You will prepare a post on the premise that a hazardous material leak has occurred in a school building. There are numerous signs on the door, one in particular is a DOT placard of 3318 on the door.
You swing the door open and there is a man passed out on the floor with a very small 1 person fire beside him. You see a Class A extinguisher beside him on the wall.
How would you go forward? Approach this scenario as a hazmat technician. Use everything you have learned in this class to answer this question.
