The Three C's of Spill Management
Control, Contain, Clean Up
Immediately upon discovering the spill or leak work to control it. Do not allow any further spills or leaks to happen. Control the flow of the spilling material by:
- Leaking containers → placed into other containers
- Ripped bags → placed into larger plastic bags
- Leaking sprayer → turned off
- Larger leak → plug the hole (safely)

After the leak or spilling action is stopped work to contain the spill. Use methods best fitting to the type or pesticide.
Contain the Spill
Liquid Pesticide Spills
Dry Pesticide Spills
To the best of your ability, you need to clean the spill. Similar to containment, how to clean up the spill will vary based on the type of pesticide that spills.
Clean Up the Spill
+ Liquid Pesticide Clean-up
+ Dry Pesticide Clean-Up
+ Decontamination
+ Neutralizing the Pesticide
Liquid Pesticide Clean-Up
For large liquid spills, sometimes it is possible to pump or vacuum liquid into a spray tank to be applied or disposed of later. We will go into pesticide disposal later in the module.
If it is not possible to pump or vacuum the liquid up, spread absorbent material over the spill area, sweep it up or remove it with a shovel, and place it in a heavy-duty plastic bag. Keep adding the absorbent material until all liquid is soaked up.
- Absorbent Material
- Broom and Pan
- Shovel
- Large Plastic Bags
Dry Pesticide Spills
For dry pesticide spills, a small mist of water can cause the pesticide to clump and stop spreading.
Decontamination
After removing as much material as possible, we must decontaminate the site.
- Do NOT hose down the site with water.
- For non-porous surfaces use a small amount of water and a strong detergent (some labels have suggestions for what detergent to use for a specific chemical.)
- Add absorbent material, sweep up, and bag (as before) until removed.
- If the spill occurred on soil, it may need to be neutralized by removing the top 2-3 inches of soil.
- Sometimes, the SDS recommends mixing activated charcoal into the remaining soil. Or it may ask for the remaining soil to be covered with a layer of lime and fresh topsoil.
- Absorbent Material
- Broom and Pan
- Large Plastic Bags
- Detergent
- Shovel

Liquid Pesticide Spills
- After you stop the source of the spill – do everything possible to keep the spill from spreading or getting worse.
- Construct a dam using soil or use containment tubes filled with straw for larger spills.
- For smaller spills clumping kitty litter can be effective.
Neutralizing the Pesticide
Some pesticides need to be neutralized. This can be found on the safety data sheet (SDS). Follow the instructions carefully.
For example, the SDS may require that you mix full-strength bleach with hydrated lime and work it into the spill site with a course broom. Remove with absorbent material and a broom and pan. Repeat several times.
- Absorbent Material
- Broom and Pan
- Large Plastic Bags
Dry Pesticide Clean-Up
For dry pesticides scoop up for reuse if possible.
If the pesticide is too dirty or wet, then scoop it up, place it in a plastic bag, and seal it.
After this, sweep up what you were unable to scoop. Because sweeping kicks small particles up, it is recommended that you apply a sweeping compound before beginning. Sweeping compound adheres to small particles and keeps them out of the air. This reduces inhalation exposure.
