ERGONOMICS
What is Ergonomics?
- a field of study dealing with the comfort and safety of the human body by adjusting tools, work stations and work processes to fit the worker.
Human-Machine Relationship
-how humans can be best integrated with machines to maximize safety & task performance.
Human-Machine Relationship Office Ergonomics
-the branch of ergonomics dealing with the office environment.
-the aim of ergonomics is to minimize the mismatch that occurs between the person and the job or match the capabilities of humans and the requirements of the job they are expected to perform.
Human-Machine Relationship Office Ergonomics Alexander Technique
- It guides you to do all your normal physical activities like sitting, standing, etc without tensing your body. It is NOT AN EXERCISE or a TREATMENT, but IT EDUCATES you to improve the quality of your life.
Human-Machine Relationship Office Ergonomics Alexander Technique Psychosocial & Organizational Aspect of Work
-What is a psychosocial factor?
Psychosocial factors are those factors that affect a person psychologically or socially.
What are psychosocial risk factors?
Psychosocial risk factors are things that may affect workers' psychological response to their work and workplace conditions (including working relationships with supervisors and colleagues).
Human-Machine Relationship Office Ergonomics Alexander Technique Psychosocial & Organizational Aspect of Work Ergonomic Injuries
-Ergonomic injuries, often called musculoskeletal disorders, affect the
muscles, tendons, nerves, ligaments, joints and/or blood vessels.
Ergonomic injuries are typically caused by or made worse with repeated
exertions, awkward positions and / or forceful movements.
WORKPLACE INJURY PRECAUTIONS
Safety Training Understanding Job Risks Following Safety Precautions Preventing Common Injuries
Ergonomic Factors to Consider
Does it suit your body size? Does it also suit all other users? Can you see and hear all you need to easily? Do you understand all information presented? Do errors occur frequently, and is it easy to recover
from them? Des the equipment or system cause discomfort if you
use it for any length of time?
Is it convenient to use? Is it easy to learn to use? Is it compatible with other systems in use? Could any of these aspects be improved? Do other users have similar reactions?
Identifying Problems
Causes of accident & near misses may be attributable to people being: Unable to see important displays; Unable to reach controls; Unable to work in a comfortable position; Overloaded with to much information at one time; Inattentive because there is too little to do or too little
variety Medical and absences records may also reveal problems
with particular jobs or tasks
Solutions
Risks can be reduced by changes to designs of workstations, tools and work organization
Simple solutions are often better Involve and consult the workforce Monitor remedial actions to ensure
effectiveness

Office Ergonomics
the branch of ergonomics dealing with the office
environment.It aims to minimize the
mismatch that occurs between the person and the job or match the capabilities of
humans and the requirements of the job they are expected to
perform.
Sources of injury in the office
•Falls
•Repetitive movements.
• The way you sit or stand (posture).
• Bending over, lifting heavy objects, or using pressure or force.
• Working with vibrating tools.
• The average person working at a keyboard can perform 50,000 to 200,000 keystrokes a day
• Overexertion, falls & RMI are the most common cause of workplace injury
• An average of 125,000 back injuries due to improper lifting each year.
• Muscles overuse results in tiny tears in the muscles and scarring; these contribute to inflammation and muscle stiffness
Facts About Ergonomics
What causes Nerve Compression or Entrapment?
1) Repeated motions
2) Tight muscles
3) Inflammation of surrounding tissues
4) Misalignment of the nerve
What are 4 Common Nerve injuries?
I. Thoracic Outlet Syndrome: brachial plexus compression d/t muscle tightness side of neck from poor head position or slumped posture.
