You sir win one googolplex EMTLife points for correctly spelling HIPAA.
HIPAA is briefly covered in class, and the *"HIPPA" police fear it because they do not understand it. They get the gist of it, but HIPAA is actually a lot more gray and more dynamic than some believe.
I've been called out before for violating HIPAA because I've discussed calls (without including protected health information (PHI)) with other people, because I did a hospital ring down using my personal own phone instead of the one provided to me by my company (even though I cannot recall a time I include PHI in a ring down ever), calling dispatch using my personal own phone instead of the one provided to me by my company, for saying the patient's name to the patient, typing the patient's full name, age (and age group), and gender into an ECG monitor prior to doing a 12-lead, etc.
I recommend reading a summary on HIPAA. I give credit to JPINFV for posting this link awhile ago.

First of all, I just try to use sound judgement and do things in good faith. I identify what is PHI (eg patient's name, address, diagnosis), etc. I identify whether it's useful/necessary to share PHI, and if it's for "treatment, billing, or healthcare operations".
For example, if a dispatcher tells me the patient's address over the radio, it's OK because it's covered by healthcare operations (although we'll attempt to provide PHI privately eg by pager instead of over the radio if possible). If I give a report to the receiving RN providing PHI, it's OK because it's necessary for future treatment and a part of healthcare operations. When I write it down on my PCR, it's OK because it's for billing. At a clinic, the medical assistant may say the patient's full name (first and last name) identify the patient saying that the doctor is ready for them, but it's part of healthcare operations (you could try to start off saying the first name first, but sometimes you need to say the last name too).
I guess technically there are simple ways to violate HIPAA eg sharing PHI in the elevator when others who are not involved in treatment, billing, or healthcare operations are inside the elevator, or making your facesheet or PCR visible on top of your gurney while people are passing by or as you push the gurney.
If you are extremely concerned about it, your company technically shouldn't severely punish you if you notify them. They may have something like an employee hotline, privacy officer, or something. Perhaps discuss with a supervisor your concern and determines ways to prevent this problem in the future. I would love to say that it's better to be pre-emptive, but I know a lot of companies have their finger on the red button unfortunately.
* I intentionally mispelled HIPAA as HIPPA because that's how I imagine the HIPPA police spells it. Since you can spell HIPAA correctly, you more likely know more about HIPAA than 90% of people in healthcare (somewhat rough statistics, but probably accurate, hehe).
