As both a retired first-responder & a MS owner, I'm uniquely qualified to offer quidelines on how to conduct a visit to you local fire station. Certainly tell them about the tab on the TeslaMotors main page for first responders & that they can navigate to a video. But there's nothing like seeing in the flesh - these folks train constantly & hands-on whenever possible. Once they're convinced that you're not a salesman they will be enthusiastic about fondling your beauty. Try to catch them right after lunch or before dinner because fire companies in urban areas have duties in addition to answering alarms (inspections, maintenance, continuing education at their fire academy, etc).
First locate the station officer. Mention that though Tesla's are rare, they are out there, especially on interstates (last winter metro Atlanta was said to have over 300 owners.) Assuming that you're visiting your local station, bring home the point by telling him which street you live on - there's at least 1 MS in his territory. Mention that the SUV model will be released later this year, on essentially the same platform.
First explain the key fob - what it does & where it's likely to be. Demonstrate the recessed door handles, & how to unlock the car via the touchpad.
Stress that the car is always powered, and that it's totally silent. Explain that the driver's seat is the 'on' button (I tell them it's an asshole detector) and that if the driver's foot is on the brake a rescuer could bump the car into gear even if the driver is unconscious. Show how to put the car in park (after an accident it may not be). Repeat that the car is always powered, and silent.
Next - the batteries. Tell them where both the main battery pack & the 12 volt are. Show all 3 methods of opening the frunk (practice at home so you know where the mechanical release is, & where the secondary latch release is.) Explain that the 12 volt holds a relay closed & that by cutting the labeled wire the main battery pack is isolated from the rest of the car, and that cutting the wire also disables the airbags. Let them open the access panel in the frunk & see the wire. Explain the glycol battery coolant, & that if there's blue fluid or smoke under the car then the battery pack has been compromised. Mention that the high voltage lines are all orange.
Show the charger port, explaining that the light will go out in a minute, but the car may still be charging. Explain that the plug will be locked to the car if the car itself is locked, but if charging at home the wall plug can be removed (and is surely on a dedicated breaker in the panel box).
Show the mechanical releases for the rear doors & the hatch. Show how the rear seats fold down - they will recognize that a backboard will fit through the larger section, for safer extraction of a rear passenger.
Finally, explain that, while the body & most of the frame are aluminum, there is hardened steel behind the rocker panels & the A pillars.
These are the primary points to review for a hands-on. It can be covered in 10-15 minutes, but if the crew has no pressing duties they will likely have questions - try to keep them on topic till you've covered the essentials, then if they're not called away you can answer about performance, charge time & range, & all those things your neighbors also ask about the car. If you cover the basics it's ok to say 'I dunno' to other things.
Again, it's important to have your local rescuers go over the car in the flesh. It will stick with them far better than just seeing a video - it's the difference between seeing a super-model in a commercial or having her as your prom date. Firefighters & EMT's do appreciate power & beauty. The bad news (unless you enjoy showing off your baby) each station will have more than 1 crew on 24 hour shifts - most counties around Atlanta have 3 shifts - so ask about that & try to make visits with each of them.
