 ===== Dead Man Zone ===== ===== Dead Man Zone =====
  
-The Dead Man Zone describes an area of un-burnt fuel which exists between a fire and personnel. The greater the distance between the fire and the personnel, the greater the likelihood that the fire will encounter a change in conditions as it progresses. This change in conditions can produce a rapid and unexpected increase in fire behaviour, quickly overrunning the exposed personnel.+[[https://en.wikipedia.org/wiki/Dead_man_zone|https://en.wikipedia.org/wiki/Dead_man_zone]] 
 + 
 +The term //dead man zone// was coined by members of the CSIRO research team in Australia who were investigating the spread of bushfires (Project Vesta). 
 + 
 +The **dead man zone** is defined as the area directly around a bushfire that is likely to burn within five minutes given the current wind conditions or an (un)anticipated change in wind direction. The distance this zone extends from the firefront is highly dependent on terrain, windspeed, fuel type and composition, relative humidity and ambient temperature, and can range from under 100 m to well over 1 km.

 ===== Emergency Communications ===== ===== Emergency Communications =====
 +
 +Communications is vital to safe and effective fire ground operations. In an emergenecy, being able to quickly and accurately relay information could be life saving.
 +
 +Within the appliances, there are two primary methods of communicating an emergency situation and requesting assistance:
 +
 +  * Radio - call "//Emergency Emergency Emergency//" and give the following information:
 +      - Call-sign;
 +      - Location;
 +      - Nature of emergency;
 +  * AVL Distress Button (//Press button for 4 seoncds//);
 +      * [[https://youtu.be/89wXSRevNDc?t=45s|Demonstration Video]]
 +
 +Mobile phone, to ComCen, 000 or any other receipient is a secondary emergency communications method.
