Tonight was Fire Supression training. We began the class by learning how to shut off the electricity, gas, and water utilities in a home. We then learned about the Fire Triangle (heat, fuel, and oxygen). Remove one element and the fire will go out. There are four classes of fire.
- Class A – Ordinary combustable materials such as wood, paper, and other household goods.
- Class B – Combustable Liquids. In most cases, it is the vapers from the liquid that burns.
- Class C – Energized electrical equipment. Remove the electrical source and, if still burning, it will become a Class A fire.
- Class D – Combustable metals. Almost anything ending in “ium.” These require specialized eqtinguishers to put out.
We also discussed the different types of fire extinguishers. Water extinguishers do pretty much what they sound like, spray water on the fire. Dry chemical extinguishers use a chemical, foam like compound, to smuther the flame by removing oxygen. Carbondioxide (CO2) extinguishers also remove the oxygen from the fire (these are not smart in confined spaces, they will remove your oxygen source too).
Then came the practical excersize. We put on all our gear and went outside. The instructors had used cones to mark off a simulated home. There was a burn pan in the simulated kitchen. It would be lit, and we practiced our team tactics for extinguishing the fire. We got to practice as Team Leader, Safety Officer, Primary Attack team (lead, and backup), and Backup Attack Team. The lead instructor through us a couple curves like the primary egress route being blocked and my backup going down necessatiting the backup team coming in to assist.
All in all, it was excellent training and we all learned a lot.
A quick update on the Dispatch situation. I found out that they are going to fill the vacancy from a list of previous applicants. However, our EMA director said the 2nd shift supervisor said I should definitely come in and sit in on a shift. I met him tonight and he said to just call a day or two in advance. It’ll be a good chance to meet the crew, see more of what the job entails, and learn about the hiring / training process.
