Safety First: Learn How to Safeguard Yourself During MIG Welding

In the realm of welding, numerous factors can jeopardize your health. It is crucial to be well-informed about the following key points:

Find out some of the ways welding can damage your health or kill you, and how you can protect yourself.

  1. Shield Your Skin Against UV Light:
    • Safeguard every inch of your skin from harmful UV light exposure.
    • Temporary moments of closing your eyes will not suffice in preventing arc eye.
    • Choose to operate in adequately ventilated areas, avoiding extraction fans that may disperse your shielding gas.
  2. Enhance Extraction for Safety:
    • If your extraction setup is inadequate, it is advisable to wear a vapor mask to protect yourself from hazardous fumes.
    • Ensure the absence of flammable materials in proximity, as welding and grinding sparks have the potential to travel considerable distances.
  3. Arc Eye Caution:
    • MIG welding emits an intensely bright light that can lead to arc eye, a condition where the cornea suffers from burns caused by the arc’s intense flash.
    • Even for individuals donning full face welding masks, reflected light can still cause arc eye, particularly when welding in rooms with white painted walls.
    • Additionally, welder’s caps serve a purpose beyond spark protection.
  4. Metal Vapor and its Effects on Health:
    • Engaging in MIG welding and angle grinding exposes you to potentially harmful metal vapors.
    • Certain metal vapors, such as those from aluminum alloy and zinc coatings, possess toxic properties, leading to conditions like heavy metal poisoning.
    • Prioritize the removal of zinc coatings from galvanized steel before welding, and ensure the utilization of a proper charcoal welding mask in zinc-rich environments.
    • Fumes from flux cored gasless wire and ARC welding are also detrimental to health, with stainless steel emitting chromium and MIG/TIG arcs producing ozone.
    • Consequently, it is essential to conduct welding operations in well-ventilated spaces.
  5. Protection from UV Light and Molten Metal:
    • The intense UV content in MIG welding can result in severe sunburns.
    • Wearing protective clothing that covers your arms and legs is paramount, and opting for thin, breathable attire is preferable over exposing bare skin in hot conditions.
    • Welding gauntlets provide essential protection for hands and wrists, while wearing cotton overalls or clothing minimizes the risk of molten metal penetrating gaps and causing burns.
    • Beware that welded metal retains heat for a considerable period; avoid handling hot metal without proper precautions.
  6. Fire Safety Measures:
    • Molten metal and grinding sparks have the potential to travel several feet, posing a fire hazard.
    • Conduct a thorough risk assessment of your surroundings, ensuring a tidy work area devoid of sawdust, paper, or plastic bags that could smolder and ignite.
    • Flame detection might be challenging when viewing through a shade 10 visor; therefore, remain vigilant.
    • After welding or grinding, monitor the workshop for lingering smoldering fires to prevent potential incidents.
    • Keep a fire extinguisher, preferably CO2 type, near the workshop exit. A bucket of sand can serve as an additional fire containment measure.
  7. Angle Grinding Safety:
    • Workshop tools produce high noise levels that can damage hearing. Always prioritize wearing ear protection when operating tools like grinders, hammers, or drills.
    • Invest in high-quality goggles with impact-resistant lenses and without direct air breathing holes for adequate eye protection during grinding.
    • Ensure sparks are directed away from your body while grinding to minimize the risk of injury.
    • Be cautious of fire hazards associated with grinding dust, particularly the combination of aluminum and steel dust, which can burn intensely and act as a welding power source.
  8. Exercise Common Sense:
    • Apply sound judgment and practical reasoning when engaging in welding activities.
    • Note that this guide does not encompass all aspects of welding safety.
    • Seek advice from welding professionals and experienced welders before initiating any welding projects.
    • Additionally, please refer to the comprehensive disclaimer for further information.
