What are the common styles of respirators?

• A. Narrow and broad
• B. Heat and cold
• C. Solid and liquid
• D. Dust/mist and vapor

Answer: (D)

Respirator styles are described by what they protect you from. The most common types you’ll see are those that filter particulates (dust and mist) and those that protect against vapors and gases. A dust/mist style uses a filter to trap solid particles and liquid aerosols, which is typical when dealing with powders or spray mists. A vapor style uses cartridges or canisters designed to adsorb or neutralize gaseous contaminants, which is important when solvents or pesticide vapors are present. In pest control, you’ll often need protection from both particulates and vapors, so these two categories cover the typical hazards. The other options aren’t respirator styles—narrow vs broad isn’t a design category, heat vs cold isn’t about respirators, and solid vs liquid describes states of matter rather than protective equipment.
