This document provides guidance on ladder safety practices for construction based on Washington State regulations. It identifies common causes of falls from ladders as misuse, faulty equipment, or carelessness. Guidelines are presented for proper ladder selection, inspection, setup and use. Ladders must be set up at the proper angle, on stable footing, and not exceeded in weight capacity. Workers must climb facing the ladder with three points of contact. Misuse of ladders, such as overreaching or standing on the top step, increases fall risks. Employers must provide ladder safety training for all workers.
Falls from ladders are a leading cause of serious and fatal injuries in the construction industry.
They PPT are to help you:
Understand the types of ladders used in site ladder requirements.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Construction laddersafety
1. Ladder Safety in Construction
Developed by Division of Occupational Safety and Health
September, 2009
2. Ladder Safety in Construction
Falls from ladders are one of the leading
causes of injuries in the construction trade.
The majority of the falls are caused by misuse,
faulty ladders or carelessness.
The Ladder Safety Rule (WAC 296-876) was
written to reduce or eliminate these mishaps.
This presentation provides some basic safety
practices on ladder use based on these
regulations.
3. Improperly getting on or off the
ladder
Loss of balance
Setting up the ladder improperly
Overreaching while on the
ladder
Mis-stepping or slipping while
climbing or descending
Common causes of ladder injuries
4. Other causes of falls from ladders
Lack of training on safe ladder use
Using the wrong type ladder for the job
Exceeding the ladder weight capacity
Climbing ladder with tools or material in hands
Climbing or descending not facing the ladder
Oil, grease or mud on ladder rungs
Ladder not secure at the base or top
Ladder not set up at the proper angle
Ladder not extended 3 feet above upper surface
Using the top step of a step ladder
Placing ladder on unstable surfaces
Over-reaching beyond the side rails of the ladder
5. Ladder Training
Every employee that uses a
ladder must be trained by a
competent person in the use,
placement and construction of
the ladder and the hazards
associated with them.
A competent person is anyone
who is knowledgeable of the
ladders to be used, can
recognize all the hazards
associated with ladders and
has the authority to take the
necessary action to eliminate
these hazards.
6. These include stepladders and have one or two extra
legs that are attached to the ladder for support. They
do not require a structure to support them.
Self-supporting ladders
Tripod LadderFiberglass stepladder
Wood stepladder Trestle ladder
8. These include straight ladders
and extension ladders. A ladder
is “non-self supporting” type
when it must be leaned against a
solid structure for support and
can’t stand alone.
In the photo, this extension
ladder will be supported by the
building structure.
Leaning extension ladder
against building for support
Non-self supporting ladders
9. Examples of Non Self-Supporting Ladders
Extension ladder Straight ladder
12. Ladder load capacity
Each ladder type has a “duty rating” that is specific
to the maximum safe load capacity of the ladder. A
person's fully clothed weight plus the weight of the
persons tool belt must be less than this duty rating.
Workers should select a ladder based on load
capacity and the type of work to be done.
Exceeding the load capacity may cause the ladder to
collapse.
Ladders will be labeled as shown above.
13. Keep Ladders in a Good Condition
Ensure the following:
- Side rails aren't bent, broken, or split
- Rungs, cleats, or steps aren't bent, broken, or missing
- All bolts and rivets are in place and securely tighten
- Joint between the side rails and the individual rungs/steps is tight
- Safety feet are not excessively worn
- Hardware and fittings are securely attached and working properly
- Ropes aren't frayed or badly worn
- Moveable parts operate freely without binding or excessive play.
- Metal components aren't corroded.
- No other faulty or defective components exist.
- Any auxiliary equipment is securely attached, not excessively
worn and functions properly.
14. Inspect ladders before use
Look for cracks,
splits, dents, bends,
corrosion, and
missing hardware.
All of these ladders are
unsafe and could fail if
used by employees.
15. Mud, Oil or Grease
Keep shoes/boots free of
slippery substances.
Inspect ladder rungs for any
oil, grease, mud or other
slippery substances which
could affect traction.
16. Ladder Positioning
Position ladders so that they are:
Not in the paths of workers walking through,
Not in front of unblocked exits,
Not in front of doors that can open out into the ladder,
Not on boxes, barrels or other unstable surfaces,
On solid footing and level at the bottom,
Stable at the top with each rail supported equally,
Against a structure capable of supporting the intended load,
Away from debris and other hazards.
17. Ladder Placement
Place ladders on solid surfaces
that will support the ladder and
prevent displacement by other
workers.
Block, tape, lock
or guard a door if
the ladder is
placed where the
door will hit it
when opened.
19. Never use the top of a step ladder
step ladder too
short for this job
Warning labels on stepladders clearly state that
the top step and top cap are not to be used as a
step. The higher you are on a step ladder, the
less stable it becomes.
Doing this…. …could lead to this!!
