What do improperly stored janitorial supplies potentially pose?

Improperly stored janitorial supplies can pose a significant health hazard due to the materials often being toxic or hazardous in nature. These supplies can include bleach, disinfectants, and other chemicals that, if not stored correctly, can leak, spill, or create fumes that are harmful to employees and customers. In addition to the risk of chemical exposure, improperly stored supplies can lead to contamination of food preparation areas or surfaces, which can cause serious health risks.

When considering other options, while a cleanliness issue might arise if supplies are not handled properly, it does not directly address the greater health implications associated with chemical exposure. Aesthetic concerns, such as how supplies are presented, are relatively minor compared to potential health risks. Similarly, cost-saving opportunities are not relevant when it comes to the safe storage and handling of materials that directly affect the well-being of staff and customers. Thus, the most pressing concern regarding improperly stored janitorial supplies is their potential to create health hazards.
