  The following information is contained with SP Energy Networks document OPSAF-12-025 Issue No.6: Insulated Gloves for Electrical Purposes Other Than HV Rubber Glove Working.  

IEC 60903

IEC60903 produced by the International Electrotechnical Commission is an internationally recognised electrical safety standard: Live Working – Electrical Insulating Gloves.

IEC 60903:2014 is applicable to electrical insulating gloves and mitts that provide protection of the worker against electric shock.

This standard also covers electrical insulating gloves with additional integrated mechanical protection referred to in this document as “composite gloves“. The third edition cancels and replaces the second edition of IEC 60903, published in 2002 and constitutes a technical revision which includes the following major changes:

• clarification of the requirements and tests for long gloves
• introduction of a new special property for gloves resistant to leakage current
• removal of the requirement for an area to mark the date of inspection
• the d.c. electric tests are no longer included in the normative part of the document but a proof test is suggested at the production level in a new informative Annex E
• preparation of the elements of evaluation of defects, and general application of IEC 61318:2007
• introduction of a new normative Annex H on classification of defects
• introduction of a new informative Annex I on the rationale for the classification of defects

INSULATED GLOVES FOR ELECTRICAL PURPOSEs

SCOPE

This section of the Energy Networks Live Working Manual (LWM) details the rubber gloves to be used by all persons who are required to work or test on, or in close proximity to, Live LV Conductors and for certain switching and testing activities on the Live HV System (up to 33kV). For Company employees it also describes the process for issue and replacement.

This document deals with gloves which comply with IEC 60903 (2014) Class 1.

The specification for the use and testing of rubber insulated gloves in connection with HV Rubber Glove Working is contained in OPSAF-13-001 (LWM 8.4) HV Rubber Glove Working techniques.

DEFINITIONS

Terms printed in bold type are as defined in the Scottish Power Safety Rules (Electrical and Mechanical) 4th Edition.

POLICY

Class 1 7.5kV insulated rubber gloves to the relevant IEC 60903 (2014) standard shall be issued to SP Energy Networks employees and its appointed contractors who are required to work or test on, or in close proximity to Live LV conductors. They are not meant to be the sole means of protecting those who work or test on Live LV conductors.

These IEC 60903 insulating gloves shall also be issued to personnel who are required to operate air-break switch disconnector handles, overhead Apparatus in substation outdoor compounds, link / fuse operating rods or to use moving-coil Approved voltage indicators on the HV System.

Class 1 insulated gloves shall not be used for HV Rubber Glove Working on Live HV conductors.

Note: although Class 0 rubber gloves are rated for 1000V and would be appropriate for Live LV systems, experience has found them to be prone to damage when the gloves are not used with gauntlets. Class 1 gloves are thicker and more suitable to be worn without gauntlets if required.

Class 0 gloves shall not be used by SP Energy Networks employees or its appointed contractors on the SP Energy Networks System.

The SP Energy Networks specification TSE-03-044 for rubber gloves according to IEC 60903 require a high level of electrical arc flash protection. It is strongly recommended that insulating gloves provided by contractors provide an equivalent level of protection.

It is recommended that a leather protective outer gauntlet be used while operating on the HV System to prevent premature damage. Gauntlets shall be available for Persons with a preference to use them while working or testing on, or in close proximity to Live LV conductors.

Leather gauntlets also provide electrical arc protection which augments that provided by the rubber glove.

A protective wallet, to the relevant SP Energy Networks standard for the storage of rubber gloves shall be issued to all Persons issued with rubber gloves.

SP ENERGY NETWORKS GLOVE REPLACEMENT POLICY

This section describes the SP Energy Networks policy for replacement of damaged or time-expired insulating gloves to IEC 60903.

Contractors shall implement their own policy which may complement or differ from the Energy Networks policy.

The rubber insulating gloves shall be replaced before re-testing is required.

Class 1 7.5kV insulated rubber gloves shall be replaced twice per year, i.e. at 6 monthly intervals.

When the insulated gloves are first removed from the sealed bag in which they are delivered, the date of opening shall be written on each glove along the edge of the cuff using a ball-point pen or similar.

All IEC 60903 rubber gloves shall be replaced in pairs.

