HP to Researchers, 'Our Printers Are Safe' 89

Sidepocket_Pro sent us a link to this HP press release which reads, "Based on our own testing, HP knows that many variables can affect the outcome of tests for ultrafine particle emissions. Although HP is not aware of all of the specific methodologies used in the Queensland study, based on what we've seen in the report — as well as our own work in this area — we do not believe there is a link between printer emissions and any public health risk. Specifically, HP does not see an association between printer use by customers and negative health effects for volatile organic compounds, ozone or dust. While we recognize ultrafine, fine, and coarse particles are emitted from printing systems, these levels are consistently below recognized occupational exposure limits."

    One printer isn't going to cause harm, even if you are exposed for long times. However, the office I recently worked in, had about 7 printers for various purposes, and this was an office that used a particularly amount of paper, maybe they should carry out tests in more real conditions- it may not be an issue if you are ina sterile room with a printer, but lets face it, thats not gonna happen.

    All right, as one of Slashdot's numerous physician-readers, I'll chime in...

    As your intuition tells you, breathing stuff inside your lungs is, in general, quite bad. Your lung has numerous defense mechanisms that will swallow up inhaled gunk, known as macrophages, and to some degree destroy it. This system can be easily overwhelmed, and particles that are not able to be degraded by the macrophage essentially stay in the cell forever. This occurs after chronic and relatively large volume exposure, typically over many years, as common in coal miners.

    When you do your human dissections in medical school it is easy to tell the lungs of a smoker on gross examination, which have numerous black dots from macrophage-ingested carbon fragments. Even city-dwellers will have these particles. Breathing in coal particles gives something called Anthracosis http://en.wikipedia.org/wiki/Anthracosis [wikipedia.org] which can cause numerous problems later on if severe. Breathing in asbestos particles and silica dust also gives similar problems, and can even increase risk of some cancers (mesothelioma) although this is, relatively speaking, quite overblown (smoking is orders of magnitude worse for you than transient asbestos exposure.)

    Reading through HP's statement (I'm new here), I feel it is actually well worded and reasonable. Walking past your laser printer is fine. We would all be suffering if it were a health risk. There is not a large amount of aerosol created by normal printer operation under normal conditions, and nanoparticles fine enough to be lobbed long distances (across the entire office) are typically breathed in and out and not lodged in the lungs.

    In summary, avoid breathing in any huge ball of black powder. Don't take out the printer cartridge, shake, and sniff, three times per day. Stop smoking. Finally, always take sensationalist research with a grain of salt (not several grains of toner.)

    • One thing to consider is: are these expelled printer particles carcinogenic. Cigarette smoke and asbestos are, and much of their affect on the human body are related to that. Is printer in carcinogenic?

      Another thing to consider is quantity. People who get breathing problems from cigarette smoke, asbestos, coal, silica, and other substances like them tend to have very high exposure rates. They smoke 2 packs a day for 30 years. They manipulate asbestos/silica containing products in the workplace 8 hours a day

    What would you expect HP to say? "We believe there is a link between printer emissions and a public health risk?" I give HP enough credit to think that if they believed there was such a link, they would have done something about it... so by definition, since they haven't done anything about it they don't believe there's a problem.

      Here's my breakdown of their press release.

      Testing of ultrafine particles is a *very new scientific discipline. There are no indications that ultrafine particle (UFP) emissions from laser printing systems are associated with special health risks. Currently, the nature and chemical composition of such particles -- whether from a laser printer or from a toaster -- cannot be accurately characterized by analytical technology.
      There isn't a significant body of research and you can't prove that the particles are causing problems.

      However, many experts believe that many of the UFPs found in common household and office products are not discrete solid particles, but **may be condensation products or small droplets created during thermal processes.
      The experts we're quoting don't really have proof to back up their claims either.

      HP LaserJet printing systems, original HP print cartridges and papers are tested for dust release and possible material emissions and are compliant with all applicable international health and safety requirements. In addition to meeting or exceeding these guidelines, HP's design criteria for its laser printing systems incorporate guidelines from both the Blue Angel program in Germany and the Greenguard program in the United States.
      We're claiming our product is safe because it meets international guidelines, which *may or may not be based on any relevant scientific data.

      *we do not believe there is a link between printer emissions and any public health risk. Specifically, HP *does not see an association between printer use by customers and negative health effects for volatile organic compounds, ozone or dust.
      There's no data to prove a link and none of our studies have shown that there is (probably because we haven't been looking for one).

      **While we recognize ultrafine, fine, and coarse particles are emitted from printing systems, these levels are consistently below recognized occupational exposure limits.
      We admit that our products put out UFPs, but since they are at levels below the guidelines, we can pretend that it's safe, since there is nothing to contradict us.

      * These points are all related. Sometimes health guidelines are arbitrarily chosen. Other times, they're based on safety data from some semi-related guideline. HP tries to poke holes in the Queensland research by claiming that the field is new, yet attempts to fall back on 'the guidelines' in order to divest itself of any responsibility. There are no long term health studies, so HP is using the absence of evidence as evidence of absence.

      ** I'm not sure if they contradict themselves here or not, but they again try to fall back upon the guidelines as an authority.

They have a filtration system in the room where cartridges are stripped down to pieces, rebuilt, and then refilled. But the room is still filthy even with fancy filtration. In the next room over, they have about 20 laser printers for testing, but no special filtration.

      Black lung disease (coal miners) and white lung disease (ship yard workers, from asbestos particles) don't become problems until decades after exposure. It is possible that someone who worked a few months in a toner cartridge refilling operation 20 years ago will start to have problems in the next 5 to 30 years.

    Toner particles are made of a plastic-like material that is non-toxic and are generally 10-25 um in diameter. They put additives such as SiO2 onto the surface, these are nano-scale sized particles which are generally well attached to the toner.

    Claims this dust is as bad as cigarette smoking is a ridiculous statement, as toner particles are non toxic (tests have been done). Buildup in the lungs is a major issue however, as ultra-fine particles are not expelled from the lungs once inside -- this is a worry.

    I work for a large toner company, and we do tests on machines in enclosed areas with experimental toners. Areas we work in are monitored for dust particles, and we are well below safe limits. If our areas are safe, then an office environment certainly should be.

    Note the vast majority of problem machines are by HP -- particle emissions is not a problem in the industry, it just seems to be a problem with HP printers. HP is a manufacturer of "affordable" printers, perhaps they are not as well put together as more expensive machines. The media took a small issue and blew it out of proportion, much as it does with everything.

We also test our environment regularly for mould, which is something I am more concerned about, as you are.
