Final answer:
Single-use gloves must be replaced when contaminated or torn, and between tasks. In continuous tasks, they should still be replaced periodically, with hand hygiene practiced after removal.
Step-by-step explanation:
A pair of single-use gloves should be changed whenever they become contaminated, torn, or when starting a new task. When an employee is working continuously on the same task, the gloves should still be replaced periodically to ensure safety and hygiene, particularly in a healthcare setting where cross-contamination is a concern. After removing gloves, it is essential to perform hand hygiene. For example, health-care workers must wash their hands thoroughly after the removal of gloves and between patient contacts. In situations involving hazardous materials or cleaning up after a procedure, gloves may need to be changed more frequently to avoid spreading contaminants.
