Answer:
A welding arc produces extreme temperatures and can spark fire and explosion hazards if safety procedures are not followed. While the arc itself can reach temperatures up to 10,000 degrees Fahrenheit, the most common cause of fire is when sparks and spatter come in contact with flammable materials around the work area.
Personal protective equipment (PPE) is important for welders because there are hazards when welding, cutting, and brazing. These hazards can include exposure to metal fumes and UV radiation, burns, shocks, cuts, and broken toes.
