I am currently on my fifth shift of my first EMT-Basic job. I work for a county doing 911 and transport calls. Invest in some good water proof boots that fit the type of weather, read your text book, buy seconds of your gear for cheap (pen light, pens, shears, watch,) try to see if your provider will allow you to take a emergency driving course if one is available before you start working. This has been my biggest challenge because I cant drive 10-18 traffic and I wont be able to until I complete the course. See if you can volunteer for a ride along to get familiar with the gear they carry and how they operate.
Also ill give you some advice about starting. You may not receive a warm welcome and thats ok. Medics and Intermediates may see you as extra weight and may not be too happy that they are having to "carry" you. Let them know from the get go if you are not comfortable with something and what you are not familiar with. Do anything you can see that needs to be done around the station, never let your medic or intermediate wash the truck at the end of the day unless they insist. Eventually they will see that you arent just bull:censored::censored::censored::censored:ting about your job and open up and show you things that you never heard about in class.
The most important thing is to listen. If a medic or a intermediate takes the time to tell you something and youve heard it before dont say oh yeah I know. Just listen to what they have to say and tips and tricks will come with the basic knowledge.
