Cultivate the Press
Sooner or later, the poop'll hit the scoop and go flying in your EMS neighborhood. The Press will jump down your throats.
How about a preemptive strike?
I'm serious here. If you're not generating stories of the work you do, not cultivating local news outlets, not making contacts with specific reporters and educating them, then you're setting yourself up for a long, hard road if negative publicity surfaces. You'll end up having to expend a tremendous amount of effort defending yourself when they place the microscope on you.
If periodically, positive stories are run about the work you do (who has the ideas? YOU do!) then when that bad incident crops up, it will be seen in the context of past coverage. Working with the Press can help you minimize damage control in the future.
And as a hint to the average grunt; don't wait for your company/service to schedule a "controlled" story. Generate an angle yourself, get a reporter on board for a shift and dazzle him/her with the complexities of rendering quality service and the pressures of the work. (It never hurts to have reporters on YOUR side when squabbles crop up between medics and the services that pay them.)
Nowadays, if negative publicity arises, you can link past stories about the company/service together to provide the reader/viewer a more balanced picture immediately.
Know what you can and can't say when a microphone is thrust at your mouth, but you can also generate interest in what you do without violating any protocols.
