The primary function of respiratory protective equipment (RPE) is to filter out harmful particles from the air, ensuring that the individual can breathe safely in environments where air quality is compromised. RPE is designed to protect the user from inhaling hazardous substances such as dust, fumes, gases, or other airborne contaminants that could pose health risks.

Using RPE correctly can significantly reduce the likelihood of respiratory diseases and other health issues that may arise from exposure to harmful airborne materials. This equipment is crucial in various industries, particularly construction, where workers may be exposed to substances like silica dust, asbestos, or chemical vapors.

The other options, such as providing warmth in cold conditions, enhancing visibility in low light, and reducing impacts from falls, describe functions associated with different types of personal protective equipment but do not pertain to the specific role of RPE in protecting respiratory health.
