1. PowerPoint presentation
Unit 201: Health safety and welfare in construction
Know about access equipment and working at heights, and how to work with electrical equipment

2. Objectives By the end of this session you will be able to:
Identify legislation relating to working at heights
Identify types of access equipment
State safe methods of working with access equipment
Identify dangers of working at height
State precautions to take to avoids risk to self and others when working with electrical equipment
Identify voltage and voltage colour coding that are used in the workplace
State methods of storing electrical equipment

3. Legislation relating to working at heights
The Working at Height Regulations 2005 (WAHR)
The Regulations apply to all work at height where there is a risk of a fall liable to cause personal injury.
This legislation places a legal duty on everyone for the welfare of employers, employees and managers
There is a simple hierarchy for managing and selecting equipment for work at height. Duty holders must:
Avoid work at height where they can;
Use work equipment or other measures to prevent falls where they cannot avoid working at height; and
Where they cannot eliminate the risk of a fall, use work equipment or other measures to minimise the distance and consequences of a fall should one occur.

4. Working at height The Statistics
Falls are the biggest cause of workplace fatalities
35 fatal incidents in 2008/09 and a total of 421 since 2001
Cause of 4589 major injuries 2008/09
87% of all major injuries are caused by ‘low falls’ (i.e. below 2 metres)
Where work has to be carried out at height, then the duty holder shall take suitable and sufficient measures to prevent, so far as is reasonably practicable, any person falling a distance liable to cause personal injury’ (WAHR)
REMEMBER that injury can occur from a fall of any height, not just from above 2 metres.
Look at the video on working at heights make notes:

5. Working at heights
What are the six steps to safety when considering working at height?
Using activity sheet 13 in groups identify the six steps to safety in the previous video.
What are the steps ? What do they mean?

6. Types of Access Equipment
Trestles
Mobile towers
Ladders
Steps
Hop ups
Tubular
Scissor lift
Cherry picker

7. Ladders
Every year an average of 14 people die and a further 1200 are seriously injured at work as a result of falling from a leaning ladder or stepladder.
Some of these accidnets will be a result of bad planning or use of the wrong piece of equipment for the job.
What are the reasons people fall from leaning ladders and stepladders?
The leaning ladder slipping either at the top or bottom;
The leaning ladder flipping over or coming away at the top;
overstretching;
A fault with the ladder;
Slipping or loosing your footing;
Stepladder wobbles due to missing feet or not being correctly open;
Stepladder being used side-on to the work task.

8. Ladders
Positioning a leaning ladder safely - Ladder showing correct 1 in 4 angle (Securing omitted for clarity).
Positioning a leaning ladder with a side slope - Ladder showing maximum angle at 16° on a side slope.
Positioning a leaning ladder with a back slope - Ladder showing maximum angle at 6° on a back slope.
Ladder tied at top
stiles (correct for working on,
not for access

9. Ladders
Incorrect - overreaching and not maintaining three points of contact
Correct - user maintaining three points of contact
Incorrect - steps
side-on to work activity
Correct - steps
facing work activity
A ladder should lean at an angle of 75º, i.e. one unit out for every four units up

10. Trestles / Hop-ups
Trestle scaffold should always be erected on firm, level ground and with a minimum working platform width of 450mm
Lockable steel hinges and anti-slip feet. Ideal for low level access, painting, plastering
Premium quality steel mobile steps for easy step-up access in the workplace.

11. Mobile Tower Watch the short video clip
HSE key messages are that:
you must be competent in erection and dismantling of mobile scaffolds; and
you must always read and follow the manufacturer's instruction manual and on no account attempt use the equipment beyond its limitations.

12. Mobile Tower
Commonly referred to as mobile access towers or mobile scaffold towers, these structures are manufactured from prefabricated components where the principal structural materials are aluminium alloys or fibreglass.
Wheels or feet of the tower must be in contact with a firm surface. Outriggers should be deployed as specified by the manufacturer.
Mobile Access Towers are covered by PASMA. More Information

13. Spot the hazards
In groups list the hazards you can see compare findings with the class

14. Mobile elevating work platforms (MEWPs)
Take a look at this scene. Do you see a hive of safe activity? Or a high risk high street that's about to come crashing down? Mobile elevating work platforms (MEWPs) can provide a safe way of working at height.
They:
allow the worker to reach the task quickly and easily
have guard rails and toe boards which prevent a person falling
can be used in-doors or out
MEWPs include cherry pickers, scissor lifts and vehicle-mounted booms
