Stethoscopes Are More Germy Than Docs' Palms, Study Finds

By JoNel Aleccia

Health care workers’ hands are notorious for spreading germs in hospitals, but a new study suggests that the stethoscopes around their necks may be just as bad.

Researchers in Switzerland found that the diaphragms of stethoscopes — the part that a doctor presses against your chest — were more contaminated with the superbug MRSA than the palm of the hand.

Our Indoor Air Quality Program

Microfiber cloths to remove dustAllergies and asthma symptoms may be exacerbated by indoor particulates (a mixture of dander, dust mite feces, various forms of microbial life, and simple mineral dust).  These allergens can cause symptoms ranging from stuffy noses and watery, itchy eyes through major respiratory distress, and they are all easily controllable through proper building maintenance procedures.

Studies have shown a marked reduction in absenteeism when Indoor Air Quality procedures such as those used by CBN are observed.  Texas Air Filters states, “Measures to improve IAQ don't cost - they pay!”  The cost of proper cleaning is more than offset by the increased costs attributable to “sick time”.

CBN Building Maintenance uses the latest technological innovations to keep our clients breathing easy.  Let us introduce you to a healthier, safer, and more productive workplace.

Particle Counter to measure Indoor Air Quaity improvement
  Particle meterA hand-held airborne particle counter helps us measure Indoor Air Quality. The device draws in a volume of air, filters particles by size, and provides an accurate measure of air cleanliness. We measure our clients’ indoor air quality periodically, usually in conjunction with a daytime customer service visit; written reports, from initial readings onward, are available. Over a period of time, we generally observe significant Indoor Air Quality improvements using our dust control measures.

.

The industry is starting to notice – here’s an article by CBN’s Bob Croft, in September’s Cleaning and Maintenance Management magazine, on the details of our IAQ measuring program.

HEPA Vacuums
 

Backpack vacuums reach under furniture and into corners better.HEPA vacuums capture and retain 99.97% of the particles in the critical size range (appx 0.3 micron) which has been found to most cause allergic reactions and trigger asthma.  0.3 micron HEPA vacuums capture spores, pollen, airborne bacteria and dust mite feces.  Traditional paper bags only filter particles down to about ten microns; many janitorial firms still use old-technology dumpable cloth vacuum bags, which pump a visible cloud of even larger particles into the air.

Particles remain airborne up to eight hours after passing through the vacuum - waiting for you to remove them from the air by inhaling them yourself (ten microns is about the smallest particle visible to the eye; one micron is approximately the size of large cigarette smoke particles.  Many allergens are between 1 and 10 microns in diameter)

.

Particles in the one to ten micron range include airborne bacteria, some spores and pollen, and dust mite droppings - in essence, lots of allergens.  This size seems particularly dangerous to the lungs, based on studies of cancer, birth defects, etc.

Greenguard Environmental Institute
 

We use the Diversey “Healthy High Performance Cleaning” program, the only cleaning system currently certified under Greenguard Environmental Institute’s Product Emissions Standard for Children & Schools.

Our program combines certified cleaning chemicals, microfiber technology and advanced procedures to promote more healthful Indoor Air Quality.

Microfiber dust wipes - not feather dusters
  OstrichBesides allowing our poor ostrich to keep his tail feathers intact, our dust wipes trap dust - without dampening your furniture or leaving an oily chemical residue - and remove it from your building; much better than feather dusting the particles into the air for us all to breathe.
Microfiber damp wipes – not cotton towels
  Microfiber holds over seven times its weight in cleaning/sanitizing solution, allowing thorough cleaning and sanitizing of common touchpoints around the office. This helps to avoid cross-contamination, for instance from restrooms to lunch rooms.  Split microfibers retain the tiniest of particles, allowing us to remove them from your facility.  By comparison, old-fashioned cotton cloths (with much wider fibers) miss many particles.
Touchpoints – Avoid cross-contamination
Microfiber and Diversey's Alpha HP to sanitize touchpointsThe common places we all touch: flush handles, faucets, towel dispensers, light switches, doorknobs and jambs.  These are the touchpoints that you, along with everyone else in your office, touch every day.  We use Diversey’s Hydrogen Peroxide product, Alpha HP, as an effective sanitizer of touchpoints throughout your building.
Tile floors vacuumed – not swept
We vacuum hard floors for superior dust retentionBesides leaving debris in corners, against edges and under furniture - and in the irregular surfaces and grouting of ceramic floors - brooms and dust mops create air turbulence, lifting fine particles (near invisible to the naked eye) into the air to remain suspended for hours.  We use CRI Green Label Certified backpack-style vacuuums to "suck up and retain" dust rather than dash it about - also to more thoroughly clean corners, edges, and under furniture.
Microfiber damp mops - not string mops

Microfiber damp mops to clean better with less chemicalNumerous studies show that, compared to the traditional string wet mop, microfiber flat mops pick up more soil, use less solution (and less chemical in that solution), and avoid dirty water slopped onto furniture legs and baseboards. 

A study conducted by the University of California at Davis Medical Center (as reviewed by the US EPA) also demonstrates superior pathogen removal - bacterial culture shows a 30% removal using string mops, versus a 99% removal using microfiber.

