PPE – personal protective equipment for electricians

When repairing, connecting, or maintaining electrical equipment and networks, even when the voltage is removed, there is a possibility of receiving an electric shock. There is a risk that someone will turn on the switch or press the starter button; you may trip and touch live conductive surfaces. Based on this, current electrical safety rules require the mandatory use of PPE that can prevent electrical injuries or reduce the severity of damage.

Purpose

Complete with collective protective equipment, PPE is designed to ensure safe working conditions for one specific performer. That is, they can only protect the electrician who uses them.

Personal protective equipment for electrician

In practice, two main types of PPE are used, which differ in their operating principle:

• Insulating protective equipment prevents electric shock from direct contact with live parts of electrical installations. This category also includes means that provide insulation from the ground. Variants of such PPE are made using materials of the dielectric group, whose resistivity exceeds 108 Ohm*m.
• Fencing is required to prevent contact with parts of electrical equipment that may be live. Such PPE includes safety belts, claws, and barriers installed at work sites.

Every electrician must know the rules of use and the list of personal protective equipment required depending on the conditions of work. In addition, he needs to be able to check all the means at his disposal and have information about the frequency of tests that are carried out by specialized organizations.

PPE standards for electricians

Frequency of inspection of fire extinguishers and maintenance schedules

According to the standards and GOST, the PPE of an electrician for the repair and maintenance of electrical equipment must be fully or partially made of materials that do not conduct electricity.

List of PPE for electricians according to industrial safety standards:

• protective glasses;
• special suit;
• respirators;
• mask;
• dialectical gloves or mittens;
• galoshes.

Any protective equipment must comply with the established requirements of TR TS019/2011. It specifies not only the requirements for PPE against electric shock, but also the completeness, as well as the quantity (and timing) of issuance per employee and the frequency of checking PPE.

Classification

Current regulations also provide for the classification of PPE according to purpose and permissible conditions of use. It is customary to subdivide into:

• Basic electrical protection necessary for carrying out work in the presence of voltage on live parts of equipment or networks. The main requirement for such products is that they must have insulating characteristics that will allow them to withstand the voltage present for a long time.

  
  Basic PPE

• Additional electrical protection, which by themselves cannot protect a person from prolonged contact with live parts of equipment or mechanisms. They are used only in conjunction with basic personal protective equipment and are able to prevent injury when exposed to step voltage or accidental contact with conductive elements (touch voltage).

  
  Additional PPE

Each of the listed types, in turn, is divided into categories according to the permissible voltage at which their use is possible. There are two groups:

• PPE that allows you to perform electrical installation work or repairs, equipment maintenance at a voltage not exceeding 1 kV.
• Personal protective equipment for working on high-voltage installations or networks at voltages over 1 kV.

The main differences between the products of these groups are the quality of the dielectrics used. Note that the main tools and devices intended for up to 1 kV can be used as additional ones if the indicator exceeds this limit.

Basic PPE

The most common types used for working with equipment or electrical networks at voltages up to 1 kV include:

• Operating rods necessary for performing operations related to the maintenance or control of electrical installations. With their help, switching operations with disconnectors and grounding connections are carried out. They are a handle made of a material with dielectric properties on which an actuator or gripper is installed.

  
  Operating rods

• Measuring rods have a similar design, but instead of grippers they are equipped with equipment for measuring resistance, voltage, temperature, current, and other characteristics. Universal rods that combine the capabilities of operational and measuring devices have also found application.

  
  High voltage measuring rod

• Insulating pliers are designed to replace fuse links, busbar fuses and to perform other maintenance operations on live electrical equipment. The difference with operating rods is that they are a pliers tool with two long, insulated handles that allow you to perform work at a distance from parts of the equipment.

  
  Insulating pliers

• Electrical measuring instruments designed to take readings directly from conductive elements or contacts of electrical equipment. Clamps for determining current strength, megohm meters for monitoring insulation resistance, voltage indicators (VT) and other devices for monitoring the parameters of electrical circuits.

