pesticide storage first steps
Pesticide Storage : First Steps
  • Growers need to conduct an inventory of the pesticides they have.
  • OR-OSHA has different regulations for general use pesticides and restricted use pesticides.
    • General Use: OAR 437-004-1680 (1-5)
    • Restricted Use: OAR 437-004-1680 (1-9)
  • If restricted use products are present the rule applies to all pesticides in storage (437-004-1680(1-9).
  • Oregon OSHA looks for HAZARDS.

Is hard to do when there

Isn’t one.

Control the Conditions
  • Excessive freezing or heat may cause containers to break, melt, explode, and some pesticides to volatilize, drift, degrade
  • Use exhaust fans to reduce temperature, remove dust and vapor to the outside
  • Keep storage area cool well-ventilated, and dry
Provide Adequate Lighting
  • Lighting equal to 20 foot candles
  • For reading labeling, spotting leaks, and cleaning up spills
  • Use spark-proof fixtures and switches!

  • Electrical wiring must comply with Division 4/S
  • When dispensing a flammable or combustible liquid must comply with Division 4/H

or osha pesticide requirements restricted use pesticides
OR-OSHA Pesticide RequirementsRestricted Use Pesticides

restricted use pesticide requirements

Store by category, not by the alphabet!

restricted use requirements

Seal floors and shelves to prevent the absorbtion of hazardous chemicals

pesticide storage regulations restricted use
Pesticide Storage RegulationsRestricted Use

When the storage area contains enough chemicals that a leak or

spill could cause material to leave the confines of the building, there

must be methods or means to contain

the material.

SPILLS: Prepare in Advance – Spills in Storage are Concentrates!







  • Cleanup of some chemical spills may fall under Division 4/H (Haz Waste Op & Emergency Response)
  • Containers can be damaged in transit and can leak, dissolve or be ripped.
  • Receivers should be aware of these problems.
  • Is there a plan for addressing these issues?
Pesticide Spills

WA Ecology

  • PPE requirements vary depending on the type of spill.
  • Growers need to know their limit: when is the spill too big to clean up safely.
  • Do they have an outside contractor for cleanup?
