Pesticide Spill Response

A pesticide spill is an emergency for the people nearby, the soil and any water. This guide explains how to plan ahead in general terms, while the label, your state agency and emergency services provide the actual response steps.

What counts as a spill?

A spill can be a few drops at the mixing site or a large release from a damaged tank or a container that tipped in a truck. Size matters for how you respond, but even a small spill needs attention because of the potential for exposure and for contamination of soil and water.

If a spill involves injury, fire, a road, a waterway or a quantity you cannot manage, call 911 in an emergency.

Spills on the road or near a farm entrance are a special concern because other people may arrive before help does. Warn traffic and keep people back from the area until responders say it is safe.

Why plan before it happens?

During a spill, people react quickly and may make poor choices. Having a plan, a kit and a shared understanding of roles makes the first minutes calmer. Write down who stops work, who keeps others away and who calls for help.

This article does not give cleanup steps because they depend on the product, the quantity and the setting. The label and your state agency provide those.

Practice is part of planning. Walk through a pretend spill once a year, preferably before the spraying season. Ask who would call, who would keep people away and where the label would be found. Adjust the plan based on what you learn.

What should a spill kit and plan include?

Keep the basic supplies in a known place near where you mix and store. The right items are described in extension and agency publications and vary with the products you use, so ask your educator for a list that fits your operation.

Post the emergency numbers and keep labels and safety data sheets where responders can reach them. Make sure everyone who handles products knows where the kit and papers are.

• Protective equipment suited to the label
• Absorbent and containment materials as recommended by your agency
• Clean water and soap for decontamination
• Labeled containers for waste
• Phone numbers for emergency help and your state agency

Who do I contact?

In a life-threatening situation, call 911. For product-specific advice, the label lists contact information for the manufacturer's emergency line and first aid statements. Poison specialists can advise on exposures.

Some spills must be reported to state or federal authorities, depending on the product and quantity. Do not rely on memory about thresholds. Ask your state lead agency what reporting rules apply to you.

Keep a written list of phone numbers on paper near the mixing area, since phones may be dead, out of reach or contaminated. Include the manufacturer emergency line printed on the label.

How do I protect people first?

Move people and animals away from the area and keep them upwind and uphill if you can do so safely. Do not enter a hazardous area without the right protective equipment and training, even to help someone. Responders are trained for this.

Anyone whose skin or clothing was contacted should follow the first aid directions on the label and seek medical advice. Keep the product name and label information available.

If you are alone, protect yourself first. A second injured person helps no one. Call for help, keep people away and wait for trained responders when the situation is beyond what you can safely manage.

What about water and drains?

Prevent product from reaching drains, wells, ponds and streams. What containment is possible depends on the situation and the equipment you have. When there is a risk to water, contact your state environmental or agricultural agency right away.

If a spill occurs near a well, tell your state agency and ask about testing before using the water.

What happens after the spill?

After the immediate danger has passed, talk about what happened. Update your plan and your kit. Document the event, including the date, product, estimated amount and actions taken, since records can be needed for agencies and insurers.

Check with a health provider if anyone has symptoms, even mild ones, and mention the product name.

Some farms invite their fire department and a local emergency manager to a walk-through. Responders often know of resources, such as hazardous materials teams, that a farmer would not otherwise think to call.
