Which label indicator alerts you to wearing a respirator?

• A. A stated respirator requirement or an acute inhalation hazard on the PPE section of the label.
• B. A rainfast indicator.
• C. A symbol indicating high volatility.
• D. A note about storage temperature.

Answer: (A)

Pesticide labels tell you exactly what protective gear to wear, and any respirator requirement will be stated in the PPE section or noted as an acute inhalation hazard. When the label lists a respirator requirement or warns of an acute inhalation hazard, that information is signaling you must use a respirator during handling or application. Other label notes, like a rainfast indicator, a symbol for high volatility, or storage temperature, don’t indicate respiratory protection: rainfast relates to drying after rain, volatility to vapor risk, and storage temperature to how the product should be stored. So the indicator that tells you to wear a respirator is the explicit respirator requirement or acute inhalation hazard in the PPE section.
