The correct answers are A and D.
Explicación
## Step 1The problem is about safety measures that should be taken before climbing on a scaffold. The options provided are:- 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 2The first option, "Location", is a crucial safety measure. The scaffold should be located in a safe and stable area, away from any potential hazards.## Step 3The 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.## Step 4The 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.## Step 5The 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.
