The correct answer is D. Using oxygen to blow off the workpiece.Explanation:A. Using a fire-resistant blanket to cover flammable materials is a recommended practice for fire prevention in SMAW (Shielded Metal Arc Welding) welding. It helps to contain any sparks or flames that may occur during the welding process.B. Confirming that metal scrap is cold before disposal is also a recommended practice. This ensures that there are no hot materials that could potentially ignite and cause a fire.C. Ensuring that a valid fire extinguisher is nearby is another recommended practice. In case of a fire, it is crucial to have a fire extinguisher readily available to quickly put out the fire.D. Using oxygen to blow off the workpiece is NOT a recommended practice for fire prevention in SMAW welding. Oxygen can actually increase the risk of fire and should never be used in this context.
