How do I get to know someone?

I'm 19 and soon be 20 I've never even got close to get my first kiss not even a date. Now I'm working as an electrician apprentice, which is not really a job to meet new girls. I'd say I'm average looking and definitely not fat.
Do you guys have any ideas on how to get to know someone new? Like talking to someone random on the street, or on the bus? Or helping someone out? I'm honestly out of ideas. and online dating doesn't really work for me.
