Water-based varnishes and lacquers, including those that incorporate polyurethane and acrylic resins, are generally deemed safer than solvent-based alternatives, benefiting both users and the environment. They emit fewer volatile organic compounds (VOCs), among other advantages. Nonetheless, this does not imply that there are no associated risks. Potential concerns regarding these products encompass their toxicity, potential allergic reactions, and environmental impact. 

To mitigate these risks, it is advisable to thoroughly review the product's safety data sheets, adhere to the manufacturer's instructions concerning usage and disposal, and employ suitable protective gear in a well-ventilated area. 

Additionally, it is worth noting that regulations pertaining to varnishes and other wood finishing products vary across different countries. Numerous countries enforce regulations that mandate manufacturers to reduce VOC levels and other potentially hazardous substances within their offerings. Canada, for instance, imposes restrictions on the maximum permissible VOC content in such products.
