METHODOLOGY : Lecture/Discussion-Demonstration
LEARNING OBJECTIVES : At the end of the lesson, the trainees should be able to:
1. identify the 3 categories in mechanical advantage system
correctly;
2. apply the things to consider in constructing Mechanical
Advantage System correctly;
3. discuss the rules in constructing Mechanical Advantage
system correctly
4. enumerate the functions of Prussik cord in mechanical
advantage system accurately

I. INTRODUCTION:
Preparatory Activities
• Opening Prayer
• Introduction of Instructor
• Checking of attendance
• Presentation of the lesson
• Clarification of personal learning
Developmental Activities:
• Introduce and discuss the following specific subject areas, given examples to make
point clear when necessary.
• Categories in Mechanical Advantage System
• Things to consider in constructing Mechanical Advantage System
• Rules for Mechanical Advantage System
• Functions of Prussik cord in Mechanical System
• As small as possible
o Based on the size of the haul team, try to build an MA system as small as
possible for more pulleys create more friction resulting to efficiency loss.
• Maximizes the amount of ground area the haul team can operate.
o This will also minimize the number of re- sets of the haul system. MA
should be clean, not twisted to avoid unwanted friction.

Not all hauling systems are mechanical advantage systems. If the required force equals to the
load force there is no mechanical advantage present.
3. Number of haulers
3 CATEGORIES :
Simple systems - consists of a pulley system that has a single haul connection between
the load and the haul team.
Compound Systems – are those in which one simple system pulling on the haul line of
another simple system.
Complex Systems – the only way to determine its mechanical advantage is by calculating
the tension units. There are usually two or more haul prusiks pulling from opposite
directions.
1. To determine the MA of a Simple System, count the ropes between the anchor and the load or
1+1=2
5. If the pulley closest to the haulers is on the anchor, the pulley is only considered a change
of direction (CD).

As small as possible.
Based on the size of the haul team, try to build an MA system as small as possible for
more pulleys create more friction resulting to efficiency loss.
Maximizes the amount of ground area the haul team can operate.
This will also minimize the number of re-sets of the haul system. MA should be
clean, not twisted to avoid unwanted friction.
When the prusik slips, do not add an additional prusik. Correct the problem.
Tag line offset – offer a means of offsetting the mainline and belay line
by the use of a hand line that is operated below the rescue package.
Should be used only when minor obstacles need to be overcome, or minor adjustments
need to be made in the fall line.
Guiding line offset:
An offset used to change the mainline and belay line by the use of an
adjustable rope that runs through a pulley and tether attached to the
rescue package at the yoke.
Tracking line can offset the main line and belay line by the use of
adjustable rope that runs through a pulley attached to the rescue
package at the yoke.
A method involving three components that evaluates the safe assembly of a rescue system—
METHODOLOGY : Lecture/Discussion-Demonstration
LEARNING OBJECTIVES : At the end of the lesson, the trainees should be able to:
1. Discuss the course overview about Basic Rope Rescue
Training (BRRT)
2. Explain the safety rules in Basic Rope Rescue Training
(BRRT) appropriately
3. Enumerate the incidents that utilizes ropes briefly
4. Given four (4) kinds of ropes, the trainees should be able
to identify the ropes according to its construction, classify
the ropes used in the fire service and enumerate the
factors that lower rope strength correctly.
5. Perform different kinds of knots and improvised
harnesses used in rope rescue properly at a given
amount of time.
6. Given a number of rope rescue equipments, the trainees
should be able to categorize it into hardware or software
and determine its uses.
7. Appreciate the importance of standard safety factor in
rope rescue operations.