S/Sx: numbness/tingling in hand, made worse w/overhead activities or cradling phone b/w ear and shoulder
Nerve injuries
II. Radial tunnel syndrome: compressed radial nerve @ outside of elbow d/t repetitive wrist & finger extension or turning of forearm
S/Sx: Sensations from elbow to base of thumb w/ wrist weakness a common sx
Nerve injuries
III. Cubital tunnel syndrome: ulnar nerve compression inside of the elbow d/t repetitive bending of elbow or resting your elbow on a hard surface
S/Sx: numbness or tingling and inside of arm w/ tingling to ring & little fingers
Nerve injuries
IV. Carpal tunnel syndrome: compression of median nerve at level of carpal tunnel
Where is carpal tunnel? Formed @ wrist by ligament over the carpal bones in handS/Sx: numbness or tingling in thumb, index, or middle finger & ½ of ring finger

Ergonomics Standards
New ISO standard on the basic principles of ergonomics
ISO 26800:2011, Ergonomics – General approach, principles
and concepts“A substantial number of ergonomics standards have been developed to cover specific issues and different application domains, but ISO 26800:2011, Ergonomics – General approach, principles and concepts, will serve as an umbrella reference for all such standards and provide an integrated framework bringing together the basic principles and concepts of ergonomics in one document, and thus providing a high-level view of the way in which ergonomics is applied“
Georg Krämer, Chair of ISO Technical Committee
ISO 26800:2011, Ergonomics – General approach, principles
and concepts
ISO 26800 describes these fundamental principles in order to improve safety,
performance and usability (effectiveness, efficiency and satisfaction), while
safeguarding and enhancing human health and well-being, and improving accessibility,
e.g. for elderly persons and persons with disabilities.
ISO 26800:2011, Ergonomics – General approach, principles
and concepts
The intended users of this standard are designers, ergonomists and project
managers, as well as managers, workers, consumers and procurers. Its specific goal is to facilitate task performance, safeguard and enhance the safety, health and well-being of
the worker, or the user/operator of products/equipment, by optimizing tasks,
equipment, services, and the environment.
ISO 26800:2011, Ergonomics – General approach, principles
and concepts
This standard deals with • the ergonomic approach,
• the principles of ergonomics• the concepts of ergonomics, and
• the ergonomics-oriented design process and conformity.
ISO 26800:2011, Ergonomics – General approach, principles
and concepts
ISO 26800:2011, Ergonomics – General approach, principles and concepts, was developed by ISO technical committee
ISO/TC 159, Ergonomics, subcommittee SC 1
Five Changing Trends in Managing Workplace
Ergonomics1. Getting Proactive
Fifteen to 30 years ago:The focus of most ergonomics
programs was on MSD injuries.
REACTIVE APPROACH
Today, the leading companies are
PROACTIVE.
Five Changing Trends in Managing Workplace
Ergonomics2. Integrating the Process
Companies with effective ergonomics programs tend to manage ergonomics as a process that is aligned with, or integrated into, existing improvement processes.
These improvement processes may include :
Lean ManufacturingSix SigmaContinuous ImprovementSafety Management Systems.

Ergonomics
3. Engaging Others and Shifting Ownership
Two critical elements of safety and environmental management systems:
Employee Involvement
•They can adjust their own
workstations
•Become members of an
ergonomics or safety team
involved in assessing and
improving conditions
•Participate in a Kaizen event.
Management LeadershipTraditionally, safety professionals have driven ergonomic improvements in an effort to reduce injuries, but all along they have been the wrong people to do this.
Ergonomics is an Engineering Discipline.
The responsibility for designing workstations, processes, tools, and workflow resides with engineers (process, industrial, and facilities engineers, as well as space planners and product designers).
Five Changing Trends in Managing Workplace
Ergonomics4. Moving Upstream
•Consistently addressing ergonomics in the design phase of new processes, equipment, layouts, and products is a common practice of advanced organizations.
•The greatest value of good upstream design is the reduced cost of making changes.
•Progressive leading companies have integrated design criteria in their phase gate review process and hold projects and people accountable for designing workplaces and tasks with low exposure to MSD risk factors.
Five Changing Trends in Managing Workplace
Ergonomics5. Addressing the Office
1980’s - Office Ergonomics were in-person evaluations by EHS staff, chair fitting rooms, lots of custom solutions for each person, and classroom training.
