A common survival fire-starter is a block of magnesium!\u00a0 You scrape off shavings add a spark, and they burn hot.<\/li>\n<li>Class K: Cooking oil, e.g., vegetable oil, fats<\/li>\n<\/ul>\n<p>The fuel matters.\u00a0 If you have a class C fire, spraying water on it could actually kill you, or create dangerous, energized puddles, waiting to electrocute whoever steps in them!<\/p>\n<p>One of the biggest causes of fires after an earthquake is a natural gas leak. After an earthquake, shut off your gas, unless you&#8217;re absolutely sure you don&#8217;t have a leak. One way to tell you have a leak is you see the gas meter dials moving when you aren&#8217;t using any gas.<\/p>\n<p>Let&#8217;s say you have a fire in progress.\u00a0 Do you try to put it out?\u00a0 Here are some questions you need answers to:<\/p>\n<ol>\n<li>Do I and my buddy (buddy system!) have the right equipment? (Especially the right type of fire extinguisher.)<\/li>\n<li>Are there any other hazards? (Your safety is Priority 1!)<\/li>\n<li>Is the building structurally damaged?<\/li>\n<li>Can I and my buddy escape?<\/li>\n<li>Can we fight the fire safely?<\/li>\n<\/ol>\n<p>We reviewed types of fire extinguishers and how to use them.\u00a0 They fall into these categories: water, dry chemical, carbon dioxide, and other specialized types. In addition to being rated by the type of fuel on which they should be used, some have another number to indicate the volume of extinguishing agent.<\/p>\n<div>\n<figure id=\"attachment_407\" aria-describedby=\"caption-attachment-407\" style=\"width: 300px\" class=\"wp-caption alignleft\"><a href=\"http:\/\/www.andrewbaze.com\/wparchives\/wp-content\/uploads\/2011\/10\/CERT-firefighting.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-407\" title=\"CERT firefighting\" src=\"http:\/\/www.andrewbaze.com\/wparchives\/wp-content\/uploads\/2011\/10\/CERT-firefighting-300x235.png\" alt=\"\" width=\"300\" height=\"235\" \/><\/a><figcaption id=\"caption-attachment-407\" class=\"wp-caption-text\">A CERT Firefighting team in action<\/figcaption><\/figure>\n<dl id=\"attachment_150\">We go to use them!\u00a0 The nice part is that we knew what the fuel was (liquid) and had a bunch of fire extinguishers ready.\u00a0 We practiced using the buddy system, had on our safety gear, and used the PASS system, Pull (the pin), Aim, Squeeze, Sweep.\u00a0 The only parts that may not be intuitive are #1 &#8211; pulling that pin in the first place.\u00a0 Sometimes people forget to do that in the stress of being near open flame. The other part is the &#8220;sweep&#8221; part.\u00a0 You will need to aim at the base of the fire (not necessarily the biggest part of the flames, which is where you may intuitively want to aim) and move the fire extinguisher back and forth along the base of the fire, to ensure you covering it fully.<\/dl>\n<\/div>\n<p>We continued to put out fires, until everyone got a chance to put out at least one.\u00a0 The picture gives you some of an idea of what it looked like.\u00a0 It was dark and a bit rainy, but the flames were big and we were able to put them out.\u00a0 It was fun, and a new experience for most of us.<\/p>\n<p>Reading this is not the same as taking a CERT course and fighting a real fire with a real fire extinguisher.<\/p>\n<p>Go take a CERT course! \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On our 6th day of CERT class, we reviewed fire safety and learned how to effectively use a fire extinguisher to put out a real fire.
