2 Personal Protective Equipment (PPE) This module will help you:Understand PPE selectionUnderstand PPE care, storage, and disposal
3 Required PPE is determined by... The toxicity of the pesticideThe formulation of the pesticideThe activity you are performingMixing and loadingApplyingMaintenance operations
4 Read the label!! Follow directions for PPE Minimum requirements are given– use greater protection than label says!Note precautions
5 Chemical-Resistant Clothing Prevents most chemicals from reaching the skinPVC plastic, rubber, non-woven coated fabrics
6 Cotton, Denim, Leather: Not recommended for most pesticide applications!
7 Chemical-resistant Materials Watch for signs of degradation:color changespongyswollenjelly-likecrackedbrittle
8 Chemical-resistant Materials Read the labelWhat materials are resistant?

10 Personal Protective Equipment (PPE) Minimum:Long-sleeved shirtLong trousers or coverallsGlovesShoes plus socksHatProtect Yourself!
11 Coveralls Wear loosely over clothing. Zippers should be covered. Two-piece: top should extend well below the waist and remain untucked.
12 Chemical-resistant Suits Wears out with chemical contact over timeMade of rubber or plasticMay be too warmDrink plenty of water!Take frequent breaks!
13 Chemical-Resistant Aprons Use when:mixing and loadingcleaning equipmentFrom neck to kneesWARNING: aprons can get caught in machinery!
14 Use Gloves! Especially during mixing & loading Unlined and waterproof Check for holesIf spraying overhead, tuck sleeves inside gloves…… and fold the cuffs up.
15 What is wrong with these gloves? Lining can absorb pesticide!
16 NEVER use cotton gloves when applying pesticides… unless the label requires them.
17 Gloves reduce dermal exposure by 99% Exception: Methyl bromide and other fumigant gases can become trapped near skin and cause burns.
18 No gloves??Fluorescent dye shows how much pesticide can get on the hands while handling it.
19 What is wrong with this picture? Wear long-sleeved shirts!
20 Check the label to determine if you need specific chemical-resistant gloves, and what kind.
21 FootwearNo sandals!Consider wearing unlined, rubber boots... even if not requiredHang pant legs outside the boots!
22 Hats & Hoods Liquid-proof with a wide brim No absorbent materials! Chemical-resistant hoods on jackets
23 Protect your eyes when mixing concentrates or handling dusts or toxic sprays. Eyeware should be shielded on all sides!
24 Eyeware is critical while mixing and loading concentrates. Prevent splashback!
25 If goggles are required, so is access to an eyewash dispenser! A portable eyewash is recommended for people in the field without access to a stationary eyewash.
26 Prevent pesticide exposure through the respiratory system. RespiratorsPrevent pesticide exposurethrough the respiratory system.
27 When should a respirator be used? When the label requires itWhen exposed to spray mistWhen using dusts, gases, vapors, or fumigants
28 Air-purifying Gas masks Chemical cartridge respirators Mechanical filter respirators (dust masks)Chemical cartridge respirators
29 Chemical cartridge and canister respirators Both half-face mask and full-face mask stylesGet cartridges that are right for the chemicals you are using!
30 Air Supplying Use an air-supplying respirator when oxygen level is low when applying fumigants in enclosed areas such as grain binsSelf-contained breathing apparatus (SCUBA)
31 Which type of respirator is this? Air-purifying or air-supplying?
32 Always select equipment approved by: National Institute of Occupational Safety and Health (NIOSH)Make sure the cartridge or filter is rated for the chemical you are usingRead the label.
33 Use and Care of Respirators MUST have tight seal!Fit-check and make sure it works before every use.Replace filters each workday or sooner.Check valves to make sure they are in proper working order.
34 Fit test your respirators… after the initial purchasewhenever a different facepiece is usedAt least every year thereafterStates may have regulations
35 Qualitative Fit TestPicture? -beckyWith the respirator on, the wearer is exposed to an odorant, irritant, or taste agent.The wearer then breathes, moves head from side to side, up and down, grimaces, bends at the waist, and talks.The wearer reports any noticeable odor or taste agent that leaks into the mask.
36 NOTE: I am in the process of getting a picture for this slide. - hines Quantitative Fit TestA special instrument compares the dust particle concentration in the surrounding air with the concentration inside the respirator.The ratio of these concentrations is called the fit factor.Wearer performs same movements as in the qualitative test, and the device continues to measure the concentration of particles.
37 Fit check before each use! Positive pressure check: Put hand over exhalation valve and exhale gently. If there is pressure in the mask, it’s a good fit.
38 Fit check before each use! Negative pressure check: Cover cartridges with hands, inhale gently, and hold breath for 10 seconds. If the facepiece exhibits no leakage, the respirator fits properly.Facial hair does not allow a respirator to seal!
39 After each use, remove filters and wash the facepiece. Store in a tightly-sealed bag in a clean, dry location.
40 Get to Fresh Air Immediately if... You smell or taste contaminantsYour eyes, nose or throat become irritatedYour breathing becomes difficultThe air you are breathing becomes uncomfortably warmYou become nauseous or dizzy
41 Clean Up! Wash at the end of each day, including gloves and all PPE. Discard disposables and worn-out items!Launder pesticide clothing
42 Wash contaminated clothing in hot water with detergent.
43 Laundering Pesticide Contaminated Clothing Use heavy-duty liquid detergent for ECsUse 2 cycles for moderate to heavy contaminationRinse the washer with an “empty load”HeavyDuty2
45 Keep all PPE separate from pesticides in storage!!
46 Mixing and Loading Wear adequate PPE Do not mix where pesticides can contaminate water.
47 Prevent back-siphoning! Air gap: keep the water supply above the level of the mixture.Install a back-siphon valve (check valve).
48 Application Tips If a nozzle becomes plugged during an application… Do not remove your PPE!Use an old toothbrush to clean the nozzle. Never try to blow it out with your mouth.
49 Application Tips Avoid disposal problems mix only the amount you need for the application.Never leave equipment unattended!
50 Summary Use Personal Protective Equipment (PPE). Use chemical-resistant PPE if necessary.Wear, clean, and dispose of PPE properly.Use eyeware & respirator according to the label.Fit test respirators yearly and fit check them before every use.Follow the label instructions -- and then some!
