Pre-Entry Fire Suppression & Ventilation Attack Tool
The Grantham MechVent is a Fire Attack tool I Invented using methods of Ventilation and suppresion by means of Water to cool a fire charged room. This tool is meant for a non rescue situation to be implimented from outside of a sturcture to prevent any risk to a FireFighter. This Tool is Attached to the Top of a ladder with standard fire hose connection. Using an Entry tip Nozzle on the front to cool all surfaces. The Main purpose of the tool is the Fog Nozzle wich sprays a fog pattern out of the entry window to create a ventilation vaccum to Exhaust the heat to help prevent a flashover.

We wish to ackowlege the extrordinary efforts of Dave Karasic and Shika Barman for all of their efforts in getting us this far.
I wish to Thank the following persons and organizations that have been important in the development of the device:

Patents Etcetera, an intellectual property firm based in the Boston area is introducing the Grantham MechVent™ (Grantham Mechanical Ventilator) to the fire-fighters' community.
Conceived and invented by Massachusetts resident, firefighter Bobby Grantham, the MechVent™ is a novel firefighting defensive tool which reduces the possibility of flashover, the most dangerous time of a fire. Its mode of action is to pull heat and smoke from the burning compartment, which is opposite to that of the typical approach to ventilating a burning compartment by blowing air into the structure by a fan to push the heat and smoke out, but both may be used simultaneously to good effect.
The Grantham Mechanical Ventilator reduces injury to humans at the scene as well as reducing property damage, by (1) pulling superheated air and smoke from the burning structure and (2) optionally by dousing the flames directly with a sprinkler flow when appropriate.
Additionally, the tool (3) reduces the spread of fire within the burning structure, (4) reduces the spread of fire to adjacent exposures, and (5) facilitates escape by people trapped inside the burning structure.
Finally, (6) once put in place the tool provides an unmanned means by which the preceding may be accomplished.
With all of the advancements in today's firefighter's personal protective equipment, it is still not designed to withstand flashover conditions for longer than just a few seconds. A few seconds may save a firefighter's life if he or she takes fast and appropriate actions, but the gear will fail quickly when exposed to the temperatures commonly found in flashover conditions, between 1,000°F and 1,500°F.
Rather than sending firefighting personnel into a burning structure before assessing the whether flashover is imminent, this invention will allow the conditioning of the environment in the compartment being entered to greatly reduce the chances of flashover occurring by removing built-up heat and smoke prior to entry. An additional benefit of removing smoke buildup is increased visibility, allowing a more accurate assessment of the situation therein, also increasing the safety factor. Further, the Grantham Mechanical Ventilator requires neither that a firefighter enter the burning building to put it in position nor remain in the building to operate it, thereby further decreasing the risk to firefighters.
Bobby is well qualified to offer opinions on matter concerning firefighting and public safety, since he possesses many certifications relevant to one involved in firefighting, as well as having many years of actual firefighting experience. Being a Nationally Certified Fire Officer II, as well as being a Fire Instructor I, Bobby knows the theories behind saving lives and property. But no advanced course of study prepares one to innovate in the field of firefighting equipment. Actual experience out in the field is required to focus one's thoughts most productively on ways to improve the process of firefighting. The Grantham MechVent™ is not just a better way of doing something; it represents both product and process innovation.
This tool was created because of the money. Not for the possibility of making money off it but because of the lack of money cities are willing to provide to the fire service to perform a professional and safe service. Too many Brothers and Sisters are loosing thier lives over lack of crew, preplans, or proper tools. This tool was created to help prevent some of these problems and hopefully safe a life.
The main goal of this tool is to Save a Life.
