9. Clean and store properly after use.

12. How to Conduct Fit Test of Respirator for Chemicals

Two main types of fit tests:

• Qualitative Fit Test (QLFT) – Uses substances like saccharin or Bitrex. User should not taste or smell the substance if the fit is proper.
• Quantitative Fit Test (QNFT) – Uses a machine (e.g., PortaCount) to measure leakage into the facepiece.

Steps:

1. Select correct respirator size.
2. Instruct the user to don the respirator.
3. Conduct 7 exercises (talking, turning head, bending, etc.).
4. Evaluate the seal via test results.
5. Record and certify the test.

13. Replacement Duration of Respirator for Chemicals

• Cartridges: Replace when:
  • Breathing becomes difficult.
  • You smell or taste chemicals.
  • As per manufacturer’s end-of-service-life schedule.
• Facepiece: Replace if cracked, damaged, or after 5–10 years (check specs).
• Filters: Replace when clogged or every 40 hours of use (or as specified).
• Check manufacturer instructions for specific durations.

14. How to Wash a Respirator for Chemicals

1. Remove cartridges/filters (do not wash these).
2. Use warm water with mild detergent (no solvents or alcohol).
3. Gently scrub the facepiece, valves, and straps with a soft brush.
4. Rinse thoroughly with clean water.
5. Air dry in a clean environment (do not expose to sunlight or heat).
6. Reassemble after completely dry.

15. How Many Times a Respirator for Chemicals Can Be Washed

• A reusable chemical respirator can be washed dozens or even hundreds of times if:
  • It is properly maintained.
  • Washing is done gently.
  • There’s no material degradation.
• Stop using if cracks, deformation, or wear are noticed after cleaning.

16. How Many Times Respirator for Chemicals is Reusable

• Reusable respirators (like elastomeric half or full face) can be reused indefinitely until:
  • The mask or parts wear out.
  • Manufacturer’s end-of-life guidelines are met.
  • Damage, contamination, or hygiene concerns arise.
• Filters/cartridges are not reusable — they must be replaced regularly.

17. What Respirator Should Be Used to Handle Pesticides?

• Use a NIOSH-approved respirator labeled for organic vapors and particulates.
  • Example: Half-face or full-face respirator with OV/P100 or OV/N95 cartridges.
  • For heavy use or fumigation: Powered Air-Purifying Respirator (PAPR) is preferred.
• Always check pesticide label for specific PPE requirements.
