What is Manual Handling?

“Any transporting or supporting of a load (including the lifting,

putting down, pushing, pulling, carrying or moving thereof) by hand or bodily

force.”

Principles of Safe Handling.

If Manual Handling Operations cannot be avoided then apply the principles of safe handling:

Assess: Load

Assess: Task

Posture Frequency Duration Intensity Pacing Team Handling Rewards


Assess: Individual

Strength Height Pregnancy Health Training Experience Gender Age


Assess: Environment

Space constraints Floor condition and levels Temperature Humidity Ventilation Lighting Noise Housekeeping


Plan: Route.

Consider start and end points.

Are there doors or steps on the route?

Any obstructions to be cleared?

Are there vehicles or other persons to be aware of?


Plan: Task

Consider the most appropriate postures.

Is there mechanical equipment available?

Is there anybody that can help?

Is PPE being worn correctly?


Prepare: Yourself.

Get a good grip of the load. Use PPE when necessary.

Principles of Safe Handling.Prepare: Load

Can the load be split? Make the load stable. Pack shifting contents

tightly. Evenly distribute contents. Keep the centre of gravity

of the load close to you. Cover sharp abrasive

edges.

Prepare: Area

Clear area of obstacles. Warn people. Check destination. Ensure good lighting. Check housekeeping.



Perform: Apply principles of biomechanics to reduce the loading on

the spine Keep a wide base of support. Maintain the lumbar curve (low back) as much as possible. Brace yourself Get a good grip. Position feet in direction of travel. Use smooth controlled movements. Use friction to minimise force. Try to avoid twisting and stooping. Use team lifting where appropriate.
