Preventing Pesticide Exposure: A Guide for Safe Handling
Pesticides are essential tools in managing pests, but they can pose risks to human health if not handled correctly. This article provides a comprehensive guide on preventing pesticide exposure through four primary routes: oral, dermal, inhalation, and ocular.
Oral Exposure (Swallowing Pesticides)
The most common causes of oral exposure include accidental ingestion due to contaminated hands, food, drink, or improper storage near food or animal feed. To prevent oral exposure, store pesticides in locked, labeled areas away from food, water, and animal feed. Always wash hands thoroughly before eating or drinking, and never eat or drink in areas where pesticides are applied or stored.
Dermal Exposure (Skin Contact)
Direct contact with pesticide sprays, spills, or residues on plants, soil, or equipment can lead to dermal exposure. To prevent this, use appropriate personal protective equipment (PPE) such as gloves, long sleeves, and goggles when handling or applying pesticides. Avoid skin contact by careful handling, and clean any pesticide spills immediately. Wash skin thoroughly after exposure.
Inhalation Exposure (Breathing in Pesticides)
Inhalation exposure can occur due to prolonged contact in poorly ventilated areas, not using proper PPE, breathing vapors after application, using the wrong respirator, using an improperly fitted respirator, using tainted filters, cartridges, or canisters. To prevent inhalation exposure, use respirators or masks certified for pesticide use, apply pesticides in well-ventilated areas or outdoors, avoid breathing in spray mist, and follow label instructions on re-entry intervals after application to avoid inhaling residues.
Ocular Exposure (Eye Contact)
Splashing or drifting pesticide sprays or dust into the eyes can cause ocular exposure. To prevent this, wear chemical-resistant goggles or face shields while handling or spraying pesticides, avoid touching eyes with contaminated hands, and keep appropriate eye-washing stations accessible near pesticide use areas.
Additional Practices for Reducing Exposure
- Keep pesticides in their original containers with intact labels to ensure correct handling.
- Inspect storage areas regularly to detect leaks or damaged containers early.
- Integration of Integrated Pest Management (IPM) can reduce pesticide use by promoting alternative pest control methods and using pesticides only selectively as a last resort.
- Maintain a clean environment and eliminate entry points for pests, thereby reducing the need for pesticide use and potential exposure.
In summary, preventing pesticide exposure involves careful storage away from food and living areas, using protective gear, avoiding direct contact or inhalation during application, and adopting non-chemical pest control methods whenever possible. If exposure occurs, use showers, eyewash fountains, hand/face spray units, and other emergency equipment, call 911 if appropriate, report exposure, and follow emergency procedures.
