Furnace Condensate Line Drain

I have run across a condensate line from an oil-fired furnace that drains into a laundry wash basin. My gut tells me that it is not right. I could use some help with an explanation as to why it is not right. Is it a health hazard? Or is it just poor workmanship? Thanks!

Not good but no big deal should have a circle or go up and down so there is a trap to stop air going backward.
