Preserve the Exact Tool and Every Component Used With It
You can begin by identifying the tool by brand, model, serial number, labels, and the accessory that was installed when you were injured. Keep the blade, bit, battery, charger, fastener, guard, handle, attachment, or replacement part if you can do so safely. Photograph broken pieces, deformation, burn marks, missing components, and the work area without altering the tool to make the failure easier to see.
You should not test or repair the tool after the incident. A damaged battery, cutting component, electrical system, or fastening mechanism can create a second hazard, and testing can also change the condition that needs to be examined. Keep the receipt, packaging, manual, warning labels, service history, and warranty communications that identify how the product was sold and maintained.
Distinguish a Product Issue From Misuse, Wear, Service, or Modification
A product claim may involve a design defect, manufacturing defect, or warning issue depending on the facts. The evidence can also show wear, improper service, modification, use of an incompatible accessory, or another explanation. You do not need to decide the cause yourself. Preserve the product and history so competing explanations can be evaluated from the physical evidence.
A recall or safety notice can be relevant, but it does not automatically decide your claim. Keep only the recall information you can reliably connect to the product. If the tool was modified, repaired, or serviced before the injury, preserve who performed the work, what parts were changed, and when the work occurred.
Connect the Tool Failure to the Medical and Occupational Harm
Tell your medical providers exactly how the tool injured you. A blade can sever tendons and nerves, a kickback can fracture a wrist, a fastener can penetrate tissue, and an electrical failure can cause burns or a fall. Keep operative reports, imaging, therapy notes, nerve studies, eye treatment, prosthetic care, and restrictions so the physical consequences remain clearly documented.
Your work loss can be substantial when your occupation depends on dexterity, grip, vision, strength, or repetitive tool use. Keep wage records, job descriptions, overtime history, certifications, and medical restrictions. If you cannot return to the same trade or duties, document which tasks you can no longer perform and how your earning ability changed.
Protect the Product Evidence When Other Parties Want the Tool
An employer, retailer, manufacturer, insurer, or service company may ask to inspect, replace, or take the tool after an injury. Keep written records of any transfer and preserve photographs, serial numbers, accessories, packaging, and documents before the product leaves your control. If safe storage requires professional handling, prioritize safety while maintaining a clear record of where the tool went.
If the injury causes amputation, permanent disability, or death, the tool and its components can remain important while your medical or family losses continue developing. Preserve the product evidence, medical history, employment records, and family documents while allowing the technical investigation to determine whether a defect, service problem, modification, or other factor caused the harm.
