Head height

288
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #290)

Inverted V (aka teepee) cut: 1st cut – make the cut diagonally to one side, as far down as you can possibly go. Procedure for 2nd cut is:

A
  • Begin back at the top,
  • Stop several inches short of overlapping the 1st cut initially.
  • Cut all the way down on an opposing diagonal,
  • Then come back up to the top & cross fully over original cut
289
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #291)

Inverted V (aka teepee) cut: On 2nd cut, by leaving the small section intact initially, it helps:

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #293)

Making the inverted V (aka teepee) cut is a fast way to get water on the fire, but has limitations. Limitations such as:

A
  • Opening may be too small to allow Ms easy access to advance a line or emergency escape.
  • Provides limited amount of ventilation.
  • If a locked door is located behind gate (common), its difficult to force the door.
292
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #294)

Inverted V (aka teepee) cut: Sometimes, you can expand this cut the width of the portal. If the gate is surface mounted, the remaining sections of slats can be:

A
  • Slid out from the slat above by grasping them below the top cut

295
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #297)

297
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #299)

Recessed doors and doors w/ wind tabs need different style of cut. 3 cut method: location of cuts:

A
  • 1st – as close to edge as possible with max height to min height
  • 2nd – same as 1st on opposite side, within 6 – 8” due to body of saw (same slat!)
  • 3rd – in center, from top of other cuts & downward about 2’
303
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #305)

At times, especially on wide doors, the weight of the hanging sections can bind the slats that support them – making it difficult to remove them. Avoid this by:

A

Making additional short (2’ high) cuts approx. every 5 to 6’

(these sections are easier to pull & the operation can be further assisted by M’s supporting the sagging area on the low side – where slats have already been removed)

304
Q

Ch. 8: Norman – Forcible Entry

Section: Forcing Metal Gates & Roll Up Doors (NC #306)

3 cut method – key point to remember, all cuts must be made through the same slat at the top and bottom. Also helps when removing the slats to:

A

Push in on 1 side, while pulling out on the other.

(Once 1st slat has been pulled out a little using locking pliers or channel locks or driving the claw of a halligan through the sheet metal – the op can be assisted by a M with a flat head axe tapping only slightly more on the back of the slat)
