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.

Is Water Wet? If So, What makes it wet, if not what makes it dry?
Monica [59]

Answer:

Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.

Explanation:

For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.

When you put water onto water, it's an addition of water, you don't say it's wet or wetter.

Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.

Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.

So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
