EPA Revision Brings Big Change to the Farm

— Written By and last updated by

The United States Environmental Protection Agency (EPA) revised the Worker Protection Standard (WPS) in 2015. The Worker Protection Standard is a federal regulation designed to reduce the risk of illness related to pesticide exposure for agricultural workers and pesticide handlers on a farm and in a forest, nursery, or greenhouse. If an employer of any of the listed operations employs a nonfamily worker, they fall under the WPS. The first rollout of the new revisions came in effect January 2, 2017. A complete list of WPS requirements and exemptions can be found at https://www.ecfr.gov/ under Title 40, Part 170.

One of the biggest changes for agricultural workers and pesticide handlers will be to comply with revisions to Personal Protective Equipment (PPE) in order to become consistent with the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA). Individuals will need to meet OSHA requirements to ensure respirators are effective by completing a medical evaluation, fit test, and training.  This will have a bigger impact than I believe most are aware. Information on specific PPE can be found on individual pesticide labels. Read PPE requirements carefully, as there may be additional requirements during the mixing and loading process for some products.

Medical clearance is the first step in the compliance process, which will determine if the employee is physically fit to wear a respirator.  According to the North Carolina Agromedicine Institute, the employer must identify and pay for a physician or licensed health care professional (PLHCP) to perform a medical evaluation using the OSHA medical questionnaire or equivalent method. The employer must allow the employee to complete this evaluation during normal working hours or at a time and place that is convenient for the employee. The PLHCP must provide the employee with a statement of medical clearance to return to the employer. Alternative options are available online that could grant medical clearance immediately or may require a visit to a PLHCP for an in-person evaluation.

Once medical clearance is obtained, the employee should be fit tested to ensure the respirator forms a complete seal around their face. This test should be performed with the same make, model, style, and size of respirator that will be used when handling pesticides. Fit tests should be conducted annually and for each type of respirator you plan to wear, including particulate-filtering face masks (dust masks). Records of the medical clearance and fit test should be kept for two years by the employer.

The final step includes training to ensure pesticide handlers know how to use a respirator properly prior to initial use. Retraining is required annually or when workplace conditions change, a new type of respirator is used, or when problems in the employee’s use indicates need.

There are three commonly used pesticides that come to mind when thinking about the new respirator requirements: paraquat (Gramoxone), chlorpyrifos (Lorsban), and acephate (Orthene). Disclaimer – this is not a complete list and many generic products are available with the same active ingredient listed. It is the applicator’s responsibility to read and follow each specific product label that they use. Farmworkers and employers need to take a close look to see if they are in compliance to the new regulations. Future fit test clinics are being scheduled through our office to help applicators and employers.
