Your hands are your two most important tools, so you should never work in any industrial environment without the proper protection. Arc flash gloves are some of the heaviest-duty work gloves you can acquire—they’re resistant to abrasions, high temperatures, and vibrations to prevent permanent damage from handicapping you.
Thermal protective gloves are important when you’re working with equipment such as welders, but even in the course of operation, machinery and tools such as electric drills can become hazards due to the amount of heat they generate. Flame resistance helps you avoid careless burns through the course of your work.
Vibrations may seem more innocuous, but long-term exposure to vibrations without arc flash gloves can damage the blood vessels and nervous system, making it difficult for blood to circulate in your hands and causing permanent numbness.