Thirty years later, we are a bit smarter:•There is less dependency on in-person assessments.•Workstations and chairs have a full range of adjustability.•Office workstation design is based on computer use.•Employee training focuses on enabling people to assess and adjust their own workstations.
•The biggest trend in managing office ergonomics has been the movement toward Employee-driven Assessments and Workplace Changes.
•By providing online training and self-assessments, employers are enabling and empowering individuals to take the first steps in adjusting their workstations to fit them.
COMMON ISSUES AND BARRIERS:
Two common challenges with managingergonomics that companies at all levels ofprogram maturity have experienced:
Funding for training and engineering solutions.
Failure to use or meet established ergonomic design standards.
10 Principles of Ergonomics
• Work in Neutral Postures• Reduce Excessive Force• Keep Everything in Easy Reach• Work at Proper Heights• Reduce Excessive Motions• Minimize Fatigue and Static Load• Minimize Pressure Points• Provide Clearance• Move, Exercise, and Stretch• Maintain a Comfortable Environment
Other Fields of Ergonomics
• Cognitive Ergonomics• Participative Ergonomics• Behavioral Based Ergonomics• Ergonomics of Innovation• The ergonomics of dishonesty
Cognitive Ergonomics
studies cognition in work settings, in order to optimize human well-being and system performance
focuses on the fit between human cognitive abilities and limitations and the machine, task, environment
Cognitive ergonomics aim to enhance performance of cognitive tasks by:user-centered design of human-
machine interaction and human-computer interaction
design of information technology systems that support cognitive tasks
development of training programs work redesign to manage cognitive
workload and increase human reliability
Participative Ergonomics
Resources and Support:• time for the program to develop• time to develop and implement solutions• financial resources to make meaningful
changes in the workplace• management support for the individuals on
the ergonomics team.
• Behavioral Based Ergonomics• Ergonomics of InnovationHow to make it successful?• think about how to build upon a
successful blend of existing ideas rather than develop the newest and most radical ones.
• set a public, inspiring, and difficult goal, and then break it down into manageable chunks.
• improve the chances that innovative ideas will spread by encouraging our organizations to identify possible ways to help others understand and apply new products, systems, and procedures.
• The Ergonomics of Dishonesty
Participatory Ergonomics
A Path to Sustainable Ergonomics
Participatory Ergonomics?
Two extremes to foster ergonomics: Top-Down “Push” Bottom-Up “Pull”
Top-Down “Push”
Bottom-Up “Pull”
In practice, it’s push-and-pull that leads to success and sustainability
PUSH PULL
The role of the Ergonomist: Leadership & participation Gaining respect & approval from
leadership Gaining respect & approval from
associates & stakeholders Providing ergonomics expertise Developing repeatable,
sustainable processes Pushing & pulling as needed

Ergonomics and Human Factors
New Trends in Sports Product Design
Sugru
a thermoset silicone rubber which is great for forming grips, handles, mounts and seals, and can be shaped by hand with great effect.
The material has three main benefits over other comparable products:
It bonds very well to most materials (including itself)
The material can be finished to a high standard if care is taken
It has good thermal and strength properties
For ergonomists, sugru has the potential to form a new part of the methods and techniques used to inform design decisions, especially for co-design purposes. Thus, providing it is used appropriately, sugru has the potential to greatly improve the user experience of many products.
Battery Powered ‘Hot Pants’
developed for the British cycling team. Loughborough University, Adidas and Team GB worked on the development of heated trousers…
It’ll slow the decline in muscle temperature between warm-up and the start of an event which, as a result, increased cyclist event performance i.e. sprint power.
Morrant Cricket Pads
Lightweight (1lb 2oz), moulded, and with high density foam, developed by Morrant International that only include two straps on the lower leg.
It frees up the knee joint for running and lunging movements, and reduces the weight of the personal protective equipment being worn/carried by the batsman whilst still offering the same level of protection.
