In this article the title ends with the verb in the Te-Form. Why is this or what is intended here? I don't think I have seen a sentence end with the Te-form before
エアコンや扇風機を使う季節 火事に気をつけて
My Translation: Its the time of year to use air conditioning and electric fans. Be careful of fires.
Your translation is spot on.
There is absolutely no problem ending a sentence with a verb in the te-form. It is done quite commonly. This is, of course, more direct than adding ください or ね to the ending, so in conversation it has the possibility of sounding pushy, but not necessarily in a broadcast, etc.. If you are addressing someone in a higher social position who you should show deference and politeness to, this type of directness should probably be avoided.

気をつけてくださいね ⇒ 気をつけてください ⇒ 気をつけてね ⇒ 気をつけて
気を付けて is a phrase that is so commonly used, that it rarely used in anything but the -て form of the verb. (It has listings in jisho.org and my pocket dictionary.)
I understand this to be more of a public service announcement than as an article title (though it does function as both). The feel is more of that of a friendly reminder, especially because they are talking about statistics for a portion of the article.
