Safe Storage of Pesticides - Articles

  • Store pesticides in a clean, cool, dry, and well-ventilated building. Always lock the area to prevent entry by children and untrained persons. Mark the storage facility with an appropriate warning sign.
  • Maintain proper temperature control. For example, if emulsion-type materials freeze, the emulsion may be destroyed, resulting in loss of effectiveness and possible serious plant injury.
  • To avoid the danger of cross-contamination, do not store herbicides with other pesticides.
  • Keep dry materials above liquid materials.
  • Do not store pesticides where food, water, feed, seeds, fertilizers, or personal protective clothing and equipment (such as respirators) can become contaminated.
  • Store pesticides in their original containers. Never store pesticides in any food or drink containers.
  • Do not remove the labels.
  • Keep lids tightly closed.
  • Check containers frequently for leaks.
  • Clean up spilled chemicals promptly and properly. Dispose of broken or damaged containers and any pesticide waste in an approved and safe manner as directed on the product label.
  • Keep an inventory of all chemicals. Mark each container with the year of purchase.
  • Inform your local fire department of any chemicals (including fertilizers) stored in large quantity.
