6.3 PPE Care, Laundering & Worker Protection Standard Requirements

6.3 PPE Care, Laundering & Worker Protection Standard Requirements

Core Principle: Personal Protective Equipment (PPE) is only as effective as its cleaning, maintenance, and storage regimen. Contaminated, degraded, or improperly laundered protective gear transforms from a protective barrier into a dangerous chemical reservoir, causing prolonged, continuous dermal exposure. Establishing rigorous decontamination routines and adhering to federal Worker Protection Standard (WPS) employer mandates are essential to protecting applicators, handlers, and their families.

1. Routine PPE Decontamination & Inspection Protocols

Decontaminating PPE must become an automatic, disciplined routine at the conclusion of every pesticide application and work shift.

Step 1: The Golden Rule of Glove Removal

[!IMPORTANT] Always wash the outside of chemical-resistant gloves with soap and clean water BEFORE taking them off!

If an applicator removes unwashed gloves, bare fingers will touch contaminated glove cuffs and exterior surfaces, transferring concentrated pesticide residues directly onto clean hands. Once the outer glove surfaces are washed:

1. Loosen the fingertips of both gloves.
2. Peel the first glove off by grasping the clean cuff from the outside, pulling it partially inside-out.
3. Use the partially freed hand to peel the second glove off from the clean interior, fully reversing it.
4. Avoid snapping or flinging gloves to prevent aerosolizing contaminated droplets.

Step 2: The Water Inflation / Submersion Glove Leak Test

Never assume reusable chemical-resistant gloves are intact. Punctures from thorns, wire, tank sharp edges, or micro-cracks from chemical degradation are often invisible to the naked eye. Applicators must inspect reusable gloves daily before use:

1. Water Inflation Test: Fill each glove with clean water, fold or roll the cuff tightly closed to trap water pressure, and gently squeeze the hand section. Inspect the palm, webbed spaces between fingers, and fingertips for escaping water droplets or weeping pinholes.
2. Air Submersion Test: Roll the cuff downward to trap air inside the glove, submerge the inflated glove into a bucket of clean water, and squeeze. Look for escaping streams of air bubbles.
3. Immediate Disposal: If any leak, weeping pinhole, swelling, discoloration, or brittleness is detected, discard the glove immediately.

Step 3: Cleaning Reusable Protective Equipment

• Elastomeric Respirator Facepieces: Disassemble the facepiece daily by removing particulate filters and chemical cartridges (never submerge cartridges in water!). Remove inhalation/exhalation valves and head harnesses. Wash the elastomeric facepiece in warm water ($110^\circ ext{F} - 120^\circ ext{F}$) using a mild non-ammonia detergent or manufacturer-approved sanitizing wipe. Rinse thoroughly in clean running water and allow to air-dry on a clean rack.
• Chemical Splash Goggles & Face Shields: Wash lenses and frames in warm soapy water, rinse thoroughly to eliminate detergent films, and dry with a clean microfiber cloth. Never use harsh abrasive solvents or petroleum cleaners on polycarbonate lenses.
• Chemical-Resistant Aprons & Suits: Hang suits and aprons on heavy plastic hangers, scrub exterior and interior surfaces with detergent and warm water, rinse with a clean water hose, and allow to air dry completely.

Storage Protocols: Preventing Chemical Contamination

Clean, dry PPE must NEVER be stored inside pesticide storage buildings, chemical mixing sheds, or in the same compartment as spray tanks and chemicals. Volatile organic vapors present in pesticide storage rooms will permeate elastomeric facepieces and saturate clean clothing.

• Store clean respirators, goggles, and gloves in airtight, heavy-duty sealable plastic bags (e.g., Ziploc bags).
• Place sealed bags in a clean, temperature-controlled, dry storage locker, office cabinet, or designated clean handler locker room away from sunlight and chemical fumes.

2. Laundering Pesticide-Contaminated Work Clothing

Work clothing (long-sleeved shirts, pants, coveralls) worn during pesticide handling accumulates invisible residues. If laundered incorrectly, these chemicals transfer onto family garments, exposing infants and household members to toxic residues.

|                   STEP-BY-STEP PESTICIDE LAUNDERING PROTOCOL                            |
+-----------------------------------------------------------------------------------------+
|  1. Personal Protection:          Wear chemical-resistant gloves and an apron when      |
|                                   handling dirty pesticide laundry.                     |
|  2. Segregation:                  Wash pesticide clothing SEPARATELY from family wash.  |
|                                   Never mix with children's or household garments.      |
|  3. Pre-Rinse / Pre-Soak:         Pre-soak garments in a bucket or use the washing      |
|                                   machine pre-rinse cycle to flush surface residues.    |
|  4. Water Temperature:            Use the HOTTEST water available (minimum 140°F / 60°C)|
|                                   to maximize chemical dissolution and emulsification.  |
|  5. Detergent Selection:          Use HEAVY-DUTY LIQUID DETERGENT (e.g., Tide, Wisk).   |
|                                   Liquid detergents break down oil/solvent formulations |
|                                   substantially better than dry powder detergents.      |
|  6. Load Volume & Cycle:          Set washer to MAXIMUM WATER LEVEL with a SMALL LOAD to|
|                                   maximize dilution; run the LONGEST heavy-duty cycle.  |
|  7. Drying Method:                LINE DRY OUTDOORS in direct sunlight. Sunlight UV rays|
|                                   photodegrade residual chemicals; prevents dryer contam|
|  8. Washer Decontamination:       Immediately run an EMPTY complete hot water cycle     |
|                                   with detergent through the washer before regular loads|
+-----------------------------------------------------------------------------------------+

