Q

ACCORDING TO BOOK 29 CHAPTER 1 VENTILATION OPERATIONS, WHAT IS A 45° CUT…

A

A SERIES OF TWO CUTS. THE FIRST 45° CUT IS MADE WHILE FACING TOWARD OR AWAY FROM ANY EXTERIOR WALL. WHEN YOU HIT A RAFTER “STOP”. MAKE A SECOND CUT PARALLEL OR PERPENDICULAR TO THE EXTERIOR WALL. DETERMINES RAFTER DIRECTION ONLY.

Q

ACCORDING TO BOOK 29 CHAPTER 1 VENTILATION OPERATIONS, WHAT IS A 45° INSPECTION CUT…

A

CUT THROUGH THE ROOF DECKING AT A 45° TOWARD OR AWAY FROM ANY LOAD BEARING WALL. WHEN THE SAW MAKES CONTACT WITH THE RAFTER, ROLL OVER THE RAFTER AND CONTINUE TO CUT FOR APPROXIMATELY 6 TO 10 INCHES. COMPLETE THE CUT BY REMOVING A SMALL TRIANGLE OF DECKING DIRECTLY OVER THE STRUCTURAL MEMBER.
