Ch. 10- Mixing, loading, and application

What are 3 ways to help you decide whether you can safely mix two pesticides together for an application?

-Check the pesticide labeling. It may list the pesticides (and other chemicals) known to be compatible with the formulation. -Get a compatibility chart, which may be available from several sources (internet). -Test a small amount of the mixture before mixing large quantities of the pesticides together.

What safety procedures should you follow each time you apply a pesticide?

-Deliver the pesticide to the target site. -Check the delivery rate. -Check for appearance. -Avoid nontarget surfaces. -Operate equipment safely.

What types of empty pesticide containers can be rinsed?

-Glass, metal, and plastic containers. -Plastic-lined paper or cardboard containers. -Unlined paper or cardboard that can withstand the rinsing process.

Name four types of pesticide application that might require more personal protective equipment that that specified on the pesticide labeling.

-Hand-carrying application equipment (get for-real spray jug). -Entering the path of the released pesticide. -Walking into a just-treated area. -Using high-exposure application methods where the pesticide may engulf you. -Applying pesticides in enclosed spaces. -Adjusting pesticide application equipment. -Immersing hands and forearms in pesticides. -Applying into or across air currents. -Applying concentrated pesticides.

What should you do with an empty pesticide container?

-If containers are rinsable, rinse them as soon as they are empty. -Return all empty pesticide containers to the pesticide storage area or the container holding area when you finish your task. -Crush, break, or puncture empty containers that cannot be refilled, reconditioned, recycled, or returned to the manufacturer. -Dispose of containers in accordance with labeling directions and with any laws or regulations that apply.

What two precautions should you take to avoid getting pesticides into you water source at a mix-load site?

-Keep the water pipe or hose well above the level of the pesticide mixture, and use a device to prevent back-siphoning if necessary. -Avoid mixing or loading pesticides in areas where a spill, leak, or overflow could allow pesticides to get into water systems.

Why should you keep records of pesticide application?

-Records can establish proof of proper use. -Good records can save you money by improving your pest-control practices and your efficiency. -Records can help you reduce pesticide mistakes or misuse (double-drop). -Good records can help you reduce carryover by buying only the amount of pesticides you will need.

What are enclosed application systems?

An enclosure, such as a cab or cockpit, that surrounds the occupants and prevents them from coming in contact with pesticides outside the enclosure.

What should you do with rinsate that you create when you clean your pesticide equipment?

Collect the rinsate. Reuse it, if possible, or dispose of it as excess pesticide.

What four types of personal protection, beyond what you need during application, should you consider wearing while mixing or loading pesticides?

Front protection, face protection, protection from dusts, and protection from vapors.

When should you consider installing a pesticide containment system?

If you often mix and load pesticides in one place, or if you often clean equipment at one location.

What are closed mixing and loading systems?

Systems designed to prevent pesticide from coming in contact with handlers or other persons during mixing and loading.

What are the advantages of pesticide containment systems?

They can save time and money. They make spill cleanup easier, and they reduce pesticide waste by allowing reuse of rinse water and spill cleanup water. They also help prevent the harm that spills and runoff can cause to the environment or to people.

What two methods of rinsing can you use?

Triple rinsing and pressure rinsing.

When your are finished with pesticide handling tasks, what steps should you take for personal cleanup?
