Fire apparatus

It is well known that fire fighters expose themselves to many hazards, from toxic gases, structural collapse, to fire and extreme heat. They don’t do it for glory but for the desire to help protect property and the people in their community. To help minimize risk to their health and safety, fire fighters use and carry protective equipment and wear specialized protective clothing, known as PPE. The Personal Protective Equipment (PPE) and the fire truck and equipment it carries has evolved drastically from the first fire fighters to now. The original fire fighter helmet was made up of leather and had long brims coming down the back and both sides of the helmet. The brims would curl to help avoid water from getting inside the coat and on…

handled by the Chicago Fire Department. The incident involved a gasoline tanker that struck a dumpster and started to lose product, which then ignited. This paper will also discuss gasoline, as it was the primary fuel involved with this scene. Time will be spent looking at gasoline to understand its characteristics and determine if the fire department used the correct suppressant and tactics for this call. The Chicago Fire Department used water and foam on this fire, so this paper will…

covers the organelle and contain its skin as the inner membrane folds over many times and create layered structures. The energy made is called ATP. ATP stands for adenosine triphosphate. It’s a single nucleotide with two extra energy storing phosphate groups. When food molecules are broken down inside cells, some of the energy in the molecules is stored temporarily in ATP. Cells need a steady supply of ATP to function. The Golgi apparatus helps the cell maintain homeostasis by modifying,…

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate…

dangers of firefighting do not end when the fire is put out, during the final steps of a call, firefighters are exposed to long term health dangers during a period called overhaul. Overhaul is a safety procedure performed by firefighters after the initial fire is put out, in order to look for hot embers in walls, ceilings, and other areas. The goal of the overhaul is to eliminate the possibility of a respark, starting the fire again. The danger of overhaul come in the form of harmful chemicals…

to the intensions of early firefighting. In ancient Rome the first Fire brigade was established as a form of income. Fire brigades would respond to alarms but would not do anything about the situation until a deal was made with the owner of the residence. If a deal was not made the structure would burn to the ground. Over time firefighting has gone from a selfishly profitable scheme, to an organization filled with people who want to help the people of their community any way they can. The…

Eukaryotic cells are cells whose nucleus is bound by a membrane; these cells contain organelles, which are structures each enclosed within its own membrane found only in eukaryotic cells, each organelle has a specific function inside a cell. One type of organelle is a lysosome, which are the organelles that dispose of waste and toxins. Lysosomes are fluid filled sacks which range in size from 0.1 to 1.2 micrometres and contain around fifty degradative enzymes that enable it to effectively…

Introduction Fire investigation includes the scrutiny of every fire-related incident once the fire is extinguished by the firefighters. The practice of fire scene examination is related to the inspection of a crime scene and like any other crime scene, the fire scene must also be preserved and the evidences are collected and analyzed; however, it involves several additional dangers and difficulties. The investigation will include close survey of the damaged scene in order to establish the source…

Fire Behaviour Moisture: Background Information: With some parts of Australia being extremely prone to bushfires, ways to prevent them and understand them are vital. They can be caused by unattended fires, glass, cigarettes and flammable chemicals left in the sun. (Bushfires - Get the Facts, 2008) Fires account for approxmately 100 deaths and 3000 injuries every year. (BrianAshe, 2012) The total cost of structural damage estimates around $18 billion and $16 billion devoted to managing the…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…
