Scott Larson of Stateline Farm Rescue discusses the importance of atmospheric monitoring when attempting a grain bin rescue.
[MUSIC] Welcome to Fire Engineering Training Minutes. My name is Scott Larson, and today we're gonna talk about atmospheric monitoring and in grain bin rescue confined space operations. Any fire department can attempt a grain bin rescue by following a few simple steps. One, is have your rescuers harnessed off and have the safety lines in place. Second is atmospheric monitoring. That is what we are gonna be concentrating on at this portion. Atmospheric monitoring is looking for a clean environment before we can enter. Atmospheric monitoring in in grain bin operations requires either a four or five gas monitor to properly obtain the air quality. We're looking for various items like, oxygen levels, lower explosive limits, carbon monoxide, hydrogen sulfide or any mixture of any type of gas that could be present within the product that is stored in the bins. Before we begin entering the bin, again we have to do air quality testing. First, we're gonna start with the outside of the structure at the highest point possible with a 405 gas monitor. As you can see, he's got the monitor in his hand and he's testing air quality. If we have safe level readings, we're gonna begin to lower the air monitor into the structure at a slow rate. Down to the patient. As we begin to lower the monitor into the structure we're looking for good air quality. Air quality would consist of zero readings of lower explosive limits, hydrogen cyanide, hydrogen sulfide, CO, or any gas that is obtained on the monitor. If we get any bad quality readings on the monitor, such as a high CO level. A high hydrogen sulphide level or any other high levels that are obtained with the particular monitor using, we need to take precautions in order to give fresh air tot he victim. As air quality testing is been taken acre of within the bin, we need to get ventilation in place as soon as possible. We are simply gonna provide fresh air from the outside to the inside to the victim in the bin. Simple as lowering a ventilation fan with a tube to get fresh air as close as possible to the victim. After ventilation has occurred and air monitoring is in safe acceptable limits,. Proper personal can enter the bin. Harnesses such as this class three harness must be worn and all rescuers must be tied off to a secure to prevent any more fall hazard. Next initial step is to fill out a confined space permit, and have all lock out tag out procedures in place before entry. Once entry is made in to bin, you need to get a roll up on the victim as soon as possible to prevent any further. Action of them falling farther into the grain bin. In conclusion, any fire department can initiate a rescue in a grain bin operation. First, lock out, tag out has to be accomplished. Second, ventilation and air monitoring has to occur. Third, a confined space permit should be filled out, prior to entry. Fourth, a class 3 type harness should be placed on the rescuer with fall protection in place. And finally, we need to get a rope to the patient to protect him from any additional engulfment. Thank you for watching Fire Engineering Training Vids. I'm Scott Larsen.
