For which pest control operation is a resistance category 'D' glove requirement most typical?

The resistance category 'D' glove requirement is most typically associated with pesticide application due to the nature of the chemicals involved. Pesticides can pose significant health risks to applicators due to their potential toxicity and the way they interact with human skin. The gloves categorized under resistance 'D' are designed to provide superior chemical resistance, ensuring that they can withstand prolonged contact with pesticides without allowing them to permeate or compromise the integrity of the glove.

By requiring such specific protective gear, the standard seeks to minimize the risk of dermal absorption of hazardous substances that may lead to acute or chronic health issues. This is especially important given that pesticides can vary widely in their formulation and severity, thus necessitating a careful selection of personal protective equipment (PPE) to ensure safety during application.

The other options, such as liquid fertilizer application, herbicide spraying, and soil amendment distribution, generally involve less toxic substances that may not require the same level of protective measures, thereby making resistance category 'D' gloves less common or necessary in those practices. This distinction highlights the importance of understanding the specific hazards associated with different pest control operations to ensure appropriate safety protocols are followed.
