Statistics Fatal Electrical Accidents In Ireland 2001– 2011 33 Fatalities In 2005 there were 5 people electrocuted – 2 of these fatalities were with Low Voltage (LV) = 50 – 1000 volts. In 2006 there were NO Electrical Fatalities in Ireland First time since 1936
What is Electricity? SO WHAT IS IT MADE OF!!! Electricity is made up of a range of components e. g. Voltage – Current – Resistance – Power.
What is Electricity? Aluminium Atom 13 Electrons 29 Electrons Nucleus Electricity is the moving of Electrons in a wire or conductor and the consequence of this movement.
Voltage Levels ~ Extra Low Voltage = < 50 Volts ~ Low Voltage = 50 – 1000 Volts ~ Medium Voltage = 1 k. V – 38 k. V ~ High Voltage = 38 k. V- 400 k. V
Current n Current = Movement of Electrons Current measured in Ampere’s or amps Symbol = I or A
Types of Current DIRECT CURRENT (DC) ALTERNATING CURRENT (AC)
Frequency n Frequency of a system = Number of cycles per second n In Ireland this = 50; n It is measured in Hertz (Hz) n 50 hz
Stroboscopic Effect n May cause rotating objects to appear stationary or at least moving slowly n Fluorescent lighting – Problems n Solution – Filament lighting adjacent to machine n Solution – Supply each row of lights from separate Phases
Effects Of Electric Current Heating Effect – caused by friction Examples – Kettle, Cooker, Space Heater, Immersion & Light bulb
Effects Of Electric Current Magnetic Effect Voltage Examples – Motors, Transformers, Relays, Contactors & RCD’s
Resistance n Resistance = Opposition to current flow Resistance due to type of material & CSA Higher Resistance due to smaller CSA Measured in Ohms - Symbol = R or Ω
Power Is the rate at which Current flows at a given Resistance and Voltage Power = Voltage x Current Measured in Volt-amps / Watts e. g. 10 VA 15 k. VA /k. W
IP Rating n n IP rating of equipment refers to the electrical equipments ability to withstand the ingress of either liquids or solid bodies IP 56 ; In this example the Ingress protection offered by this equipment is given by the two numbers. The first number refers to the protection against the ingress of solid bodies. The second number refers to the protection against the ingress of liquid.
IP Rating Example of IP rating n IP 45 = Protection against normal dust and hosing and is suitable for Dairies. n IPX 4 = only protected against hosing is given
Electrical hazards associated with electrical systems and equipment include: • Electric shock • Burns sustained at the point of accidental electrical contact, or due to arcing from high voltage conductors • Fires caused by overheating or ignition of explosive atmospheres • Secondary injuries as a result of muscle spasms during shock or, for example, falling from a ladder after a mild shock.

