Which exposure pattern is potentially harmful to an applicator?

• A. Single exposure
• B. Several exposures over time
• C. No exposure
• D. Exposure only in winter

Answer: (B)

Repeated, cumulative contact with a chemical is the pattern most likely to be harmful. Each exposure adds to the amount already in the body, and between events there’s limited time to metabolize or eliminate it. Over time, this buildup—the total body burden—can lead to more pronounced health effects than a single exposure would cause, even if individual exposures seem small. That’s why several exposures over time are considered potentially harmful for an applicator. A single exposure might cause an acute effect if the dose is high, no exposure carries no risk, and exposure only in winter reduces opportunities for exposure overall (though it isn’t a guarantee of safety).
