The correct answer is 'C'.
Explicación
## Step 1The problem is asking us to identify the correct safety precaution to take when welding on containers that previously held combustible materials. The options provided are:A. Weld quickly to minimize heat exposureB. Use only low amperage settingsC. Clean and formally verify safety or use inerting processD. Keep a fire extinguisher nearby only## Step 2We need to evaluate each option based on its effectiveness in ensuring safety during welding on containers that previously held combustible materials.## Step 3Option A suggests welding quickly to minimize heat exposure. However, this does not address the potential risk of igniting the combustible materials in the container.## Step 4Option B suggests using only low amperage settings. While this may reduce the heat generated, it does not eliminate the risk of igniting the combustible materials.## Step 5Option C suggests cleaning and formally verifying safety or using an inerting process. This is a comprehensive safety measure that involves cleaning the container to remove any residual combustible materials and verifying the safety of the welding process. This is the most effective safety precaution among the options provided.## Step 6Option D suggests keeping a fire extinguisher nearby only. While this is a good safety measure, it does not address the potential risk of igniting the combustible materials in the container.
