 I'm going to be teaching y'all how to react to a chemical or biological hazard attack on station 3. Tasks, react to chemical or biological hazard attack, decon your skin, decon individual equipment. Conditions, you're given a protective mask, individual decon kits, and a tactical environment which chemical weapons have been or may be used by the enemy. Standards, react to a chemical or biological hazard attack without becoming a casualty. Performance steps, don your protective mask when there is a high probability of a chemical attack. Other reasons why you would don your pro mask, a chemical alarm sounds, a positive readings obtained on a detector paper, individuals exhibit symptoms of chemical or biological agent poisoning. If you observe a contamination marker, which you also learn about on Harrison's station, if your supervisor notifies you that you need to don your pro mask, then you don your pro mask. And if you see other personnel around your area wearing their pro mask, then that means that you should wear your pro mask as well. If you observe signs of a chemical or biological attack, you can go ahead and indicate for people to put on their mask. Better safe than sorry. And also if you're responding to the commander's policy of automatic masking procedures, you should most definitely have your mask set up inside your carrier so that it's as easy as possible to take it out and put it on your face as fast as you can. So what most people do is they put the hood of the mask that's on the back, bring it over to the front so that whenever they open their mask carrier with their left hand, take it out with their right. They can just grab that hood from the front because there's a little latch on it and just pull it over their heads and then proceed to tighten the straps on the sides. Whenever you're done putting on your mask, you will give the alarm, right? There's two alarms that you can give, right? If you hear the alarm after you're done putting on your mask, you can yell gas, gas, gas and at the same time give the hand signal for gas, gas, gas, which is this motion right here.
