Public storage expert witnesses may write reports and testify on mini-warehouses, storage warehouses, and self storage units. In Going Your Separate Ways: Evicting the Trouble-Maker Tenant, attorney William D. Farrar writes descirbes the cost in having a trouble making tenant:

As hard as tenants are to get in the first place, we truly dislike having to ask one to leave. However, the “cost” in having a trouble-making tenant stay will far exceed the rent they are paying. The “cost” in other tenants being unhappy, and leaving, negative publicity, and management time dealing with ongoing problems will add up! After all, you can quantify your loss from an empty unit- not so the problem tenant. Sometimes an empty unit is better than one with rented problems!

Vinyl products expert witnesses may write reports on engineered composites, polymers, PVC, and related topics. In Health and safety – Phthalate plasticizers, PAS Systems International offers this information:

Many vinyl products contain additional chemicals to change the chemical consistency of the product. Some of these additional chemicals called additives can leach out of vinyl products. Plasticizers that must be added to make PVC flexible have been additives of particular concern.

Because soft PVC toys have been made for babies for years, there are concerns that these additives leach out of soft toys into the mouths of the children chewing on them. Phthalates mimic human hormones and also affect various life forms including fish and invertebrates adversely. Additionally, adult sex toys have been demonstrated to contain high concentrations of the additives.21 In January 2006, the European Union placed a ban on six types of phthalate softeners, including DEHP (diethylhexyl phthalate), used in toys. In the U.S. most companies have voluntarily stopped manufacturing PVC toys with DEHP.

In PRESERVE THE PHYSICAL EVIDENCE!, electrical equipment failure expert witness Roger L. Boyell, writes:

As soon as you believe a legal action might be initiated, take pains to preserve whatever physical evidence may be relevant. Send in an investigator, take many photographs, expedite the discovery process.

Any delay allows potential evidence to be altered or disguised, as in the following real-world examples.

Insurance coverage expert witnesses may write reports and testify on insurance customs, insurance practices, liability policies, and more. Here, Insurance.com writes on liabilities issues when hosting a a party:

Whether you’re driving to the big game, watching it in a bar or hosting a party, follow these tips to keep from dropping the ball on your insurance coverage. A big… issue can be liability if guests hurt themselves on your property or, worse, drink and drive. State laws vary, but even “states that don’t impose liability in general can impose it if the host serves alcohol to a minor,” says Kenneth Berman, an attorney with Berman, Sobin & Gross, LLP in Gaithersburg, Md. “Everyone should go into this knowing that they can be held responsible if a guest gets hurt or hurts someone else,” he says.

According to Lisa Lobo, vice president and consumer insurance expert at The Hartford, “Liability insurance is part of every homeowners policy and would cover up to your limit, usually about $100,000 if someone slips and falls on an icy sidewalk or drowns in your hot tub. But liability insurance may not be enough. We recommend a personal umbrella policy to cover all of your assets and net worth in case of a lawsuit.” Umbrella insurance policies offer additional liability coverage of $1 million or more and usually cost $200 or $300 annually.

Process service expert witnesses may opine regarding the process server’s work product. The National Association of Professional Process Servers has established the Standards, Best Practices and The Policy Manual for professional process servers:

PROOFS AND AFFIDAVITS OF SERVICE

Engineered composites expert witnesses may opine on aerospace components, household products, sports equipment, and more. This week the Little League issued a moratorium on composite bats, which on many fields have replaced aluminum (and wood) as the preferred equipment for young players. “A ball could go farther and harder and some of these kids are small so it’s a safety concern that we’re looking at,” said Greg Jones, a Palma Ceia Little League board member.

The bats are prized for their performance factor. Fans say the ball comes off the bat faster and goes farther, giving hitters more power to hit home runs and boost team scores. “It’s carbon fiber, but there’s also a resin in it that expands and it allows the barrel of the bat to flex, which gives it more pop,” said Paul Borgeson, who has been selling the popular bats at Play it Again Sports.

Truck maintenance expert witnesses may write reports and testify regarding federal motor carrier safety regulations, qualifications of truck drivers, federal motor vehicle safety standards, and truck maintenance, among other topics. In Maintenance Musts, Steve Sturgess, Executive Editor truckinginfo.com, writes:

Vehicle maintenance is one of the top areas where fleets are at risk under the Federal Motor Carrier Safety Administration’s new CSA 2010 program.

Carrier safety risk management firm Rair released a report comparing the safety methodology under the new Comprehensive Safety Analysis program to the older SafeStat records of more than 64,000 fleets. It showed fleets are most at risk from deficiencies in fatigued driving (hours of service violations), but next is vehicle maintenance.

In Are You Waiting Too Long To Hire An Expert?, construction site expert witness William Gulya, Jr., President & CEO, Middlesex Trenching Company, writes:

Another detrimental aspect of retaining the expert too late is retaining him or her after the discovery period is closed. A qualified expert can tell you exactly where to look for potentially damaging evidence on your adversary, which may support your position. What may not seem important or relevant may in fact be the smoking gun you are looking for. Attorneys know the law and are experts in the law. They often do not know the intricacies, nuances, and particulars of specific industries such as heavy or site-work construction methods, means and industry standards that apply to them.

An expert who knows the industry and the acronyms, lingo, and generic terms associated with that industry can be a valuable asset in preparing deposition questions for your adversary. Taking your expert to adversary depositions can be extremely helpful. Many times, the person being deposed will say something that to the attorney may sound logical and reasonable; however, the answer may have contained industry terminology that camouflages the truth. An expert who is thoroughly familiar with the vernacular of the trade can recommend questions exposing restrictive or misleading language. The ability to query cautiously worded answers can change the impression intended to be conveyed by your adversary.

Pesticide products expert witnesses may write reports and testify on pesticide contamination, insecticides, and pesticide products. In The Globally Harmonized System of Classification and Labeling of Chemicals the EPA Office of Pesticide Programs describes GHS:

The GHS establishes classification criteria for physical, health and environmental hazards, along with associated hazard communication elements, notably pictograms, signal words, and hazard statements for use on labels. It is based on harmonizing major existing systems for classifying and labeling of chemicals in transport and in the workplace, in pesticides, and in consumer products. A key guiding principle of the GHS harmonization effort was that harmonization should be accomplished without lowering the level of protection afforded by existing systems. It was also acknowledged that changes in all systems would be required to achieve a single, globally harmonized system.

Liability policies expert witnesses may testify regarding insurance loss claims, insurance policy coverage, liability policies, and related topics. In The Insurer’s Duty to Defend: A Quick Analysis, attorney Thomas H. Veitch, partner with the law firm of Langley & Banack, Inc. in San Antonio, writes:

The issue whether a duty to defend exists is a question of law.

The insured has the initial burden to establish that its claim falls within the scope of coverage provided by the insurance policy.
