Suggest get a preliminary inquiry done and in case proof emerges of this misconduct, fire him--am sure there must be a clause to this effect under Dismissal Clause in appointment letter.
If such clause does not exist --follow procedure outlined in Standing Order

Dear Colleague,
To proceed against such workman, the aggrieved persons need to make written complaint giving date, time and what racist comments made. After this ,call the worker and confront him with the complaint and hear him out to know his story. Initially, if he is wrong, give mild verbal warning and advise him to refrain from repeating.
If he still continues with it, issue show cause notice, and take strict action after the domestic enquiry.
