Which type of gloves should be worn when handling wastewater samples to prevent contamination?

• A. Nitrile gloves
• B. Latex gloves
• C. Leather gloves
• D. Cotton gloves

Answer: (B)

Preventing contamination comes down to using a clean, tight barrier between your hands and the samples, along with good technique. Latex gloves provide that strong barrier and give you close, precise control, which helps you handle small sample containers without transferring microbes or particulates. When you use powder-free latex gloves, you minimize introducing any particulates into the samples, further protecting sample integrity. Remember to change gloves between samples and inspect them for tears before use to maintain a proper protective barrier.
