Session 2 - Ergonomics and Risk Assessment



Ergonomics

Introduction to ergonomic theory

All students have undertaken an Ergonomic Practical Session with the Physiology Laboratory

This has identified the flexibility and strength of the spine and body and considered the following individual differences:

We must be aware of the following issues in relation to moving and handling in the caring environment:

Handling and Injury (source: Health & Safety Executive, 1992)

Pressure put on the spinal cord is called the load, the increase in load will depend on the position of your body.

It is therefore important that we consider our posture at all times for the health of our spine but especially when we are moving the patients.

We can see from the following graph how position can alter the load.

Causes of back pain

Primary

Results from the damage to the soft tissue around the spine from:

Secondary

Results from interference with the spine nerves, from:

Referred

Pain originates not in the spine but in the pelvis, or abdomen, which have the same segmental nerve supply.


The effects of ageing

The spine is still growing and developing up to around the age of eighteen. Up to this point both the spine and the general musculature are usually unfamiliar with the stresses and strains of prolonged manual work.

As we get older, other factors come into play. Whilst the spine is fully developed once people reach adulthood, the ageing process continues and can precipitate weakness both in the skeleton and musculature. Usually, after the age of fifty five, the average level of degeneration in the skeleton significantly increases the risk of injury during manual handling.


Chemical and biolgical factors

  • increases in weight

  • relaxation of ligaments surrounding the pelvis

Forward bending Side bending Rotating Extending

These are examples of not keeping the body in normal alignment.


Intervertebral discs

The function of the disc is to act as a "shock absorber".

If the pressure on the disc is too great it will herniate - pain may be felt and nerves trapped.

Risk Assessment

What is a risk assessment?

Firstly, assessing risk means being aware of the problem areas. It then helps determine how concerned you need to be about the problem. For instance, does it place many staff at risk? Is the problem met frequently or rarely? Is it likely to cause a major injury, or could it be one of the many tasks where each time it is carried out it contributes to cumulative strain? But a risk assessment is useless unless it leads to action on reducing risks. This could be an immediate decision to change a simple work practice, or it could be the basis for budgeting over several years to purchase a large number of handling aids.

 Why do risk assessments? - THE REGULATIONS REQUIRE IT!

The Manual Handling Operations Regulations 1992 require risk assessments to be carried out if the employer cannot avoid the need for a manual handling which involves a risk of injury. Once assessments are made, the employer must take appropriate steps to reduce the risk of injury to the lowest level reasonably practicable. "Reasonably practicable" means reducing the risk until the cost of any further precautions - in time, trouble or money - would far outweigh the benefits.

Levels of Risk Assessment

There are three levels of assessments:

Assessments should be developed so that the patient care plan contains clear information on the patients movement, abilities and needs. Where necessary to include specific instructions for the use of lifting aids.

An assessment at ward level only needs to be done occasionally (annually).

Whenever senior management considers the requirements of the organisation:


An example of a Risk Assessment tool

RULA:

This assessment method was developed by Ms Lynn McAtamney, Institute of Occupational Ergonomics, University of Nottingham.

This method of observation is broken down into a number of key areas; upper arms, lower arms, wrists and neck twist, trunk, leg muscle use and forces or load score.

A variety of different scores are given depending on the angle of bend, the angle of twist, loads or forces applied and muscles use either static or repetitive.


Elements of a Risk Assessment

Task

Individual Capability

Load

Working Environment

We often refer to TILE


Checklist for assessing risks

THE LOAD

Heavy, bulky or unwieldy?

Asymmetrical?

Unstable or could move suddenly?

Texture/temperature/sharp corners?

Difficult to grasp?


POSTURE AND MOVEMENT

Holding Loads away from the body?

Twisting and/or stopping?

Reaching upwards?

Large vertical movement (eg floor to overhead)?

Long carrying, pushing, hand/limb position grip?

Fatiguing, strenuous?

Restrictions on posture from clothing/uniform?


DURATION, FREQUENCY AND JOB DESIGN

How long, how often?

Fixed, static work

Repetitive? Forced pace?

Sufficient rest or recovery time?

Are there other tasks the worker does which may load him/her further?

Is the task always done by the same worker / is there job rotation?


THE WORKING ENVIRONMENT

Enough room to move freely in good posture?

Provision for alternative working positions/seats?

Machinery/workbench at a convenient height?

Is the floor slippery/uneven/littered?

Lighting adequate?

Too hot, too cold, draughty?

RCN Guide 1996


Client handling criteria

CLIENT HANDLING CRITERIA WILL ALWAYS TAKE INTO ACCOUNT

  1. The client’s condition.
  2. Any attachments he or she might have.
  3. Any special problems.
  4. The client’s ability to assist in the procedure.
  5. Whether the client can be moved without causing pain.
  6. The condition of the client’s skin with regard to contact points needed during the manoeuvre.

WHEN CONSIDERING WAYS IN WHICH A CLIENT MAY BE INJURED DURING A TECHNIQUE THERE ARE FOUR MAIN POINTS:

  1. Friction
  2. Joint damage
  3. Resistance from the client
  4. Falls

Analysis of a repetitive task

Just Suppose:

For 6 dependent patients

Total weight moved is 6,720lbs

or

3 tons

or

120 sacks of potatoes

IS THIS REASONABLE?
