Repair Shop Injuries & Customer Slip and Falls

When a customer or employee is injured in a repair facility, the case turns on whether the shop met industry safety standards. I evaluate customer access policies, walkway and floor conditions, fluid spill control, lift and equipment safety, signage, and staff procedures against OSHA guidelines and accepted industry practice. With 35+ years working in shops and teaching shop safety at the college level, I know what a properly run facility looks like — and can document precisely where one fell short, or show that it didn’t.

Commercial truck brake cases demand an expert who has actually diagnosed, repaired, and taught these systems. I investigate the full air brake system — compressor, valves, chambers, slack adjusters, linings, and air supply — along with maintenance records, DOT inspection history, and driver reports, to determine whether a failure came from a defect, neglected maintenance, improper repair, or operator factors.

Tire Failure Analysis

Tread separations, blowouts, and wheel-off incidents frequently originate in the service bay, not the factory. I examine tire failures through the lens of maintenance and repair practice: mounting and installation procedures, torque, tire age and condition at last service, inflation history, rotation, and whether inspections should have c

Tread separations, blowouts, and wheel-off incidents frequently originate in the service bay, not the factory. I examine tire failures through the lens of maintenance and repair practice: mounting and installation procedures, torque, tire age and condition at last service, inflation history, rotation, and whether inspections should have caught the problem. For questions of tire design or compound engineering, I’ll tell you plainly when a tire design specialist is the right call — and my analysis pairs cleanly with theirs.

Improper Repair Procedures & Service Negligence

Improper Repair Procedures & Service Negligence

Improper Repair Procedures & Service Negligence

Was the repair done to OEM specification? I compare the work performed against factory service information, technical service bulletins, and industry standards, then trace whether the deviation caused the failure. Repair orders, parts invoices, and technician notes usually tell a story — I know how to read it, because I’ve written thousands of them.