The leather gauntlets and protective wallet need not be replaced at the time of replacement of rubber gloves, but only as required.

At the time of replacement, all gloves shall be destroyed by having the fingers cut off. Gloves which exceed 12 months from the manufacturer’s test date shall be destroyed in the same manner.

Individual pairs of insulating gloves may be issued at other times as required.

Insulated gloves issued must have the manufacturers test date stamped on each individual glove. Insulated gloves shall only be in use within 12 months of the test date. Gloves shall not be in use for more than a 6 month period.

Insulated gloves remaining in the store, which have not been issued and have been stored appropriately, can be issued for the remaining duration of the 12 month period from the manufacturers test date as long as it does not exceed 6 months of use.

ORDERING

The quantities of IEC 60903 gloves required shall be determined far enough in advance of the period of issue to permit an order to be placed and delivery taken immediately prior to the period of issue.

If supply chain difficulties prevent delivery of adequate supplies of replacement gloves, the Operational Assurance Manager (or nominee) may approve a temporary extension of use.

STORAGE

IEC 60903 gloves shall be kept in store unfolded in the containers in which they are delivered. They shall be kept in dry conditions, away from strong light.

SAFETY REQUIREMENTS IN USE

When issued, but not in use, gloves shall be kept in the protective wallet, which shall be used only for storing the gloves. The wallet shall be kept away from moisture, strong light, and the risk of mechanical or chemical interference.

On each occasion before use, insulated gloves shall be examined by the user to ensure that they are safe for use. The examination shall include the following:

1. Check that the manufacturer’s test date on the gloves is not more than 12 months old
2. Check that gloves have not been in use for more than 6 months
3. Check that gloves are clean and dry, both outside and in
4. Check that the rubber does not show blisters or abrasions
5. Stretch the gloves by hand and check for tears, cuts and punctures
6. Complete an air test to confirm no punctures
7. Replace immediately, if either of a pair of gloves shows signs of not being safe. Both gloves shall be replaced

If, as a result of the examination, either or both of the gloves is found to be unsafe, then the pair shall not be used.

PRECAUTIONS IN USE

Insulated gloves shall not be allowed to remain soiled or unnecessarily exposed to heat or light or allowed to come into prolonged contact with oil, grease, turpentine, motor spirit or strong acid.

Gloves shall be wiped clean on completion of work to remove any surface contamination.

When insulated gloves become heavily soiled, they should be thoroughly washed with soap and water then dried. If insulating compound such as tar or paint still adhere to insulating gloves, then those parts affected should be cleaned with approved cable cleaners or degreasant and then immediately washed and treated as described above.

Petrol, paraffin, or white spirit shall not be used to remove such compounds. Rinse the gloves with clean water after washing.

Any insulated glove, which becomes wet in use or through washing shall be thoroughly dried. Where heated air is blown into the glove, it shall not cause the temperature of the glove to exceed 55ºC.

Electrical Safety Trainers – Protect Wearers Against Electrical Risks Up To 18kV

• uploaded by - Chris Dodds Thorne & Derrick Sales & Marketing Manager

Electrical Safety Trainers

Rock Fall has developed what it said is the first Electrical Safety Trainer available in Europe.

A multi-award winning second generation family owned business, Rock Fall has positioned itself at the forefront of the electrical safety footwear industry as a leading manufacturer of linesmans boots and dielectric insulating boots to meet the ever-changing demands of the power transmission and distribution industry.

Recognising the strong growth and focus on clean energy and sustainability around the world Rock Fall have developed the first Electrical Safety Trainers available in Europe.

Certified against European and International Electrical Hazard standards the safety trainers are designed to protect wearers against electrical risks up to 18kV in accordance with the ASTM F2412-11 test method.

The range is in stock in the UK and available exclusively from the largest PPE resellers in the UK, including Thorne & Derrick.

The range, which has already been recognised by the industry for Innovation at the recent Professional Clothing Awards is driving quick and significant growth in Australia and New Zealand, with major electrical contractors specifying the products for their electrical operations.

