13.6 Spill Response: Control, Contain, Clean Up & OERS

Key Takeaways

  • Protect people first, then control the source of the leak, contain the spread, and clean up the spilled material.
  • Never hose a pesticide spill down with water; that spreads the contamination and can carry it into a drain or waterway.
  • Absorb liquid spills with an inert absorbent, sweep dry spills up without raising dust, and containerise the residue for disposal.
  • Keep a stocked spill kit at the mix and load site and a second kit on the application vehicle.
  • Responsible parties must report spills and releases to the Oregon Emergency Response System at 1-800-452-0311, available 24 hours a day year round.

Spill Response: Control, Contain, Clean Up & OERS

Why this matters: The last four leaves of Domain 8 are Control, Contain, Cleanup and OERS — the three C's plus the phone number. They are in that order because that is the order you do them in.

Emergency Spill Response Protocol (The Three C's & Incident Notification)

1. Emergency Spill Management: The Three C's (Control, Contain, Clean Up)

When an accidental spill occurs during storage, transit, mixing, loading, or application, the applicator's immediate, disciplined reaction dictates whether the incident remains a minor localized event or escalates into an environmental catastrophe. Applicators must execute The Three C's of Spill Response.

│                                                                        │
│  1. CONTROL THE SPILL (STOP THE SOURCE AT ONCE):                       │
│     • FIRST AND FOREMOST: Put on appropriate chemical-resistant PPE!   │
│       Never attempt spill response in bare hands or street clothes.    │
│     • Set upright tipped containers; close severed or leaking valves;  │
│       shut off power to spray rig pumps; clamp ruptured transfer hoses.│
│     • If a bag of dry powder is torn, roll the torn edge closed or     │
│       place the entire damaged bag inside a heavy plastic salvage drum.│
│                                                                        │
│  2. CONTAIN THE SPILL (RESTRICT THE SPREAD):                           │
│     • Isolate the spill immediately to prevent spread across the ground│
│     • Construct perimeter berms or dikes using absorbent socks, booms, │
│       cat litter (bentonite clay), vermiculite, sand, or dry soil.     │
│     • PROTECT SENSITIVE PATHWAYS: Cover storm sewer grates, catch      │
│       basins, drainage swales, wellheads, and stream banks.            │
│     • NEVER WASH DOWN A SPILL WITH WATER! Hosing down a chemical spill │
│       multiplies the contaminated volume tenfold and washes lethal     │
│       poisons directly into storm systems, aquifers, and waterways.    │
│                                                                        │
│  3. CLEAN UP THE SPILL (ABSORB, DECONTAMINATE & RECOVER):              │
│     • Liquid Spills: Spread absorbent granular clay or pads over the    │
│       puddle, working systematically from the outside perimeter inward.│
│     • Dry Spills: Gently mist dry powders with a fine water spray to   │
│       prevent airborne dust, then sweep up carefully into drums.       │
│     • Sweep saturated absorbent into heavy-duty 6-mil plastic bags or  │
│       DOT-approved open-head steel/poly salvage drums.                 │
│     • Surface Decontamination: Scrub hard surfaces with a neutralizing │
│       solution: 30% household bleach + heavy-duty detergent, or        │
│       hydrated lime slurry (especially effective for organophosphates).│
│     • Collect all decontamination wash water with fresh absorbent.     │

2. Spill Kit Engineering & Strategic Site Placement

Every pesticide storage facility, central mixing/loading pad, application vehicle, and nurse rig must maintain a fully equipped, clearly identified Pesticide Spill Kit.

Essential Information to Report During an Incident Call

When reporting a pesticide spill to OERS or ODA, the caller must provide:

  1. Exact geographic location of the spill (address, highway milepost, GPS coordinates, proximity to water bodies or wells).
  2. Chemical trade name, EPA Registration Number, active ingredient(s), and formulation type.
  3. Estimated total volume or weight of product released.
  4. Physical state of the spill (liquid, dry powder, expanding aerosol/vapor).
  5. Immediate environmental threats (threat to surface water, storm drains, school/residential proximity).
  6. Human injuries, chemical exposures, or symptoms observed.
  7. Immediate containment actions already underway.
  8. Caller's name, certified applicator license number, business name, and return contact phone number.
