SECURA B.C. is one of the leading manufacturers of personal protective equipment for breathing and hand protection. We particularly want to emphasise the fact, that we are the only manufacturer in Poland and the Central and Eastern European which offers electrical insulating gloves for working on live systems that meet the requirements of PN-EN 60903:2006 (EN 60903:2003+AC2:2005) “Working on live systems. Gloves of insulating material”.
Electrical insulating gloves are classified as PPE of complex design, intended to protect against threats to life or threats of serious and irreversible body injury (Category 3). ELSEC gloves manufactured by SECURA B.C. hold EC type approval certificate in accordance with Directive 89/686/EEC and Regulation of the Minister of Economy of 21 December 2005 (Journal of Laws No. 259, item 2173). which authorises the manufacturer to mark products with CE mark. They are also approved for use in underground excavations with methane explosion hazard class “b” and “c”, and coal dust explosion hazard class “A” and “B”.
With a view to developing and providing high quality products manufactured by SECURA BC, in 2006, the company implemented a quality assurance system based on ISO 9001 “Quality Management Systems. Requirements”. As a result of annual audits performed by the notified body supervising the process of issuing and use of quality management system certificate, SECURA B.C. is issued new QMS certificates to confirm that the implemented system works correctly. ELSEC electrical insulating gloves are designed for hand protection against electric shock while working on live systems. Under the current regulations, these gloves may be used as protective equipment when working with voltage up to 1kV. When working with higher voltages, electrical insulating gloves may be used only as auxiliary protective equipment, which means that they must be used in conjunction with other technical security measures.
ELSEC gloves are manufactured in five voltage classes: 00, 0, 1, 2, 3 and five sizes: 8, 9, 10, 11 and 12 with different hand and wrist circumference. All ELSEC gloves meet the requirements of PN-EN 60903:2006 (EN 60903:2003+AC2:2005) in terms of voltage requirements, as well as in terms of increased resistance to acids (category A), oil (category H) and ozone (Z category) and extremely low temperatures (category C). ELSEC gloves are marked as category RC, where category R combines the three above-mentioned categories, R = A+H+Z.
ELSEC electrical insulating gloves are manufactured of high-quality rubber latex on automated line. Chemical raw materials used to prepare the latex mixture to produce the gloves are of high quality and purity and have been supplied to us by qualified and quality assuring manufacturers for many years. Each batch of raw material has a quality certificate guaranteeing that they meet the parameters and criteria requested by SECURA B.C. In addition, each batch of rubber latex imported from Malaysia and Thailand is subject to inspection and examination in factory laboratory to check if critical parameters are met which guarantee its characteristics and quality in the manufacturing process. Processing line to manufacture ELSEC electrical insulating gloves is fully automated, allowing production control and monitoring, and guaranteeing that all physical and physicochemical parameters affecting the production process and product quality are met. Widely developed inter-operative control regarding the checking of chemical raw materials, technological parameters, semi-finished and finished goods further ensures that high quality is maintained.
Each glove is electrically tested on a modern computer-controlled test bench as a part of product examination in accordance with the requirements of EN 60903. Alternating voltage is supplied to the glove and the voltage value depends on the class of glove to be tested. Computer system controls the conditions for electrical gloves testing, monitors the process and registers measurement data.
It has the following features:
– Sets the test voltage,
– Controls the duration of the test,
– Measures and records in the database the following parameters of each test glove containing information, among others, about the maximum and effective test voltage, effective leakage current for each of the gloves tested at the same time, and air and water temperature in the glove tank.
As a result of the test, an individual test report for each glove is generated, which includes information about electrical parameters of the glove immediately after its production. The report is stored in a database. Individual numbering of each glove during test was introduced in 2003. Each glove receives its own individual number and a certificate of acceptance test, making it possible to exert full control over the production process of each glove and restore these data, as well as allowing for monitoring and analysis of electrical tests. Implemented instructions and internal QMS procedures are developed in such a way as to ensure full traceability of raw materials and retracing the whole production process using the number given to the glove during electrical test. This allows you to trace the process in the case of production batch problems, and, as a result, to improve parameters and manufacture high quality gloves with full repeatability of technical parameters.
Individual numbering of ELSEC gloves allows you also to track any changes in their parameters during use. It is required to perform control electrical testing on regular basis, when the leakage current is measured at the specified test voltage. The method and conditions of storage may substantially affect the technical condition of electric insulating gloves. Manufacturer’s recommendations and standards must be strictly followed. Glove material, that is rubber latex, is subject to aging, reactions with chemical agents. The gloves can also be mechanically damaged, that is why it is so important to carry out the inspection tests.
