How often must handlers receive pesticide safety training?

Handlers must receive pesticide safety training annually to ensure they are up-to-date on the latest safety practices, regulations, and proper handling techniques. This frequency is designed to reinforce knowledge and awareness regarding potential hazards associated with pesticides, as well as to familiarize handlers with new products or changes in regulations that may have occurred since their last training. Regular training helps to mitigate risks associated with pesticide use and ensures compliance with safety standards set by regulatory authorities.

The other options suggest less frequent training, which could result in insufficient knowledge of safety protocols and potential changes in pesticide practices, thereby increasing the risk of accidents and non-compliance. Regular annual training is crucial for maintaining a high standard of safety in pesticide handling.
