Have you ever wondered how risky working with high-voltage electrical systems is due to arc flash hazards? Choosing to use Arc Flash leather gloves in conjunction with properly rated electrical safety gloves is the best way to prevent danger. The company SCMA offers professional technical solution services for your highest safety needs. This article will introduce you to this piece of PPE equipment in detail, so that you can use it correctly and safely, reducing losses during work.
What are Arc Flash Leather Gloves?
Arc Flash leather gloves are heavy-duty leather gloves designed to be worn over rubber insulating electrical gloves. This type of equipment serves as a protective layer against heat from arc flash, which occurs when high-voltage electricity arcs through the air. Wearing arc-resistant gloves will effectively protect your hands from intense heat, light flashes, explosive forces, and even flying metal debris.
Why Use Arc Flash Leather Gloves?
This PPE equipment for electrical work is crucial in protecting workers from severe hazards. The main reasons why every electrician must wear this type of gear along with rubber insulating gloves are as follows:
To Prevent Rubber Insulating Gloves From Being Cut
In real working conditions, there is always a risk that equipment may be cut by sharp objects or punctured. Wearing leather gloves over rubber gloves will effectively prevent abrasion or tearing. This method helps maintain the electrical insulation standards of the inner rubber gloves perfectly.
To Protect Against Heat and Sparks
Real leather gloves have special properties to withstand high heat, resist fire, and not melt when exposed to arc flash sparks. These Arc-rated properties stand out distinctly from regular cloth or rubber gloves, ensuring workers are safe from intense heat during electrical faults.
To Reduce the Severity of Melting Burns
In case of an explosion, high temperatures may cause synthetic materials to melt and stick to the skin, causing severe injuries. Arc Flash leather gloves act as a barrier preventing melted rubber pieces from directly contacting the hands. Using this equipment significantly reduces the severity of burns.
How many types of Arc Flash Leather Gloves are there?
The leather gloves designed to protect against arc flash in the current market come in various designs suitable for different working conditions. We can categorize these gloves into two main types based on their usage.
Over-Gloves (Leather Protector Gloves)
This type of glove is specifically designed to be worn over rubber insulating gloves. Its primary function is to prevent abrasion, protect against sharp objects piercing through, and shield from the heat of electric arcs. Wearing these over-gloves helps preserve the inner electrical PPE for a longer period.
Full Liner Arc Flash Gloves
This type of glove is lined with flame-retardant materials to protect against high levels of heat, such as Aramid or Kevlar. The gloves are suitable for work environments with a very high risk of severe arc flash incidents. Users can choose the level of thermal energy protection according to various standards ranging from 12 Cal/cm² up to 100 Cal/cm².
How to Maintain Arc Flash Leather Gloves
Proper maintenance helps extend the lifespan and maintain the highest level of safety performance. Based on the experience of the SCMA engineering team, we recommend the following care steps.
Cleaning After Use
The user should gently brush off dust and debris from the gloves with a soft-bristled brush before cleaning each time. Then use a damp cloth with normal temperature water to clean any stains on the arc flash-resistant leather gloves. If there are stubborn stains, use a slightly soapy cloth to clean only those areas. Do not use bleach under any circumstances.
Maintenance and Drying
Regularly applying leather conditioner or oil will help restore flexibility and prevent the leather from becoming stiff and brittle. After cleaning, air dry in a shaded area with good ventilation; do not expose to direct sunlight or place near heat sources as this can cause the leather to shrink and deteriorate.
Proper Storage
The storage location for arc-resistant gloves should be cool and dry, avoiding areas directly exposed to sunlight. Store them flat on a surface without folding, bending, or placing heavy objects on top of them. Remove the inner rubber insulating gloves before storing to prevent moisture buildup inside.
Pre-Use Inspection (Inspection)
Before each use, check for any tears, abrasions, burns, or if the leather has become stiff and brittle. If the leather is deteriorated or damaged, replace with a new pair immediately to ensure safety during work. The inner rubber gloves must also be tested for electrical withstand voltage at regular intervals as specified.
Proper Use of Arc Flash Leather Gloves
The correct use of leather arc flash gloves is crucial for preventing electrical hazards. Workers must strictly follow the safety standards' usage guidelines.
Preliminary Equipment Inspection
Begin by checking the leather gloves to ensure there are no cracks, burn marks, oil stains, or moisture. Damaged PPE equipment for electrical work cannot provide full protection against hazards. Conducting a pre-use inspection every time helps reduce on-site accident risks.
Wear Insulating Rubber Gloves First
Always wear insulating rubber gloves as the first layer. Users must check for leaks in the electric shock-resistant gloves by inflating them and ensuring they are within their expiration date. This step is crucial because rubber gloves form the primary barrier against electrical current.
Wear Leather Gloves Over Rubber Gloves
Put on arc flash leather gloves over the rubber gloves as the second layer. Pull the leather glove cuffs down to cover at least one inch beyond the edge of the rubber gloves. Do not pull the leather gloves up to completely cover the top edges of the rubber gloves, to prevent electrical short circuits across the leather.
Cleaning and Storage
Upon completion of work, immediately clean dust or dirt with a cloth. Remove both layers of protective equipment separately for ventilation to prevent moisture buildup. Store in a dry, safe place away from direct heat and sunlight to extend their lifespan.
Benefits of Arc Flash Leather Gloves
Investing in high-quality safety equipment positively impacts employee safety. Arc flash leather gloves offer distinct advantages to users as follows:
Non-flammable and Do Not Melt When Exposed to Heat
The high-quality leather material combined with flame-resistant fibers provides excellent heat resistance. In the event of extreme heat, these materials will not drip, melt, or ignite. Therefore, arc flash gloves serve as a frontline defense against scalding burns.
Prevent Inner Gloves from Being Cut
The industrial workplace is filled with sharp tools, metal edges, and debris that may cause harm. Leather gloves worn over rubber inner gloves will absorb impacts and abrasions instead of the insulating rubber gloves, thus protecting them from cuts or punctures during work.
High Heat and Energy Resistance
These electrical safety devices are specifically designed to withstand high-arc heat. The gloves can handle thermal energy levels ranging from 32 to 48 Cal/cm², depending on the model. Having a standardized heat-resistant barrier builds confidence in workers.
Durable and Long-lasting
The stitching structure of leather gloves emphasizes strength and durability against abrasion and punctures. Standardized products undergo testing according to ASTM F696 standards for electrical protection. Choosing durable equipment helps reduce the cost of frequent replacement.
How to Choose Arc Flash Leather Gloves
Selecting PPE equipment for electrical work requires considering features that are appropriate for the job site risks. You can use the checklist below as a guide when choosing standard-compliant leather Arc Flash gloves.
- Check the Arc Rating (ATPV): Assess the risk level of the job site to determine how many calories of arc flash could occur in the electrical system, and choose gloves with an Arc Rating higher than the assessed risk.
- Verify Safety Standards: The product must be certified under ASTM F2675 for Arc Flash hazard protection or study reliable sources such as Superior Glove regarding durability testing.
- Select a Style That Meets Your Needs: If you will be handling high voltage, choose gloves to wear over rubber gloves. For higher dexterity, opt for models made with lightweight heat-reflective materials.
- Material Quality: Choose Arc Flash gloves made from cowhide for durability or goatskin for better finger movement flexibility.