20. Setting up extension ladder
Place ladder base on a firm, level surface with secure footing.
Don’t place a ladder on unstable footing or soft ground.
As the ladder sinks into the ground or slips from where it is
positioned, it becomes very unstable.
Position the ladder
on solid ground or
shoring to ensure
stability.
An unstable base
21. Setting up an extension ladder
When working from an
extension ladder, make
sure it is set up at a 4:1
angle with secure
footing on a firm level
surface.
For accessing an upper
level, make sure the
extension ladder is set
up at a 4:1 angle on a
firm, level surface and
the side rails extend at
least 3’ above the
surface to be accessed.
Lastly, make sure the
extension ladder is
secured at the top and
bottom
Proper ladder set-up Improper ladder set-up
(not 3 ft. above roof line)
22. Proper Extension Ladder Setup
For every four feet of ladder length
measured from where the ladder
contacts the support point, the base
of the ladder should be one foot
away from the supporting structure
(one to four rule).
The ladder must extend at least
three feet above the surface to
provide safe access or be rigidly
secured at the top with a grasping
device if less than three feet.
The ladder in the photo contacts the
supporting structure at 9 feet. This
means that the base of the ladder
should be 27 inches back from the
support.

23. Determining proper ladder setup angle
One way to ensure
proper angle is to stand
with your feet at the
base of the ladder and
extend your arms
straight out. If your
hands just touch, the
ladder will be very close
to the 4 to 1 ratio.
24. Ladder set-up on uneven ground
Ladder can be set up straight and level on just about
any type of uneven surface using ladder levels
attached to the side rails.
25. Straight ladder stabilizers
The straight ladder side rails must be equally
supported at the top, unless the ladder is equipped
with an adequate stabilizer.
Ladders with top stabilizers
26. Climbing or descending a ladder
When climbing a ladder, you must have both hands
free and face the ladder. This allows for three points
of contact with the ladder at all times and reduces the
chances of falling. The three point contact is two
hands and one foot or one hand and two feet.
This way
Not this way
27. Climbing and descending
This worker does not have both
hands free to hold onto the
ladder while climbing or
descending the ladder.
Proper ladder climbing with
tools on belt and both
hands free
29. Electrical Hazards and Ladders
Don’t use metal or conductive ladders near
energized electrical equipment or overhead
power lines.
30. Tying Extension ladders
Don’t tie or fasten ladder sections together to make a
longer ladder, unless the manufacturer specifically
endorses this modification using hardware fittings
designed for that purpose.
31. Ladder misuse
A ladder must be used only for purposes
specifically recommended by the manufacturer.
The ladder in this photo is being as a ramp to
32. Step Ladder Misuse
Rather than a firm, level surface, this
stepladder is positioned on a fence so
the such that the bottom step is
taking the load rather than the side
rails.
It doesn’t extend three feet above the
roof surface, is not secured, and the
worker is standing on the top step to
access roof.
This stepladder is being misused to
access doorway.
Stepladders can’t be used partially
closed and leaned against the wall.
33. Stepladder Misuse
A 3-legged step-
ladder with the
worker standing
on the top cap
and balancing
on one foot.
(Also, no safety
glasses while using a
nail gun and hard hat
is worn backwards)
34. Step ladder misuse
This step ladder is not
fully opened with
spreader bar locked and
the step ladder side rails
are straddling a scaffold
plank being set up in a
position not intended by
the manufacturer.
35. Hazardous Ladder Use
A 3-legged step-ladder
leaned against a 2x4
nailed across the
window.
A repair patch on the
left front side rail of
ladder.
No fall protection in use
while working at height.
36. Hazardous ladder use
Unsecured, folded step-ladder
set on an angled shed roof so
that only the tips of the side
rails lay on roof.
Extension ladder not extended
at least 3-feet above roof, set
up at an angle greater than a
4:1, and it’s not secured top
and bottom to prevent
movement.
No fall protection being used
while on this walking/working
surface.
37. Ladder Misuse
Two workers using two
step-ladders leaned
against wall, set up over
wood debris, with the far
worker standing on the top
step. (also, third worker needs
fall protection)
A better choice in ladders would make this job easier!!
38. More safe ladder practices
Use a ladder only when you are mentally alert and physically able.
Don’t let your belt buckle pass beyond either ladder side rails.
Hold the ladder with one hand while working with the other.
Don't hurry or skip rungs /steps when using the ladder.
Be careful when pushing or pulling anything while up on a ladder.
39. A few more ladder safe practices
Don't test a ladder by jumping on it.
Don't paint a wood ladder.
Don't use any ladder that has been exposed to fire or other strong
chemicals.
Protect ladders from environmental elements such as: excessive
heat or cold.
Don't drop or throw ladders.
Store ladders out of the way of other employees.
Secure ladders firmly when transporting on vehicles.
