What is an essential characteristic of non powdered gloves used in sampling?

Non-powdered gloves are specifically designed to reduce skin irritation which is particularly important in sampling contexts, such as lead inspection and risk assessment. The absence of powder helps minimize the risk of allergic reactions and skin problems that can arise from residues left by powdered gloves. This characteristic is crucial because inspectors and assessors need to maintain a safe and comfortable environment for themselves while handling materials that could be hazardous.

While enhancing grip, increasing thickness, and providing insulation may have their advantages in specific situations, the primary concern with non-powdered gloves in sampling is to ensure the comfort and safety of the user by reducing potential irritants. Thus, the focus on reducing irritation stands out as the essential characteristic relevant to sampling procedures.