ELSEC gloves are five-finger gloves, with are characterised by anatomical shape, flexible and smooth surface which enables effortless operation and use of tools. If the work on live systems is done for a long time and at various temperatures, the fitter may feel discomfort due to hand sweating or freezing. Therefore, it is recommended to wear additional thin or thick cotton gloves under the electrical insulating gloves. This solution is also advantageous for occupational hygiene and it reduces allergic reactions to latex the electrical insulating gloves are made of. SECURA B.C. provides sweat-absorbing inserts made of thin cotton together with electric insulation gloves. The inserts substantially improve the comfort of work, isolate the hand from latex the ELSEC glove is made of and they absorb sweat. As a result, the hands are dry, the work is more enjoyable and safer. At the same time, the storage, maintenance and cleaning of ELSEC gloves is easier. Cotton insert, in contrast to flocked cotton, is easier to keep clean and hygienic, you can always take out the insert, wash it, dry it and then put it on again.
Leather protective gloves are worn over electrical insulating gloves as an additional protection against mechanical damage. The shape of leather gloves offered by our company, ie. ELSEC 2 and ELSEC 20 gloves (two types of gloves corresponding to two thickness ranges of ELSEC gloves), is designed specifically for the shape of ELSEC electrical insulating gloves, and they are made of specially tanned, thin, flexible and yet very strong goatskin.
They do not prevent the fitter from performing his/her daily activities, and simultaneously they increase safety and comfort of work. Safety of people using electrical insulting gloves when working on live system depends to a large extent not only on the fact that the gloves meet general requirements in terms of physical and technical parameters controlled by means of product tests or acceptance tests, but, as mentioned above, also on their proper use, storage, direct control before putting on, and regular control of their electrical parameters. The gloves should be stored in suitable containers or packages. Storage and transport conditions must protect the gloves from being crushed, bent, exposed to direct sunlight and artificial light, ozone, oil, lubricants, turpentine, acid and heat. The perfect solution that meets all of these requirements is our carrying bag for safe storage and transport of gloves, made of polyester coated with polyvinyl chloride (impermeable to moisture). It has three pockets for three types of gloves, sweat-absorbing inserts, ELSEC gloves and leather gloves. The bag is fastened with a press stud. It can be easily attached to the tool belt. Threats related to the performance of specific tasks on live systems is usually associated with a risk of electric shock caused by touch current passing through the human body on a particular path. However, a threat is also present in the event of short circuit in the nearest distance from the installer performing electrical work. The threat is then associated with the effects of electric arc caused by the short circuit. High temperature and thermal impact do not have to cause the flow of current through the human body, but they can cause burns. Despite the fact that there are no developed criteria and requirements for electrical insulating gloves resistance to electric arc, SECURA B.C. carried out such tests on ELSEC gloves in High Current Laboratory of the Institute of Power Engineering in Warsaw in 2016 based on the procedures developed at the Warsaw University of Technology in accordance with the following standards:
1. PN-EN 61482-1-1:2009: Working on live systems – Protective clothing against thermal hazards caused by electric arc – Part 1-1: Test methods – Method 1 – Determination of electric arc parameters (ATPV and EBT50) for flame retardant fabrics.
2. PN-EN 61482-1-2:2010: Working on live systems – Protective clothing against thermal hazards caused by electric arc – Part 1-2: Test methods – Method 2 – Determination of protection class of materials and clothing protecting against electric arc using forced and directed electric arc (test chamber).
For all the recorded measurement results of thermal energy, the values inside the gloves were smaller than the reference energy value. This proves the effective reduction of heat energy by all the ELSEC gloves tested to a level lower than the one that causes second degree burns on human skin with a 50 percent probability. On the basis of visual inspection of the condition of ELSEC gloves, performed after they were subject to thermal influence of the electric arc, no signs of ignition or physical damage were found, such as ruptures, perforation, melting or deformation. ELSEC gloves are properly labelled with a pictogram signifying that they were tested for the impact of thermal arc.
SECURA B.C. is the only company that offers ELSEC, latex electrical insulating gloves, which not only meet the requirements of PN-EN 60903:2006 (EN 60903:2003+AC2:2005), but were also tested with positive results for the impact of thermal electric arc in all the classes manufactured.
