In which scenario must employers maintain employee-handler use records?

Employers are required to maintain employee-handler use records particularly for organophosphate pesticides that are labeled with cautionary indications like "DANGER" or "WARNING." This is primarily due to the heightened toxicity associated with these chemicals, which can pose significant risks to health and safety.

The rationale behind maintaining records for these pesticides is to ensure that there is a transparent and traceable account of their use, which is essential for monitoring exposure and ensuring compliance with safety regulations. By documenting employee handling of such substances, employers can take appropriate actions in the event of an incident or health concern, as well as fulfill regulatory obligations regarding pesticide safety. This practice helps protect both the workers who handle the pesticides and the broader environmental health.

The requirement typically does not extend to all pesticides or specific labels like “CAUTION” or usage indoors, as these categories do not have the same level of regulatory scrutiny or health implications as do organophosphate pesticides that bear more severe warnings.
