Personal Protective Equipment and Emergency Response
PPE comprises the clothing and devices worn to protect the body from contact with pesticides. Wearing PPE can reduce exposure (dermal, inhalation, ocular, or oral) and thereby lower the chances of pesticide injury, illness, or poisoning. It is important that all pesticide applicators and handlers understand the protections and limitations of PPE. Proper PPE selection, use, and care are essential.
Although pesticide accidents and emergencies are rare, they do occur. Pesticides spilled on the ground or burning in a fire can contaminate water, soil, and air; damage plants; injure livestock, wildlife, or pets; and endanger the health of the applicator and emergency responders. Pesticide spills and fires may lead to financial loss due to cleanup, liability claims, and fines assessed by government agencies. Take all possible steps to prevent accidents, but be prepared in case of emergency.
After completing this chapter in its entirety, participants will be able to:
- Identify where on the label to find the minimum clothing and personal protective equipment (PPE) required to handle a given pesticide product.
- State the criteria to properly select skin, eye, and respiratory protection required by the pesticide label based upon expected use and exposure.
- Discuss how pesticide releases from spills and fires can endanger humans and the environment.
- Explain how to execute an emergency response plan.
Pesticide Hazards and First Aid
Pesticides are designed to be toxic to living organisms so they can control pests (e.g., plants, insects, rodents,
fungi, and bacteria). At the same time, pesticides must be used with special care to avoid harming nontarget organisms, including pesticide applicators, handlers, and anyone else exposed to the product. Pesticides can have both short-term
and long-term effects on humans. As a result, pesticide users need to be concerned with the hazards associated
with exposure to the chemical and not exclusively with the toxicity of the pesticide.
After completing this chapter in its entirety, participants will be able to:
- Identify common exposure routes for various pesticides and application methods.
- Discuss the appropriate first aid response to oral, ocular, dermal, and inhalation exposures to pesticides.
- Explain the hazard level classification system for pesticides, including the corresponding signal words.
Pesticide Application Procedures
Today’s pest management practices require modern equipment to apply a variety of pesticides. Pesticides may be
applied as sprays, dusts, granules, gases (vapors), fogs, baits, rubs, or dips. The vast array of application equipment must
be matched to the pesticide as well as to the size and type of the job. To make an effective, safe, and efficient application,
read the label first. In addition, properly select, operate, calibrate, and maintain your equipment.
After completing this chapter in its entirety, participants will be able to:
- Identify the factors (e.g., nozzles, volumes, pressures, and speeds) that affect calibration.
- Demonstrate how to determine the amount of pesticide concentrate and diluent to use.
- Explain how to choose appropriate drift reduction practices.
Pesticides in the Environment
Applicators and the public share concerns about how pesticides may harm the environment. Initially, hazards to humans were the primary reason the U.S. Environmental Protection Agency (EPA) decided to classify a pesticide as a restricted-use product. Now, more and more pesticide labels list environmental effects (such as contamination of groundwater or toxicity to birds or aquatic organisms) as reasons for restriction. Anyone who uses a pesticide—indoors or outdoors, in a city or on a farm—must consider how that pesticide affects the environment.
After completing this chapter in its entirety, participants will be able to:
- Describe how pesticide applications can affect the environment.
- Explain how to prevent pesticide drift, runoff, and movement to nontarget areas.
- Discuss how to prevent pesticide residue accumulation associated with mixing, loading, and equipment washing.
Planning the Pesticide Application
Planning is essential before beginning a pesticide application. To help plan, know how to:
• Select the right pesticide for the job.
• Review the label.
• Test for pesticide compatibility before mixing.
• Choose what personal protective equipment to wear.
• Transfer pesticides safely.
• Clean up after an application.
Careful planning and consideration of all details is the hallmark of professionalism.
After completing this chapter in its entirety, participants will be able to:
- Explain how to select appropriate pesticides and additives (if needed).
- Follow the label for safe mixing and loading.
- State some basic procedures that ensure the correct application of pesticides.
