Office Ergonomics
Posture
Vision - if the workstation does not encourage good vision, then the worker may adapt poor posture and positions to see their workload therefore experience pain and therefore be less productive.
-
-
Can sit or stand but, individual, attitude, workplace design, previous experience all contributes to ergonomics.
Workstation set up
Office Chairs
Should swivel, height adjustable, 5 point of base, back rest to stabilise trunk, back rest inclination.
Keyboard

Noise
Performance - reduce productivity, decreased alertness, difficulty with communication
Health - increase stress, headaches, increase heart rate and respiration rate, noise induced hearing loss

Workstation location
Home, seated, standing hot desk
-
awareness of noise, seats, airflow, temperature, ambient light, computer display quality, glare

Definition of ergonomics
Optimise relationship between people and their work to ensure a happier workplace, less injuries and that the staff member has increased productivity, less fatigue, higher work satisfaction, less errors..
Principal 1: Capacity vs Demand - injury occurs when a persons capacity exceeds the demand of the task = unsafe workstation.
Principal 2: Human machine environment system, position and access to display and keyboard, taking on the human's attention span and learning.
Human, machine/task/environmental factors assist in injury prevention and recovery
