Which of the following best describes gloves policy between samples?

• A. Reuse gloves between samples
• B. Wipe gloves with sanitizer between samples
• C. Keep wearing gloves between samples
• D. Use new gloves for each sample

Answer: (D)

The key idea is preventing cross-contamination and preserving sample integrity. In lead clearance work, changing gloves between samples is essential because it creates a fresh barrier that won’t carry dust or residues from one sample to the next. Using new gloves for each sample ensures that any lead dust or contaminants picked up from one sample aren’t transferred to another, which protects both the accuracy of the results and the worker.

Reusing gloves between samples can move contaminants from one sample to another, compromising results. Wiping gloves with sanitizer between samples isn’t reliable—gloves can still harbor particulates or micro-dust, and sanitizers don’t guarantee complete decontamination. Keeping the same gloves on between samples also risks cross-contamination. In short, using new gloves for each sample provides the safest and most accurate standard for sample collection.
