Exception tables

Hello, would i make a exception table, it would be for a Touched event because it spawns parts on my that have the touched in them? I need the table to keep them from harming me.

local whitelist = 
{
	Part = true;
	Brick01 = true;
	Handle = true;
}

script.Parent.Touched:connect(function(hit)
	if not whitelist[hit.Name] and not whitelist[hit.ClassName] then
		print("ok")
	else
		print("no")
	end
end)
