Transcript of Safe Lifting & Material Handling

Understand & Assess Before You Act
Look at the BIG Picture
How the Back Works
Waist acts as a fulcrum
Ten to one ratio (at lumbar)
Factor in upper body weight
Types of Injuries
Spinal Conditions
Common Causes of Back Injuries
Awkward positions
Slipping or falling
Safe Lifting & Material Handling
Technique is just the Tip of the Iceberg
The spine has 25 joints connecting the 33 individual bones.

Each bone is called a vertebra and grouped to perform specific tasks

Vertebrae are kept separate by discs of cartilage giving the spine flexibility.

Cartilage prevents the vertebrae from grating against each other.

In neutral posture the spine has a natural S shaped curve.
Takes strain during lifting
Each carry a pair of ribs
Supports the skull
The Spine
4 Fused Bones that only move during pregnancy
A poor lifting technique can lead to:
Muscle strains

Vertebrae can shift or become dislocated

Discs can collapse or become herniated

Bone spurs can develop over time
The Spine
How the back works
Types of injuries?
Common causes of back injuries
Safe Lifting Technique
Material Handling Techniques
We will cover
105 lbs
10 lbs (box) + 105 lbs (trunk) = 1150 lbs force on lumbar
10 lbs
Total Force
Poor physical condition
Poor posture
Extra weight
Sitting or Standing
Excessive Stress
Overdoing it
Not All Factors involve the lift
Use handles or holds when available.

Ask for help or consider mechanical assistance with objects >50 lbs.

Reverse the process when lowering the object.
Proper Lifting Technique
Material Handling Techniques
Pushing an object:
Crouch down
Hands at chest level, lean in and push with legs
An alternate form of pushing uses the surface area of the back while still using leg muscles
What are the PROs of Safe Lifting?
What are the CONs of Unsafe Lifting?
Can you use any lifting aids or buddy-system?

You are not the only one who gets hurt.

Identify the hazard to prevent a future injury to someone else.

Your legs have larger muscles than your arms. Use that to your advantage!
Avoid pulling whenever possible
Use Material Handling Aids
Think about what you are about to lift and determine the best course of action.
Take a shoulder-width stance and test lift an edge to judge the weight of the object.
Back Remains
Keep Elbows Close to your body for optimal strength
Use PPE if
Stand Up
Continue to look forward when walking
Lean larger objects against
Use a Forklift or Pallet Jack when object allows for it.
3 Ton
Dolly for Boxes, Cylinders, Drums
Jung Dolly
Hydraulic Cart
5 Fused Bones
Coccyx or
Buddy Lifts for Heavy Objects
Squat down and bend at the knees not the back.
Stand up slowly.
Long Beams or Pipes
Large Objects
1) Start with a Dual Lift
2) Raise to secondary level
3) Reposition and Lift
Lifting Zones
Power Zone - optimal strength
Lifts within semi-circle from shoulders to knuckles.
Elbows kept at your sides
Max of a 50 lbs in a 10" box according to NIOSH equation

Danger Zones - lowered strength
Lifts above shoulders
Lifts below knees
Lifts with arms/elbows extended forward
