Precis Study Flashcards
Definition: Water Hammer
The term used to describe the destructive forces, evident in pounding noises and vibrations, which develop in a piping system when a column of non-compressible liquid flowing through a pipe line at a given pressure and velocity is stopped abruptly.
Definition: Forcible Entry
The act of gaining access to a structure through means other than an open window or door using applied techniques and available tools which aid in reducing unnecessary damage to the occupancy or compromising structural integrity.
Definition: Salvage
Consists of those methods and operating procedures allied to firefighting which aid in reducing forcible entry, fire, water, and smoke damage during and after fires.
Definition: Overhaul
The search for and extinguishment of hidden or remaining fires; placing the building, its contents and the fire area in a safe condition; possibly determining the origin/cause of the fire and recognizing and preserving and evidence of arson.
