Machine Guarding Expert Witnesses

Start Machine Guarding Expert Search

Intended to protect humans from personal injury, machine guarding refers to the safety features on manufacturing or engineering equipment. A machine guarding expert witness is typically a licensed professional engineer or certified safety professional with a background and expertise in electrical engineering, mechanical engineering, product design, and/or industrial design. An expert witness in machine safety and machine guarding should also be familiar with the hazards addressed in OSHA standards and OSHA regulations. The chosen expert is often a member of an industry or technical organization, such as the American Society of Mechanical Engineers (ASME), IEEE, or the National Tooling & Machining Association (NTMA).

Frequently, matters requiring machine guarding expert witness services involve intellectual property, such as patent infringement litigation, inter partes review or trade secret disputes. A forensic expert can reverse engineer components to prove (or disprove) intellectual property infringement or theft. A machine guarding expert could also be called in to consult on technical issues, which could require forensic engineering work. A machine guarding expert witness might also provide testimony in a torts matter like a personal injury case as a result of an accident, or a product liability case involving the failure analysis involving the machine safety of industrial equipment or construction equipment.

Litigation support by a machine guarding expert witness could include reverse engineering, expert report, expert opinion, and expert testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a mechanical engineer with prior expert witness experience. An engineering expert witness needs to not only have technical expertise, an expert witness must possess the ability to explain technology to lay people. In addition, clients may seek an mechanical engineering expert witness for pre-litigation consulting work.

Whether the case involves farm machinery, industrial machinery, construction safety, machine safeguarding, machine tools, factory automation systems, robots, or anything in between, Cahn Litigation Services has the experience required to turn an expert witness search around quickly. We provide the right balance of expertise and testimony to support each unique project.
