Dielectric gloves protect hands from electric shock. From the material of this article you will learn what features seamless varieties are possessed, how to choose them correctly and use.
Dielectric seamless gloves are part of electrician equipment. They are used when working with electrical appliances and electrical cables. Security tools are needed when necessary:
- Disable / connect a current collector with a voltage of more than 800 V;
- replace high voltage fuse;
- replace the lighting device;
- disconnect the transformer terminals;
- Work with a reversing distributor element.
Dielectric seamless gloves make the safe operation of electricians serving electrical installation, power lines, electrical equipment.
In this case, depending on the variety, they can become an additional protection means if the voltage exceeds 1000 V.
If they are selected in size, when they are used, the full user’s performance is saved.
SIZ data are subject to developed safety requirements. Gloves made by seamless casting method are convenient. They enjoy professionals, performing the work of a different level of complexity. The range of products is small, however, the choice requires special care. The slightest error may result in an injury obtained due to lesion.
Dielectric gloves tested twice a year. Tests are carried out in the laboratory, creating special conditions. It uses special containers with a liquid, immersing gloves in them so that water is not only outside, but also inside. Moreover, the straightened upper edge of each pair should not be immersed in water at least 5 mm. For one minute, voltage is 6 kV.
At the same time, the leakage current should not exceed 6 mA. After testing, the gloves are dried in a special chamber, then they put a stamp indicating the period of use until the next check. On average, the value of the tests of one pair can be 195 rubles, provided for 5 days. Optionally, you can check a couple for 1 day, paying 295 rubles.
You can classify dielectric seamless gloves by two features: material manufacturing and number of fingers. Produce personal protective equipment from rubber-based compound (sheet rubber or latex). Due to the use of natural raw materials, the product does not irritate the skin of the hands and do not cause allergies.
Latex and rubber dielectric gloves differ in the size of the krag. It is selected in such a way that it is convenient to work in gloves.
Models for work at a negative temperature differ greater width.
This is done so that jerseys can be put on the gloves (for example, knitted crags or warm mittens).
In the number of fingers, the product is traditional five-plated and bobby. Options of the second type are less convenient, five-panels do not limit the user. When choosing one or another option, you can not forget about the voltage level. Based on this, the products are divided into 2 groups: “EV” and “En”.
According to GOST 12.4.103-83 Marking “En” indicates that the product can be used as a means of current protection at a voltage of up to 1000 V. Mark “EV” indicates that gloves are suitable as an additional protective agent for setting more than 1 kV. At the same time, they are used with electrical insulating ticks and rods.
How to choose?
Choosing dielectric gloves, you need to consider several key criteria. For example, high-quality rubber products for working with a voltage to 1000 V and more than 1 kV have 2 layers of different shades. Marking with the number is on their outer side.
According to the provisions of the GOST, dielectric gloves are common, as well as intended for particularly thin or, on the contrary, hard work. SIZ is not at all universal: you need to buy those products that match the appointment. For example, products intended for coarse work must have a wall thickness up to 9 mm. Analogs for subtle work should not be thicker 4 mm.
You need to buy models in which kragi can easily wear on warm or knitting mittens.
The optimal length of the dielectric gloves should be at least 35 cm (measured from the tip of the index finger to the edge of the product).
It is important to buy products in size taking into account mittens or gloves worn under them. Too large PPE can complicate the user.
As for the type of product, it all depends on the destination. Sometimes bobby varieties can be applied to work. When performing subtle work, do not do without modifications of a five-pall type. Choosing your option, you need to pay attention to the quality of manufacture. The vapor pair should not be residual traces of production (for example, protruding rubber fibers, as well as other defects).
You can use only those gloves on which there is a stamp with the specified test protocol. At the same time, products should not be mechanical damage. Cannot use wet or dirty PP. Before starting work, you need to check the products for punctures or cracks. For this gloves are put on a flat surface and twisted aside the fingers.
Before each use you need to inspect gloves. If everything is in order, they can be used half a year from the moment of checking, after which they must be repeated testing. If the check reveals cracks or punctures, gloves should be replaced with new.
In order to protect gloves on them you can wear tarpaulin mittens. In the course of work it is necessary to ensure that the edges of gloves are not wrapped. From this violates user security. It is impossible to inflate the gloves of the mouth, from this they can become wet.
It is impossible to ignore and disinfection, for which a solution of soda or soap is used. Wear gloves need over top of clothes. When working near sharp edges, you need to wear leather mittens on dielectric gloves.
You can not ignore storage rules. Rubber collapses under the influence of heat, gasoline, mineral oils, ultraviolet rays and alkali solutions. Store products need away from heating devices and radiators, not forgetting about the optimal level of humidity. You can not store gloves under straight sunny rays.
