The more easily a fuel source accepts oxygen oxidizes , the more flammable it is. Throw hydrogen on your fire, then throw oxygen. Looks like the same effect, must be the same effect. It turns out that these two things do not have the same effect on fire if you look beyond the similar flash of increased energy release. They have a similar result but through completely different mechanisms.

Anyway, back to my conversation about being unable to reduce certain things in nature

Hydrogen affects only the fuel side. Oxygen only affects the oxygen side. If you were to compare the gases being released by the fire before and after you added the oxygen, there would be no difference. All you did was accelerate the process that was already happening. Hydrogen, on the other had adds an extremely receptive fuel source. Hydrogen is so ready to oxidize that it has a hard time existing in its pure state here on Earth. This actually gives us a clue as to WHY water puts out fire.

It is the same reason that carbon dioxide CO 2 is also a pretty good option throwing pure carbon dust on a fire would have a similar, albeit smaller, flare as throwing hydrogen on it. Water puts out fire by creating a barrier between the fuel source and the oxygen source it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor. This smothers the fire.

When the blood vessels under our skin widen, our heart pumps more blood to our skin, which releases more heat from our inner body.

Our bodies are constantly working to hold a steady core temperature around degrees Fahrenheit F. This allows our organs to function properly.

But when the temperature outside is extremely hot, our temperature can start to rise. A person with a body temperature above degrees can develop heat stroke. This can cause dizziness, difficulty breathing, confusion, seizures or loss of consciousness. Brain and heart damage—sometimes permanent—can occur when body temperature climbs above degrees F. Too much summer heat can be unhealthy for everyone, but it can be especially dangerous to firefighters. The incidence of fires increases in the U. Firefighters fight almost twice as many fires in the summer compared to the rest of the year.

On top of dealing with the extreme heat sometimes over degrees F! All of these factors together can place firefighters in immediate danger of heat exhaustion , heatstroke and heart problems. In fact, firefighters are up to times more likely to die of coronary artery or heart disease during or soon after they suppress a fire. It depends on the type of fire.

Not Helpful 7 Helpful The best all rounder is a CO2 extinguisher, since it is a gas-based extinguisher; you need to ventilate the scene after using CO2. Not Helpful 2 Helpful 5. Yes, aim at the base, because then you will extinguish it from the source and it will go out quicker. Not Helpful 3 Helpful 6.
