Ergonomics: visual and physical

Ergonomics: visual and physical


To reduce physical strain and maximize ergonomic comfort and safety.


Overuse of the same muscles and ligaments while trying to adjust to static furniture or equipment over time can cause discomfort and strain the body, especially in occupational environments that require repetitive tasks. Under such conditions, the effects of even slight visual or physical discomfort are compounded, leading to decreased occupant comfort and focus.

Part 1
Visual Ergonomics

The following requirement is met:
All computer screens, including laptops, are adjustable in terms of height and distance from the user.

Part 2
Desk Height Flexibility

At 30% of workstations that are at seated height or similar work surfaces, users have the ability to alternate between sitting and standing through one of the following:
Adjustable height sit-stand desks.
Desk-top height adjustment stands.
Pairs of fixed-height desks of standing and seated heights (which need not be located adjacent to each other).

Part 3
Seat Flexibility

Occupant furnishings are adjustable in the following ways:
Workstation chair height adjustability is compliant with the HFES 100 standard or BIFMA G1 guidelines.
Workstation seat depth adjustability is compliant with the HFES 100 standard or BIFMA G1 guidelines.

Part 4
Standing Support

Workstations in which occupants are required to stand for extended periods of time include the following amenities:
At least 10 cm [4 in] of recessed toe space at the base of the workstation to allow decreased reaching requirements for occupants.
A foot rest to allow occupants to alternate resting feet.
Anti-fatigue mats or cushions.
