fireblocking basement

can someone put this in simpleton terms for me? i asked my village inspector if fireblocking in the basement is code. this was his reply;



"Fireblocking is required at intersections of walls and drop ceilig also
where perimeter walls meet the floor system, there usually a void on the
back side of the wall".


only 1/2 inch drywall is required and he also said that insulation will work for fireblocking.


thanks gents
