Working in Comfort
30 English
The recommendation for room temperature is 19 to 23 degrees C (66
to 73 degrees F). If possible, adjust the temperature for whatever is
comfortable to you.
The workplace should be well ventilated (as with any indoor
environment).
Lighting
Lighting in your area should allow easy reading of documents and
keyboard legends.
Recommended levels are:
•
Not too bright. Values over 1000 lux (100 foot candles) are
considered to be too bright.
•
Recommended value is between 300 and 500 lux (30 to 50 foot
candles).
•
For work on the screen, 300 lux (30 foot candles) is enough for most
work.
•
When documents are to be read, 500 lux (50 foot candles) is
recommended.
If more light is needed for a particular task, use an individual lamp
("task lighting") rather than increasing the general lighting.
Incoming light should be shielded or diffused to prevent glare and
distracting reflection. In cases where strong sunlight is a problem,
curtains, adjustable shades, or display hoods are recommended.
If possible, try not to position the display in front of windows where
glare, high contrast, and reflections will interfere with your screen
presentations. Try to position the display so the screen is at a right
angle to the window.
