Photocopying machine

In displacement ventilation systems air is supplied to the room at low velocity, with a volume flow rate near the floor, and is extracted near the ceiling. The temperature of the supplied air is slightly lower than that of the room. Air is heated by the objects in the room, e.g., computer terminals and photocopying machines, and it rises due to buoyancy. 

Control photocopying machines where access to customer data can be obtained. Destroy data by shredding and secure disposal. 

VOCs are emitted indoors by building materials (e.g., paints, pressed wood products, adhesives, etc.), equipment (photocopying machines, printers, etc.), cleaning products, stored fuels and automotive products, hobby supplies, and combustion activities (cooking, unvented space heating, tobacco smoking, indoor vehicle use). 

Although only 10-50 ppb ozone is present in the atmosphere at ground level, higher concentrations occur near photocopying machines this is sufficient to degrade polymers, especially those with unsaturation in the polymer chain, e.g., elastomers.

Metalloid that exists as two allotropes, one glasslike and the other metallike photoconducting properties useful in photocopy machines included in the diet, it has health benefits. 

There are some additional sources of 03 indoors. These include dry-process photocopying machines, laser printers, and electrostatic precipitators (e.g., Leovic et al., 1996 Wolkoff, 1999). Indeed, it is not unusual to detect O, by its odor during operation of some copy machines and laser printers.
