MEWP rescue plan – This represents the Mobile Elevated Working Platform (MEWP) rescue plan.
Most equipment are built with an in-build safety measures to ensure the safety in the use of the equipment as much as possible. However, things still go wrong.
Since no system operation can boast of 100% safety, there must be an emergency measures put in place in case something go wrong. This is where the MEWP rescue plan comes in.
Main aim of MEWP rescue plan
The aim of this MEWP rescue plan is to bring the occupants of the aerial platform to the ground safely. Therefore, all measures adopted must ensure the safety of the occupants of the aerial lift.
Need for rescue
Occupant(s) of the MEWP may need to be rescued in one or more of these situations:
- Operator incapacitation
- Occupant injury
- Snagged platform
- Platform overload
- Mechanical malfunction, etc.
MEWP in-built safety measures
Aside from the normal controls, the MEWP also have auxiliary controls which could be used if the normal control fails.
The MEWP have:
- Normal upper control (From the basket)
- Auxiliary upper control
- Normal ground control
- Auxiliary ground control
It is only when all the above measures have been exhausted and attempt of repair fails that the MEWP rescue comes into play.
Any situation which prevents the platform being lowered to the ground by the operator using the normal controls, there will be needs for a clear plan to bring the platform and occupants safely to the ground in a timely manner.

How to plan MEWP rescue
- Ensure ground key is always available on ground
- Ensure all MEWP operators are trained and fully familiarised
with the MEWP (including use of auxiliary controls) and the
work to be performed.
- Communicate the MEWP risk assessment and safe method of work to everyone involve with the use of the MEWP.
- Familiarise qualified persons on the ground or working near
the individual MEWP with the ground controls and allow
them to practice lowering the raised platform.
- Identify a qualified personnel who can assess the emergency situation to identify risk and determine risk level.
The qualified personnel is to determine:
– Possible causes of the situation
– If persons in the platform need medical attention and the urgency.
– If all occupants in the raised platform secure where they are
– If there is any reasons why the occupants should be lowered
as a matter of urgency – e.g. excessive winds, lightning storm
Once the situation has been assessed an appropriate action
plan can be implemented to recover the situation.

MEWP rescue chain of actions
This rescue plan is activated when the normal upper control function fails. Here are the steps to follow:
- Normal ground control should be attempted; if it fails
- Use the upper auxiliary control; if it fails
- Try the ground auxiliary control; if it fails
- Try onsite repair if available; if it fails, then,
- Use the mid-air rescue (Basket to Basket rescue)
Note: All ground actions must be undertaken by the appointed rescue person.
If you have noticed the chain of events, it is recommended that auxiliary control should only be used if both upper and ground normal control fails if occupants needs fast rescue. This is because, auxiliary control takes long to return the aerial platform to the ground, thereby slowing the speed of rescue.
Safety precautions when using the mid-air rescue (Basket to Basket rescue)
Basket to basket rescue can be complicated and pose additional health and safety risks so it is important to follow safety precautions when carrying it out.
Some safety precautions:
- The rescue machine should be placed in the safest position to minimise any additional danger to anyone involved in the rescue
- The two machines should be placed adjacent to each other with the smallest possible gap between them.
- Attach a double lanyard to the person being rescued to provide anchorage on both machines before the rescue takes place.
- Never overload the rescue machine as this could lead to over-tipping or delay the rescue operation
Note: Where a basket-to-basket rescue is not feasible, crane rescue could be used.
Example of MEWP rescue plan
|S/N||EMERGENCY SITUATION||PROPOSED ACTIONS|
|1||Failure of upper control functions while elevated||Where the normal upper control functions fail; the operator will use the upper auxiliary controls to lower the platform safely.|
|2||Failure of the operator to be able to operate the MEWP functions while elevated due to one of the following reasons:
A. Operator incapacitated
B. Both normal and auxiliary functions fail to operate from upper control station
|Where the operator is incapable of lowering the raised platform using the upper controls; an appointed person familiarised in the use of the ground controls will lower the platform safely using the normal ground controls.|
|3||Failure of normal ground controls||Where the normal ground controls fail; an appointed person familiarised in the use of the ground controls will use the ground auxiliary controls to safely lower the platform.|
|4||Failure of ALL normal and auxiliary lowering functions||Where all normal and auxiliary functions have failed a qualified person, and a service technician should be contacted.|
