The Health Hazard Evaluation Program received a request from a health and safety manager at a government agency concerned with potential exposures when employees manually applied pesticides into rivers to control sea lamprey larvae. Sea lampreys (Petromyzon marinus) are parasitic fish in the Great Lakes, the Finger Lakes, and Lake Champlain. In a typical treatment year, 30 to 40 U.S. tributaries receive applications of 3-trifluoro-methyl-4-nitro-phenol (TFM) and Bayluscide(TM). In 2012, an estimated 56,000 kilograms of TFM and 1,000 kilograms of Bayluscide were applied. During our evaluation, we (1) observed employee work practices and use of personal protective equipment (PPE) when applying pesticides; (2) looked at health and safety records and documents; (3) asked employees about their work, use of PPE, and work-related health and safety concerns; (4) measured TFM and Bayluscide on work surfaces, work clothing, exposed skin, and glove liners worn under protective gloves; and (5) measured carbon monoxide in a portable laboratory and a portable workstation powered by a propane generator. We found pesticides on work surfaces, PPE, personal clothing, and skin of employees, and a high carbon monoxide reading in a portable workstation. We observed inconsistent and inappropriate reuse of PPE, inconsistent hand washing methods, and some worksites where clean water was not available. We saw employees transfer, handle, and mix pesticides in open containers, which could lead to spills and tracking pesticides out of the work area. During our interviews, employees indicated that they were generally aware of pesticide exposure routes and health risks from exposure, and they wore eye protection and chemical resistant gloves when mixing and applying pesticides. Fewer than five employees reported skin irritation from TFM, skin rash, and poison ivy. We recommended the employer (1) enclose pesticide transfer and mixing equipment; (2) install washing stations so that employees can clean their boots, PPE, and skin; (3) develop PPE cleaning and storage procedures; (4) provide employees with clean water; and (5) reroute generator exhaust. We recommended employees (1) use required PPE and clean it before storing or reusing, (2) wash hands and face with clean water and soap after handling pesticides, (3) change clothes when they become contaminated with pesticide and at the end of the work shift, and (4) report all health and safety concerns to your supervisor.
