Ergonomics and Risk Assessment



Ergonomics

ERGONOMICS ~ study of workplace design: 

 The study of how a workplace and the equipment used there can best be designed for comfort, safety, efficiency, productivity and fitting the job to the person and with the design of safe systems of work. 

[Mid-20th century. Coined from Greek ergon "work" on the model of economics.]

Ergonomic Principles applied to Moving and Handling

         Base Movement

                mobility with stability

         Relaxation of the Hips & Knees

enabling use of leg power

         Natural Spine shape

vertical position ~ avoid twisting

~ head leads movement

         Hold

         Use of Body Weight

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.

Posture (source: Dr. Vic Weatherall,  www.advancechiro.on.ca)

Posture is essentially the position of the body in space. Optimal posture is the state of muscular and skeletal balance that protects the supporting structures of the body against injury or progressive deformity, whether at work or rest. Correct posture involves the positioning of the joints to provide minimum stress on the joints of the body. 

 Faulty posture increases stress on the joints. Strong muscles can compensate for this increased stress, but if they are weak or the joints lack mobility or are too mobile joint wear, damage and changes to the surrounding tissues can occur. 

The effects of posture can be far reaching, involving respiratory, digestive, and circulatory systems as well as the musculoskeletal system. But how is poor or faulty posture developed? 

Causes of poor posture 

The causes of poor posture can be divided into two categories: positional and structural. Structural causes are basically permanent anatomical deformities not amenable to correction by conservative treatments. Positional causes of poor posture include ~

        poor postural habit--for whatever reason, the individual does not maintain a correct posture. 

       psychological factors, especially self-esteem. 

       normal developmental and degenerative processes. 

       pain leading to muscle guarding and avoidance postures. 

       muscle imbalance, spasm, or contracture. 

       respiratory conditions. 

       general weakness. 

       excess weight. 

       loss of the ability to perceive the position of your body. 


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


The spinal column

  • The spinal column is composed of 33 protective vertebrae, providing attachments for ligaments, muscles and ribs. Click on picture of spine.

  • The spinal column and cord components are a unique design. For good posture, the spine needs to be maintained in normal alignment. The following movements should be avoided:

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.

Any procedure carried out that involves moving anything must be risk assessed and reduced as far as reasonably practicable (see Legislation).  Proper risk assessments should identify the safest handling method, the equipment, environment and technique must reduce the risk to the lowest level reasonably practicable (BackCare & RCN, 1998).

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:


Risk Assessment Tools

There are a variety of Risk Assessment or Ergonomic Tools in use, examples are:

 RULA:         Rapid Upper Limb Assessment.

OWAS:         Ovako Working posture Analysis System.

 REBA:         Rapid Entire Body Assessment.

 These are used to analyse posture as an element of an ergonomic workplace assessment. 


Checklist for assessing risks

To assess risk before commencing a Moving and Handling task, the commonly used risk assessment tool is TILE. 

 Problems to look for when making an assessment are:

Task              Does the task involve ~

         unpredictable movement of the load?

         twisting, stooping or stretching?

         holding the load away from the trunk?

         repetitive handling

         strenuous effort?

         insufficient rest or recovery time?

         prolonged effort?


  Individual capacity                 Does the job ~

         require unusual capability?

         endanger those with a health problem?

         endanger pregnant women?

         a team of similar height?

         call for special information?

         require particular skills or training?

         restrictions on movement or posture from unsuitable clothing and/or footwear? 


Load      

        What can the patient do for themselves, with or without encouragement?

Is the load ~

        heavy, bulky or unwieldy?

        difficult to grasp? 

        unstable or unpredictable?  

        potentially damaging, e.g. sharp or hot?


  Working Environment.             Are there ~

         restrictions preventing a good posture?

         uneven, slippery, cluttered floors?

         changes in floor and work surface levels?

         hot, cold or humid conditions?

         poor lighting conditions?

         equipment, attachments, personal belongings?


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

What about emergencies?

Emergency situations where people are being cared for, are foreseeable and Risk Assessments should be carried out for these:

The only emergencies where risks may have to be taken are known as the

FOUR REAL EMERGENCIES, these are situations where a person is:

Static load

  • Assess Risk       

  • Stable base        

  • Hold load close
