What is a good score on the firefighter written exam?
Once your payment is received for your testing fees, you will be emailed an Introductory Test Guide for the written examination. You must score at least 70% on the written examination to be considered “Passing” on this portion of the exam process.
How do I study for the fire exam?
Studying for the Exam To better prepare for the test and guarantee a higher score, you might want to invest in firefighter written exam prep books that overview the format of the test, review some subjects you’ll be evaluated on, and allow you the opportunity to take practice exams to see what the test is really like.
Do firefighters need to know math?
Within the fire service, there are many opportunities to use math. The first one that comes to mind is calculating pump pressure to determine the PSI (pounds per square inch) on the end of a nozzle. Basic math skills, like addition, subtraction, multiplication, and division, are necessary.
What kind of math do firefighters use?
For example, firefighters use simple algebraic expressions (fire dynamics) to help determine the stability of buildings after they have been weighed down with water.
What is the minimum PSI for a fire hydrant?
B. The minimum fire flow from any individual fire hydrant shall be 500 gpm. The minimum flowing pressure at maximum flow shall be 20 psi.
How much PSI is a fire hydrant?
Fire hydrants are flow-tested at a residual pressure of 20 psi; therefore, firefighters should understand the typical flow rates of fire hydrants at that pressure.
What does an orange fire hydrant mean?
500 to 999 gpm
The tops of hydrants are painted in colors to indicate how much flow they can produce in gallons per minute (gpm). Blue – over 1,500 gallons per minute (gpm) Green – 1000 to 1,499 gpm. Orange – 500 to 999 gpm. Red – less than 500 gpm.
What do you pump a standpipe at?
In buildings constructed after 1993, NFPA 14 requires standpipe outlets to flow a minimum of 250 gpm at, as mentioned previously, a minimum pressure of 100 PSI.
