2 Math in the Fire Service Using math is a very practical operation that we rely on. Everyone uses some type of math on a daily basis and don't even realize it. When you go into a store and shop you are using math by either figuring out a discount, what your total is, or if using cash making sure to give enough cash to cover your purchase and how much change you should get back. In the fire service math can be used pretty frequently on the scene of an incident. When laying a hose from the hydrant to the scene, we are calculating to make sure we have enough hose to reach, deploying an attack line in the structure making sure there is enough hose, and when making sure we are flowing enough water for the incident by calculating the pressures needed and gallons per minute needed. The purpose of this paper is to discuss my academic and practical applications of math, and the key takeaway from the review of Appendix A. Literature Review During high school I was placed in advanced placement math classes due to doing so well in the normal math classes. After graduating from high school I obtained my Associates in Criminal Justice where I had to take a statistics math class and then with the process of obtaining my Associates of Fire Science, I was required to take Quantitative Reasoning math. My experience working with math in the practical application occurs daily I my job along with at times using it in the fire service . Working as a correctional officer I used just your basic math on a daily basis when having to figure out how much contraband an inmate had on them. I am also a part of our Special Response Team and will have to at times figure out the square feet and volume of a room and then will determine how much chemical munitions will need to be deployed in that area to effectively cover the area. In the fire service math is used to figure out how much pressure you need to provide the correct amount of water for the situation, and getting the correct ratio with using a CAF system. Appendix A was a very good review of all the math that can and will be used in the fire service on the fire ground. The key takeaway I got from the

3 appendix A was the refresher on the correct may to use the order of operation and that if not done correctly it will not give the correct answer needed. Conclusion Math will always be used on a daily basis by almost everyone. The fire service will always require some form of math that needs completed on an emergency scene to figure out the proper flow, pressure, water needed, and if a truck is equipped with a CAF system then you will need to know the correct percentage of foam, compressed air and water for the mixture to be effected. In a lot of emergency cases on a scene most firefighters don't think about using math but instead will guess, so times this may work and sometimes it may not.

4 Answer the Following Question 1. 95 + 72 167 2. 2789 -1453 1336 3. 84 *29 756 1680 2436 First you would take 9*4 = 36, place the 6 under the line , carry the 3 over above the 8, then multiply 8*9=72 + 3 = 75, so the first set of multiplication would give a total of 756. Then place a 0 below the 6, multiply 2*4=8, place the 8 under the 5, then multiply 2*8= 16, place 16 beside the 8, then add both lines together to get the answer of 2,436. 4. (2+3)*(4+5)= 5 * 9 = 45 5. 792/132= 6 792 divided by 132, you will check to see how many times 132 will go into 792 by multiplying 132 by a single number, when checked 132 will go into 792 6 times. 6. 5 2 = 5*5= 25 7. √ ❑ = 12 Need to figure out what whole number times itself would equal 144, when checking the whole numbers 12*/12=144. 8. Solve the volume Length = 4 ft. Width = 5 ft. Height = 20 ft. Volume = Length * Width * Height/ V= L*W*H= Volume = 4 * 5 * 20 = = 20 * 20 = Volume = 400 ft 3 9. Solve for Inches 12 ft. = inches 12 * 12= 144 inches
