Lecture 7b: Sit/Stand Workstation Assessment Flashcards
risk factors for injury
- repetition
- force
- duration
- posture
other risk factors for injury
- noise
- temperature
- contact stress
principles of workstation design
- importance principle
- sequence of use principle
- function principle
- frequency of use principle
importance principle
those components which are most essential to safe and efficient operation should be most accessible
sequence of use principle
components which have to be operated in a sequential fashion should be located close to each other and their layout should relate logically to the sequence
function principle
provides for the grouping of components according to their function
frequency of use principle
those components which are used most frequently should be in the most accessible positions
seat design should consider
- function
- anthropometrics
- comfort
lumbar support and backrest inclination …
decreases disc pressure
acceptable arm abduction and flexion angles:
abduction: 15-20 degrees
flexion: 25 degrees
desk height
5-10 cm below elbow height
lower for forceful work
higher for precision work
seated work assessment tools
1) Rapid Office Strain Assessment
2) Rapid Entire Body Assessment
what is the ROSA used for?
quantify exposure to risk factors in an office environment
correlation between discomfort and increased ROSA score
ROSA scoring
score 1-4: further assessment not required
score 5-10: further assessment required
what is the REBA used for?
entire body activities
