NFPA 1006 - 2017 edition
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
Definitions• Low angle rescue – More than half of the weight
is supported by the ground (floor, beam, structure, etc.)
• High angle rescue – More than half of the weight is supported by the rope system.
10
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
Definitions• Vertical rescue – The movement is at right
angles to the horizon. All the weight is supported by the rope system.
• Slope rescue – There is continual contact with the ground, usually low angle rescue, but could include some high angle.
11
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
Why Use Rope?• Areas inaccessible to ladder trucks, or height
greater than a ladder truck’s aerial device. • The need to raise a person from an excavation,
trench, construction site, or other rescue scenes.
12
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY13
Size Up A Rescue Incident• What type of incident is it? • Rescue vs. Recovery Mode • How many victims? Location? • Witnesses • Scope and Magnitude • Additional Resources • Incident action plan • Risk Benefit Analysis

Most Dangerous Point
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY22
Patient Care
• Follow local EMS protocols… • How long for EMS to arrive? • Level of EMS? • FF/EMT? • Consider - “Suspension Trauma” • Still dealing with the Golden Hour
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY23
EMS• Access - how to approach to the victim? • Assess - protection from airborne and blood
borne pathogens delivering basic first aid • Stabilize – basic first aid or EMS level
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
EMS• Package - securing a victim in a
transfer device, with regard to existing and potential injuries or illness, so as to prevent further harm during movement.
• Transfer victims - given local medical protocols, so all pertinent information is passed from rescuer to EMS, and the victim can be transported to a medical care facility”

ALL ABOUT ROPE
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
ROPE PROPERTIES
Different combinations make one kind of rope more suitable than another for rescue operations. Rescuers must determine the material a rope is made of and the way it is constructed.
44
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY
FIBERS USED TO MAKE ROPESNylon • About 10% stronger than polyester • Good shock loading capability • Loses approximately 10-15% when wet (will
regain the strength back when dry) • Susceptible to certain strong acids

Main LineThis rope carries the weight of and controls the load during rappelling, lowering, and hauling operations
Load: The total weight of persons and equipment being lowered or raised on a rope system
Proof load the main line system before putting a life load on the system
RHODEISLANDFIREACADEMY-OFFICIALUSEONLY88
Belay The second rope in the two rope system
This rope is our safety. It is in place in the event of a failure in the Main Line or any components of the main line system
