• Limit the amount of pesticide the company buys and stores to only what the company will use, sell, or distribute quickly.
• Always store pesticides in their original containers with the original label attached.

For pesticides in small portable containers (such as 55-gallon drums or smaller containers), the Environmental Protection Agency (EPA) regulates pesticide storage through specific storage instructions on pesticide labels. Some states regulate the storage of pesticides in small portable containers, so be sure to check state regulations.

Storage best practices

• Limit the amount of pesticide the company buys and stores to only what the company will use, sell, or distribute quickly.
• When given the option, choose refillable containers and return them to the pesticide seller for refilling.
• Read the pesticide label for specific storage and safety information.
• Keep pesticide storage facilities away from humans and livestock and do not locate them in flood-prone areas.
• Provide secondary containment when required.
• Situate pesticide containers so that leaks and spills cannot reach drains, surface water, ditches, etc.
• Secure pesticide storage areas to ensure no unauthorized entry.
• Post storage areas with signs reading “DANGER – PESTICIDES – KEEP OUT”.
• Do not store pesticides with incompatible pesticides or other chemicals.
• Keep pesticides separate from food, drinking water, animal feed, seeds, etc.

Safety tips for pesticide storage areas

• Always store pesticides in their original containers with the original label attached. However, if a pesticide container is leaking, transfer the chemical to a sturdy new container that can be sealed. Attach the original label to the new container or label the new container with specific information immediately.
• Purchase only the quantities of pesticides required for a single season to minimize the need for off-season storage.
• Keep the storage site neat and tidy. Pesticide handlers must be able to:
  • See pesticide labels,
  • Detect leakage or corrosion, and
  • Get to leaks or spills to clean them up.
• Store protective equipment and clothing in a nearby location that provides immediate access but is away from pesticides and their fumes, dusts, or possible spills.
• Provide an immediate supply of clean water and have an eyewash dispenser immediately available for emergencies. Soap and a first aid kit are also necessary.
• Establish procedures to control, contain, and clean up spills. Familiarize everyone with the procedures.
• Provide tools (like a shovel, broom, and dustpan) and absorbent materials (like clay, sawdust, or shredded paper) to clean up spills.
• Mark pesticide containers with the date of purchase and rotate inventory to ensure that the oldest material is used first.
• Keep the following:
  • An accurate, up-to-date stored pesticide inventory;
  • A file of product labels available for reference;
  • A file of safety data sheets (SDSs);
  • A building floor plan showing the exact location of pesticides; and
  • Emergency phone numbers at the storage area and in the office.
• Maintain an inventory of all safety kits and signs.
• Develop a fire emergency plan in consultation with the local emergency planning committee and fire, police, and sheriff’s departments. Notify the appropriate officials of the types of pesticides and quantities stored.
• Know and follow state and local fire codes. Consult with local fire authorities regarding the best fire extinguishing agent — water, foam, dry chemical, carbon dioxide, etc.
