Each crew member should have a high level of situational awareness before entering a burning building. For example, firefighters need to be able to read fire behavior indicators, understand the crews tactical assessment, know probable emergency escape routes, know forcible entry requirements, identify hazards, and verify that radios and properly working. When containing fires, firefighters also need to remember vital aspects like gas cooling is not a fire extinguishment method but rather a way of reducing the hazards presented by the hot gas layer or that the most effective use of water on free-burning fires is made with direct attack on the fire. If a firefighter cannot directly attack a fire due to intense heat inside of the structure, it can be indirectly attacked outside through a window or
Convection, heat transfer in fluids (Liquids and Gases) is due to rising currents of fluid due to decrease in Density. Cooler fluid moves in to replace the rising current of fluid. This too, is heated and rises and a circulatory motion is set up within the Fluid. Radiation, the slowest of the Heat Transfer processes will only heat substances 'or bodies" in the direct path of the Heat Rays. Stand in front of a fire on a cold night.
(1) Sickness & Diarrhoea (2) Burns and Scalds. (3) Fractures ands Suspected Fractures. (D5) EXPLAIN THE PROCEDURE TO BE FOLLOWEDIN THE EVENT OF AN ACCIDENT OR SUDDEN ILLNESS. (1) Get help as soon as possible example emergency services apply first aid training only if you got it. Make sure the client is as comfortable as can be staff should also protect themself complete accidents or sickness illness form log information in client file and inform seniority/manager of the incident.
Viscosity can be affected by three main factors, Firstly, the higher the temperature, the lower the density of the magma, causing it to flow more easily. Secondly, the greater the amount of dissolved gases in the magma, the less viscous it will be, and lastly the higher the silica content, the more viscous it will be. Thicker, more viscous magma has a greater potential for explosive eruptions and therefore represent the greatest potential hazards. The thickest type of magma is known as Acidic Magma. Its relatively low temperature, high silica content and leads to blockages and powerful eruptions.
Is it possible to use the Table of Placards in the ERG to find the correct Guide for this incident? YES IT IS POSSIBLE BECAUSE THE I.D NUMBER ON THE PLACARD WILL LEAD TO THE GUIDE NUMBER. What is the primary hazard of material covered by this Guide? WILL ACCELERATE BURNING WHEN INVOLVED IN FIRE.SOME MAY DECOMPOSE EXPLOSIVELY WHEN HEATED OR INVOLVED IN A FIRE.MAY EXPLODE FROM HEAT OR CONTAMINATION.SOME WILL REACT EXPLOSIVELY WITH HYDROCARBONS (FUEL).MAY IGNITE COMBUSTIBLES (WOOD,PAPER,OIL,CLOTHING,ETC. ).CONTAINERS
The energy in the radiator is transferred to the air. Explain the factors that affect the rate of energy transfer in the engine and radiator. • The rate of energy transfer depends on the temperature difference between the system and the surroundings • Bigger the temperature differences between the radiator and the air, faster the rate of energy transfer. • Radiator contains water which has a very high specific heat capacity. So it can absorb a large amount of heat from the engine • Both the radiator and engines are made of metal which makes both of them good conductors of heat.
Class E doors are similar to Class D doors, being classified as openings in exterior walls subject to moderate or light fire exposure from outside the building. Fire doors often contain fire windows. Fire windows are made of wired glass, which allows the glass to withstand high temperatures without breaking. Sometimes fire glass is available without wire, and in
Computer monitors 1 Monitors must be at an angle to avoid eye strain and headaches and in need provide ant- glare screens. Project 1 In the event of a serious injury I would do the following: • Phone 000. • Explain what has happened and answer all their questions in a calm and clear manner so as not to waste time repeating myself. • Ensure there is a clear pathway for the ambulance service. If the address is not clearly visible for the ambulance give them a land mark or send someone outside to wait for them and show them in.
During the process of fighting fires there is alot to be aware of such as thick smoke. Smoke entering your lungs can be a huge risk when it comes to your cardiovascular health. However each firefighter is given a face mask to help you to breathe and protect your lungs from the smoke. How protective are these masks? Alot of the masks contain center ventilation orifice allowing easy air exchange and helps prevent buildup of CO2(the thick smoke created by fire).
If temperature is higher, it leads to blistering. If temperature is low, soft spot can be formed. Temperature also plays important role to improve coating efficiency. 2. Humidity: Humidity in the inlet air should be as minimum as possible and dehumidified air should be used for faster drying rate because the rate of drying increases as the humidity of inlet air decreases.
