Modular Cabinet Systems Retail Store Fixtures: Injuries from Improper Installation

By: Michael Panish

I have been the retained expert witness by both the plaintiff and defendant to determine the causes of a variety of significant injuries that have happened as a result of improper cabinet and millwork installation practices. In most claims, if product abuse or deferred condition was not the reason for the injury, poor installation practices that have omitted required hardware was to blame. Architectural millwork injuries have occurred repeatedly in shopping centers and malls, hotels, hospitals, airports, and offices throughout the country. Casinos and restaurants are also routinely the location of significant cabinetry related failures leading to serious injuries. Many offices and industrial buildings that utilize modular furniture have had employees injured by improper or completely unattached components. In my other articles, improperly attached architectural millwork has been discussed. Heavy mirrors and headwalls have fallen upon hotel guests while they were asleep in bed. Generally, these failures occur due to lack of appropriate fasteners, missed structural connections, or product tampering.

Mechanical Fasteners

By: Michael Panish

Mechanical fasteners, when properly used as recommended by the manufacturer, almost always assure safe and secure attachment of a fastened product. In commercial and residential applications, injuries resulting from mechanical attachment failures have often been attributed to inappropriate usage of products, improper installation procedures, or the failure of a poorly manufactured fastening product. When a product becomes disconnected from its point of attachment, serious personal injury can result.

Cabinetry & Millwork: Defective Design or Defective Workmanship? Who is Responsible?

By: Michael Panish

My job as a cabinetry and millwork expert witness is to inspect and evaluate casework, cabinetry, or millwork that may have either failed or may be deficient in some way. Many of the past cases where I have been designated as the cabinetry and millwork expert witness have involved analyzing products that no longer exist because they have either been replaced or destroyed. What is available for review is often in the form of architectural elevations (renderings), photographs of the damaged cabinetry, or shop drawings and samples of the materials that were used. Generally, there is a question as to what entity is responsible for the monetary loss sustained. The usual course of action by attorneys is to sue all parties in the chain of events, from design through installation.

Contractor Fraud: Beware of Unscrupulous Contractors

By: Michael Panish

Most of the misunderstandings pertaining to contractor and homeowner relationships occur as a result of unclear or wrongly interpreted construction contracts. Upon entering into a building contract, the enthusiasm for starting the proposed work often creates a kind of glazing over or dulling of the senses on the part of the homeowner. Many times questionable terms and arrangements for payment scheduling are accepted or unknowingly agreed to as the homeowner's urgent desire to start work overshadows common sense. Often, the lowest priced contractor seduces the homeowner with promises of more value for the money.

M. O. A. T. A New Approach to School Security

By: Michael Panish

The need to have increased security to public venues such as airports, schools, religious facilities, day care centers, shopping centers, and government buildings is nothing new.

Door Injuries & "The Eggshell Plaintiff"

By: Michael Panish

Every good attorney needs to consider the validity of every potential claim. As the most frequently retained door expert witness, working for both Plaintiff and Defense evenly, I have been retained on door injury and wrongful death claims that were not caused by malfunctioning doors or door hardware. As discovery has often shown, people in poor physical or mental condition who are left unattended or unassisted while moving through properly functioning doorways are often the genesis of their own injuries. All commercial venues have the responsibility to maintain their facilities to industry wide standards, seek proper routine maintenance, and provide daily inspections of their door systems. However, it is difficult to provide safe passage to every patron of their facilities when some of those patrons may include persons requiring diligent physical supervision, special assistance walking, or have special needs due to disease, mental incapacity, or other unknown infirmities.

Garage Doors: A Brief Tutorial on Garage Door Safety & Installation

By: Michael Panish

As a door expert, I am called upon many times a year to evaluate garage door injuries. In my professional career as a general contractor and door & hardware contractor, I have installed many different types of garage doors. I have been involved with roll up doors, both for commercial warehouse applications and automotive repair facilities that allow the passage of a motor vehicle. I have installed and serviced life safety/fire drop doors typically seen in hospitals, pharmacies, labs, shopping centers and other commercial venues. I have placed sectional doors in apartment buildings, single family homes and condominiums. My company has custom built many types of garage enclosures that have had special cosmetic concealed purposes for themed attractions. Working on historic buildings has given me the opportunity to work on sliding barn type doors, hinged parting doors and old carriage style swinging doors. I have removed and replaced the older style, overhead vintage single panel pivoting hinged garage door from commercial and residential locations, and have installed a variety of newer and safer products.

Concealed Door Closers

By: Michael Panish

The overhead or floor mounted concealed door closer is a very common type of door closer mechanism which is normally unseen and unnoticed. In the majority of installations, these concealed closers are used on aluminum glazed storefront doors, hollow metal stand alone, or structural framed window systems. The concealed door closer design concept was initially engineered as a self-contained product that featured a center pivot allowing a variety of door functions with no exterior arm or visible operating hardware.

Door Defects & Door Related Injury Claims

By: Michael Panish

We are all used to opening and closing doors on a daily basis. Unless you encounter a problem with the function of your doors, you probably don't give their operation and component make up much thought. I am continually contacted by attorneys seeking my advice on an injury that took place because of an improperly adjusted or malfunctioning door. In this article, I am simply discussing manually operated doors. Nothing fancy or automatic about them, the kind where you grab a lever, push a plate or bang on a bar to enter or leave a room or building. So, if you want to learn to communicate professionally and simply with your door expert or even your building manager, read on.
