Ozone emission
Ozone gas is emitted by almost all laser printers and photocopiers. Because
ozone can be an irritant, various regulatory agencies have established limits
regarding the amount of ozone to which employees may be exposed.
The current OSHA permissible limit for ozone is 0.1 parts of ozone per
million parts of air (ppm). The Color LaserWriter 12/600 PS printer produces
quantities of ozone far below the current limit specified by OSHA.
To minimize ozone exposure, install the LaserWriter in a well-ventilated area.
If there are other laser printers or photocopy machines in the same area,
additional air circulation may be required. Do not place the LaserWriter in a
small, enclosed space that lacks adequate ventilation. Position the printer so
that the fan exhaust does not blow directly into anyone’s face.
