 they're widening and cleaning the line as they go. Still working with just the top soil. One dozer, front dozer is pioneering. Second dozer is cleaning. Third dozer is coming in. Make the final finishing touches to it. Just to clean up anything that's left over and to make sure that the line will hold. Dozers will push the material left and right to continue to clean it. Third dozer in the rear will come up and take up any cleanup that's necessary to make the line secure. The downhill push is fairly easy to do other than the massive amount of material that's accumulated sometimes makes it hard to disperse it and keep it clear of the fire burning area. You get a good clean cut into the side. The cropping area, the lower dozers have trouble getting up to where the upper dozer is. They're pushing dirt around. He can get some traction on it. The boulders that you see outcropping is a large one. He gets the track up on it and he can't move. He loses maneuverability and he can't climb over them. So the upper dozer will... Typical of what happens in this type of terrain pulling down like that takes out people and equipment. This type of rock, they've got a piece of equipment like this bulldozer catching it in the side or in the canopy and injuring the people or personnel that work in the general area of it. Block is uncontrollable after you push it with the dozer. Move up to the upper dozer. That's why we have the one dozer left up high as a safety dozer in this situation. Dozers are now stuck. Front dozer will run his cable down and hook on to the middle one and all three of them will try and come out of it together. Pulling the cable up tight to get a good position so that he can pull the second dozer and the second bulldozer or middle bulldozer is hooked to the third one also with a winch line. The two lower dozers are stuck. They can't get over a rock outcropping. Nobody is standing near the cables when this type of operation is taking place because if the cable snaps, the cables can spin out to the left or right and hit people. They've been knowing to cut people in half. Pulling each other. This is a daisy chain operation that takes place sometimes in very loose terrain, such as you see here. The safety is very important and coordination between operators is very important. The situation being that the hose will have to be lifted and carried over top with a bulldozer. Lift it up over top of it. If the bulldozer goes across, the hoser has a very good possibility of cutting it. With firefighting operations, we can't shut the water off and remove the coupling, remove the hose from the area, so what we're going to do is lift the hose up over top of the dozer. We're going to lift the dozer in wildland firefighting. The dozer is lifting the hose up in the air trying to clear the dozer with it. The dozer continues downhill. Hoses put up. This has to be a coordinated effort. Safety is involved here. A lot of safety are because they're walking up on tracks in the area of the bulldozer that are moving. If the dozer starts to move, it can grab a hold of one of the personnel. You see the hose slides back over the dozer. They don't drive over it. Bulldozer operator comes up, picks up some dirt, moves the dirt over, attempts to cover the hose to a point that he can get his tracks over without damaging the fire hose. Get some directions from the firefighters on the sides. Hose is covered. He can continue over the hose, continue on his way. It's ranch with the bulldozer. He's in the middle of a safety zone. When the dozer back and forth, you can see that he's tilt the blade down, putting in a trench. He needs a deep trench in order that he's going to do to build it up so that he can get his dozer in it so that he can get off the dozer and get into the trench underneath the dozer. It's important that he digs down deep, continues moving so that the dozer leaves a hole underneath it that he can get into. Drops the blade has a trench and heavy dirt material on the downside of it. He locks these brakes, takes his helmet off, throttles his dozer off, indicates that he has exited the dozer and that there's an operator clear of it. All dozer operators understand that if they see a dozer with the seat forward that they need to look for the operator. He then clears the dozer and prepares to go under it. The dozer's fire blanket out and goes underneath the dozer with it. He gets underneath the dozer and he covers himself with that blanket. Through a protecting because of all the sheet metal and iron, fire would be coming up from the front of the dozer. The dozer's pointed towards the fire and on an angle, the lower side of that dozer is towards the fire and the berm that he's put on the lower side of the dozer is angled towards the fire. That's his protection, the dirt, the track and the side of the dozer. When the dozer lines in, it's important that we put in water bars to help stabilize the soil and for erosion control. Sometimes when they're operating on a fire line, if we have time we'll put in water bars as we go or after we come back we'll put in water bars. The idea of the water bars is to position it so the water goes off downhill, control soils make it difficult to put in most of the time if they're put in correctly such as this with an open throat the lower end has to be opened up which is called the throat. With that throat open we can continue to control the water. The distance between them on very steep ground is approximately 50 feet between water bars on ground that is very low grade or low percentage of grade but with water bars at 150 feet it's important that we put them in correctly with an open throat back dragging back to get the water to flow into it if at all possible same position, moving it over cutting down, shutting the water off shutting the water off to the left you see, turn, cutting cutting the material lifting the blade and then he runs out to keep the throat open that lower end is important to be open if that throat is closed the water can't flow out the track breaks over shows that the dough can slig around
