Electricity kills and injures individuals. Around 1,000 electrical accidents at work are reported to HSE annually and about 25 individuals die of their accidents.

Many deaths and accidents come up from:

  • Use of poorly maintained electrical tools
  • Work close to overhead energy strains
  • Contact with underground energy cables throughout excavation work
  • Mains electrical energy provides (230V)
  • Use of unsuitable electrical tools in explosive areas reminiscent of automobile paint spraying cubicles
    Fires began by poor electrical installations and defective electrical home equipment.
  • Electrical accidents could be brought on by a variety of voltages however the threat of damage is usually higher with larger voltages and depends upon particular person circumstances.


Alternating present (AC) and direct present (DC) electrical provides may cause accidents together with:

  • Electric shock
  • Electrical burns
  • Loss of muscle management
  • Thermal burns.

This process provides easy steerage on what’s required in {an electrical} scheme of upkeep and inspection, nevertheless, competent electrical recommendation ought to all the time be sought when making ready such a scheme.

What is that this?

This is a written process that outlines the essential duties of a accountable supervisor to make sure the location manages electrical energy safely.

It is beneficial {that a} competent, certified electrical engineer is employed to develop and implement procedures for low voltage work.

A PDF of the process is offered to obtain (see connected), please use it together with the connected Electricity Scheme Template and Toolbox Talk.

What is required on web site?

The particular person accountable for implementing this process should make sure that:

Requirements of the Site Services Plan;
Maintaining updated distribution drawings;
Maintaining a list {of electrical} tools;
Lock Off Procedure;
Electrical Isolation Procedure;
Requirements for examination, testing and upkeep of low & excessive voltage tools;
Live Working Procedure together with Condition Monitoring;
Appointment of Non-Electrician as Competent Person;
The Procedure for Changing PLC Programme;
The Guidance on Underground Cables;
The Permit to Work; and
Electrical requirements and most well-liked electrical contractors.
What coaching will staff require?


Employees would require coaching in primary electrical security and firm procedures, to make sure they:

Know the right way to use tools safely.
Know what they don’t seem to be permitted to do.
Understand what motion they need to soak up an emergency involving electrical energy.
Know who’s authorised to hold out electrical work.
Know to whom electrical issues must be reported.
The procedures talked about above should be ready and accredited by a reliable electrical engineer. However, steerage is given under on what must be included in the primary subjects.

What is in a Site Services Plan?

A web site survey must be carried out, and a drawing produced to point out all web site companies both overhead or underground. A key must be developed in order to differentiate between the varied companies. Items on the plan embody:

  • Underground Electrical Supply LV
  • On-site electrical distribution line and depth
  • Gas
  • Water
  • Telecoms
  • Security Systems

The plan ought to have reference to fastened factors and the place attainable present service depths.

What is in an Isolation and Lock Off Procedure?

Specific steerage is given in separate procedures referring to Isolation and Lock Off.

A scheme of inspection and upkeep must be based mostly across the following construction:

Details of the system for managing electrical security.
An organisational construction for the scheme of upkeep.
Appropriate authorisation of competent personnel.
An in depth description of the scheme.
Testing specs, procedures and strategies.
Technical notes for particular tools.
The tools to be included within the scheme is as follows:

Electric Motors and related Cable, Isolator and so forth.
Distribution Cables
Stop Buttons and Pull Wires
Independent Plant Mounted Starters:
L V (as much as 1000V Primary) Transformers
Main Power Factor Correction Capacitors
The Control Panels, Contactors and Switches
Portable Hand-held Tools
Portable Office Equipment
Semi-portable Appliances, i.e. Welding Sets
The Lighting Circuits
High Voltage Equipment (Above 1000 V) and Overhead Cables
Residual Current Devices (RCDs)
Local Isolators
Can stay working be undertaken?

Live working
The Regulations state that stay working could be carried out solely after contemplating the next factors:

1. No Live working could also be carried out by individuals except they’ve ample information and technical expertise, and:

It is unreasonable in all of the circumstances for it to be made lifeless;

Electric shock;
Arc burn and hearth; and
Ignition of flammable gases.
The procedures adopted following evaluation ought to, the place related, embody:

The provision of sufficient info for the particular person finishing up the work concerning the stay conductors;
The use of appropriate tools and protecting clothes;
The use of appropriate insulated obstacles or screens;
The use of appropriate devices and take a look at probes;
Effective management of the world the place there’s hazard from the stay conductors; and
The provision of extra suitably skilled personnel.
Live Testing

Appointed electricians are totally accustomed to the tools to be labored on.

Adequate info is supplied in regards to the nature of the work and {the electrical} system to be labored on.

Where attainable, {the electrical} tools is fitted with a further change that can permit the 110 volt management circuit to be energised with the 415 volt provide being remoted.

Where attainable, {the electrical} tools is fitted to IP2X ranking, which in impact prevents inadvertent contact with any stay tools. If tools will not be fitted to IP2X ranking, a threat evaluation is carried out and, if obligatory, extra precautions are taken.

Only applicable take a look at devices and take a look at probes are used.

If obligatory, the particular person finishing up the work is accompanied by an individual who’s skilled in the right way to isolate the tools.

(This particular person additionally controls the world the place the work is being carried out and, if obligatory, restricts the entry to the constructing to make sure there’s a managed working atmosphere for the electrician finishing up the duty.)

What subjects are often included in coaching for non-electricians?

The following objects must be thought of inside the coaching programme:

  • Changing of lamps
  • Changing fuses
  • Resetting overloads
  • Emergency switching
  • Isolation of plant
  • Slip ring motor upkeep
