9 Cartridges/Canisters Must remove organic vapor intended GET RIGHT ONE FOR CHEMICAL YOU USE A prefilter usually needed Approved by NIOSH/MSHA

10 Replace Dust Masks, Prefilters, Canisters, Cartridges Immediately if trouble breathing Immediately if you smell/taste/feel: vapors or warning agents Usually 8 hours use is maximum

11 Fitting Air Purifying Respirators Have a FIT TEST to see if wearer can detect substance measure substance inside face piece Have a FIT CHECK close inlet (cut off air) inhale gently (face piece collapses) hold breath 10 seconds* *face piece should remain slightly collapses if working properly

12 Disposable/Reusable Protective Clothing isposable (cannot be cleaned) Chemical resistant Nonwoven (also coated) Dust masks, prefilters, some respirators eusable (can be cleaned) Rubber, plastic suits, gloves, boots, etc. Inspect thoroughly before re-use Fabric coveralls Should not be cleaned if drenched with concentrates eyewear, respirator, helmets most can be cleaned/reused

13 Washing Protective Clothing Wear gloves work in well ventilated area Rinse (hands or washing machine) Wash few items (at a time) Wash in washing machine Rinse twice Use two entire cycles (if badly contaminated) Run machine one cycle after removing clothes

14 Wash work clothes separately!!!

15 Maintaining Eyewear, Respirators Wash daily Use detergent/hot water Soak 2 minutes in mixture of: 2 tablespoons chlorine bleach/gal. hot water Dry/store clean area store in zip-closable plastic bag *most filters should be discarded a few can be washed/reused

17 Review Section Six Personal Protective Equipment

18 Q & A What legal responsibility do you have for wearing the personal protective equipment that the pesticide labeling list for your handling situation?

19 Q & A What does it mean when protective clothing and equipment are chemical resistant?

20 Q & A What should you do with your respirator between handling tasks?

22 Q & A How should contaminated, nondisposable protective clothing be laundered?

23 Q & A What is the difference between air-purifying respirator and an air-supplying respirator?

24 Pesticide Handling Decisions

25 All Phases of Pesticide Handling Involve Risk Transportation Mixing and loading Application Cleaning equipment Cleaning up spills Storage Disposal

26 Wrong Decisions Can Cause Wasted material Failure to control Target site damage Harmful off-site effects Fines/legal actions

27 Safe Mixing/Loading Safe site Protect water source Protective equipment Opening containers Transfer safely Clean up spills

28

29

30 Combining Pesticides Legal if label does not prohibit Fact not all pesticides mix/work Physical incompatibility Chemical inompatibility Label/chart/expert advice needed

31 Application Procedures Check deposition Check delivery rate Check appearance (milky, etc.) Avoid nontarget organisms Avoid nontarget surfaces Operate equipment safely

32 After Mixing, Loading, Application Cleaning equipment immediately avoids equipment damage avoids costly cleanup (solids, etc.) Clean outside/inside including nozzles use diluents in pesticide (or) ordinary water collect rinsate dispose of properly

33 General pesticides Clean with 2 pounds of detergent per 50 gallons of water Phenoxy herbicides Clean with 2 pounds of detergent per 50 gallons of water Rinse with 1 gallson of ammonia per50 gallons of water

34 After Mixing, Loading, Application (cont.) Personal cleanup Wash off protective clothing first Shower or wash in mild liquid detergent/water Put protective equipment/clothes in plastic bag Do not wash with family wash

35 Transportation, Storage, Disposal, Spills

36 Hauling Pesticides Back of truck tie down Never with or in Passengers Food, Feed Clothing, or other items In trunk of car Do not leave vehicle unattended

37

38

39 Always keep a first aid kit in the storage area for emergencies

40 Storage (see State Regulations) Secure (lock) Post (doors, windows) No Smoking signs Avoid water damage Control temperature Adequate lighting/ventilation Provide clean water Keep current inventory

41

42 Storage (see State Regulations) cont. No food, feed, seed Keep labels legible Use original containers Keep containers closed Inspect area often for damage No combustibles/volatiles Isolate waste (mark to avoid use)

43 Disposal Excess Pesticides Buy only amount needed Mix only about needed Use up according to label rate Apply to site in use directions Store if you can use shortly or until you can dispose of properly

44

45

46 Disposal Pesticide Wastes * * if it cannot be used it s a waste * Includes spills, saturated clothing Sometimes in special EPA approved landfills Almost never in sanitary landfills Incinerate (at federal/state approved site) Employ hazardous waste disposal company Never burn, bury, dump

47 Chem Waste, Inc For pesticide disposal cost information

48 Disposal Empty Containers (if applicable) Return to dealer for refill Recycle (after pressure rinse, etc.) Use soluble packaging Triple rinse for sanitary landfill (as allowed by label and law) Unrinsed check with Regulatory Authority Burn not allowed in many states Bury not allowed

49 Even when proper handling procedures are followed, pesticide spills can occur.

50 Spill Management Spill = any accidental release If major call Sate Authority or Chemtrec Remember: control, contain, clean up Control stop the source, stay at site Contain confine small use containment snakes large shovel, dike, etc. protect water sources absorb liquids, cover dry spills Clean up sweep up, decontaminate, neutralize (DON T HOSE DOWN)

51 Spill Kit Contents Telephone assistance numbers Chemical resistant gloves, footwear, apron Appropriate eyewear, respirator Containment snakes Heavy-duty detergent Shovel, broom, absorbent materials Fire extinguisher Sturdy plastic containers Specifics for your pesticides

64 Review Section Seven Pesticide Handling Decisions

65 Applying the Correct Amount

66

67 Apply the Right Dose Underdosing expensive/poor results Overdosing expensive/illegal

68 Label Rates for Use Rate based on formulation (1pt/acre) Rate based on active ingredient (1 pt/acre is 2 pt/acre of 50% EC) Rate based on % of final dilution (1/2% by volume) (1% by weight) Ready to sue formulations

69 Calibration Principles Appropriate equipment/size/type Proper nozzles for the job Check nozzles/outlets for uniform output Speed may be factor gravity flow when wheels turn powered speed important Pressure can be factor (4X increase to double rate)

70

71

72 Checking for Uniform Output Collect output of each nozzle (example: 2 oz./1 minute) Operate equipment over measured area (example: 4 oz./100ft)