The electrical hazard trainers comply with European and American Standards:

• EN ISO 20345:2011 SB P E FO WRU SRC
• ASTM F 2413-11 1/75 C/75 EH PR

Electrical Hazard Trainer

Speaking about the development, Richard Noon said:

“Electrical risks are increasing as the prominence of hybrid and fully electric vehicles continues to grow. In manufacture, service and at the end of life these vehicles must be handled safely using correctly specified electrical safety equipment.

Electric Vehicles aren’t the only driver for this, as we increase the pressure on our electricity networks, there will be even greater demand for preventative maintenance and work on live lines.

Increased pressure can cause accidents and to have an additional item of PPE to be the last line of defence, in our opinion is critical.

We have seen from the great improvements in Safety Management during the Crossrail project.

With HS2 electrification high on the agenda, from the view of a Electrical Safety Equipment manufacturer it’s important that our industry makes the most of these major infrastructure projects.”

VIDEO How To Verify Total Absence of Voltage By The Push Of a Button

• Guest Article by Glen Bate (Panduit Account Manager)

VeriSafe voltage tester

When servicing LV MV HV electrical equipment, workers must comply with safety regulations that require a voltage verification test to validate the absence of voltage.

This process requires strict adherence to prevent accidents and bodily injury, but includes many stages that can be complex and time-consuming when using hand-held portable test instruments.

This paper examines the costs and limitations involved with using a manual absence of voltage tester. It also describes a new technology for the factory floor that automates the process, reducing time, complexity, and costs.

VeriSafe^TM by Panduit is the first-of-its-kind voltage tester that determines the absence of voltage with just a push of a button. This revolutionary 2018 NFPA 70E compliant product automates the required six-step testing process in about ten seconds, enabling your plant to operate faster, safer, and more efficiently.

Simplify electrical safety with the superior technology of VeriSafe.

Historical Costs of Checking for Absence of Voltage

Numerous studies exist pertaining to injuries resulting from electric shock and arc flash events. These studies recognise that establishing the economic payoffs of prevention is a critical factor in promoting workplace safety. Besides personal injury, the costs of property and equipment damage need to be considered.

Although estimates vary, studies have shown that the average direct cost of an electrical injury ranges from about US $50,000 to US $80,000′, while the indirect cost can exceed the direct cost by a factor of nearly four². Direct costs include lost wages or workers’ compensation payments, medical expenditures, and legal expenses.

Indirect costs include:

• wages paid during work stoppage
• administrative costs related to injury
• property damage and repair
• training and compensation for replacement workers
• lost productivity with less experienced workers
• fines related to workplace safety violations
• potential increase in absenteeism
• decrease in morale

Electrical injuries have one of the highest average workers’ compensation costs, second only to motor vehicle accidents³.

Injuries from contact with exposed wiring, transformers, or other electrical components frequently occur in the workplace and involve construction, installation, maintenance, and repair workers. These injuries are often costly and serious, as demonstrated by the number of days away from work; 51% of workers missed over one week of work due to these injuries, with 40% missing two weeks or more⁴.⁵.

Limitations of Using a Handheld Voltage Tester

Verifying the absence of voltage is part of the process to establish an electrically safe work condition. Step 5 of NFPA 70E-2015 Article 120.5⁶ describes this process:

Use an adequately rated test instrument to test each phase conductor or circuit part to verify it is de-energized. Test each phase conductor or circuit part both phase-to-phase and phase-to-ground. Before and after each test, determine that the test instrument is operating satisfactorily through verification on a known voltage source.

This process usually involves a portable, hand-held voltage test instrument. To be effective, it is critical to perform each step of the process in sequence, and it requires taking the necessary precautions, such as the proper use of personal protective equipment (PPE) (Figure 1).

Competent & Authorised Persons

Note Panduit recommend that VeriSafe should be used by competent and authorised people. As VeriSafe is a new and innovative solution to make the Absence of Voltage Testing, we recommend that the people who will use this device, have to be trained in order to understand how it works and how to use it properly.

Please be aware that with this product there is no risk of having hazardous voltage on the indicator module and on the door, as they are isolated from the main power by the isolation module which is located inside the panel. This means that there is less than 5 volts (just enough to power the LEDs on the indicator) present at the device located on the door and used to launch the test procedure.

Complexity

Adhering to this process prevents electrical injuries, but the process is complex and time consuming. Portable instruments are susceptible to mechanical and electrical failure and misuse by the person using the device. In addition, because the process of using a hand-held tester is dependent on human input, interaction, and interpretation, it is vulnerable to mistakes and errors.

