and Tools in Michigan

When a nail gun fires without a trigger pull, a ladder rail buckles, a lanyard tears, a saw guard sticks open, or a scissor lift drops, workers’ comp responds the same way it does to any injury. Comp can’t hold anyone accountable, and manufacturers don’t get the immunity your employer does. Product claims let construction workers hurt by failed equipment pursue the damages comp never pays, and they can exist even when nobody on the site did anything wrong, though a failed tool is the beginning of the investigation, not proof of a defect by itself.

The problem is not rare. NIOSH estimates nail guns alone send tens of thousands of people to emergency rooms every year, most of them injured on the job, and its research shows contact-trigger models injure at roughly twice the rate of sequential-trigger designs, a design choice litigated for decades.

The Equipment That Fails, and How

Powder and pneumatic tools: nail guns that double-fire or fire on bump contact, grinders whose wheels shatter, saws whose guards bind or whose brakes fail. Fall protection: harnesses, lanyards, self-retracting lifelines, and anchors that hold a catalog rating but not a falling body, a category governed by detailed industry standards precisely because failure means a fall. Access equipment: ladders that buckle within rated load, scaffold components that crack, scissor and boom lifts that collapse, drift, or tip from defects in hydraulics and controls. Heavy iron: quick couplers that drop buckets, brakes and interlocks that fail, protective structures that do not protect; those cases overlap with our heavy equipment accidents page. And guarding and warnings: machines and tools sold with guards that invite removal, instructions that bury the hazard, warnings that never reach the end user on a job site. Component parts count too: Michigan law treats the failed valve, switch, or buckle as a product in its own right, which can put a component maker in the case alongside the brand on the housing.

Recalls tell part of this story, and we check recall and service-bulletin history in every equipment case. But a product does not need a recall to be defective, and a recall does not automatically prove your claim; the case is ultimately built on the failed unit itself.

How Michigan Product Law Works

Michigan product liability has specific statutory rules, and we explain them to clients at the start.

The claim forms. A manufacturing defect claim says your unit was not reasonably safe when it left the maker’s control. A design defect claim says the product line itself was unreasonably dangerous, and Michigan weighs whether a safer, feasible alternative design existed that would not have impaired the product’s usefulness- the nail gun trigger question in statutory form. Warning claims ask whether the maker adequately warned of dangers it knew or should have known, measured by the knowledge available when the product left its control. Two defenses come standard: that the risk was obvious or common knowledge, and that the user was a “sophisticated user” who knew the hazard. Michigan’s statute has an answer worth knowing on that second one: an employee who lacked actual knowledge of the specific hazard is not a sophisticated user just because his employer or trade should have known it.

Timing rules. Michigan gives product liability actions a three-year limitations period, and it judges design and warnings by the era of manufacture, not the year of your injury; manufacturers generally have no duty to recall or retrofit old equipment, though duties of reasonable care can continue after sale in some circumstances. Construction equipment lives for decades, so two more rules shape real cases: a product in use for ten years or more requires the plaintiff to prove the case without the benefit of any evidentiary presumption, and compliance with applicable government standards gives the defense a rebuttable presumption of non-liability. None of these ends a case by itself; all of them shape how it must be built.

Misuse and alteration. The defense in nearly every tool case is that the worker misused the tool or someone removed the guard. Michigan measures misuse and alteration by what was reasonably foreseeable to the manufacturer, and whether a particular use or change was foreseeable is decided by the court as a legal question. Guards that are routinely removed in the field, and bump-firing that every framing crew knows, are realities the foreseeability analysis exists to weigh, with evidence, not assumption.

Everyone in the chain, on the right theory. Manufacturers carry the main exposure. Non-manufacturing sellers and distributors answer more narrowly, for their own failure of reasonable care, including implied warranty, or a breached express warranty. Rental companies can face negligence claims for the condition of what they delivered, the maintenance they skipped, and the inspections they signed off on, with the rental agreement defining who owed what.

Damages have statutory contours: Michigan caps noneconomic damages in product actions, with 2026 levels of $596,400 in most cases and $1,065,000 where the injury is death or permanent loss of a vital bodily function, and the caps can fall away where a defendant knew the defect and showed willful disregard. We walk clients through those numbers candidly at the start, not after months of work.

One more Michigan rule worth knowing: your employer generally cannot be sued, but in a product case the defense can ask the jury to allocate a share of fault to the employer as a nonparty, which reduces the manufacturer’s share. It is a routine defense strategy in equipment cases, and it is why the site facts still get worked up even when the target is the maker.

The Tool Is the Evidence: Preserve It

Nothing in an equipment case matters more than the failed unit, unrepaired, with its serial number, its accessories, and the pieces that broke. Employers send tools back to rental fleets; adjusters approve repairs; broken hardware goes in the dumpster the same day. Losing the unit does not always end a case; photographs, exemplars, and records can carry one, but it makes everything harder.

Practically: photograph everything where it happened, note serial and model numbers, keep the packaging or manuals if they exist, and identify where the equipment came from: purchase, rental, another contractor. Workers often cannot lawfully keep employer or rental property, which is why the real preservation work is legal: demands to every company in the chain, prohibitions on repair or disposal, documented chain of custody, and, where the case warrants, teardown by engineering experts under protocols all parties observe, nondestructive testing first. Where a company moves to destroy or alter evidence anyway, courts can be asked to stop it.

Comp runs alongside all of it: medical care and wage-loss benefits, generally 80 percent of after-tax wages up to $1,201 per week for 2026 injuries, regardless of fault, with the carrier’s reimbursement rights and future-benefit credit handled inside any recovery. Fatal failures support wrongful death claims through the estate; see our workplace wrongful death page.

Frequently Asked Questions

• The nail gun fired twice and put a nail in my hand. Is that a case or just how nail guns are? It may be a case. Double-fires and bump-trigger injuries sit at the center of decades of nail gun litigation, and sequential-trigger alternatives have existed for most of that history, though the analysis ties to your specific model and when it was made. The answers live in the trigger design and the gun itself, so keep it exactly as it is and let us look.
• My harness was inspected and still failed. Who answers for that? Potentially the manufacturer of the harness or lanyard, a component maker, the supplier, and any rental company that furnished it. A component that fails within its rated use raises hard questions for the maker, though the investigation also has to rule out anchorage, compatibility, and wear issues the defense will raise. The inspection record can help by showing the gear passed review, and everything turns on preserving and examining the equipment.
• The guard was off the saw when I got hurt. Doesn’t that end it? Not automatically. Michigan asks whether the alteration was reasonably foreseeable to the manufacturer, and guards that are routinely removed in the field, or designed so the tool invites removal, are a known engineering problem the case can prove up. Your own share of fault, if any, reduces the recovery, and above 50 percent it cuts off non-economic damages, so the guard’s history matters. The saw, with and without its guard, tells the story.
• The lift belonged to a rental company. Is that a product case? It can be both a product case and a negligence case, depending on why the lift failed. The manufacturer answers under product law for design and manufacturing defects; the rental company answers in negligence for the condition it delivered, maintenance it skipped, and inspections it signed off on. A failure caused purely by skipped maintenance may leave only the rental claim. Rental agreements assign these duties in writing, which is why we obtain them early.
• The tool that hurt me was fifteen years old. Do I still have a claim? Possibly. Age does not end a Michigan product claim, though a product in use ten years or more requires proving the case without any evidentiary presumption, and the design is judged against its manufacture date. Old equipment can also point to whoever kept renting, supplying, or maintaining a machine well past the manufacturer’s service criteria, a negligence question that runs on its own track.
