Introduction
Musculoskeletal Disorders (MSDs)
A musculoskeletal disorder (MSD) is when there is some sort of damage to a part of the musculoskeletal system.

Introduction
Now that we understand what our musculoskeletal system consists of, we need to know how work places demands on these parts of our bodies.

Physical Demands
Main Criteria:
Force and Contact StressRepetitionFixed or awkward body positionsEnvironmental Factors
![Page 14: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/14.jpg)

Physical Demands
Force:
When you exert pressure on something, pressure is placed back onto your body.
![Page 15: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/15.jpg)

Physical Demands
Contact Stress
Contact between the body and hard or sharp work objects.
Stress intensifies with• Little padding• Small contact area• Long duration
![Page 16: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/16.jpg)

Physical Demands
Repetition:Repetition – using the same body parts without giving them a chance to rest
Repetition is defined using three variables:• Frequency• Duration• Intensity
Movements are bundled into cycles

Physical Demands
Posture:
Posture simply refers to body positions
Posture falls into two categories:• Good, or “ideal”• bad or “awkward”

How Injuries Occur
Musculoskeletal Disorders (MSDs)
Development• Cumulative Loading - slowly (weeks, months or
years).– Wear and tear over time
• Peak Loading – After a single particularly taxing event.– One time exertion

Where to begin?
Now that we know the basic way in which physical demands are placed upon individuals, and how injuries occur, we just need a tool to help guide our assessments.

HSE’s Approach
Risk filters exist for various Manual Handling activities:
Lifting, Lowering, and Carrying
Pushing and Pulling• Guidance based on load weight being pushed• Should be altered for slope
Seated handling• Different guidance values for men and women
![Page 38: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/38.jpg)

HSE’s Approach
Step 1: Use of Risk Filters. This is the filter for lifting tasks.
![Page 39: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/39.jpg)

HSE’s Approach
Reduction of lifting lowering limits due to twisting and high frequency activities
Twisting:• reduce limits by 10% if
twisting 450 or more,
• reduce limits by 20% if twisting 900 or more

Page 41 of 81
HSE’s Approach
The use of risk filters should not be considered lifting/carrying/pushing/pulling limits!
These are only used to differentiate between high risk and low risk activities. This will help you use your time more wisely.
Once the high risk activities are taken care of, you should go back and try to improve the other activities.
![Page 42: Working Through the Risks of Manual Materials Handling](https://reader034.fdocuments.us/reader034/viewer/2022052410/546d4943b4af9f6b2c8b52f5/html5/thumbnails/42.jpg)

Step 2: Complete a full assessment.
Part of the full assessment can be done with the MAC tool:Step 1: Load and FrequencyStep 2: Posture:
• Arm distance• Trunk twisting and asymmetry
Step 3: Room to moveStep 4: GripStep 5: Environment

What do they do?
Work with government, employers and workers to promote risk prevention culture.
Analyze scientific research and statistics on workplace risk
Anticipate new and emerging risks
Identify and share information, good practices, and advice.

Assessment methodology similar to HSE’s approach
• Perform a screening assessment – observational prioritization.
• Perform a more in depth assessment for activities that are high risk in the screen assessment.

Time Rating Calculation
Calculation based upon 1 lift every 9 – 14 seconds• = average of 1 lift every 12 seconds.• = 5 lifts per minute • = 600 lifts in 2 hours.• Rating = 500 to 1000 pieces per day = “8”
