Class one ensemble is a situation where you offer yourself with optimal protection from any type of vapor and any type of liquid which is toxic. This is done by wearing protective materials to protect the breathing apparatus from these liquids and vapor. Class one ensemble gives quality protection to the person wearing the protective equipment. It is used in cases of favor or chemical released by terrorists or in case of biological attacks (Dolez & Khanh, 2009).
Functionality in class one ensemble. There are several elements contained in class one ensemble. These include footwear and foot cover materials, garments, specific respiratory protection equipment and gloves. Footwear is used to protect the feet from splitting toxic fluids and emitted gases which are harmful to the skin. On the other hand, garments are used to cover the entire body to protect it from any vapor and hazardous liquids. Gloves are used to protest the hand from any liquid and harmful vapor. There is also the specific respiratory protection equipment which protects one from inhaling toxic gases. Some of these equipment supply oxygen while others do not sup (Forsberg, K. 2001).
There are limitations of class one ensemble which include the difficulties in communication when wearing these equipment, another limitation is that some of these equipment does not supply oxygen to the user, for example, the Air-purifying respirator which cannot be used in a low oxygen environment. The last limitation, some do not give full protection. Like the half mask model does not protect the eyes.
In an example, a person who works in a company where there are tanks with harmful gases and a gas leak happens. The only option which he has is to use class one ensemble equipment like the Self-contained breathing apparatus (SCBA) which provides very pure dry air to the full facepiece mask through the nose and the user exhales the used gas to the environment. It provides complete protection but it is heavy to wear.
