coaching beyond the dugout

[quiggley94]

what rules restrict where a manager/coach can coach from?

example: home team dugout is open behind ther fence for access. home team manager is giving orders and encouarging his players from area behind the fence from the dugout to nearly the home side of the back stop(effectively 6ft short of home plate).

another common example: coaches standing outside their dugout in the field (ie: siting on buckets leaning against the dugout fence) how far do you let that go .

thank you for your opinions
