could be injured if they fell from that place
Any work at height of 1.8 meter or more
from the ground level or floor.
Work there is a risk of a fall liable to cause
Personal injury.
5. Risk Assessment
Examples of what to consider include:
• The work activity
• Equipment to be used
• Location of the work and any hazards
• Working environment (weather, lighting)
• Condition of existing work surfaces
• Duration of the work
• Physical capabilities of workers
6. Organization, Planning, Competence
The Law Work at Height Regulations 2005
Work at height should be:
• Properly planned
• Appropriately supervised
• Not carried out if weather conditions jeopardize health and
safety
• Buddy System
Those working at height should be:
• Competent or if being trained
• Supervised by a competent person
• Choose right equipment to-
PREVENT FALLS, REDUCE INJURY
Don’t chance it---
8. Hazards
• Falling from Height
• Fall of material & equipment
• Poorly maintained access
• Vertical distance
• Roofs
• Deterioration of material
• Unprotected edges /opening
• Weather condition
• Unwanted or loose materials
9. Precautions

11. The Regulations Hierarchy
AVOID work at height if you can
PREVENT falls by using the proper gear, such as scaffolds or cherry pickers
MINIMISE the chances of being hurt if you fall
Applies even to small, quick jobs
Doing nothing is dangerous and illegal
12. Select the right gear
Think about
• Where you are going to be working (ground conditions, space, public)
• How far you could fall and how likely you are to be injured
• How long will the job take and how often will it need to be done
• What you need to do to rescue someone should they fall
• Can the building or scaffold etc take the weight
of the workforce and materials need for the job
• Is it the best piece of kit for the job
13. Prevent Falls
• Use an existing or ‘safe’ place of work where
no additional measures are required
• Use working platforms with guardrails or
powered access platforms
15. Other things to think about
Prevent tools and materials falling:
Throwing materials or debris (bombing) never acceptable
Warn employees about danger areas
You need to make sure that equipment such as scaffolds are checked
After assembly or installation
At suitable intervals or after exceptional circumstances
Scaffold and tower scaffold inspection in each new position and then every 7
days
MEWP on site within previous 7 days
16. Main Cause of Accidents
• Poor Scaffolding condition (BS 1139)
• Bad House keeping
• Lack of knowledge about work at height procedure
• Use of jugad
• Without use of PPE’s
• Without use Fall protection systems
1910.140
• Poor Health condition (Acrophobia)
17. Example of Work at Height

(Requires PTW, TRA, WMS)
• Working on roof
• Working on ladders
• Working on ground level adjacent of open excavation
• Mobile Elevated Working Platform (MEWP)
• Tanks
18. The Roof:
A Risky Place To Be Before Working on Roofs:-
• Fragile materials should be identified
and precautions decided
• Roof edge barriers (or scaffolds) must
be erected to prevent people and materials
falling

above the stepping-off point and must be
secured
• Where access ladders rise above 9 meters
a safe intermediate platform must be provided
19. The Roof:
A Risky Place To Be Before Working on Roofs:-

and toe boards must be erected

must be anticipated, and suitable precautions taken
• Wet windy or Icy weather can seriously affect safety
• Sheet materials including asbestos cement or skylights Will
not support weight
• Walking the bolts not acceptable
20. Scaffolds
