Explain the difference between fire resistance and flame spread. describe the hazards firefighters should be aware of during the
Kaylis [27]

Fire resistance is where the amount of time that material has withstood a standard fire exposure whereas flame spread is the speed at which a flame spread along the surface of a specific material and is considered as the difference between fire resistance and flame spread.

Fire resistance is the resistance to fire that is for a particular specified time and is under circumstances of standard heat intensity. It will not structurally fail or else allow the transition of heat and also not permit the side away from the fire so as to become hotter than a temperature that is specified well.

Flame spread is described as the surface burning characteristics enhanced by building materials. It is the most tested property of the fire performance of a material.

Firefighters should be aware of the growth and spread of a fire as they face respiratory hazards in emergency situations which include oxygen deficiency,  temperature elevation, smoke as well as toxic atmospheres. This can also affect both the physical and mental effects of the firefighter and would be worse if proper respirator precautions are not followed.

This indicates that firefighters are regularly exposed to certain concentrations of hazardous materials that include carcinogenic products such as carbon monoxide, benzene, sulphur dioxide, hydrogen cyanide, aldehydes as well as particulates.

Where would contour farming and terraces be most likely to be found? a. On flat, expansive grasslands b. In wetlands c. On hilly
lara31 [8.8K]

Answer:

C. On hilly, mountainous farmland.

Explanation:

[] Terrace farming is where the slope is shifted to create a flat area for growing that also provides the ability to catch water.

[] Contour farming means that the fields suit the natural shape of the slope without changing it.

     Both of these farming methods most likely would be found where there are slopes and inclines, the only option providing us with this is "C" which gives us our answer.

Have a nice day!
