GROUND LADDERS
INTRODUCTION
Despite many technological advances in the fire service, one fundamental piece of equipment has not changed much. The ladder remains one of the fire fighter's basic tools,carried on nearly every piece of structural firefighting apparatus.
The portable ladder is one of the most functional, versatile, durable, inexpensive,easy-to-use, and rapidly deployable tools used by fire fighters. No advanced technology cansubstitute for a ladder as a means of rapid, safe vertical access for fire suppression andrescue operations. Every fire fighter must be proficient in the basic skills of working withladders.
STAIR USING
Use the following steps:
a. As a rescue tool.
b. Up and down the building.
c. As a bridge.
d. Move on unsafe ground.
e. Staircase to replace the burning.
f. As a temporary stretcher.
g. To make the frame while the tank.
h. Step ladder.
TYPES OF APPLIANCES
Stairs are divided into several types:
a. Straight Ladder or Single Ladder.
b. Combination Ladder.
c. Extension Ladder.
d. Roof Ladder.
e. Folding Ladder.
f. Pompier Ladder

SAFETY PRECAUTIONS
When using a ladder safety precautions to be observed as the following:

e. Determine the ladder near electrical cables are not upheld.
f. Determine the steps erected on the building at an appropriate angle which isabout 75o or distance of the stairs of the building (work) shall be:
(1) During the test - ¼ of the height of the building (work)Example: Place of work 20 feet. ¼ x 20 = 5 feet
(2) During working hours - 1 / 3 of the height of the workplace.Example: Place of work 30 feet 1 / 3 x 30 = 10 feet
g. Determine the top of the stairs close beside the window with three roundpass threshold window.
h. Determine the proper pawls on round.
i. Before the rise or fall, determine a safe and proper ranking.
j. Use the Leg Lock or ladder belt while working on the stairs.
k. Up to the highest birds before entering through the arrest.
l. Up / down the stairs to the right hand, right foot, left foot left hand same time.
m. Do not climb the stairs to the members of the excess (Overload)
n. Place the right hand position in the longitudinal or shorten the stairs toavoid pinched.
LADDER TEST
Appliances should be tested and examinations to determine it is always beranked the best, safe and can be used. There are three types / how to test conducted asfollows:
a. Test round . Round tested in the following manner:
(1) Extend the ladder and back up to the wall building. Bunch the top for safety.
(2) Start from the top of the legs are divided edge of birds, and createa jump to the bottom of the rounds to the rounds.
(3) Determine the lower (Heel) is guarded by two members before jumpis made.
(4) The two steps in grip strong in the current round jump.
(5) Do not make the jump more than a rounds to avoid tappingstrong in rounds.
(6) Rounds that can not be made the jump, tie a rope and pull thepower of two.
(7) Be alert and cautious when making the leap, it is feared failure

or damage to the rounds will occur.b. Strings Test. How the test is as follows:
(1) Extend the ladder and back up to the building.
(2) The distance of the stairs (Heel) with a building would be 1 / 4 heightplace to work.
(3) Tie the two strings in the middle or section the second step.
(4) Measure the distance the string with the building.
(5) Use the weight of two people on each string.
(6) Measure the length of the string with the building.
(7) If the same size, meaning that the string is in good condition. if thesize is different, meaning that the string is not satisfactory and send to be
repaired or exchanged.Warning : Do not make binding on the round when the test string.
c . Extending Test Line . How to make the test are as follows:
(1) shorten the stairs.
(2) Re-growth steps with strength and weight of two firefighter held at theside of the stairs.
(3) Two firefighters clung to the line extending as low as be.
(4) Extend the ladder to try some rope above.
(5) Once again, two members clung to the line extending as low aspossible.
INSPECTION AND MAINTENANCE
Each step must be made for the benefit of inspection steps under the circumstancestime as follows:
a. When first received.b. Three months.c. Before and after use.d. The time specified or deemed necessary.e. After being sent for repairs (Major Repair).
Need Parts Review . Inspection on parts the following must be done carefully to thesafety of:
a. Sliding section - Determine the independent movement in place.
b. Extending line - No damage to cord or wire, and can move freely inthe pulley.
c. Pawls - Able to work properly.
