“Greetings. Thank you for inviting me. If you have difficulty with my accent, I can always start in Hindi. But my parents could not understand my Hindi. My Puerto Rican wife does not understand my Spanish. My son and my students do not understand my English. With all this confusion, let us continue in English. Thanks”

ERGONOMICSFirst Introduced into the Scientific Literature By a Polish educator/biologist/scientist WojciechJastrzębowski in 1840
What is ERGONOMICS?
Ergonomics = • Ergon (Work) + • Nomos (Norms or laws)
My Mentors • Dr T P Ojha, Indian Institute of Tech • Dr C W Suggs, N C State U, Bio & Ag Eng • Mr Stanley Lippert, 5th Pres of HFS • Dr Ervin Tichauer, NYU Inst of Rehab Med • Dr John Grimaldi, NYU Center for Safety • EntienneGrandjean, Switzerland
My Approach • Holistic, • Systems, • Inclusive, • Commonsense
Time and motion study • A businessefficiency technique combining • the Time Study work of Frederick Winslow Taylor with • the Motion Study work of Frank and LillianGilbreth • It is a major part of scientific management (Taylorism).
T&M Studies • Time study standard times, • Motion study work methods. • Consider SHE implication of excessive productivity
Ergonomics is Common Sense • which our grand mothers tried to inculcate in us- “excesses are bad.”
Repetitive exposures to excessive stresses without proper training or rest may result in • lifting challenges, • hyper- and hypo- thermia, • hearing loss, • cumulative traumas, and • carpal tunnel syndromes.
Most of the diseases are • Cumulative traumas or mini-injuries • Symptoms take longer to appear • One cell deforms or dies at a time
Ergonomics improves productivity, safety and health, and the quality of life. It depends upon one’s psychosocial and physical environments • It is essential that internal bodily environment be in harmony with the external environment.
Disharmony Disharmony between internal bodily stresses and external stresses Injuries, Illnesses, Environmental challenges
Communication Challenges • Written • Linguistic • Verbal- accent • Non Verbal: • Speaker’s appearance & attitude • Listener’s attitude, biases, needs
Ergonomics balances internal bodily environment with external physical & psychosocial environment
This balance improves safety, health, and productivity in a friendly environment.
Psycho-social & Physical Environments are functions of one’s • Culture & • Genetic make-up
Adaptability: • has posed significant challenges to • Safety, • Health, and • Environment
