True or False: A respirator is unnecessary when mixing soluble or wettable powders.

  1. True

  2. False

  3. Not applicable

  4. I don't know

The correct answer is: False

The statement is false because wearing a respirator is essential when handling soluble or wettable powders. These types of pesticide formulations can create fine dust or aerosolized particles during the mixing process, which can be inhaled. Inhalation of these particles can pose serious health risks, including respiratory issues and other systemic effects, depending on the toxicity of the pesticide being mixed. Therefore, personal protective equipment, including a respirator, is crucial to ensure safety and minimize exposure to harmful chemicals. Ignoring this necessity would not align with best practices in pesticide safety and handling.