  
  Electrical measuring instrument

• Dielectric gloves also belong to the main types of personal protective equipment for work at voltages not exceeding 1000 V. Like other insulating clothing, they are used exclusively in a dry state, even the minimal presence of moisture on the surface can cause electric shock to the performer (the table with the date of the last check is shown in black , inspection organization, etc.).

  
  Dielectric gloves

• Part of the PPE consists of insulated hand tools, which every electrician who performs maintenance, repairs, connecting electrical equipment and when working with electrical networks should have. This list includes screwdrivers, pliers and pliers, pliers and side cutters. Open-end or socket wrenches, knives or strippers, and other devices are also used. It is recommended to use hand tools with VDE marking that comply with European electrical safety requirements. It is distinguished by multi-layer coating of hazardous areas with insulating materials. Moreover, the main protection is the top layer of polyformaldehyde, which has high dielectric characteristics.

  
  Isolated hand tool

Please note that when working at high-voltage installations, these basic personal protective equipment cannot ensure complete safety of work. If the value exceeds 1000 V, it is necessary to use specialized personal protective equipment:

• Rods and clamps whose insulating characteristics provide long-lasting protection against high voltage.
• Special devices and structures that should ensure the safety of measurement work. These include tools for piercing insulation, high-voltage electrical clamps and UN.
• To work on installations and networks with a voltage class of more than 110 kV, non-contact measuring devices are used, for example, voltage indicators.

Please note that only electricians with the appropriate permit can be involved in carrying out work in such conditions.

Additional protections

This category of PPE is also divided according to the permissible voltage at the work site. The difference lies in the dielectric characteristics, so we will give only a general list, but you should check the conditions under which they are intended:

• Protective dielectric footwear (boots, galoshes), which allow you to avoid the passage of currents through the body that are shorted to the ground. Such products are recommended for use in premises and kiosks in cases where the floor is made of conductive materials.

  
  Dielectric safety shoes

• Dielectric mats and insulating stands have a similar purpose. Can be used both indoors and outdoors, but only in dry weather.

• Insulating caps or covers to prevent equipment from turning on and causing electrical power to enter the work area.

  
  Insulating hoods

• Specialized suits, safety glasses, helmets to avoid injury in the event of discharges and other emergency situations.
• Portable structures and devices for fencing and grounding of conductive parts of serviced equipment.

  
  Portable ground electrodes

It is recommended to use a combination of primary and several auxiliary PPE.

Types of PPE for electricians and their use

Testing of fire escapes and roof railings: inspection frequency

To ensure the safety of working with electric current, every electrician or technical engineer at the enterprise must receive personal protective equipment and receive instructions for their use.

A mandatory element of equipment at many factories is a dielectric helmet. It will protect your head from mechanical damage or electric shock. The helmet is equipped with special insulation that protects against high voltage.

Helmet

Special openings for ventilation are installed in the side parts, which, if necessary, can be covered with shields. The helmet is secured on the head with adjustment straps and a forehead band.

Protective glasses

Glasses are a mandatory element of PPE for an electrician. They are made entirely of plastic, since metal parts are not allowed by regulations. There are clamps installed on the earpieces to prevent the glasses from falling. This is especially true if the electrician works at high altitudes.

Note! The lenses are made of high-strength transparent plexiglass. The glasses fit tightly to the head, and therefore the eyes will be completely protected from various small objects.

Work suit

Electrician PPE is made of dense material. Before release into production, specialists conduct tests to ensure that the work suit can protect a person from an electric arc.

Electrician suit

Electricians must be equipped with winter and summer work clothing. Jackets must have several pockets where you can place small tools: screwdrivers, pliers, etc.

Respirator

Serves to protect the respiratory system from dust or gases. Respirators are equipped with varying degrees of filtration depending on the specific model.

According to the standards, respirators must fit completely to the face, and therefore you need to look for a model that is most suitable for a specific head size.

