Employer Responsibilities
Because ozone can be an irritant, various regulatory agencies have estab-
lished limits to the amount of ozone to which employees may be exposed.
The workplace specifications are:
A person may not be exposed to an average concentration of greater
than 0.1 part per million (PPM) of ozone for a period of eight hours.
In addition, the employee should not be exposed to peak concentrations
of ozone greater than 0.3 PPM for longer than 15 minutes.
The employer is responsible for providing a work environment that meets
these standards.
Recommendations for Minimizing Ozone Exposure
Almost all ozone concerns arise from abnormal site or operating conditions.
The following conditions may generate an ozone complaint:
installation of multiple laser printers in a confined area
extremely low relative humidity
poor room ventilation
the exhaust port of the printer is directed towards the face of personnel
long, continuous printing combined with any of the above
Inspect your work environment for the operating conditions listed above if
you believe ozone emissions are a problem in your area.
Some people may be ultra-sensitive to ozone odor. If these situations are
encountered, it is advisable to position the printer away from the sensitive
user.
