Working at Heights

Working at heights is defined as any work performed 1.8 meters or more above the ground. Hazards of working at heights include falls, falling objects, planking or scaffolding failures, and electrocution. The hierarchy of controls recommends avoiding work at heights when possible and using fall prevention methods like guard rails, warning lines, and personal protective equipment when work cannot be avoided. Ladders, mobile elevated work platforms, scaffolding, guard rails, warning lines, and safety harnesses are common equipment used to reduce fall risks when working at heights. Regular inspections of equipment like scaffolding and harnesses are important to ensure safety.

Working at Heights

Mohaimen, Al-Atbee,

Introduction

Most of us work at heights at some stages. We often overlook hazards


because we do not consider simple tasks as climbing a ladder for a quick
job as dangerous. We take chances, believing our abilities are exceptional
or that it will never happen to me!

Work At Height is defined as :

“Any work to be performed at height of 1.8 meters or above from the


ground level where a person is standing, or any job being carried out
below the ground level is classified as work at height ”.

2
Hazards of Working at Heights

 Falls from heights: slips, unsafe access, lack of fall protection.


 Falling objects: falling tools / debris.
 Planking: giving way.
 Collapse : incorrect construction or overloading.
 Electrocution : from overhead power lines.

Ladders

Fixed Access Ladders


• Facilities where access is often required.
• Safer than portable ladders.

Portable Ladders
• Short duration tasks (<15min)/ access.
• Can be unstable.

Mobile Elevated Work Platform (MEWP)

Mobile Elevated Work Platform (MEWP)


Lifts are a better way to reach overhead areas and are safer than ladders. However, there are safety
precautions that must be followed.

Scaffolding

Fixed Scaffolding
Scaffolds should only be erected, altered and
dismantled by personnel who are trained and
hold a certificate of competency.

7
Scaffolding

Fixed Scaffolding
Scaffolds should only be erected, altered and
dismantled by personnel who are trained and
hold a certificate of competency.

Mobile Scaffolding
Mobile scaffolds are a type of supported scaffold
set on wheels or casters (system scaffolds).
Mobile scaffold height is restricted to 8 meters.

8
Scaffolding Inspection

All scaffolding must be inspected before using them and on a weekly basis to ensure
it is safe. The scaffold will have a “Scaff tag” to show its safe. The tag should show:

 Inspection details.
 Intended use.
 Safe working load.

If no tag is present then don’t use the scaffolding.

9
Guard Rails

A guardrail system consists of top, mid-rail, and toe boards.

• Strong enough hold the weight of someone falling into it.

• High enough to prevent falling over (min 1m high).

10
Warning Lines

Warning lines/ barriers keep workers away from unsafe edges, or barrier an area which may be
hazardous due to falling objects.
Placed at least 1.8 meters away from the edge.

11
Personal Protective Equipment (PPE)

 Harness System & Lanyard.


 Hard Hat.
Depending on Task:
 High Visibility Vest – (Recommended).
 Gloves – (Recommended).

Harness System & Lanyard are


designed to stop the fall happening or
to support and hold a person in the
event of a fall. Either:

• Work Positioning (Stop the fall).


• Fall arrest (Prevent hitting the
ground).

12
Safety Harness Inspections

 The user must inspect the harness prior to use.


 Any signs of cuts, tears, abrasion, discoloration or heat damage must be
reported.
 If harness has been in a fall or the label is missing, then it should be taken
out of use immediately.
 If the user is unsure about the harness or its components, then they are to
report to the supervisor.

13
Anchor Points

 Secure.
 Strong enough withstand 2000 Kg.
 Ideally above your head.

Never tie off to an object not designed


or strong enough to be an anchor point:
• Pipes.
• Wood structures.
• Electrical wires.
