What do chemical cartridges do?

• A. Protects against gases and vapors using a sorbent material to capture the containments; meant for specific contaminants
• B. Filters particulates using a fibrous medium
• C. Provides an independent air supply
• D. Neutralizes chemical vapors by adsorption to water

Answer: (A)

Chemical cartridges are designed to remove gases and vapors by passing contaminated air through a solid sorbent material, usually activated carbon, which captures the contaminants as air flows through. They are selected for specific contaminants, with different cartridge types for organic vapors, acid gases, ammonia, and similar hazards, so you choose the right cartridge based on what you’re protecting against. This is different from particulate filters, which remove particles with a fibrous medium and don’t protect against gases. They don’t provide an independent air supply—that function belongs to supplied-air systems or self-contained breathing apparatus. The mechanism is adsorption (and sometimes chemisorption) on the sorbent, not adsorption to water, so cartridge performance depends on the sorbent’s capacity and the exposure conditions; once saturated, the cartridge must be replaced.
