Preventing Agricultural Chemical Exposure: A Safety Program Manual

• Agricultural chemicals that are applied to the fields remain on the plants in a transparent form called residues. You may not be able to see, feel, smell, or taste the chemicals, but you are being exposed.
• The employer must wait a defined period of time before letting workers back into the field. This is called the "Restricted Entry Interval." Even after the Restricted Entry Interval, however, it is not completely safe. The fields still have pesticide residues on the plants that can be dangerous if absorbed or ingested.
