10.3 Spill & Emergency Response — Control, Contain, Clean Up

10.3 Spill & Emergency Response — Control, Contain, Clean Up

A pesticide spill is the moment when every other competency is tested at once, under time pressure, usually alone, and often on the shoulder of a road. The federal core competency standards at 40 CFR § 171.103(c)(2) require a certified applicator to know the procedures for responding to a pesticide mishap, and there is no partial credit in the field.

The entire procedure compresses into three C's — Control, Contain, Clean up — with one non-negotiable step in front of them.

Step Zero: Protect Yourself

Put on PPE before approaching the spill. The single most common way a small spill becomes a hospitalization is a well-intentioned person walking into a puddle of concentrate in ordinary work clothes.

• Consult the label for the product's PPE requirements — carry labels in the vehicle (Section 10.1) precisely so they are available at this moment.
• At a minimum: chemical-resistant gloves, chemical-resistant footwear, eye protection, and coveralls. A respirator is required if the product's label or the vapor situation calls for one.
• Approach from upwind, and stay upwind and upslope.
• If the spill involves a fumigant, a highly volatile product, an unknown material, a confined space, or a fire, do not approach at all — evacuate, isolate, and call 911.

Never leave the spill unattended. One person stays to keep people, children, livestock, and pets away and to direct traffic; another calls for help and brings equipment. If alone, secure the area as best you can before leaving the immediate scene to call.

        PPE FIRST — before any of the three steps

1. Control — Stop the Source

• Set a leaking container upright and plug or patch the leak.
• Shut off the pump, close the valve, or stop the flow.
• Move a leaking container into a salvage drum or oversized overpack container.
• If a tank is leaking, transfer the remaining contents to a sound tank.

2. Contain — Stop the Spread

The goal is to keep the material out of water and out of soil, in that order of urgency.

• Dike the perimeter with a berm of soil, sand, or absorbent socks. Work from the outside edge inward so you are not pushing the spill ahead of you.
• Block the pathways — storm drains, culverts, ditches, and floor drains.
• In New Mexico this step is urgent and specific. Section 6.2 established the water context: acequias are community ditches that recharge shallow domestic drinking wells, irrigation laterals run directly into cropped fields, and arroyos carry storm flow into rivers. Coarse, low-organic-matter valley soils give a spilled, water-soluble product very little to bind to. A spill that reaches an acequia, an irrigation lateral, or an arroyo is no longer a contained incident.
• Cover a dry spill (dust, granules, powder) with a tarp or plastic sheeting to stop wind from spreading it. Do not sweep a dry spill in a way that raises dust.

3. Clean Up — Collect and Decontaminate

• Absorb liquid with cat litter, vermiculite, sawdust, activated charcoal, or commercial sorbent pads. Work from the outside in.
• Sweep or shovel the absorbed material and the dry spill into a labeled, sealable container — a drum or heavy-duty bag marked as pesticide waste.
• Remove contaminated soil. On unpaved ground, scrape up the visibly contaminated soil to a depth appropriate to the penetration and treat it as pesticide waste.
• Decontaminate the surface. Many labels and manufacturers recommend a decontamination solution — for many products a dilute bleach solution, for phenoxy and sulfonylurea herbicides an ammonia solution as described in Section 8.1. Check the label; never mix bleach and ammonia, which produces toxic chloramine gas.
• Do not hose the spill down. Water multiplies the volume of contaminated material, carries the pesticide into soil and toward drains and ditches, and turns a shovel-and-drum problem into a groundwater problem.
• Dispose of everything as pesticide waste — absorbent, soil, gloves, coveralls, brooms, and the salvage container. Section 10.4 covers the routes.

The Spill Kit

Every service vehicle and every storage area needs one, and it needs to be complete before it is needed.

Who to Call, and When

Reporting judgment. Applicators sometimes hesitate to report, fearing enforcement. That instinct is backwards. A promptly reported and properly managed spill is an incident. An unreported spill that is later discovered in an acequia is an enforcement case, and Section 1.1 established the exposure: a violation of the Pesticide Control Act is a petty misdemeanor under NMSA 1978, Section 76-4-34, with a civil penalty up to $1,000 for each willful or repeated violation and license action available under Section 76-4-23.

Two Special Cases

Highway Accident

Protect life first: check for injuries, call 911, and warn oncoming traffic. Tell the dispatcher what product is involved, the EPA registration number, and the approximate quantity — this is why the labels ride in the vehicle. Keep bystanders upwind and away. Do not attempt cleanup that exceeds your PPE, your training, or your kit.

Pesticide Fire

• Evacuate and call 911 immediately. Burning pesticides generate highly toxic combustion products, and the smoke plume is the primary hazard to the surrounding area.
• Tell responders what is burning — this is where the advance inventory and site map from Section 10.2 pay for themselves.
• Stay upwind and out of the smoke.
• Contain firefighting water if it can be done safely. Runoff from a pesticide fire is contaminated and must be kept out of ditches, acequias, and arroyos.
• Do not re-enter the building.

Documentation

When the emergency is over, the paperwork is not optional:

1. Write down what happened — date, time, location, product, EPA registration number, quantity, cause, what was done, who responded, who was notified, and what was disposed of and how.
2. Photograph the scene and the cleanup.
3. Notify the employer and the insurance carrier promptly.
4. Keep the records. Section 1.3's two-year retention is the floor; incident files justify longer retention.
5. Remember from Section 11.2 that NMSA 1978, Section 76-4-25 allows a damaged party to file a verified loss report with NMDA, generally within sixty days from the time the loss becomes known or before fifty percent of a damaged crop is harvested. Your contemporaneous record is the evidence that answers it.
