Rescue Procedures Flashcards

What is an 'entrapment' on a MEWP and why is a rescue plan important?

Answer: When the operator in the platform cannot lower themselves — a rescue plan ensures a safe, fast response to extract them

Entrapment occurs when the operator in the platform cannot lower themselves — due to incapacitation, mechanical failure, or obstruction. Without a rescue plan, the person remains at height with no means of descent.

What are the two primary methods of rescuing an entrapped MEWP operator?

Answer: Ground-level emergency lowering using the base controls, or aerial rescue using another elevated platform or ladder

The two primary rescue methods are: ground-level emergency lowering using the machine's base emergency controls (the preferred method), or aerial rescue where another elevated means is used to reach the operator.

Before operating a MEWP, what rescue information must every operator know?

Answer: The location and operation of the ground-level emergency lowering controls and the site's rescue procedure

Every operator must know the location and operation of the ground-level emergency lowering controls and the site's specific rescue procedure before ascending. This knowledge enables rapid response if entrapment occurs.

What is the role of a 'dedicated competent observer' during MEWP operations in risk areas?

Answer: To monitor the operator and machine from ground level, and to initiate rescue immediately if entrapment or emergency occurs

In areas with higher risk — such as near traffic or in complex environments — a dedicated competent observer monitors the MEWP operator and is ready to initiate rescue immediately if the operator becomes entrapped or incapacitated.

Why should a MEWP operator always wear a harness with a lanyard attached to the designated anchor point?

Answer: To prevent being ejected from the platform in the event of a sudden jolt, collision, or platform failure

A harness with a correctly attached lanyard prevents the operator from being thrown out of the platform if the MEWP jolts, is struck, or partially fails. Ejection from a MEWP at height is frequently fatal.

What is 'suspension trauma' and why is it relevant to MEWP rescue?

Answer: A potentially life-threatening condition caused by hanging in a harness for too long — rescue must be rapid and the casualty treated carefully when lowered

Suspension trauma occurs when blood pools in the legs during vertical suspension in a harness, reducing blood flow to vital organs. It can be fatal within minutes. MEWP rescues must be rapid, and the person must not be laid flat immediately.
