Once the StoneLite® panels (stone and porcelain) are manufactured and installed, minimal to no exposure is expected during the normal, daily use of the product. Many of the listed hazards are only present during the manufacturing process.

Natural stone is a geologically derived material that constitutes a significant portion of stone panels. Under HPDC's special conditions policy, hazard screening is not applicable to natural stone, as it is considered to have inherently minimal human health impacts in its finished form. Being a naturally occurring material, it does not undergo significant chemical transformations during processing, and any trace elements present are typically bound within its mineral structure, limiting potential exposure risks.

In the case of porcelain panels, the porcelain mass also constitutes a significant portion of the material composition. While frits used in porcelain may exhibit human health hazards during screening, they undergo a high-temperature vitrification process that renders them insoluble and chemically stable. In the final product, any hazardous raw materials are rendered inert, minimizing human health risks during use. Additionally, porcelain’s low porosity and resistance to degradation further reduce the likelihood of any chemical release over time.

In the composition of both types of StoneLite® panels, potential chemical exposure hazards are primarily associated with the manufacturing stage. Certain ingredients in resins, epoxies, and hardeners may present health warnings in their raw form. However, once these materials are fully cured and the panels are installed, they undergo chemical changes that stabilize them. As a result, under normal use conditions, the finished product is not expected to pose health hazards to customers.
