Mold growth may occur if new flooring is installed without adequately curing and drying underlying concrete or if exposed wood flooring materials get wet and are not adequately dried before installation. Existing mold can also be accidentally disturbed during removal and repair work. Exposure to mold spores can cause health hazards to third parties. Cleanup claims and third-party claims for bodily injury and property damage may result.
Accidental spills and leaks of adhesives, sealants, solvents, and cleaners at the jobsite, location of storage, and during transportation may cause third-party exposures and cleanup. Some products are flammable and may result in a fire that spreads and releases other contained materials and produces hazardous vapors.
Typical adhesives, sealants, and caulking used for installation contain solvents and certain carcinogens, such as ammonia-based compounds, alkylated benzenes, petroleum distillates, carbon black, titanium dioxide, benzoate derivatives, silica, siloxanes, and isocyanates. Volatilization of these contaminants into a building environment can expose third parties to harm.
Engineered woods and sheathing contain adhesives for binding wood fibers and maintaining structural properties. Sawing, planing, drilling, and other abrasive manipulation of engineered woods, sheathing, and hardwood materials generate airborne particles. These can impair air quality and expose persons to inhalable particles containing toxic chemicals, including formaldehyde, urea, phenols, melamine, isocyanates, urethanes, and organic allergens. If adequate ventilation is not present, dust can be suspended in the air and, under certain conditions, become explosive. Fires involving these materials can release toxic air emissions.
Crystalline silica is one of the minerals in tile and natural stone. Construction processes performed during tile or stone flooring removal or installation include cutting, chipping, drilling, and grinding. These abrasive processes make silica respirable. Third parties can breathe in crystalline silica dust, and exposure can lead to respiratory illnesses, including lung cancer and silicosis, which in severe cases can be disabling or even fatal.
Removal of old floor tiles, carpeting, base wallboard, insulation, and other dry building materials can release dust containing many allergenic or disease-causing contaminant particles or substances, including applied pesticides, cyanides/cyanates, polycyclic aromatic hydrocarbons (PAHs), dioxins/furans, molds, drug manufacturing residues, biocides, asbestos, lead-based paint, and flame retardants. With improper containment of the workspace or improper cleanup, these particles can remain behind, enter HVAC systems, and even migrate into areas where work was not conducted, exposing property occupants.
Improper disposal of chemicals, cleaners, and solvents can lead to environmental tort liability and cleanup costs. Flooring contractors may inadvertently dispose of hazardous material improperly, such as asbestos in old flooring, which requires special disposal procedures.
Asbestos can be found in tiles and vinyl sheet flooring backing. Sanding, sawing, drilling, or tearing during repair or removal can disturb unidentified asbestos. Accidental disturbance can expose individuals to inhalable asbestos fibers that can cause serious health hazards or fatal diseases such as asbestosis, lung cancer, mesothelioma, and other cancers.
As a contractor, you can be faced with the cost to defend yourself against allegations or legal action from pollution-related events, regardless if you are at fault or not. Having the proper insurance coverage in place will help fund the expenses incurred to investigate or defend against a claim or suit and provide you with environmental claims handling expertise.
