As a part of a continuous endeavor to eliminate the problems caused by MTLs and enhance the reliability of the protective system, many protection methodologies have been developed.
In Part 2 (Winter 2018) we elaborated on the specifics of each component needed for a fully functional personal protective system, which includes protection for head, hearing, eye, leg, feet, and hands.
Despite the simple and dependable performance of the conventional distance protective system, the reliability of distance protection is affected when infeed condition exists in MTLs.
So far, the focus of most studies on the firefighters' protective system has been on thermal protection, which combined with advances in material technology during the past decade, has greatly decreased burn injuries (Boorady et al. 2013).
Equipment from excessive pressure by relief valves is protected or in other ways but no protective system is 100% infallible.
These items of firefighters' protective system have been designed to provide protection against multiple hazards such as thermal threats (e.g. exposure to flame and excessive heat), toxic gas inhalation, and physical injuries (e.g. cuts, collisions, punctures, slips, falls etc).
Standard Soviet antimacassar deployment pattern, a 3-element protective system is depicted as 3 lace doilies protecting the arms and back of an easy chair.
The present numerical study on scale-like protection system enables pathways to design a lightweight and flexible protective system.
The protective system is independent of the control system, and provides protection from over speed, over temperature, vibration, loss of flame, and loss of lubrication.
However, literature reports that the efforts to improve thermal protection have inevitably increased the weight and bulkiness of the firefighters' protective system, hence, significantly compromising firefighters' mobility and comfort (Adams & Keyserling 1993; Boorady et al. 2013).
The United States already has the basic elements of a protective system.
