Risk of Pesticide Exposure: 

Risk of Pesticide Exposure handling applying mixing loading 2

Decontamination Materials: 

Decontamination Materials clean water soap paper towels extra coveralls eyewash first aid kit 3

Spill Kit: 

Spill Kit Personal Protective Equipment (PPE) absorbent materials (saw dust, pet litter) sweeping compound to keep dry spills from spreading shovel, broom, and dustpan 4

Spill Kit continued: 

Spill Kit continued Heavy-duty detergent Fire extinguisher Closable, sturdy plastic container 5



Mixing and Loading: 

Mixing and Loading outdoors or ventilated area away from people, animals and food or feed 7

Avoid back-siphoning: 

Avoid back-siphoning 8

Personal Protective Equipment (PPE): 

Personal Protective Equipment (PPE) 9

Mixing and Loading: 

Mixing and Loading front of body protection (bib-top apron) face protection (eye goggles, face shield) respirator 10

Handling Containers: 

Handling Containers Do not tear open paper or cardboard containers. Tightly close containers after each use. Pour pesticides below face level. 11

Cleaning and Disposing of Pesticide Containers: 

Cleaning and Disposing of Pesticide Containers Read the pesticide label for container disposal information. 12

Cleaning and Disposing of Pesticide Containers: 

Cleaning and Disposing of Pesticide Containers Triple or pressure rinse containers immediately after use. Puncture or crush rinsed pesticide containers to make them unusable. 13

Triple-Rinse Containers: 

Triple-Rinse Containers Wear PPE. Drain concentrate. Fill container with water to approximately 20% of its volume. Replace lid and shake to rinse all interior surfaces. Drain the rinse water into spray tank. Repeat the process 2 more times. 1st rinse water 2nd rinse water 3rd rinse water 14

Pressure Rinsing: 

Pressure Rinsing Wear PPE, especially gloves and face protection. Drain concentrate. Push special nozzle through the side or bottom of the container while holding the container over the spray tank. Pressure-rinse for 30 seconds with water draining into the spray tank. Triple-rinse the container cap with slower flowing water. 15

Personal Protective Equipment: 

Personal Protective Equipment Read the pesticide label for PPE requirements. 16

Personal Protective Equipment: 

Personal Protective Equipment Consider type of application equipment when choosing PPE. Avoid re-entering the treated area while making the pesticide application. Dripping or partially clogged nozzles, a leaky hose or loose connection, increases your chance of pesticide exposure. 17

When pesticide fallout may occur, you should wear: : 

When pesticide fallout may occur, you should wear: chemical resistant suit with hood, gloves, footwear with sealed cuffs, and a full-face respirator or a half-face respirator with sealed goggles. 18

Personal Protective Equipment: 

Personal Protective Equipment When working in enclosed spaces you increase you risk of inhalation exposure. 19

Planning the Pesticide Application: 

Planning the Pesticide Application Read the pesticide label. Select the appropriate PPE and make sure it is in proper working condition. Clear all unprotected people from area to be. 20

During the application, : 

During the application, Take time to be sure the pesticide is reaching the target evenly and in the right amounts. 21

During the application,: 

During the application, Turn off the equipment whenever you stop. Check hoses, valves, nozzles, hoppers and other parts occasionally during the application. 22

After the application, : 

After the application, Clean the application equipment, PPE, and yourself. Complete the recordkeeping. 23

Cleaning Application Equipment: 

Cleaning Application Equipment Wash equipment on a containment pad. Wear PPE required by the label. BENEFITS avoid breaking parts reduce corrosion prevent clogging 24

Cleaning application equipment: 

Cleaning application equipment Clean the inside and outside. 25

Collect any rinsate: 

Collect any rinsate Sump pump in a drain to collect rinsate. Rinsate – washwater that contains a small amount of pesticide. Apply to labeled site following label directions. Dispose of as you would excess pesticide. 26

Closed systems improve safety: 

Closed systems improve safety Closed mixing and loading systems: help prevent pesticide contact reduce spills can be more accurate may require less restrictive PPE 27

Mini-bulk containers: 

