This document discusses work at height safety. It defines work at height as any work performed more than 6 feet above the ground. It provides examples of work at height including construction, maintenance, and scaffolding work. The document outlines several fall hazards and control measures that should be implemented when working at height, such as using fall protection equipment like harnesses and lifelines, installing guardrails and covers over floor openings, following permitting procedures, and providing fall protection training to workers.

1. WORKING AT HEIGHT

2. • “ Working at height is a place from which a
person could be injured by falling from it,
regardless of whether it is above, at or below
ground level’’
• According to OSHA procedure any work being
performed above 1.8 m (6 ft.) from ground is
identify as “Work at Height”
Definition

3. • Roof /Bridge/Ladder works
• Scaffolding works
• External Window cleaning works
• Construction framing/painting works
• Work of Tower cranes , Man basket work
• MEWP’s (Scissor-lift, man-lift, etc.)
• Others (Top of Lorries, Near deep excavation)
Example of Work at Height

4. High Structures:
Any permanent or temporary above ground structures
used by personnel for any purpose during the course of
the construction works.

5. Anchor point:
• A secure point of attachment for lifelines, lanyards or
deceleration (grabbing) devices
• Anchor points for fall arrest must be capable of supporting
5000 pounds(2,267 kg) Independent
Lifeline
Stable Structure
Scaffolding
Structure

6. Full Body Harness:
• The body harness is a 5 point strap system
• Two lanyards and a single integrated shock
absorber
• Designed to distribute shock load/fall arrest
force over the shoulders, thighs, pelvis, waist
and chest
• The D-ring should be positioned on the upper
back centrally between the shoulders
• Lanyard is a fall arrest mechanism which
must be capable to withstand a load of 5000
lbs.
• Flexible line, about 1.8 m in length and at
least 1.25 cm (2 inches) in width.
• One lanyard should always be connected
before your body moved - 100% fall
protection

7. Calculate the Fall Distance
Lanyard:
• Length of Anchorage connector
1.8 m (6 ft.).
• Deceleration/Free Fall Distance
(Shock absorber) 1.1 m (3 1/2
ft)
• Worker Height Displacement
and Stretch of Harness 1.8 m (6
ft.)
• Safety Factor of 0.9 m (3 ft.)
LL + DD + HH + C = 5.6 m
Required fall clearance
distance using typical 1.8 m
lanyard.

8. Lifeline:
• An anchoring wire rope rigged
between two fixed anchorage
points
• Facilitating the movement of
person with his full body harness’s
lanyard or drop line anchored to it
• The lifeline is used when person
has to move horizontally on a long
length.
Horizontal
Lifeline
Vertical Lifeline

9. • Personnel fall from Height
• Material Fall
• Structure Collapse
• Electrocution
• Slip, Trip & Fall
• Poor Access & Egress
Hazards

10. Unsafe Act/Unsafe Condition
No fall protection &
substandard access ladder
Standing on a sub standard
working platform
Working without proper
scaffolding platform
Do not tie knots the
lanyards
Lanyard is missing
Substandard used of
support

11. Unsafe Act/Unsafe Condition

12. Unsafe Act/Unsafe Condition

15. .
A scaffold should be solidly constructed like a permanent structure, even
if it will be used for only a short time. Be sure uprights are uniformly
spaced, plumb, and set on a good foundation. Use mudsills. Use
horizontal or diagonal bracing to give stability. Provide guardrails and toe
boards to help prevent falls. Inspect planking before installation.
Whenever you're on a single-point or a two-point suspended scaffold,
wear your safety gear or equipment. Be sure it's tied to a secure
independent life line. Scaffold
subject to
collapse
due to
loose base
footing.
SCAFFOLDS

16. Depending on their size, cover floor openings or protect them with standard
guard-rails and toe-boards. Also, protect wall openings, except for doorways
and stair-ways through which persons could fall. This protection should be
substantial and secured to prevent displacement.
Access
opening
without
provision of
protection
around the
opening.
Incomplete
grating platform
not provided
with solid
barriers to
protect the
workers from
falling.
FLOOR and EDGE OPENINGS

17. 100 % Tie off should always
be apply if you are working
at height
Always face on the ladder
and implement 3 points of
contact
Temporary hole covers
should provide to all
openings
Proper storage box for
keeping safety harness
Provide safety nets to
prevent falling materials and
objects
Proper anchorage of safety
lanyards
