Properly Cleaning and Storing Respirators

Agricultural Tailgate Safety Training for Operators and Supervisors
Agriculture and Natural Resources
Agricultural Safety and Health Program

Objective: To be able to clean and store respirators according to the presented guidelines.

Trainer’s Note

Using proper cleaning and storage practices ensures that respirators remain effective and uncontaminated. Present the following scenarios and discuss the storage practices. Review, demonstrate, and practice the proper cleaning and storage procedure.

Common mistakes that limit the effectiveness of respirators:

  • Upon returning from the field on a hot and humid day, a worker haphazardly removes the personal protective clothing. The worker pulls off the respirator and hangs it on a nail in the barn, next to a pesticide container.
  • Rather than taking the time to put the respirator away, a worker tosses it on the dashboard of the truck. The truck is parked in a very sunny spot.
  • A respirator is in an enclosed cab. The cartridge is inside the sleeve of a plastic glove. The respirator has been there for two months.

Review the true or false quiz.


Respirators should be stored away from dust, sunlight, heat, extreme cold, excessive moisture, and damaging chemicals. Respirators, a piece of personal protective equipment (PPE), must be stored away from personal clothing and pesticide-contaminated areas. Change filters and dust mask according to the manufacturer’s instructions or when it becomes hard to breathe. Change cartridges according to the manufacturer’s instructions; if a substance taste or smell is noticed; or if eyes, nose, throat, or lungs become irritated.

Clean a dual cartridge using the following procedures:

  • Following the manufacturer’s instructions, wash reusable respirator face pieces. The face pieces should be cleaned with disinfecting soap, thoroughly rinsed and dried.
  • Dispose of cartridges and prefilters when you smell or taste contaminants, or if your eyes, nose, or throat become irritated (they cannot be cleaned). They must also be replaced if they show any sign of damage.
  • Disassemble the respirator, following the manufacturer's instructions.
  • Inspect the parts and replace damaged or worn parts.
  • Wash hands before and after cleaning.
  • Clean the inhalation and exhalation valves in a mild soap. Don’t damage or distort the valves during cleaning.
  • Air dry the parts that have been cleaned. They must be completely dry before they can be reassembled.
  • After reassembling, check seals and gaskets for tightness and leaks.

Storing Respirators

Clean respirators should be stored in nonporous, sturdy, airtight containers (like a re-sealable plastic bag). To avoid collecting dust, the respirator should be put away as soon as it is dry. Respirator face pieces and valves should be stored in a manner that does not distort the shape. Keep the respirator in a cool, dry cabinet specifically designated for storage.

Review The Following Points

  • Clean respirators after each use.
  • Cartridges and prefilters should be disposed after they are “used up” and cannot be cleaned.
  • After cleaning, store respirators in a cool, dry place.
