Which of the following is not required when welding?

• A. Fire extinguisher
• B. Filter lenses
• C. Oxygen to blow off work and clothes
• D. Mechanical ventilation

Answer: (C)

When welding, safety measures focus on preventing fire, protecting the eyes, and controlling fumes. Using oxygen to blow off work and clothes is not required and can be dangerous because oxygen can feed fires and cause rapid ignition near hot metal, sparks, or flammable materials. Instead, rely on proper housekeeping, appropriate cleaning methods, and ventilation. Oxygen isn’t necessary for cleanliness or drying; use safe cleaning methods (like dry rags or compressed air where appropriate) and ensure good ventilation to remove fumes. Keeping a fire extinguisher on hand is important due to sparks and molten metal. Filter lenses protect the eyes and face from the bright arc and radiation. Mechanical ventilation helps remove hazardous fumes, especially in confined spaces.
