Firefighting Essay

Aerial firefighting is becoming the main process of putting out wildfires and forest fires. This process was used in the 1920’s when someone attempted to drop water from an aircraft onto a fire and failed, but eventually succeeded over time. In 1935, the (AFCEP), also known as the Aerial Fire Control Experimental Project was created for this occasion of multiple wildfires everywhere in the world. The original way to deal with fires took longer to do because fire trucks could only hold a certain amount of water and when they ran out of water, they would have to drive a far distance to find water. Helicopters can supply tons of water and with the ability to fly, they can move

This device was able to extinguish small, controlled fires created with an alcohol accelerant, proving that the concept is viable

Firefighters do more than just put out fire. It is not just a one sided job. There is a medical side of the firefighter job. They have house calls constantly for people requiring medical attention. It is quite a bit more than just fire. The calls that they go on are mostly medical rather than structure fires. They also go to

Firefighting tactics, like firefighting itself, has a history step in tradition but must also adapt to modern technology and science to stay relevant. Recently, fire research has provided the fire community with new tactics such as fire flow path, pencilling and transitional attack. While all three tactics have their merit, transitional attack has been shown to benefit both the firefighters and civilians in measurable ways.

The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out fire.

We are the most technically advanced nation in the free world but yet we have not been able to reduce the number of firefighter fatalities over the years. Its one of the great mysteries of the world today. Our gear is better than what they wore thirty years ago, its better than what they wore ten years ago and we still lose an average of one hundred firefighters every year. I know that not all are dying in structure fires but just one is one too many.

The crew was not prepared for the fire when it suddenly arrived. A wave of fire, heat, and smoke over took them by surprise, Eight of the crew deployed their shelters on the road and the two civilians took shelter with one of the crew members. The squad boss was high above the road in the rock scree watching the fire. He ran down towards the road but couldn’t get there before the fire arrived, He turned around and ran back up the slope were the other four crew members and the crew boss was.

One of the biggest advancement in the last few years through the help and research of NIST has been that of flow paths and fire. NIST has been able to show the fire service that when there is a fire and say a window is knocked out or a door open and not controlled that the flow of natural ventilation would help the fire grow. This growth then fueled the fire to a point that would catch firefighters off guard maybe even kill them. Such fires as the one in Chicago that killed a fire captain that died from the injuries that he sustained while advancing a hose line into a two story, single family structure (Weinschenk, Overholt, Madrzykowski, 2014). Since NIST determined this to be a real threat to firefighters, departments have been taking genuine efforts to control the flow of air to the best of their ability at structure fires. I think that this new tactic of air control has been a real game changer for fire departments all around the

Prescribed fires could be useful to use because it could, reduce future wildfires, it could be excellent for our health and safety, and it could protect animal species.

As the differences between Legacy (circa 1950-1970) and Modern fires (circa 1980-2017) are explored, one must examine and answer a few questions. When is oxidation not combustion? When is combustion not oxidation? What is the basic mechanism of fire spread? How does legacy fires differ from modern fires in fire growth? These questions and the findings associated directly correlate to the study and findings of multiple controlled lab experiments conducted by the Underwriters Laboratories (UL) in 2012. Underwriters Laboratories is a global, non-profit safety organization. UL tests, certifies, verifies, inspects, audits, advises and educates in many markets.

Ansul fire suppression systems use clean agents that quickly vaporize to a gas when used. The product evaporates without leaving a residue behind, and the chemicals are designed not to deplete any ozone and have a small atmospheric lifetime. The FE-36 agent is approved by the Environmental Protection Agency (EPA) for industrial, commercial, and military use via the EPA’s SNAP program that evaluates substitutes for ozone-depleting substances. This product is even safe to use in art galleries.

There was no civilian life at stake but fire fighters soon found themselves in harms way even though there was no

The water supply didn’t help their situation. Although, there was four fire engines that arrived within four minutes within each other and their supply lines were laid out within six minutes, they ran into complications. While Engine 10 & 11 were waiting for the supply lines to be laid out, they started to use the pre-connected hand lines from the tank water but noticed they had no water pressure. Engine 12 and 16 reported that they were having problems due to vehicle traffic running over supply lines. The pressure had to be boosted by both E-12 and E-16 well above the 200 psi working limit of the supply hoses being used in order to accommodate for the friction losses and low water volume. The firemen never established adequate hose lines nor were fire streams deployed. There were not enough water supplies for the size of the fire either. Ladder 5 was not put into operation until the fire had escalated and the additional supply lines that could have been used to fight the beginning fire were not laid out by Engine 11, Ladder 5, and Ladder 4 until the fire was had escalated. The delay in all this added to the fate of the firemen that

The foam consist of a mixture of water, forming agent, and air . As water flows, the foaming agent is mixed and the extinguishing agent is created. With every deluge systems specific purpose and design, it will require foam to have different foam densities. Foam extinguishment consists of cooling the fire and displacing of oxygen. It also suppresses vapors that can be flammable when mixed with air. You will find foam being generally used on class A and B fires. Special designed nozzles need to be in place for foam usage. One type commonly used are foam guns. Foam guns aim to cool fire from a distance. There is also a nozzle that can alternate between foam and water called foam/water jet pipe. You will find these foam nozzle systems in oil refineries, laboratories, and any places with hazardous materials. The use of foam can be of great service due to its ability to flow over practically any surface, can be manipulated to extinguish many different types of hazardous fires. The only downside will be the cost and clean up time required, which tends to be more than other extinguishing

It shall also mean to include thetreatment of buildings components or contents with flameretardant chemicals.
