1. LEIA SAFETY CHARTER Safety Training Presentation No 3
Electrically isolate and lock off when power is not required and when working close to unguarded machinery
(Note to Presenter: Check that your Management has signed the Safety Charter. This is referred to in the presentation. These Notes explain the slides and provide additional information. Whenever possible, engage your audience in discussion so that they can explore the risks experienced in the field and how they must be controlled. You are recommended to have read and have to hand a copy of the LEIA Information Sheet Nº 8 on Electrical Live Working)
(Note that the text and pictures on several slides will fade in and out on your click to emphasise a point. You are recommended to practice with this presentation before presenting to an audience)
The LEIA Safety Charter was devised as a means of combating the rising number of fatal accidents in the Lift and Escalator industry.
Within the last 20 years there have been 12 fatal accidents to engineers and field workers. The Charter was issued to LEIA Members on 22 March 2011 to make companies aware of their responsibilities, this presentation is prepared so that engineers and operatives can be aware as well.
Engineers and operatives will be asked to sign the revised LEIA Site Handbook with a commitment to the three elements of the LEIA Safety Charter.
V5-10 October 2012

2. LEIA Safety Charter Accidents
Over the last 20 years there have been 12 fatal accidents within the UK lift and escalator industry
How have the fatal accidents occurred?
Falling from height
Crushing/ struck by moving equipment
Electricity
The three most significant hazards are:
Falling from height and falling objects
Struck by moving parts
Electricity
Get your audience to suggest what they think are the most hazardous things (in terms of fatal accidents – manual handling is the cause of most injuries in L&E industry, but these are generally not fatal).
A click will reveal each hazard in turn.

3. LEIA Safety Charter
A copy of the Charter was sent to the management of every LEIA member for signing. The management were asked to sign to demonstrate their commitment to safe working. Now it is the turn of the engineers.
Describe the Charter:
‘Committed to working in accordance with BS 7255 or 7801’
‘our employees will...’
‘Protect themselves and others from falls and falling objects’
‘Use and verify Stop and other devices... Total control of the equipment’
‘Electrically isolate and lock off’
Stress ‘We (ie management) will actively ensure that our commitments are monitored and enforced…’
Reiterate that management have already signed this Charter (Check that this is the case before you present this)

4. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery The Risk…
Approximately 20 fatalities per year in UK (all industries).
Electrical injuries caused by a range of voltages – dependant upon circumstances
230V can, and does kill…
Equipment flashovers, burns, loss of muscle control, consequential falls from height etc.
Add background detail from your company if you have any, otherwise run through the bullet points

5. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery The Risk…
Shock is the effect of current flowing through the body
Current does the damage
Causes muscles to contract, tissue damage and internal burning
Can cause cardiac arrest and respiratory failure
The higher the current: the shorter the duration for injury
Electrically isolate and lock off when power is not required and when working close to unguarded machinery
The Risk…
Add background detail from your company if you have any, otherwise run through the bullet points

6. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery The Risk…
Threshold of sensation: 0.5mA
Threshold of pain: 5mA
‘Let-go’ current ( ): 10mA
Ventricular fibrillation (heart spasms): 50mA
60W light takes 250mA
Source: DD IEC/TS :2005
sufficient to cause spasms, but still allowing ‘let go’
Explain the ‘let-go’ current: The maximum current that can cause the flexors of the arm to contract but that allows a person to release his hand from the current's source is termed the let-go current.
Explain ventricular fibrillation is irregular spasms of the heart muscles. Above 200mA, muscle contractions are so strong that the heart muscles cannot move at all.
Click to give an example of the current used by a 60W lamp

7. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery Safe Working with Electricity
Always take precautions when working on or near live electrical equipment.
Lock and tag out the supply [or, if not possible, remove the fuses and take them with you] when power is not required to perform the task.
Ensure that you verify that the disconnection has been made
NOTE: Electrically isolate and lock off applies equally to escalators, service lifts, lifting platforms and other equipment in addition to conventional lifts
Electricity hazards occur on Maintenance Work and during testing and commissioning and applies equally to all equipment including Escalators, Platform Lifts, Service Lifts and Stairlifts as well as conventional lifts. Click 3 times to reveal a bullet point taken from the LEIA Site Safety Handbook:
Always take precautions when working near electrical equipment.

Explain that the procedure for proving dead should be by use of a proprietary test lamp… this is HSE preferred, but some companies will assess the risk differently.

Consider other sources which could remain live – see later slide
Reinforce the message that other sources of electricity may still be present even though the main switch is isolated.

16. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery Safe Working with Electricity
Regulation 14 Work on or near live conductors
No person shall be engaged in any work activity on or so near any live conductor (other than one suitably covered with insulating material so as to prevent danger) that danger may arise unless -
(a) it is unreasonable in all the circumstances for it to be dead; and
(b) it is reasonable in all the circumstances for him to be at work on or near it while it is live; and
(c) suitable precautions (including where necessary the provision of suitable protective equipment) are taken to prevent injury.
Electricity hazards occur on Maintenance Work, fault finding and during testing and commissioning.
Emphasise that this extract from the Electricity at Work Regulations 1989 is the law and must be complied with; not just a ‘nice to do’
Remind that they are live working as soon as they open a live cabinet

17. LEIA Safety Charter
Electrically isolate and lock off when power is not required and when working close to unguarded machinery Safe Working with Electricity
When the equipment must remain energized, effective insulation and safe electrical working practices must be used e.g. insulating rubber gloves, eye protection, insulating rubber mats on floor, insulating plastic shroud, all before accessing live parts, electrically insulated tools to minimise the risk of injury.
Avoid the chance of earthing yourself by removing or
covering jewellery.

When the equipment must remain energized, effective insulation and safe electrical working practices must be used e.g. insulating rubber gloves, eye protection, insulating rubber mats on floor, insulating plastic shroud, electrically insulated tools so that there is no risk of injury.
Precaution if equipment is accidentally live - use insulated tools (BS EN 60900) and maintain them in good condition – HSE recommend no more than 3mm exposed tip
Fit an insulating shroud to protect against accidental contact with live terminals and wear eye protection to protect against flash
Verification of rubber gloves
Use an insulating rubber mat (BS 921)
Wear insulating rubber gloves (BS EN 60903) until isolation is proven
