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

## Step 1<br />The problem is about safety measures that should be taken before climbing on a scaffold. The options provided are:<br />- Location<br />- Only composite scaffolds are used when working near electricity lines<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 /><br />## Step 2<br />The first option, "Location", is a crucial safety measure. The scaffold should be located in a safe and stable area, away from any potential hazards.<br /><br />## Step 3<br />The second option, "Only composite scaffolds are used when working near electricity lines", is not a general safety measure. The type of scaffold used depends on the specific requirements of the job, not the proximity to electricity lines.<br /><br />## Step 4<br />The third option, "A competent person on the ground is holding on to the scaffold", is not a standard safety measure. While it's important to have someone on the ground to assist if needed, they should not be physically holding onto the scaffold.<br /><br />## Step 5<br />The fourth option, "The wheel brakes on the scaffold are locked in place", is a critical safety measure. The scaffold should be stable and secure before anyone climbs on it, and the wheel brakes should be locked in place to prevent any accidental movement.
