In an industrial or manufacturing context, the term "respiratory" may refer to equipment or systems designed to protect workers from inhaling harmful substances or particles that may be present in the air.
This may include things like respirators, air purifying systems, and other devices that are designed to filter or purify the air that workers are breathing. Respiratory protection is an important aspect of occupational health and safety, and is often required in industries where workers may be exposed to hazardous materials or environments.
