What should be done to protect against pesticide inhalation?

Wearing a proper respirator is essential for protecting against pesticide inhalation because respirators are specifically designed to filter out harmful particles and gases from the air. They create a seal around the face, which helps ensure that contaminated air does not enter the respiratory system. Depending on the type of pesticide being applied and its formulation, certain respirators are rated to provide adequate protection against specific chemical concentrations and types, including particulate filters for solid pesticides and chemical cartridges for gases and vapors.

In contrast, a simple surgical mask is primarily designed to block respiratory droplets and is not effective at filtering out the small particles or toxic vapors found in many pesticides. Covering the mouth with a bandana may provide minimal protection but does not create a reliable seal nor offer sufficient filtration against chemicals. Staying indoors would limit exposure to pesticide application, but it is not a practical solution for someone who needs to apply pesticides outdoors. Hence, the use of a proper respirator is the most effective measure for safe pesticide handling and application.
