What should be confirmed before climbing on a scaffold? a competent person on the ground is holding on to the scaffold the wheel brakes on the scaffold are locked in place __ the path is clear for the scaffold to be rolled into location only composite scaffolds are used when working near electricity lines

## Step 1<br />This problem is about safety measures that should be taken before climbing on a scaffold. The options provided are:<br />- A competent person on the ground is holding on to the scaffold<br />- The wheel brakes on the scaffold are locked in place<br />- The path is clear for the scaffold to be rolled into location<br />- Only composite scaffolds are used when working near electricity lines<br /><br />## Step 2<br />The first option, "A competent person on the ground is holding on to the scaffold", is not a necessary safety measure. This is because the scaffold should be stable and secure, and a person on the ground holding onto it does not contribute to its stability.<br /><br />## Step 3<br />The second option, "The wheel brakes on the scaffold are locked in place", is a necessary safety measure. This is because the scaffold should be stable and secure, and the wheel brakes being locked in place ensures that the scaffold does not move while in use.<br /><br />## Step 4<br />The third option, "The path is clear for the scaffold to be rolled into location", is also a necessary safety measure. This is because the scaffold should be able to be moved into position safely, and a clear path ensures that it can be done so without any obstacles.<br /><br />## Step 5<br />The fourth option, "Only composite scaffolds are used when working near electricity lines", is not a necessary safety measure. This is because the type of scaffold used should be determined by the specific requirements of the job, not the proximity to electricity lines.