Mini-bulk containers Can be adapted to closed systems to help reduce pesticide exposure. 28

Soluble bags: 

Soluble bags Package dissolves in the solvent (usually water) in the tank. 29

Enclosed application system: 

Enclosed application system Enclosed cab or cockpit with pesticide filtration system help reduce pesticide exposure. Remember: Remove all pesticide contaminated PPE before entering enclosed cab or cockpit. 30

Pesticide Containment System: 

Pesticide Containment System Catches spills, overflows, and rinsate. Made of impermeable material like sealed concrete or a synthetic liner. Pad should be concave with curbs or walls. Must have system to recover rinsate or spill. Required if you mix, load or clean equipment in one place. 31

Pesticide Storage: 

Pesticide Storage Proper storage Improper Storage 32

Pesticide Storage: 

Pesticide Storage Pesticide Storage private well surface water 200 ft. 50 ft. 33

Pesticide Storage: 

Pesticide Storage A separate pesticide storage building is the best. Identify the building as pesticide storage with a sign. Make sure pesticide storage facility is isolated and well ventilated. Storage building should be constructed for fire resistance. 34

Pesticide Storage: 

Pesticide Storage Sealed concrete with curbing for spills. Floor drains cannot be connected to sewers or septic tanks. Ventilation reduces fumes and dust. Fans should provide 3 to 6 air exchanges per hour hour. Keep cool, dry, and out of direct sunlight. curb floor drain ventilation system 35

Pesticide Storage: 

Pesticide Storage Lock your pesticide storage. Store pesticides in original containers with label intact. Do NOT store pesticides in soft drink bottles or other food containers. 36

Pesticide Storage: 

Pesticide Storage Metal shelving will not absorb pesticide and clean easily. Place larger metal drums and non-metallic containers on pallets. Store liquids below dry formulations. 37

Pesticide Storage: 

Pesticide Storage Mark containers with purchase date. Buy only the amount of pesticide you will need for the job or season. Keep inventory and records. 38

SARA Title III: 

SARA Title III Superfund Amendments Reauthorization Act of 1986 MSU Extension Bulletin E-2575 39

Highly Flammable Pesticide Precautions: 

Highly Flammable Pesticide Precautions Read the pesticide label. Contain oils or petroleum solvents. Store away from open flames and heat sources. Keep glass containers out of sunlight. 40

If fire occurs:: 

If fire occurs: Clear the area Inform firefighters about chemicals Consider potential explosion Contain fire materials 41

Transporting Pesticides: 

Transporting Pesticides Transport in back of truck with side and tail racks. Steel or plastic-lined beds are easily cleaned. Carry a spill kit. 42

Transporting Pesticides: 

Transporting Pesticides Never carry pesticides in the passenger section. No pets or people near pesticides. No food, feed, clothing near pesticides. Do NOT leave vehicle unlocked or unattended. 43

Transporting Pesticides: 

Transporting Pesticides Keep highly volatile pesticides separate. Do NOT transport damaged containers. Anchor containers. Protect pesticides from extreme temperatures. 44

Commercial applicators transporting pesticides: 

Commercial applicators transporting pesticides Regulation 637 requires: company name, business phone number and address, or company US DOT census. 45

3 C’s of spill cleanup: 

3 C’s of spill cleanup Control Contain Clean up 46

Control the spill: 

Control the spill Wear PPE. Stop the source of the spill. Keep people away from spill areas. Avoid any drift or fumes that may be released. 47

Contain the spill: 

Contain the spill Containment “snakes” can be used to surround the spill. Cat litter or fine sand can be used. Prevent spill from reaching any water source by blocking or redirecting it. 48

Clean up the spill: 

Clean up the spill Collect the absorbent materials. Place in a leak-proof container. Dispose of according to label directions. If spill on an impervious floor, use heavy-duty detergent to clean and decontaminate the area. 49

Spill Assistance: 

Spill Assistance Michigan Department of Agriculture Agriculture Pollution Emergency Hot Line 1-800-405-0101 If the product is on EPA’s Extremely Hazardous Substance list, the spill needs to be reported to the Local Emergency Planning Committee and the State Emergency Response Commission.
