An idiot i work with mixed bleach with amonia and of course it gassed up and hit him hard. i moved him to fresh air, should he be evaluated?

Yes: The gas released when bleach and ammonia are mixed can be very dangerous. You describe it as "hit him hard", so I would definitely suggest an immediate evaluation.

Yes - if he was ill.: Ammonia + Bleach can produce chloramine gas which is toxic. Exposure can cause irritation of eyes, nose & throat, headache, coughing, shortness of breath, lightheadedness, wheezing, chest pain/ burning, fluid in lungs, muscle weakness, nausea/ vomiting, abdominal pain, pneumonia, & can be fatal.
