In any environment where electrical hazards are present, personal protective equipment (PPE) plays a critical role in safeguarding workers. Among the most vital components of PPE in such settings are insulated gloves, also known as electrical insulating gloves. These gloves are specifically designed to protect users from electric shock and are a fundamental safety requirement for anyone working on or near energised electrical equipment.
What Are Electrical Insulated Gloves?
Insulated gloves are rubber-based protective gloves that provide a barrier between the wearer and live electrical components. Manufactured from high-dielectric natural or synthetic rubber, these gloves are capable of withstanding high voltages without allowing electrical current to pass through to the user’s body. They are typically used in conjunction with leather outer gloves and cotton liners, which offer mechanical protection and comfort, respectively.
Standards and Classification
To ensure safety and effectiveness, electrical insulating gloves must comply with international standards. In Europe, IEC 60903 is the standard that governs the requirements for live working — gloves of insulating material. This standard categorises gloves into six classes based on the level of voltage protection they provide:
- Class 00 – Maximum use voltage: 500V AC / 750V DC
- Class 0 – Maximum use voltage: 1,000V AC / 1,500V DC
- Class 1 – Maximum use voltage: 7,500V AC / 11,250V DC
- Class 2 – Maximum use voltage: 17,000V AC / 25,500V DC
- Class 3 – Maximum use voltage: 26,500V AC / 39,750V DC
- Class 4 – Maximum use voltage: 36,000V AC / 54,000V DC
Compliance with Irish Standards
In Ireland, electrical safety and PPE requirements are regulated under the Safety, Health and Welfare at Work (General Application) Regulations 2007, as amended. These regulations require that all PPE, including electrical insulating gloves, be suitable for the task, properly maintained, and compliant with relevant standards.
Ireland adopts IEC 60903 through its membership in CENELEC, making this the recognised standard for electrical insulating gloves. Therefore, gloves and associated equipment that conform to IEC 60903 and bear the CE marking are considered compliant for use in Irish workplaces.
Employers are responsible for ensuring:
- Proper selection of gloves based on voltage class
- Routine inspection and testing (at least every six months)
- Appropriate storage to maintain glove integrity
- Adequate training for users in correct PPE use and maintenance
We supply a wide range of IEC 60903-compliant gloves, testing devices, and storage solutions suitable for use under Irish legislation.
Types of Insulating Gloves
On Substation-Safety.com, several types of insulating gloves are available, including:
- Class 0 Insulated Gloves – 1000V
Suitable for live working up to 1,000V AC. These gloves are ideal for maintenance tasks on low-voltage equipment. - Class 2 Insulated Gloves – 17,000V
Designed for medium-voltage applications, these gloves provide robust protection and flexibility. - Class 4 Insulated Gloves – 36,000V
These are suitable for extremely high-voltage environments, such as those encountered in transmission and substation work.
Each glove type is marked and colour-coded in accordance with IEC 60903, the standard governing insulating gloves for live working in Europe. Users must select the correct glove class based on the voltage exposure risk.
How Insulated Gloves Work
The core function of insulated gloves lies in their ability to resist electrical current. When properly maintained and correctly used, the gloves act as a non-conductive barrier, preventing electrical energy from travelling from an energised source to the human body.
The gloves’ dielectric properties ensure that electrical current does not bridge across the material, making them especially important during maintenance, inspection or repair work on live equipment. To maintain this protective barrier, the gloves must be kept free from damage, contamination and moisture.
Proper Use and Inspection
Using insulated gloves correctly involves more than simply wearing them. Regular inspection and maintenance are essential to ensure their continued effectiveness:
- Visual Inspection: Before each use, gloves should be checked for signs of damage such as cuts, tears, abrasions, punctures or swelling. Any gloves showing visible damage should be removed from service immediately.
- Air Test: Users should perform an inflation test to check for undetected holes or weak points. This involves inflating the glove (either manually or with a testing device) and listening or feeling for escaping air.
- Cleaning and Storage: Gloves should be cleaned with mild soap and water and dried naturally. They must be stored in a cool, dry environment away from direct sunlight, extreme temperatures and sharp objects.
- Periodic Testing: According to IEC 60903, gloves must be electrically tested at intervals not exceeding six months. Testing involves subjecting the gloves to voltage levels higher than their rated use voltage to verify their dielectric integrity.
The Role of Leather Protectors and Liners
Insulated gloves are often worn in combination with leather protectors and cotton liners:
- Leather Protectors: These provide physical protection against cuts, abrasions and punctures, preserving the integrity of the rubber gloves. Importantly, they must be the correct size and used only with the corresponding class of insulating glove.
- Cotton Liners: Liners enhance comfort, absorb perspiration and provide additional warmth in colder working conditions.
It is important to note that leather protectors should never be worn without the insulating gloves beneath them, as they do not offer any electrical protection on their own.
The Importance of Proper Storage
To preserve their insulating properties, gloves must be stored correctly. Environmental factors such as heat, ozone and sunlight can degrade the material, compromising safety.
We offer a range of suitable storage options including:
- Insulated Glove Box – Small
A compact and durable solution designed for storing one pair of gloves. It helps protect gloves from moisture, dust and physical damage. - Insulated Glove Box – Large with Divider
This larger box includes a divider, allowing for the safe storage of both insulating gloves and leather protectors. Ideal for teams or field use.
Proper storage not only extends glove life but also ensures compliance with safety regulations.
Common Applications
Insulated gloves are essential across various industries, particularly where there is regular exposure to electrical systems. Common applications include:
- Utility and Power Generation: Maintenance and repair of substations, overhead lines and switchgear.
- Electrical Installation: Work involving distribution boards, control panels and circuit breakers.
- Renewable Energy: Solar and wind energy installations require the same level of electrical safety as traditional energy sectors.
- Industrial Maintenance: Manufacturing plants and other facilities where electrical machinery is in use.
Conclusion
Insulated gloves are an indispensable part of electrical safety protocols. Their correct selection, use and maintenance can mean the difference between life and death in high-voltage environments. Organisations must ensure that all personnel working with or near energised equipment are equipped with appropriate gloves and are trained in their use and inspection.
While the gloves themselves are only one element of a broader PPE and safety strategy, their role in preventing electrical shock and injury cannot be overstated. We supply a comprehensive range of insulated gloves, storage solutions and testing equipment to support best practices in electrical safety.