Mask

Another mandatory piece of equipment that every electrician at an industrial enterprise must be provided with.

A gas mask will be needed if an emergency occurs at work with the release of a substance harmful to the body. Thanks to special filter elements, the human respiratory system will be protected.

Important! The gas mask must be checked regularly and do not forget to change the filters after the expiration date.

Mittens and dielectric gloves

Mittens should be used if rough or heavy work with your hands is to be done; they protect the skin from cuts. If there is work to be done in winter, then electricians should be given gloves and insulation from the inside with fur.

Dielectric gloves

Dielectric gloves protect a person from electric shock. Products are made of rubber and can have different shapes:

• two-toed;
• five-fingered.

According to the manufacturing method, they are divided into seamless and suture. Dielectric gloves are equipped with markings (the explanation can be found in the instructions), which contains information about what voltage they can work with.

Dielectric galoshes

In addition to goloshas, ​​the employee must be given shoes once a year. It should not contain metal fittings. The boots are made from genuine leather because it is non-flammable.

For your information! Galoshes are worn to protect against step voltage.

Check before use

Before each use, the electrician must make sure that the period of the next PPE test has not passed; this information is indicated on special stamps. In addition, an external inspection is mandatory, and if damage to the insulating coatings is detected, the products must be sent for extraordinary testing. Dielectric gloves are additionally checked for leaks by filling them with air and twisting them. If leaks are detected, use is unacceptable.

We pay attention to the correct selection of personal protective equipment depending on the conditions of use, compliance with the frequency and procedure for carrying out inspections or tests. Violations in these matters will cause electrical injuries, including death.

Permission to extend the work order can be transmitted by telephone, radio or by hand to the permitting, responsible manager or work manager, who in this case, with his signature, indicates in the work order the surname and initials of the employee who extended the work order.

Work orders for which work has been completed must be stored for one year, after which they can be destroyed. If accidents, incidents or mishaps occurred while performing work according to the orders, then these orders should be stored in the organization’s archives along with the investigation materials.

3.18. Organization of work by order

The Company has approved a list of works performed by order of an SGE employee with group III, individually in electrical installations.

The order is of a one-time nature, its validity period is determined by the length of the executors’ working day. If it is necessary to continue work, if working conditions or the composition of the team changes, the order must be given again.

In case of breaks in work during the day, re-admission is carried out by the work manufacturer.

The order for work is given to the work contractor and the permitter. In electrical installations that do not have local operating personnel, in cases where access to the workplace is not required, the order can be given directly to the employee performing the work.

Work, the execution of which is provided for by order, may, at the discretion of the employee issuing the order, be carried out according to the order.

Admission to work under orders must be documented in the Work Orders and Orders Logbook.

By order of operational and operational repair personnel or under their supervision, repair personnel in electrical installations with voltages above 1000 V may carry out emergency work lasting no more than 1 hour, excluding time for preparing the workplace.

Small-scale types of work performed during a work shift and permitted to be carried out in the order of routine operation are contained in the approved list of works performed in the order of routine operation in electrical installations with voltages up to 1000V by operational and operational-repair electrical personnel.

Preparation of the workplace is carried out by the same employees who subsequently perform the necessary work.

Work in the order of routine operation, included in the list, is permanently permitted, for which no additional instructions or targeted instruction are required.

The given list of works is not exhaustive and can be supplemented with permission from the head of the organization. The list indicates what work can be performed individually.

Classification of electrical protective equipment

All of them are classified as follows:

• Insulating
• Fencing
• Equipment for working at height
• Accessories
• Shielding

The “model range” itself includes:

• insulating rods of all available types (operational, measuring, for applying grounding);
• insulating and electrical clamps;
• voltage indicators of all types and categories (with incandescent or gas-discharge lamps, non-contact, pulse, etc.);
• alarms for the presence of voltage in the area (non-contact);
• gloves, boots and galoshes with dielectric properties, carpets, insulating stands;
