Work breaks Take periodic work breaks. Morning, lunch, and afternoon
breaks during the 7-hour workday meet most recommendations.
Take advantage of work breaks to move around and do other
activities.
Lighting Avoid direct lighting or sunlight on the screen, which causes
glare and reflections. Place lighting behind or to the side of your
work area, and distribute the lighting evenly on your work area.
Your server’s monitor screen has an antiglare treatment to
reduce glare. Adjust the brightness and contrast controls as
needed.
Noise Keep background noise at a minimum. Background noise above
65 dBA is tiring. Sound-absorbing materials (curtains, carpeting,
and acoustic tile) can help reduce background noise.
Temperature 20 to 23 degrees C (68 to 74 degrees F).
Humidity 30% to 70%.
Ventilation Provide adequate air ventilation to avoid fatigue and to operate
the equipment.
Space between set ups > 70 cm (28 in.) center to center, preferably > 152 cm (60 in.).
