One of the most essential requirements for us to live and stay healthy is breath. But we also need our bodies to breathe in air which provides us the oxygen, an essential for life. By exhaling, we release carbon dioxide — a waste gas our body has no use for. In certain instances, we need to shield ourselves as we inhale because of the harshness in the air around us. And that is where breathing tools help. In today's text, we will discuss the parts of each breathing tool that helps us from them all so that in any conditions our breath should be safe.
A respirator, which we wear just like this over our mouth and nose. It is used to purify the air that we breathe in. The inner part of the nose also filters the air we breathe before it reaches our lungs, saving us from harmful substances like dust or smoke etc. A respirator is composed of three hefty parts constructed in a complex manner— the filter, mask and straps.
Respirators are a special type of breathing mask that covers both the nose and mouth. It serves as a protective barrier against harmful particles and gases present in the air. The components of a breathing mask are somewhat different with respect to an ordinary respirator: the inlet valve, exhale vale and facepiece.
It is the thing that covers our nose and mouth (which typically sucks most teeth) to a facepiece usually made of soft, elastic material. This makes sure that it is comfortable to our skin.
A self-contained breathing apparatus, or SCBA for short, is a type of emergency response system. To the user, it supplies breathable oxygen and additionally guards him from poisonous gases as well as chemicals. The SCBA consists of four major components which are the regulator, cylinder, facepiece, and harness.
Another type of respirator is the supplied air respirator or SAR that has a hose through which clean air from an external source such as a compressor is drawn. This kind of respirator is typically used in areas where the air quality has become hazardous due to smoke or vapors as well. An SAR consists primarily of four components—the hose, regulator, mask and a waist belt.
