the fire engine wasn't just a publicity stunt we may need their protection in some of the experiments with flammable liquids the foam tonight friends from a rancher and power we get from petroleum products petroleum he home cooks who develops power for good soil conservation practices it lubricates tractors cars trucks machinery yes petroleum is our friend but if we carelessly all misuse of power for using petroleum products safely is simply a as i know the sign is burning and i'll tell you why students has to be handled in a particular way if we have to get the benefit of it and not harm ourselves or our belongings first let's see how some products act let's take the most common one gasoline something we use every day gasoline seems to vary and doesn't it nevertheless gasoline itself does not gasoline which burns that's true of all petroleum products in fact of all combustible materials even coal and wood actually burn the vapors given off by these materials at certain temperatures the fact that gasoline vapors burn rapidly is very valuable this rapid burning is what makes your car run and your tractor work but it can also present certain hazards turn on the  this is how you look when you forgive them one container to one right but don't watch him watch a shadow that's what burns those papers you see what happens when you call gasoline from a container tank barrel you see why us or a flame can cause a fire now you can understand why the so called empty gasoline barrel is dangerous to liquid gasoline or takes something you do pretty often although you'll probably never seen this view of it refueling the tractor you see how those vapors pull down over the engine all they need to set them off is just one little spot that's why the tractor engine must always be shut off and allowed to cool before refueling doesn't know where the tank alone that much or not look at that he could have avoided that by measuring his tank if you measure your tank you'll know whether it will hold that much  incidentally if you ever do overflow your tank wait five or ten minutes for the gasoline to a baffle rate before you start the engine we've been talking about gasoline but the same things apply to any or they were burned so by using the right temperature in each case we could repeat our experiments with any petroleum product to put this whole matter  air plus ignition temperature equals fire these three elements of fire whenever the right amount of vapor and there a mix at ignition temperature there will be a fire we can hasten this mixture of bait for an air by breaking up a petroleum product into small particles then tiny particles will vaporize rapidly frames i want you to think of your own five think of how you and the members of your family storing handling and using petroleum products storing gasoline safely either in underground tanks like this already in above ground tanks which are located a safe distance away from buildings different state codes require different distances from tank to nearest building but national fire prevention authorities say that a distance of at least forty feet from the nearest structure of any kind is needed for safety you keep gasoline kerosene in approved containers red container for gasoline clearly marked gasoline green containers a kerosene clearly marked with the word kerosene and do both containers have spring covers so that the liquid will not spell release vapors never a small when your near gasoline or tractor few remember those vapors don't use gasoline for cleaning clothes use a special cleaning fluid and go outdoors to do your cleaning so the vapors cannot collect in dangerous amounts of drollery in products of the basis of modern farming and modern from life when we use them correctly and for the purpose for which they are made the products of petroleum best and most valuable service but it is up to you it's up to each of you individually to answer the question will petroleum be your servant or your destroyer the answer depends upon how carefully you handle petroleum products and on whether you use them only for the purposes for which they were made you know that in one year five hundred thirty six people were killed in fires that started because somebody threw kerosene or tractor fuel into a stole to get a fire going quickly kerosene vaporizes almost instantly in the presence of heat it doesn't need a fire to a red hot great fire box will do it watch how kerosene vaporizes on this wall metal plate blame it on the bathing suit now what usually happens when there's an explosion like that is of the person drops on throws the container in that way more kerosene is thrown on the fire on them and all over and the fire spreads that much more never use petroleum products starting bringing up fires friends many of you know that it was a fire caused by the careless handling of kerosene which led to the organization of a from safety committee community gym where you come up now all right jim well ladies and gentlemen we had a fire at our house a bad one it started with throwing kerosene on the stove but i'll tell you that in just a minute but first i want to say a few words especially to you young people they say that we're a bit careless sometimes well maybe we are but we've got a lot of living to do and sometimes we're in a hurry to get at it but it's tough to do much living if you're badly burned or crippled and it's impossible to do any live if you're dead fellows and girls young people ought to be the most careful people of all why well because we've got the most to lose we've got our whole lives ahead of us and we've got the whole thing to enjoy we want to make farming the best occupation in the whole world and it can't be that until it's safe safe for you safe for me and safe for our families and for the families we're going to have when you older folks i don't mean to leave you out or anything we've got to stick together well it was five months ago yesterday that we had that fire and mom still in and out of the hospital it'll take lots and lots of operations before she is well again to i wasn't home when the fire started i spent the night over at my uncle's and the next morning when i was on my way home the fire engine came along i guess dad had made the fire in the morning as usual and went out to do is morning chores