Liquid vs. Powder Detergent Dynamics

Pesticide formulations—especially Emulsifiable Concentrates (EC), crop oil adjuvants, and liquid suspensions—contain petroleum solvents, fatty emulsifiers, and hydrophobic surfactants. Heavy-duty liquid detergents contain high concentrations of non-ionic and anionic surfactants formulated specifically to bind and suspend oily soils in water. Powder detergents are engineered primarily for clay and particulate removal and perform poorly against solvent-bound chemical residues.

3. The Saturated Clothing Disposal Rule

There is a strict, life-saving regulatory limit to what can be laundered:

      TOXICITY CATEGORY I & II CONCENTRATE SATURATION RULE

  ┌─────────────────────────────────────────────────────────────┐
  │  IF clothing or coveralls are DRENCHED or SATURATED with    │
  │  concentrated pesticides bearing the signal words:          │
  │                                                             │
  │         • DANGER-POISON / DANGER (Category I)               │
  │         • WARNING (Category II)                             │
  │                                                             │
  │  ❌ DO NOT ATTEMPT TO WASH OR LAUNDER!                      │
  │  ✔ IMMEDIATELY STRIP OFF CLOTHING UNDER EMERGENCY SHOWER    │
  │  ✔ PLACE IN A HEAVY PLASTIC BAG                             │
  │  ✔ DISCARD AS HAZARDOUS CHEMICAL WASTE                      │
  └─────────────────────────────────────────────────────────────┘

[!CAUTION] Saturated fabric fibers absorb concentrated active ingredients and organic carriers into the interior cellulose core. Scientific studies confirm that even after multiple consecutive wash cycles in boiling water with industrial detergents, lethal concentrations of Toxicity Category I and II active ingredients remain embedded in the fabric. Attempting to wash saturated garments will permanently contaminate the washing machine drum, plumbing, and future laundry loads.

4. Worker Protection Standard (WPS - 40 CFR Part 170) Employer Mandates

The federal Worker Protection Standard (WPS) establishes enforceable legal duties for agricultural employers operating farms, forests, nurseries, and commercial greenhouse establishments. Commercial pesticide handling businesses operating in non-agricultural sectors under Indiana law (355 IAC 4) adhere to parallel occupational safety requirements.

Core Employer Legal Responsibilities

1. Cost-Free Provision of PPE: Employers must provide all required PPE specified on the pesticide label to handlers at no financial cost. Employers cannot charge employees or deduct wages for required protective gear.
2. Daily Inspection and Maintenance: The employer must ensure that all PPE is clean, inspected for tears, punctures, and defects, and in fully operational condition before each day of use.
3. Prohibition on Taking PPE Home: Employers must strictly prohibit employees from taking contaminated PPE or work clothing home to launder. The employer must clean, maintain, or contract professional laundering services for all handler PPE.
4. Commercial Laundry Notification: If an employer contracts with a commercial laundry service to clean pesticide-contaminated garments, the employer must inform the laundry management in writing:
   • That the clothing is contaminated with agricultural pesticides.
   • The specific health hazards and toxicity associated with the chemicals.
   • Safe handling procedures and the requirement to wear chemical-resistant gloves and aprons while sorting.
5. Clean Changing and Storage Areas: Employers must provide a clean, pesticide-free location away from mixing/loading zones where handlers can store personal street clothes, put on PPE, and remove contaminated gear without cross-contamination.

5. Decontamination Facilities & Emergency Eyewash Specifications

Under 40 CFR Part 170.509, employers must maintain fully stocked, immediately accessible Decontamination Supplies for all handlers performing mixing, loading, application, or equipment cleaning tasks:

+-----------------------------------------------------------------------------------------+
|                        WPS HANDLER DECONTAMINATION SPECIFICATIONS                       |
+-----------------------------------------------------------------------------------------+
|  1. Geographic Distance:          Located within 1/4 MILE of all handling activities    |
|                                   (or at the immediate mixing/loading station).         |
|  2. Water Volume:                 Minimum 3 GALLONS of clean, potable water per handler |
|                                   available at the start of the work period.            |
|  3. Washing Supplies:             Adequate supply of soap and single-use paper towels.  |
|                                   (Hand sanitizers or moist towelettes DO NOT qualify). |
|  4. Emergency Attire:             At least one clean change of clothing (coveralls)     |
|                                   instantly accessible for handlers in case of spills.  |
|  5. Emergency Eyewash Station:    If the pesticide label mandates protective eyewear,   |
|                                   the mix/load site must provide an emergency eyewash   |
|                                   delivering at least 6 GALLONS of water (or a plumbed  |
|                                   eyewash providing 0.4 gpm continuous flow for 15 min).|
+-----------------------------------------------------------------------------------------+

[!TIP] In field applications where operations are located more than 1/4 mile from a permanent facility, decontamination supplies must be transported on the application rig or support vehicle to ensure handlers always remain within the mandatory 1/4-mile safety radius.
