Pesticides expert witnesses may testify and provide reports on consumer products treated with pesticides:

The presence of microorganisms (bacteria, fungi, and viruses) in or on various items has become of increased concern to consumers. In response to these concerns, many products (e.g., cutting boards, kitchen sponges, cat litter, toothbrushes, and juvenile toys) are being treated with antimicrobial pesticides. Antimicrobial pesticides are substances or mixtures of substances used to destroy or limit the growth of microorganisms, whether bacteria, viruses, or fungi — many of which are harmful-on inanimate objects and surfaces.

Treated articles typically refers to articles or products that are treated with an antimicrobial pesticide to protect the articles or products themselves. The pesticides are usually added to the products (e.g., plastic shower curtain) during manufacture; however, they may be added after manufacture but before use of the article (e.g., incorporation of a pesticide in paint).

According to the Center for Injury Prevention and Control, motor vehicle crashes are the leading cause of death among U.S. teens, accounting for more than one in three deaths in this age group. Most teen accidents can be easily avoided. Insurance experts at CURE Auto Insurance provides the following list of tips for teens and parents to ensure teens stay safe behind the wheel.

Safe Driving Tips for Teens:

1. Put your cell phone away. According to the National Highway Traffic Safety Administration (NHTSA), nearly 6,000 people died in 2008 in crashes involving a distracted or inattentive driver, and more than half a million were injured. Statistics show that talking on the phone or texting while driving is just as dangerous as driving drunk. Next time you’re tempted to use your phone in your car, ask a passenger to send a text for you or pull off to the side of the road if it is urgent.

Sales expert witness Glen Balzer is a widely published author on distributor and representative relationships and agreements, as well as sales organizations and commissions. Here he writes on traits of successful representative agreements.

Mature suppliers and representatives do not treat each other as the junior partner in a representative partnership. When a partner is able to insert a biased clause into the agreement, it must be because the other partner has less experience in terms of drafting and negotiating representative agreements. Remember that the junior partner will ultimately learn that a biased agreement is to its disadvantage. Keep bias out of the agreement and ensure that the relative power of the supplier and representative is balanced.

In Truck/Tractor-trailer brakes and accident reconstruction, trucking expert witness
Robert Reed writes:

The importance of checking proper operation of the ABS system is that some fleets do not have in house maintenance that can diagnose and repair systems and over the road trucking companies tend to not take trucks/trailers out of service for repair for ABS light that stays on. Bulbs or fuses sometimes disappear from the dash warning light and system. Some veteran drivers remember the late 1970’s and don’t care for ABS because they think they have more skill in braking than ABS. This is not true as the new ABS systems have proven there reliability. Trucks/trailers with ABS problems will revert back to regular braking if any faults exist and the wheel or axle with a problem can skid. This can change or explain a stray skid mark that shows up at a scene. Other problems can develop with ABS with maintenance or lack thereof ABS wheel sensors, wiring, or exciter tone rings can be damaged and cause faults. Some fleets will avoid the costs as the truck still has regular brakes. Most normal stops by trucks/trailers do not involve ABS functions as ABS only releases the brake when skids/lock-up situations are detected but emergency/panic stops involving crash situations need the ABS functions to stop sooner or maneuver. If you encounter the unusual check for proper ABS functions.

In Mold, Housing and Wood, wood products experts at the Western Wood Products Association write:

Where is mold found in buildings?

The presence of molds in our everyday environment means they can grow anyplace under the proper conditions. In all cases, moisture is the essential element for mold growth in buildings. There are many potential sources for unwanted moisture in buildings. For example, improperly maintained air conditioning systems that create excessive condensation can be a breeding ground and distribution mechanism for mold particles.

In Driver Fatigue is the Number One Safety Issue in the Truck and Bus Industry, fatigue expert witness Dennis Wylie writes:

Fatigue causes cognitive impairments that affect vigilance, attention, perception, and decision making – processes that are crucial to safe driving. These objective, measurable cognitive fatigue effects can occur without any marked degree of prior physical exertion, and the driver may not be aware of these impairments. Another serious fatigue threat to safe driving is drowsiness – the tendency to fall asleep at the wheel. This is also a condition that drivers tend to underestimate (or to be totally unaware of) while it is actually happening to them. Circadian rhythm interacts powerfully with fatigue and sleep debt, and has a major impact on human error.

Driver fatigue is also partly a subjective experience (that is, one that the driver is aware of), characterized by lack of motivation, feelings of exhaustion, boredom, discomfort, and a disinclination to continue driving. These effects of fatigue can impair driving safety by impairing sustained attention and safe decision making.

Ergonomics expert witness John D. Lloyd, Ph.D., M.Erg.S., C.P.E., writes on Carpal Tunnel Syndrome (CTS):

First described by Sir James Paget in 1865, carpal tunnel syndrome (CTS) is the most common example of a nerve compression disorder. Other terms used to describe this disorder include: writer’s cramp, occupational neuritis, partial thenar atrophy, and median neuritis.

is caused by restriction of the median nerve as it passes through the carpal tunnel, an anatomic space in the wrist bound on the palmar side by the inelastic transverse carpal ligament and on the dorsal aspect by the carpal bones. The 10 structures that transverse the carpal tunnel include the four tendons of the flexor digitorum superficialis, the four tendons of the flexor digitorum profundus, the flexor pollicis longus and the median nerve.

Acoustics expert witness Angelo J. Campanella, P.E., Ph.D. FASAA describes how sound is measured:

A sound level meter (SLM) is the principal instrument for general noise measurement. The indication on a SLM (aside from weighting considerations) indicates the sound pressure, p, as a level referenced to 0.00002 Pa, calibrated on a decibel scale.

Sound Pressure Level = 20 x lg (p/0.00002) dB

Sales expert witness Glen Balzer is a widely published author on distributor and representative relationships and agreements, as well as sales organizations and commissions. Here he writes on traits of successful representative agreements.

Prepare for the future. Partnerships are born during a phase of euphoria. They develop during a phase of expansion and excitement. They mature during a long period of hard work. They unwind for a number of reasons, most of which are quite natural. Upon termination, both supplier and representative must be able to go about their own respective businesses. Spell out clearly the conditions under which either party may terminate the agreement and the responsibilities of both parties after notice of termination.

The supplier and representative must both have the ability to terminate the representative agreement for cause and convenience. Sometimes termination for cause achieves instant agreement between the parties, as in cases where the representative or supplier becomes insolvent. Getting both parties to agree that a particular cause is valid is often difficult. Gaining agreement as to which party is responsible for cause is routinely more difficult. Termination for convenience eliminates an avoidable and unnecessary argument.
