What is the purpose of the color coding on air-purifying respirator cartridges?

The purpose of the color coding on air-purifying respirator cartridges is to specify what types of contaminants they filter. Each color represents different types of chemicals and hazards, allowing users to easily select the appropriate cartridge for the specific environment and contaminants they may encounter. This system helps ensure that individuals are protected from inhaling harmful substances by matching the right cartridge with the relevant airborne hazards.

Color coding is essential because it provides quick and easy identification in the field, which is especially critical in emergency situations or when working in environments with multiple hazards. This system enhances user safety and efficiency in selecting the right personal protective equipment (PPE), ultimately reducing the risk of exposure to harmful airborne contaminants.
