How is the inhalation risk described for wettable powders?

1. Low dermal hazards

2. Needs agitation

3. Inhalation risk is present

4. Non abrasive to equipment

The correct answer is: Inhalation risk is present

Wettable powders are formulations that must be mixed with water to create a solution for application. When handling these powders, especially during the mixing process, there is a potential for inhalation exposure. The fine particles present in wettable powders can become airborne, posing a risk if inhaled. This characteristic means that individuals handling or applying these materials must be aware of the inhalation hazards involved, particularly in poorly ventilated spaces or when excessive agitation is required during mixing. Adequate protective measures, such as wearing masks or ensuring proper ventilation, can help minimize inhalation risks. Understanding this risk is crucial for safety in pesticide application, as inhaling these particles can lead to respiratory issues and other health concerns. Therefore, recognizing that inhalation risk is present with wettable powders underscores the importance of using appropriate safety equipment and following best practices during handling and application.
