Before handling pesticides, what is an important preliminary action an applicator should always take?

Reviewing pesticide labels closely is a critical preliminary action for an applicator to take before handling any pesticides. The pesticide label contains essential information about the product, including safe handling instructions, application rates, personal protective equipment (PPE) requirements, environmental hazards, and first aid measures in case of exposure.

By thoroughly understanding the label instructions, the applicator ensures compliance with legal regulations and safety protocols, ultimately protecting their health and the environment. This step provides detailed guidance on how to effectively and safely use the pesticide, preventing potential accidents or misuse.

The other options, while they can be useful, do not provide the foundational knowledge that reviewing the pesticide label does. Preparing a storage area or making a checklist may help with organization and efficiency, but they do not address the immediate safety and operational procedures that are necessary when handling chemical substances. Speaking with colleagues can provide additional insights or support, but it cannot substitute the crucial information found on the pesticide label that is specific to the application being performed.
