is used to support rescuers and/or victims during actual incidents or training.
|
page 147
|
|

|

|

Only rope of block creel construction using continuous filament virgin fiber for load-bearing elements is suitable for life safety applications.
|
page 147

|
|
In order to be consider life safety rope it must not...
|
- Must not been visibly damaged
- Not exposed heat, direct flame, or abrasion - Not exposed to liquid, solids, gases, mists, or vapors of any chemical or other material that can deteriorate rope |

|
|
Is natural fiber accepted for life safety?
|
No
|
page 148

|
|
What two types of rope are used in life safety situations?
|
dynamic rope & static rope
|
page 148
|
|
|
dynamic rope
|
are used when falls are a possibility to reduce the shock impact. It is designed for high stretch without breaking. The elasticity is a disadvantage for hauling applications.
|
page 148 & 150
|
|
|
static rope
|
choice for most rescue incidents, as it is design for low stretch without breaking. It is better suited for lowering and raising heavy loads.
|

|
|
The most common type of rope construction are:
|
laid, braided, braid-on-braid, & kernmantle
|
page 150
|
|
|
laid are constructed by
|
twisting yarn together to form stands.
|
page 150
|
|
|
braided are constructed by
|
uniformly intertwining strands of rope together.
|
page 150
|
|
|
braid-on-braid are constructed
|
with both both a braided core and a braided sheath.
|
page 150
|
|
|
kernmantle are constructed by
|
a braided covering or sheath (mantle) over the main load bearing strands (kern).
|
