What is ergonomics? - ANSWERSThe science of conforming the workplace and all its elements to the worker.
The goal of ergonomic is to fit the job to the worker.
What are the principles of ergonomics? - ANSWERS- consist of applying the scientific principles in order to
minimize the physical stress that is associated with the workplace
- involves special design and evaluation to make tasks, objects, and environments more compatible with
human abilities and limitations
- seeks to improve productivity and quality by reducing workplace stressors, reducing the risk of injuries and
illnesses, increasing efficiency
What type of disorder account for more than 40 per cent of all reported injuries? - ANSWERSAccording to
Ontario Workplace Safety and Insurance Board (WSIB) statistics, musculoskeletal disorders (MSD) account for
more than 40 % of all reported injuries .
What is the most costly medical condition in Canada? - ANSWERSMSDs ate the most costly medical condition
in Canada with direct and indirect costs estimated to be in the $22 billion range.
Who are at risk of developing repetitive strain injury, cumulative trauma disorder (CTD), repetitive motion
injuries (RMI), and soft tissue disorder? - ANSWERSWorkers in all industry sectors are at risk of developing
these disorders
, What is the most prevalent lost-time illness in almost every industry? - ANSWERSWork-related
musculoskeletal disorders are the most prevalent.
Musculoskeletal disorder (MSD) can be prevented - ANSWERSTrue
How can MSD be prevented - ANSWERSNeed to take appropriate steps to eliminate or reduce exposure to
work-related risk factors, which will minimize the risk of MSD in the workplace.
What are the benefits of ergonomics? - ANSWERS- improved health and safety for workers which results in
fewer workplace injuries/ health problems
- higher workplace morale
- improved quality (of finished product)
- improved productivity
- improved competitiveness
- decreased absenteeism and turnover
What are the 4 important disciplines of ergonomics? - ANSWERS- Anthropometry
- Biomechanics
- Physiology
- Psychology
What is anthropometry? - ANSWERSAnthropometry is the science of human measurement.
Anthropometry provides dimensional data regarding human body size.
What is biomechanics? - ANSWERSBiomechanics uses the principles of mechanical engineering and physics to
understand human movement. Biomechanics also assesses human muscle strength.