Training Costs

Training on the selection, maintenance, and use of test instruments is crucial as are systems for inspecting and maintaining voltage test instruments. However, training and maintaining the test equipment incur the additional expenses of time and cost.

The Risks of Voltage Testing

Portable Handheld Voltage Detector in Action

Electrical Safety

Traditional Method – Determining absence of voltage with handhled testers presents a risk of exposure to electrical hazards

A disadvantage of implementing a voltage verification test with a hand-held tester is that the person performing it may be exposed to electrical hazards while verifying that the tester is working prior to and after the test, and during the test if the equipment was not de-energized.

With such a significant emphasis on performing work only on de-energized equipment, it is ironic that best practice relies on PPE and exposure to hazards before de-energized work begins. The need for PPE is a significant contributor to the overall time to carry out this process because the worker must first determine the required PPE, then obtain, inspect, dress, and properly store it after use. Additionally, PPE can be misused or not used at all, especially when there are time constraints.

When processes are overly complex or time-consuming, workers tend to become complacent and develop shortcuts as practices become routine. A normalization of deviance—small, gradual deviations from an established practice—may occur over time. With the lack of negative consequences, the lower standard eventually becomes the norm”.

Even when hazards are part of the everyday routine, deviations from a safety procedure can slowly become accepted practice. These deviations are particularly evident when there are time pressures, which is often the case when electrical maintenance causes unplanned or excessive downtime. If either training or enforcement of administrative procedures is lacking, the effectiveness of the procedures will diminish.

A More Efficient Way to Test for Voltage­ VeriSafe^TM Absence of Voltage Tester (AVT)

VeriSafe AVT – Prevents direct exposure to electrical hazards and determines voltage status before equipment is accessed

The VeriSafe^TM AVT automates the voltage verification process and is the first AVT tailored for electrical enclosures (Figure 2). By automating this process, the VeriSafe^TM AVT features the following:

• Tests without exposure to harmful voltages/currents
• Self-contained; no additional meters or tools are needed
• Built-in pre-/post-verification test
• Tests phase-to-phase and phase-to-ground
• Automated test sequence
• Active indication for absence of voltage
• Supports compliance with NFPA 70E-2018 Article 120.5
• Rated safety integrity level (SIL) 3 per IEC 61508

The VeriSafe^TM AVT is applicable for several applications:

• Equipment with a single source of incoming power
• High risk associated with access
• Equipment with high incident energy
• Remote or difficult to access locations — Outdoor, mezzanine, catwalk
• Sites with temporary or intermittent power
• Equipment with stored electrical energy — VFDs, capacitors, etc.
• Equipment frequently serviced by third-party technicians or contractors

Figure 2 VeriSafe AVT

NFPA 70E

One of the major changes to the 2018 edition of NFPA 70E involves the new requirements that allow an installed AVT to be used instead of a hand-held voltage tester. When the VeriSafe^– AVT is used in conjunction with a Lockout/Tagout Program, it meets the requirements for the process described in NFPA 70E-2018 Article 120.5:

Exception No. 1: An adequately rated permanently mounted test device shall be permitted to be used to verify the absence of voltage of the conductors or circuit parts at the work location, provided it meets the following requirements:

1. It is permanently mounted and installed in accordance with the manufacturer’s instructions and tests the conductors and circuit parts at the point of work
2. It is listed and labeled to verify the absence of voltage
3. It tests each phase conductor or circuit part both phase-to-phase and phase-to-ground
4. The test device is verified as operating satisfactorily on any known voltage source before and after verifying the absence of voltage

Figure 3 Comparison of the VeriSafe AVT and Portable Device Testing Methods

VeriSafe AVT – The Safe, Efficient, Accurate Way to Verify

Integrating the VeriSafe™ AVT is a vital improvement to absence of voltage testing. A solid testing method helps create a reliable, safe, cost-effective system that workers can use as needed. The VeriSafe^™ AVT verifies the absence of voltage before equipment is accessed, making it easier for qualified electrical workers to determine an electrically safe environment in a fraction of the time required by hand-held portable test instruments.
