Printer Toner: Is it Hazardous or Not?
Laser printers, copiers and toner itself cannot be positively defined as very harmful or absolutely safe. Like many home appliances, have got their maintenance rules comprehend and observe. Not taking precautions may have a regrettable effect.
As far as copiers are concerned, you should consider this: image drum assembly heats very much 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, will be contained in toner and paper. It is those reagents that are blown out of printer or copier. Any one them, like benzene or styrole, are viewed to be very hazardous and classified as cancer-causing. Are not aware if often abused by tabloids additional medications . up another sensational report. However, actual figures or comparison strength for the reagent should mentioned. For instance, from those articles you'll can never predict that typical printer working continuously for an hour exhausts about 10 time less benzene than one smoked e cigarette.
Ozone emission, once a hot topic, doe not appear while on the agenda a lot 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 your chemical aspect of some regarding toner, it's worth mentioning that most 'hazardous' is Carbon Black class black toner, which is used by numerous monochrome printers. This sort of of toner contains iron oxide and carbon as color agents, which at sufficient concentration have adverse effect on human healthy.
Color toners are involving heady metals as effectively made of organic polymers - the plastic, to become brief. It will likely be toners that would occasionally contain tin for a part of high toxic organic compounding. This substance was once added to create to protect ships bottom from seaweed and shells. The substance have got to human body through 'fish - seafood - human' or 'fish - fish-meal - livestock feeding - meat - human' food chains, hence the reputation.
When contacted with skin, eyes, mouth, etc., toner may cause allergic reactions, depending on actual affected individual. The reasons behind this phenomenon are yet regarding thoroughly searched. Explicit allergic properties of toner have not been discovered (expect for the fine granulation) and, allocated to weight loss most likely, allergic reaction can be compared for that of flour, home dust or blossom dust.
Another case is when a person provides continuously keep in toner (or, say, cement) polluted premises, where skin and eyes are regularly exposed towards powder. Something which proved that such environment may cause long-lasting cough, skin crackles and inflammation and bronchial asthma.
Summing it up, this is what you keep asking about printers and printer toner safety:
Neither printing equipment, nor toner by itself is something you can call very harmful or absolutely stable. Like other home appliances and chemistry, they require observing storage, usage and maintenance strategies.
The involving 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 manufacturer tells.
Laser printer and toner are less harmful during printing process than a cigarette smoke or the salt over the shelf in your kitchen.
Most (potentially) hazardous always be the ultra-fine particles of the toner. However, same is true not for toner, but 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 mental instead.
