Abrasion-resistant gloves protect hands from friction and wear during tasks involving rough surfaces or abrasive materials. These gloves are commonly used in construction, manufacturing, and other physically demanding jobs. Materials like:

Leather: Provides good abrasion resistance and durability, but it can be stiff and less dexterous.
Kevlar®: Offers excellent abrasion resistance and high tensile strength.
Canvas: Provides a good level of abrasion resistance, but it's less durable than leather or Kevlar®.
Synthetic materials: Many synthetic materials offer varying levels of abrasion resistance, often combined with cut resistance.

The selection of abrasion-resistant gloves depends on the specific task and the level of abrasion expected. Heavier gloves offer greater protection but can reduce dexterity.

4. Heat-Resistant Gloves: Protection from Thermal Hazards

Heat-resistant gloves protect hands from burns and scalding caused by hot objects or materials. These gloves are vital in industries such as:

Foundries: Handling molten metal.
Welding: Protecting against sparks and hot metal.
Cooking: Protecting hands from hot surfaces.

Materials used in heat-resistant gloves include:

Leather: Offers good protection against moderate heat.
Aramid fibers (Nomex®, Kevlar®): Provide excellent protection against high heat and flames.
Silicone: Offers good heat resistance and flexibility.
Aluminized materials: Reflect heat away from the hand.

The selection of heat-resistant gloves depends on the temperature level and type of heat hazard. Always check the manufacturer's specifications to ensure the gloves are rated for the appropriate temperature range.

5. Anti-Vibration Gloves: Reducing Hand-Arm Vibration Syndrome (HAVS)

Prolonged exposure to vibrations can lead to Hand-Arm Vibration Syndrome (HAVS), a serious condition affecting blood vessels and nerves in the hands and arms. Anti-vibration gloves are designed to mitigate the transmission of vibrations from tools to the hands. They typically incorporate:

Specialized padding: Absorbs and dampens vibrations.
High-density materials: Reduce vibration transmission.

Careful selection of anti-vibration gloves, appropriate for the specific tool and vibration level, is crucial in preventing HAVS.
