Are quartz composite countertops dangerous?

Quartz composite kitchen countertops are generally safe for household use, but there are some health risks associated with their production and processing.

Quartz composite contains a high percentage of crystalline silica (silicon dioxide), often in excess of 90%. During the production, cutting and machining of quartz composite countertops, fine silicon dust is released. Inhalation of this dust can lead to serious lung diseases, such as silicosis, chronic obstructive pulmonary disease (COPD) and lung cancer. These risks primarily apply to workers in stone working and manufacturing, not to consumers who use the countertops in their homes.

Manufacturers and workshops should take strict safety precautions to minimize exposure to silicon dust. This includes the use of wet working methods, exhaust systems and personal protective equipment (such as respirators).

For consumers who have quartz composite countertops in their homes, there are no immediate health risks once the countertops are installed. The risks associated with silicon dust are specifically related to the processing of the material, not to its use in a domestic environment.

Quartz composite countertops are safe for domestic use. The health hazards associated with this material are primarily related to the manufacturing and processing processes. Industrial workers must be adequately protected by safety measures to avoid exposure to hazardous silicon dust.
