Embodiment Construction

[0034] exist image 3 The respiratory protection system worn by the user is shown in . The respiratory protection system includes a breathing mask 30 or helmet, and a breathing component 32 such as a fan-forced positive pressure breathing device commonly referred to as a powered air purifying respirator (PAPR), an air filter or a monitor. An air hose 34 or air tube connects the respiratory component 32 to the respiratory mask 30 to provide breathable air to the user 36 . The respiratory component 32 is designed to be worn by persons working in air with harmful pollutants, including respiratory hazards. The PAPR 32 has a housing 32a and one or more filter units 32b for filtering harmful pollutants from the surrounding air so that a user wearing the PAPR can work in polluted or hazardous areas. The PAPR 32 typically weighs in the range of about 0.3 kg to about 3.0 kg. An example of a PAPR weighing approximately 1.4 kg is disclosed and described in US Patent No. 6,575,165 enti...

Abstract

An anatomically fitted belt is used for carrying one or more waist-mounted respiratory protection components. The belt includes a main belt portion and a belt buckle portion. The main belt portion includes a back section, a left side section, a right side section, a left connective section between the back section and the left section, and a right connective section between the back section and the right side section. The back section is wider than both the left side section and the right side section. The main belt portion has a generally conical shape to be secured around a user's pelvic girdle and to align the respiratory component over the lumbar region of the user's spine to distribute a weight of the respiratory component. The belt buckle portion includes a right piece connected to the right side section of the main belt portion and a left piece connected to the left side section of the main belt portion.

Description

Background technique [0001] The present invention relates to respiratory protection systems, and more particularly to a waist worn respiratory component system including a decontamination belt for supporting the respiratory component. The decontamination belt is designed with ergonomic principles to provide users with better comfort and support. [0002] Fan-forced air-flow positive pressure breathing devices and other breathing components, commonly referred to as powered air-purifying respirators (PAPRs), are used by emergency personnel (hazardous material emergency personnel, police, fire, and civil defense systems), the military, and Used by other emergency responders for hazardous respiratory exposures. These respirators are also often used in industrial processes where the environmental hazards are obvious and quantifiable. Respiratory hazards can include hazardous gases, vapors and particulate matter. Respirators include breathing masks or other suitable face shields,...
