According to EPA criteria, what type of respirator must you wear when applying liquid pesticide products from Toxicity Class I?

• A. A A simple dust mask
• B. B A NIOSH-approved respirator with an organic vapor cartridge or canister with any N, R, P, or 100-series prefilters
• C. C A half-face respirator with organic vapor cartridge
• D. D A full-face respirator with P100

Answer: (B)

When applying liquid pesticide products, you must protect yourself against the organic vapors released by the product. EPA criteria specify using a respirator that is NIOSH-approved and equipped with an organic vapor cartridge or canister, plus compatible prefilters (N, R, P, or 100-series). This setup ensures you have both vapor protection and particulate filtration, and it is an officially approved combination for pesticide work. A simple dust mask offers no vapor protection, so it isn’t acceptable. A half-face respirator with an organic vapor cartridge could meet the standard if it’s NIOSH-approved and used with the correct prefilters, but the wording that best matches EPA criteria is the explicit combination of a NIOSH-approved respirator with an organic vapor cartridge or canister and the appropriate prefilters. A full-face respirator with P100 focuses on particulates and doesn’t, by itself, guarantee organic vapor protection unless it also has an organic vapor cartridge.
