When consulting as an expert witness, having certifications can assist in establishing your credibility and qualifications. If you’ve perused the Curriculum Vitaes of the experts at The Warren Group, Inc., you may have seen some of these letters trailing after our names. What do they mean and what organizations grant them? The following is a sampling of some of the certifications our experts have acquired:
The Professional Engineer (PE) is a designation awarded by a state licensing board after the engineer passes a discipline-specific exam and proves appropriate work experience and references. This designation is legally recognized and grants the engineer specific rights and responsibilities, especially regarding public safety and the approval of engineering work.
The Certified Fire and Explosion Investigator (CFEI) is a designation awarded by the National Association of Fire Investigators (NAFI). This credential demonstrates a professional’s ability to determine the origin and cause of fires and explosions through methodical investigation techniques. CFEIs often serve as expert witnesses in insurance subrogation litigation, where scientific accuracy and adherence to NFPA 921 standards are essential.
The ACTAR Certification is a professional credential that recognizes individuals who have demonstrated a high level of expertise in the field of traffic accident reconstruction. This certification is designated by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR), an independent, non-profit organization. ACTAR was established to maintain standards of competency and ethical conduct among professionals involved in the analysis and reconstruction of motor vehicle collisions. To earn the certification, candidates must meet specific educational and experience requirements and pass a comprehensive written examination. The credential is widely respected within the forensic and law enforcement communities and is often used to establish credibility in legal and investigative settings.
The Certified Machinery Safety Expert (CMSE®) is a designation awarded by the TUV Nord organization (a German organization that works to validate the safety of products and services of all kinds to protect humans, material assets and the environment against hazards). It signifies advanced competence in understanding and applying machinery safety standards, regulations, and best practices. Their primary role is to provide technical insight into whether machinery safety standards and regulations—such as those outlined by OSHA, ANSI, ISO, or EN—were properly followed. Drawing on their specialized training and certification, a CMSE can assess the design, operation, and maintenance of machinery involved in an incident, determining if appropriate risk assessments were conducted and if safeguarding measures were adequate.
The Certified Electrical Safety Compliance Professional (CESCP) credential, offered by the National Fire Protection Association (NFPA), emphasizes electrical safety in the workplace. CESCP-certified individuals are experts in compliance with NFPA 70E standards and are often involved in litigation related to electrical injuries, arc flash incidents, or OSHA violations. Their testimony can help clarify whether industry-best practices were followed and if electrical systems posed unnecessary risks.
Certified Playground Safety Inspector (CPSI) is a certification granted by the National Recreation and Park Association (NRPA). CPSIs are trained to assess playground equipment and environments for safety hazards in accordance with national standards. They frequently testify in personal injury cases involving children, helping courts determine if a playground was properly designed, installed, or maintained.
The Certified XL Tribologist (CXLT) is a niche certification focused on slip and fall prevention, particularly through walkway surface traction testing. Awarded by the Excel Tribometers company, this credential indicates proficiency in using the English XL Variable Incidence Tribometer to measure coefficient of friction. CXLT-certified experts are often retained in premises liability cases to evaluate flooring surfaces and determine whether they contributed to slip and fall incidents.
Lastly, the FenestrationMaster® Professional Certification (FMPC) is awarded by the Fenestration and Glazing Industry Alliance (FGIA) and signifies advanced knowledge of the fenestration industry, including performance standards, products and materials, test methods and code requirements. This credential is crucial in construction defect litigation, particularly when disputes involve water intrusion, thermal performance, or installation standards.
Each of these certifications strengthens an expert witness’s authority in court by showing that their opinions are rooted in established training, rigorous testing, and industry standards. For attorneys and litigants, selecting an expert with the right certification can be instrumental in establishing credibility and achieving favorable outcomes in complex technical cases.

In the first blog in this series, we discussed the story behind the CE mark, the Machinery Directive, and the associated requirements regarding the design, production, and sale of machinery bearing the mark. The second blog discussed a cornerstone of safer machine design, the risk assessment. This installment will discuss another crucial piece of the safety puzzle, machine guard design. Read More
In the previous blog (Part One) we discussed the backstory behind the two stylized letters CE and what it means to the design of machinery bearing the mark. We outlined some of the requirements of the “Machinery Directive” (MD) which include what are known as “Essential Health and Safety Requirements.” The Essential Health and Safety Requirements incorporate an iterative risk reduction process during design that takes into account Read More
Ammonia is a compound consisting of one nitrogen atom and three hydrogen atoms and is denoted by the formula NH3. Its boiling point is -28°F at atmospheric pressure, so unless it is under pressure, it is gaseous at room temperatures. Therefore, pure ammonia is typically stored under pressure in a liquid form. Household ammonia is only 5-10% NH3, the remaining 90-95% is water. Ammonia is extremely soluble in water. It is often depicted like this: Read More
An unfortunate and tragic case that we investigated involved a commercial “rollback” recovery truck that was being used to transport a four-wheel drive diesel pickup. The diesel pickup was not in running order with its’ engine in the bed of the truck. Consequently, a commercial towing company was hired by the truck owner to transport the truck. In the process of loading the truck onto the rollback, the truck came uncoupled from the winch and cable system. The truck then rolled down the inclined bed of the rollback, running over and killing a bystander. Read More
One of my more interesting calls and subsequent forensic investigations was regarding water accumulating inside of 2X4 fluorescent light fixtures in a suspended ceiling of a secondary school in South Carolina.
The client called and indicated that the metal chassis of the lights were sweating and generating enough water to accumulate on the diffuser lens of the lights. Obviously, an on-site investigation was in order! Read More
The Occupational Health and Safety Administration (OSHA) “Top 10 for 2018” violations once again have Machine Safeguarding earning a position on the list. Machine safeguarding was the 9th most cited standard as noted in the list below:
A worker was injured while testing gas springs similar to the type that hold the hatchback of an SUV open. The hazard that injured the worker was an unguarded shear point. The tester contained a mounting plate that was raised and lowered by a pneumatic cylinder.
The pneumatic cylinder lowered the mounting plate while the worker’s fingers were in the hazardous, unguarded shear point. Read More
A mini-excavator at a job site developed a leak at a hydraulic fitting at the base of the cylinder that raises and lowers the boom. A subcontractor foreman at the site raised the boom to search for the leak. The foreman found and attempted to tighten the leaking fitting. When he did, the fitting separated from the base of the cylinder, releasing the hydraulic pressure that held the boom aloft. The boom fell and the bucket struck a nearby superintendent for the general contractor.
