The outbreak of fire requires a team of experts with the necessary facilities to rescue the victims in the structure. They must have the hose line, protective gears and other equipment for the service (Charles 2009).The operation team must have versed knowledge in the ventilation processes to make the work easy during the emergency.
Steps in RIT operation
The team of experts is to visit the site as early as possible to ascertain the kind of incident which has taken place. Fire rescue equipments must be transported to the site to ensure that there is safety in the place. The rescue search is done when all the experts have dressed in their appropriate cloths ready for the operation (Klinoff & Robert 2007). The equipment which they must have in place are the ladders, hose lines, protective cloths etc. to make the service easy. The ladder is then placed below the window or on top of the structure in case of roof rescue. Ventilation holes are then made to allow easy vertical ventilation. Two personnel are allowed to save the victim at the same time where one enters the room through the window to remove the victim while the other receives him/her in the ladder. The outside rescuer is to advice the victim to be calm sometimes for proper assistance from the rescuers. The process is repeated until the operation is accomplished.
This is a special rescue device commonly used in closed area to extinguish fire in case of fire break out. It is always an instrument made by the technology called lessons developed at a time when Mark Langvardt died. The man was an engineer of the Fire Department in Denver, Colorado at the time he died during the fire rescue operation. The device is very simple to construct and it can be used to serve several duties not just for extinguishing fire in Denver but it could be used in different places. The main issue in the application of Denver drill is that it is used by two people who are to be in the room where one of the rescuers must face below the window to be like the ramp to raise the victim (Klinoff & Robert 2007). The same rescuer is also to act as the one to capture the victim depending on the rate that the other rescuer can try save the victim with any single trial. The possibility of the rescuer to effect the movement but not allowing the victim to drop down then there is a chance of saving the victim from the window promptly.
Vertical and Horizontal Ventilation
This is a systematic removal of smoke and hot gases to move upwards from the structure. It is to be done when the vents are removed but it can also be done when an available hole in the roof is used to pass the smoke. The process requires two people who are versed in the fire fighting skills. They must also be equipped with rescue equipment like protective cloths, cutting tools, charged line and ladders which are very essential in the rescuing process. It involves opening of all the available openings in the very beginning then cut the roof at a point which is safe and close to the fire (Klinoff & Robert 2007). The large vent should be made since it is much better than many small vents. It has the capacity to reduce the possibility of mushrooming of the air thereby improving the inside state of the building. Its disadvantage is that it exposes the rescuer to high risk because of being on the roof when doing the job. It is also time consuming and cannot be easily practiced in the normal life situation.
This is a process of removing hot air and smoke to flow in a lateral direction from the structure. It is to be done when the windows of the building are destroyed and all the doors are let open to allow free circulation of air in the structure (Klinoff & Robert 2007). It is also faster than vertical ventilation since it only requires breaking the windows and opening the doors. In terms of resources it consumes very little resources and does not require a team of firefighters to succeed. The only disadvantage is that there could be mushrooming of the structure and it can be negatively affected by strong winds if proper care is not taken.
Types of ventilation
Forced ventilation is the process of removing hot gases mechanically from the building and it involves the following methods: hydraulic, negative and positive pressure ventilation.
This is the type of ventilation where the rescuer does the operation while standing in the middle of the building. It involves the use of hose line together with a fog nozzle and begins by breaking down the fire in the structure. The rescuer moves next to the door to attack the fire successfully using the hose line. The hose line is then directed towards the opening and the nozzle is placed widely to let the fog cover all the openings (Klinoff & Robert 2007). This will allow the heat and smoke to move into the stream and be ejected out of the structure smoothly. Its importance is that the method is quick and easy to perform since it does demand the users to organize fans or arrange for vent holes which need a lot of time.
This is a method that is characterized by pulling the air to move out of the structure forcefully. It is done by the use of electric vent fan, source of power supply, salvage cover and a fan jack. It is commonly used at a time of overhaul when the fire is knocked down. This is very important because it is a process that pulls smoke and hot gases along the vent fan for it to function successfully (Klinoff & Robert 2007). Its effectiveness is ascertained by the quantity of churning that results from the vent fan. The churning effect can be controlled by sealing the areas next to the fan with the salvage cover to prevent the air that is removed from the fan to siphon into the fan intake.
This is the most important forced ventilation which is more aggressive as compared to other methods of ventilation. It uses very limited resources but works the best in terms of its efficiency. It is used to remove hot air and smoke from the structure through ventilation. The process requires only a single hole to allow the smoke come out. The hole must be very tiny to allow for great pressure collection to spread the carbon dioxide in the fire.
The ladders should be placed side by side by the rescuers in a position bellow the window. Other members of the group are to be in the room to assist in fixing the ladder from inside. The tip of the ladder is to be placed below the window in the rescue position. One rescuer is to enter the window to remove the victim while the remaining one is to stand on the ladder to receive him during the rescue process (Charles 2009).The other fire fighter is to secure the ladder in place when another fire fighter enters the room to remove the victim. The fire fighter is to take the victim in his arms in case of young victim. An adult victim is received and advised to stay for a while at the window waiting for the rescuers to position themselves well.
The aerial ladder is to be put in the safest position of the roof on quite a distance from the source of fire. This is because it is required to be located in the strong part of the house so that the ventilation group can be safe from fire and collapse from the roof (Charles 2009). Placement of the ladder on the strong part of the roof allows the rescuers to identify the points where they can cut holes for ventilation purposes. It also allows the team to start working from the weak parts of the structure towards the strong areas of the roof moving towards the aerial ladder. It is very beneficial to use the roof ladder because it makes the ventilation groups have an opportunity to escape danger in case of high risk of fire spread.
Summary of what Killed the Rescuer
On March 4, 2012 a 34-year-old man who volunteered to help the victim died in the theater fireroom which broke out as a result of gas explosion in the house left many died. It also led to the death of the fire fighter when the roof collapsed during the operation killing him in the house.
The management system responsible for fire incidences should be developed with a well organized commander who is not to take part in suppression tasks in the fire department to boost the efficiency of the department. Full situational fire gadgets are to increase in size such as firefighters in the buildings and they are also to apply the risk management tactics to reduce the incidences of fire.
