Q

Large Frontage building?

A

OVER 30 feet
-no condition or victims showing- place center of the turntable approx. 15 feet from the side wall passed on your approach

this allows for:

  • easy forward movement for less experienced member (tiller FF should leaves wheels lined up with tractor)
  • more clear frontage for BACKSTRETCH
  • backing up would be impractical/time consuming

Q

Venting with Aerial Ladder…

A
  • aim at upper window panels, just above sash, and extend WITHOUT t hitting the sides or tops of window frames
