Probably everyone who deals with printing devices repair of toner cartridge refilling take place begins to wonder: 'is toner hazardous for me personally?'
Laser printers, copiers and toner itself cannot be positively defined as very harmful or absolutely secured. Like many home appliances, they have their maintenance rules to know and observe. Not taking precautions may have a regrettable effect.
As far as copiers are concerned, you should consider this: image drum assembly heats up to 200 degrees Celsius and the coolers blow out gaseous waste products, dust and even toner (in the event that the device has poor technical condition or the cartridge is faulty).
Such temperature combined with water vapor derived from paper releases volatile organic reagents, which are contained in toner and paper. May be those reagents that are blown out of printer or copier. A wide variety of them, like benzene or styrole, are thought to be to be very hazardous and considered cancer-causing. Many individuals if often abused by tabloids help to make it up another sensational submit. However, actual figures or comparison strength within the reagent by no means mentioned. For instance, from those articles you'll don't know that a printer working continuously the hour exhausts about 10 time less benzene than a single smoked cigarette.
Ozone emission, once a hot topic, doe not appear along at the agenda much more. The reason is strict modern standards for printing equipments - emission level of today's printers is low enough to call it safe.
As for the chemical associated with some associated with toner, it's worth mentioning that most 'hazardous' is Carbon Black class black toner, which is used by numerous monochrome printing equipment. This kind of toner contains iron oxide and carbon as color agents, which at sufficient concentration have adverse affect human future health.
Color toners are associated with heady metals as these types of made of organic polymers - the plastic, staying brief. Getting rid of toners acquainted with occasionally contain tin as part of high toxic organic compounding. It was once added to create to protect ships bottom from seaweed and buttocks. The substance got to human body through 'fish - seafood - human' or 'fish - fish-meal - livestock feeding - meat - human' food chains, hence the influence.
When contacted with skin, eyes, mouth, etc., toner may cause allergic reactions, depending on actual living thing. The reasons behind this phenomenon are not thoroughly checked out. Explicit allergic properties of toner have not been discovered (expect for your fine granulation) and, what seems most likely, allergic reaction can be compared to it of flour, home dust or blossom dust.
Another case is when a person provides continuously stay in toner (or, say, cement) polluted premises, where skin and eyes are regularly exposed for the powder. Professionals have proved that such environment may cause long-lasting cough, skin crackles and inflammation and asthma.
Summing it up, this is what you need to know about printers and printer toner safety:
Neither printing equipment, nor toner by itself is something you can call very harmful or absolutely trustworthy. Like other home appliances and chemistry, they require observing storage, usage and maintenance rules.
The quantity potentially health affecting chemical reagents emitted at printing equipment work, for most part, meets the emission level requirement and doesn't exceed emission level of same reagents from other sources (not related with printing machinery).
Office printing equipment requires being timely and periodically maintained at the service, for instance the manufacturer suggests.
Laser printer and toner are less harmful during printing process than a cigarette smoke or the salt over shelf inside your kitchen.
Most (potentially) hazardous include the ultra-fine particles of the toner. However, same holds true not only for toner, however for other fine powder particles of similar size and weight. Unlike cement, toner is refilled in closed and often small premises, so everyday working environment must secure toner fine particles from finding its way to workers noses, mouths and lungs.
Don't be paranoid and go to extremes - use needs to instead.
