Which of the following on the treatment floor poses an environmental risk?

• A. Unlocked chemical bottle
• B. Waste bag inside a closed cart labeled biohazard
• C. Sterile gloves worn while interacting with a patient
• D. Open food left at the workstation

Answer: (A)

Unsecured chemical containers create the most environmental risk because a spill can quickly spread contaminants across floors, into drains, and onto surfaces, potentially reaching the water supply and posing exposure risks to staff, patients, and the environment. An unlocked bottle is easy to tip or knock over, and it increases the chance of fumes, splashes, or leaks that require cleanup and can cause lasting contamination. The safe practice is to keep chemicals capped, stored in a locked cabinet or designated area, and to follow spill-cleanup procedures using proper containment and labeling.

The other scenarios are less about environmental hazard in this context: a waste bag inside a closed cart labeled biohazard is contained and designed to prevent release of infectious material; sterile gloves are PPE that, when disposed of properly, do not represent an environmental spill risk; open food may create sanitation issues but does not involve hazardous chemical contamination.
