When performing plasma -arc cutting near a battery, the operator should remove the battery to prevent which of the following? electrocution leakage of lead from the battery the release of carbon monoxide into the work area a hydrogen gas explosion caused by a cutting spark

## Step 1<br />The problem is about the safety precautions to be taken during plasma-arc cutting near a battery. The operator should remove the battery to prevent certain hazards.<br /><br />## Step 2<br />The first option, "electrocution", is a potential hazard when performing plasma-arc cutting near a battery. This is because the cutting process can create a spark, which can lead to electrocution if the operator is in contact with the battery.<br /><br />## Step 3<br />The second option, "leakage of lead from the battery", is not a direct hazard from the plasma-arc cutting process. However, it is a potential hazard from the battery itself, especially if it is a lead-acid battery.<br /><br />## Step 4<br />The third option, "the release of carbon monoxide into the work area", is not a direct hazard from the plasma-arc cutting process. However, it is a potential hazard from the battery itself, especially if it is a lead-acid battery.<br /><br />## Step 5<br />The fourth option, "a hydrogen gas explosion caused by a cutting spark", is a potential hazard from the plasma-arc cutting process. This is because the cutting process can create a spark, which can ignite the hydrogen gas produced by the battery.
