Which of the following is NOT a type of area that commonly involves chemical use or storage?

The correct answer is that residential living rooms are not typically associated with the common use or storage of chemicals. In general, living rooms are spaces designed for relaxation and socialization, and they usually do not contain hazardous materials or chemicals commonly found in other environments, such as janitor's closets, high-volume copy rooms, and art rooms.

Janitor's closets often contain cleaning supplies that include various chemicals for maintaining hygiene and cleanliness in a building. High-volume copy rooms may utilize inks, toners, and solvents that are essential for printing and copying tasks. Similarly, art rooms often have paint, solvents, and other materials that involve chemicals needed for artistic activities.

Residential living rooms, however, generally prioritize comfort and leisure, making them less likely to pose any chemical-related risks associated with the other listed areas. This distinction underscores the focus on safety in environments that are specifically designed for activities that may involve hazardous substances.
