TSA Security Check - Flammable vs. Non-Flammable Aerosol

I plan on flying domestically in the US tomorrow, and I was wondering if it is possible for the TSA to tell the difference between flammable and non-flammable aerosols as they go through a security scanner. Obviously they can determine if it is flammable when doing a bag search, but if it is only through a regular security scanner, are they able to determine if my deodorant is flammable or not?

Also, if my deodorant bottle is 3.5oz, what is the chance that I get caught for breaking the 3-1-1 rule?
