Systematically integrating physical and
psychosocial risk assessments early in
any ‘design process’ to eliminate or
minimise risks throughout the entire life of
the plant or structure being designed.
and
Safe Design for MSDs means
![Page 3: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/3.jpg)
Systematically integrating physical andpsychosocial risk assessment early in the ‘design process’ to eliminate or minimise the risks throughout the life of the plant orstructure being designed.
And
Systematically integrating physical and psychosocial risk assessment into the ‘processes’ for the design of the organisation and the work and systems to eliminate or minimise the risks.

Poor plant and equipment design
Contributes to traumatic deaths and injuries
37% definitely or probably
14% suggestive
of these 90% involve use of machinery and fixed
plant (Driscoll et al, 2008)
Known risk factors for work-related MSDs

Extreme and or limited ROM
Repetitive or sustained force
High or sudden force
Repetitive movement
Sustained and/or awkward posture
Exposure to vibration
![Page 8: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/8.jpg)
Poor working environments and inherent
and risks impact safety
Extreme hot/cold
ambient
temperatures
known MSD risk
10- 800% greater
risk if working in
heat (Pisaniello et al
2018)

Contribution to frustration, stress,
fatigue and errors commonly
ignored or inadequately
considered in MSDs risk
assessments
Human computer/machine interface designs shape physical, cognitive
and emotional responses
![Page 10: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/10.jpg)
Psychosocial
hazards arising
from design and
management of
work and
organisational
context
Physically, emotionally and cognitively
demanding work
Long working hours/shift work
Time pressure
Poor job control
Responsibly control imbalance
Poor informational, instrumental and
emotional support
Challenging physical working environment
Working alone or isolated work
Workplace conflict
Effort reward imbalance etc
![Page 11: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/11.jpg)
Poor ‘plant and work design’ erodes
coping capacity, safety and performance
11
➢ Requires more physical, mental and emotional effort
➢ Increased physical and mental fatigue and stress
➢ body part discomfort and fatigue
➢ reduced cognitive capacity
➢ reduced ‘stress tolerance’
➢ Increased slips, lapses, mistakes, deliberate violations and ‘poor behaviours
Under stress poorer performance is almost inevitable

✓ Designs ‘fit diverse users’ not ask ‘users to fit’ the design
✓ Good designs accommodate operational needs
✓ Understand how people really work and accommodate safe or restrict
unsafe ‘work arounds’
✓ Ensures all ‘hidden designers’ of work understand the implications of
their decisions
✓ WHS risks considered at contemplation, throughout design process
and checked at final review
✓ Uses tools like PErforM
✓ Uses optioneering, protype testing, design review workshops, piloting
of new plant and work systems to verify and validate design solutions
Getting to ‘good’ needs participatory
design approaches
![Page 13: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/13.jpg)
✓ Are architects, builders and interior designers adequately considering
the manual tasks that will or may be performed throughout the whole
lifecycle of the building (construction, use, maintenance and
refurbishment)?
✓ Do you (as the purchaser) know what your workers and other users
(eg patients, visitors) WHS risks might be?
✓ Are you actively communicating these to the designers and builders?
✓ Are you checking these risks have been adequately considered and
controlled in new buildings and fit outs before you accept sign off?
✓ Are you doing a thorough post-occupancy review to identify and then
fix issues?
Buy safe buildings MSD checklist
![Page 14: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/14.jpg)
Buy Safe plant and materials
Design and manufacturing standards vary in
completeness and relevance especially with new
technology
While there are WHS obligations on designers,
manufacturers and suppliers of plant and lifting
equipment these are not always met
Mistakes are costly - buyer beware

Buy Safe MSD checklist
✓ Are the right people (right qualifications and expertise) authorising your purchases? Do they understand the ‘work as real’?
✓ Have your workers had genuine input?
✓ Has a risk assessment been done before purchase to identify unintended use or misuse risks and are these adequately controlled?
✓ Have you checked is it ‘fit for purpose’, will it do the intended job?
✓ Will it ‘fit right’, is it comfortable and safe to use now and in the future?
✓ Will it represent long term value for money? 15
![Page 16: Workplaces and design stream: MSD prevention thru safe design · Dr Peta Miller. Systematically integrating physical and psychosocial risk assessments early in any ‘design process’](https://reader034.fdocuments.us/reader034/viewer/2022050505/5f973a5038e2cf42a254a3b6/html5/thumbnails/16.jpg)
Buy Safe MSD checklist continued
✓ Will you inspect and pilot test before you place the order?
✓ Is it easy to learn to safely use?
✓ Does it ‘tell’ the user if it is unsafe or there are unsafe operating conditions?
✓ Can it be adequately, easily and affordably maintained?
✓ Can it be safely and quickly transported to where it is needed?
✓ Can it be conveniently and safely stored when not in use?

Buy Safe PPE MSD checklist
Is the PPE at your site a hazard or control? PPE purchased by you or by your workers and others.
✓ Does PPE ‘fit right’ - is it comfortable and safe to use by your staff now and in the future? (anthropometrics – suits the full range of worker body dimensions and strength etc.)?
▪ Uncomfortable PPE wont be used and can create safety risks
✓ Do staff use PPE and if not why not?
▪ Forcing workers to wear PPE when risks are not present can be counterproductive. If they are not using them see if this is justified.
✓ Are back braces being used as a PPE? If they are this should trigger a new risk assessment.
▪ Back braces are of no or limited benefit in reducing pain and increasing RTW (van Duijvenbode et al 2008) except in very limited circumstances

Use it safe It is not what people say they do most of the time – it is what
they actually do when under time pressure.
Check if and how plant and lifting devices are really used

Operating plant safely MSD checklist
✓ Are operating procedures and instructions clear and up
to date?
✓ Is the paperwork a help or a hazard?
✓ Do people know how to safely and efficiency use plant
including manual handling devices?
✓ Does the site design and working conditions allow the
equipment including lifting devices to be used safety?
✓ Do people check if the plant it safe or if operating
conditions have changed? (new risks and controls still appropriate)

Safe operating conditions checklist
✓ If hazardous manual
handling is still part of
the job, are the best
lifting techniques
known and used?
✓ Is there good
communication and
coordination between
those working and
lifting together?

Safe operating conditions checklist
✓ Does your organisational culture actively support safe manual handling practices?
✓ Check again does the work design (especially time pressures) allow plant and lifting devices to be used safely?
✓ Are reasonable adjustments made for workers with special needs?

Does your risk management processes include
safe design, buy safe, use safe and keep it safe
approaches?
✓ Does your organisational change management policies
specify checking and controlling for new WHS risks?
✓ Are the key MSD risks including the biomechanical,
psychosocial and environment hazards/risks included in
your risk register?
✓ Are these adequately controlled?
✓ Are the residual risks known? Are they adequately
controlled?

Key Messages - MSD prevention
Design in safety – ensure those who design the work and working environments design out MSD and psychosocial risks
Buy safe – ensure your plant and equipment procurement are appropriate and don’t introduce risks
Use it safely - ensure your work design and system supports safe use of plant and equipment
Keep it safe - monitor buildings, plant and workspaces –ensure your housekeeping and maintenance is appropriate
Keep learning from what is going right as well as what when wrong