Electrical Safety It is an employer’s duty to provide staff with Safe Systems of Work It is absolutely essential that they have safe work methods and procedures in place to ensure the safety of all who work on electrical equipment or installations:
Electrical Safety When it comes to Electrical Work there are only two scenario’s: ~ Working on Equipment ‘Dead’ ~ Working on Equipment ‘Live’ There is no in between Therefore a Safe Operating Procedure is required for both.
Working on Equipment ‘Dead’ It is always preferable to work on ‘dead’ equipment or installations (SI 299). Any Procedure for making Electrical Equipment ‘Dead’ e. g. Lockout/Tagout Procedure should be based on the 5 golden rules: 1 Disconnect from the power supply 2 Prevent re-connection (lock-off) 3 Check for absence of voltage 4 Earth and short circuit (if appropriate) 5 Protect from adjacent live parts
Lockout and Tagout Procedure based on 5 Golden Rules PURPOSE ~ To comply with Health and Safety legislation ~ To protect employees from any unintended release of potentially hazardous energy while setting up, adjusting, repairing, servicing, maintaining or installing equipment or machinery.
Lockout and Tagout When to use: Lockout and Tagout must be used where the unexpected energising, start up or release of stored energy could occur and cause injury. Who should use: All personnel authorised to implement a Lockout and Tagout system. Personnel trained in the identification of energy sources, location and operation of isolating equipment and utilisation of Lockout and Tagout devices.
Lockout and Tagout What is Lockout: The placement of a Lockout Device on an energy isolation device to ensure that the isolation device and the system it controls cannot be accidentally or inadvertently operated. What is Tagout: The placement of a Tagout Device on an energy isolation device to indicate that the isolation device and the system being controlled should not be operated until the Tagout Device is removed.
Lockout and Tagout Lockout devices must: ~ Be approved type and robust enough for the environment in which they will be used. ~ Only be removed by the person who applied them. ~ Only have one available key in the possession of the approved person
Lockout and Tagout devices must: ~ Be securely attached with a self locking device ~ Be able to withstand the environmental conditions ~ Only be removed by the person who applied them. ~ Be prominently displayed and identify the person who attached the Tagout device
Electrical Contractor Management ~ ~ ~ ~ ~ Valid Public Liability Insurance Contractor Safety Statement Contractor Job Method Statement Risk Assessment Site Induction Permit to Work – Lockout Permit Competent workers (with Safe Pass) Suitable Safety Equipment & PPE Suitable (certified & tested) Instruments
Working on Equipment ‘Live’ Electrical equipment or installations are deemed to be ‘Live’ if they are not ‘Dead’ i. e. switched off, locked off and verified that it is off. Live Working should be the exception and only carried out when it is unreasonable for the electricity supply to be switched off and suitable precautions are taken to minimise the risks.
Live Working Precautions ~ ~ ~ The use of people who are properly trained and competent to work safely on live equipment. The provision of adequate information to the person carrying out the work about the live parts involved and the likely risks. The use of suitable tools including insulated tools, equipment and protective clothing. The use of suitable insulated barriers or screens. The use of suitable instruments and test probes. Accompaniment by another person if their presence could contribute significantly to ensuring that danger is prevented.
Personal Protective Equipment (PPE) Arc Flash Protection Overalls These overalls are designed to protect the body from burn injuries resulting from electrical short circuit. EN 61482 Electrical Insulated Gloves These gauntlet type latex gloves should comply with the international standard EN 60903. They should be stamped with the live working symbol along with Class 0 to indicate they will insulate up to 1000 volts. Before use each glove should be visually examined and inflated to check for damage and punctures. Any glove that fails the tests must be cut up and scrapped immediately. Live Working Symbol = Electrical Insulated Mat The insulated mat provides effective means of improving protection against second point of contact. It should be stamped with the live working symbol and the level of voltage to which it will insulate. Electrical Insulated Boots The insulated boots should comply with the international standard EN 50321. They should be indelibly stamped on the inside of each boot with the live working symbol, the level of voltage to which they will insulate and the month and year of manufacture. The boots must be checked for cuts, punctures or worn soles before use.
Personal Protective Equipment (PPE) Face and Eye Protection A full face visor complying with the international standard EN 166 must be worn where there is a risk of face or eye damage from electrical short circuits. Insulated Shrouding is designed for temporary protection against accidental contact during work. It should be stamped with the live working symbol and indicate the level of voltage to which it will insulate.
Personal Protective Equipment (PPE) Test Instruments All test instruments used on Live electrical equipment Must be fully insulated to a minimum voltage level of 1000 volts. They should comply with the international standard EN 61243 Test Instrument Leads and Probes Test equipment connecting leads and probes should be sufficiently protected to prevent accidental contact when being applied to and removed from live parts e. g. maximum of 3 mm exposed metal tip of probe.

Testing of Tools/Equipment
Portable Appliance Testing USE OF WORK EQUIPMENT It is the duty of every employer to ensure that in the case of work equipment which is exposed to conditions causing deterioration liable to result in a danger to safety or health, that periodic inspections and, where appropriate, testing is carried out. The results of inspections should be kept for 5 years from date of inspection.

ELECTRICAL SAFETY-High Voltage ~ Access to HV Apparatus must be restricted to authorised personnel only ~ Doors & gates to rooms, cubicles and compounds: q q Must be kept locked to prevent entry by unauthorised personnel, and, Key must be controlled.
Working beneath a Live Line ~ Where work is to be carried out close to a live line, ESB Networks insist on the line being switched out for the duration of such work. ~ In some situations work will be allowed but only after detailed consultation and with the understanding that strict safety precautions will be employed. ~ In addition to all previously mentioned precautions a barrier of timber or an earthed steel net will be erected under the supervision of ESB at a height also determined by ESB.
Working in Proximity to Overhead Lines ~ Sites where there will be no work or passage of plant under a live line require barriers to prevent close approach. ~ Sites where plant will pass under a live line require defined passageways under the line to be made. ~ Sites where work will be done beneath a live line require further precautions in addition to the provision of barriers and passageways.
Passage beneath a Live Line ~ Contractor should erect wooden or nonconducting material goal posts at the entrance to the passage on each side of the line. ~ The goal posts should be in line with the protection barrier. ~ The passageway should be as narrow as possible, not exceed 10 metres and should be fenced or have steel drums on either side.
Overhead lines generally bare conductors Working in proximity to Overhead Lines
Excavation Work should not commence on any excavation until all precautions to avoid contact with underground cables have been taken The basic elements of a safe system of work involves: a. Correct use of Plans (to aid location of power cables) b. Use of Cable Locating Devices c. Use of Safe Digging Practice
Farms n Farm buildings have special safety requirements for electrical installations and equipment. n Farm working conditions and hazards place much heavier demands on electrical equipment. Special wiring rules for farm buildings must be followed to avoid the risk of accidents. n Domestic equipment is not suitable for use in farm buildings. n A comprehensive booklet 'Farm Well Farm Safely' is available that gives detailed advice on using electricity safely in and around the farm.
New Installations If you are having a new house wired or having existing wiring renewed or extended you should get an ETCI Completion Certificate from your electrical contractor. This certificate is your contractor's statement that the installation complies with the National Wiring Rules. This certificate will also be required before a new supply can be connected.