Filtered floor burnishers
We use filtered floor burnishers to reduce airborne particulatesHave you ever noticed a coating of gritty gray dust on your furniture the morning after your janitor "polishes" your tile floors? Burnishing (ultra high-speed buffing - required for today's harder floor finishes) creates dust - a combination of ground-in dirt, powdered floor finish, and material wearing off the machine's pad.  Our filtered Laser X™ burnishers minimize this problem, and keep your air cleaner.
No aerosols
When spraying an aerosol, both propellant and chemical become airborne, which fouls the air and wastes the chemical. We use squirt bottles and pump sprayers; no propellant is involved, and more of the cleaning chemical hits the work surface. Better than in your air, don't you think?
No bleach or ammonia
Chlorinated bleach and ammonia are both noxious compounds in and of themselves.  Besides their individual characteristics of user unfriendliness and potential for damage to some surfaces (try dribbling bleach on your carpet), when accidentally combined, they produce chlorine gas - not something you want to breathe.
No scouring powder (AJAX, Comet, etc.)

Have you ever noticed the cloud of dust when you shake the stuff out of the can? 

Scouring powders are a combination of high pH detergents and finely ground pumice.  Many also contain bleach.  Inhaling this corrosive mixture is not at all helpful to your lungs.

Organic chemicals are widely used as ingredients in many cleaning and disinfecting products.  These products can release organic compounds while you are using them and, to some degree, when they are stored.   Eye, nose, and throat irritation, headaches, loss of coordination, nausea, and damage to liver, kidney, and central nervous system are among the noted health effects of VOC exposure.  Many organic compounds are known to cause cancer in animals; some are suspected of causing, or are known to cause, cancer in humans.

The ability of organic chemicals to cause adverse health effects varies greatly — from those that are highly toxic to those with no known health effect.  As with other pollutants, the extent and nature of the health effects will depend on many factors, including the level of exposure and length of time exposed.

The floor-care and office-cleaning products offered by Diversey are specifically formulated to be environmentally friendly and consumer health-positive.  They contain few or no harmful VOCs. This is one of the primary reasons we have chosen their product line.

Carpet protectant – an integral part of our carpet maintenance package

Included with our full-service janitorial program is application of a state-of-the-art carpet protectant to repel oil and grease and to keep dust and dirt from adhering to the carpet's surface.

Once sprayed, periodic spot cleaning becomes more effective.  The next full cleaning becomes more thorough.  Every night, as we vacuum, we remove more dry pollutants from your carpeting.  This extends the life of your carpeting, better maintains the appearance of your office, and keeps the air you breathe cleaner.

Disinfection and Sanitation
We use hospital-grade Virex II to disinfect all restroom and break room hard surfacesAdvanced sanitation service is one of the primary reasons for using a professional cleaning service (yes - there is a difference between simply cleaning and sanitizing).
Our staff is fully trained in both cleaning and sanitizing your restrooms and lunch rooms.  Microorganisms can survive for many hours on non-sanitized surfaces.  Serious food-borne illness is a very real consequence of preparing and eating food in a less than sanitary environment.
Disinfection with Diversey’s Virex™ II

In restrooms and break rooms, we use Diversey’s hospital-grade disinfectant, Virex II for the final step on all hard surfaces. Virex provides broad spectrum disinfection (pseudomonacidal, staphylocidal, salmonellacidal, fungicidal, virucidal).

Virex also assists in the elimination of biological-based odors.

Touchpoints – Avoid cross-contamination

Wiping touchpoints with microfiber cloth and Alpha HPThose common areas we all handle, such as flush handles, faucets, towel dispensers, light switches, doorknobs and jambs; these are the touchpoints that you – and everyone else in your office – touch every day

Alpha HP, Diversey’s new hydrogen peroxide based sanitizer, with a 60-second kill time, is highly effective against such pathogens as MRSA (staph), E. coli, TB, HIV, herpes, listeria, salmonella, cold and flu — and leaves no residue.  Applied with a moistened microfiber cloth, Alpha HP acts as an effective sanitizer of touchpoints throughout your building.

EPA and OSHA on Indoor Air Quality
Both EPA's and OSHA's indoor air quality sites discuss a wide range of IAQ concerns, including indoor air quality, airborne chemical pollutants, airborne diseases, sick building syndrome, asbestos, radon, and air quality dangers commonly emanating from HVAC ductwork and carpeting. These sites are geared to health professionals.

Would you believe that some common houseplants remove specific airborne pollutants common to our indoor environment? Research sponsored by NASA shows that philodendron, spider plants and dieffenbachia remove formaldehyde (found in new carpeting, insulation, particle board and furniture), English Ivy and chrysanthemums remove benzene (from oils, plastics, synthetic fibers) and so forth. Experiments also show that plants help remove airborne particulate matter (dust). Neat stuff (the information - not the dust).

Counterpoint to NASA article (We'll post any updates we find!)
  The idea of common plants solving IAQ problems is attractive. Most people like having plants in their homes and offices and in the hotels, stores, and public buildings they visit. However, important questions exist as to whether plants can actually affect indoor air sufficiently to warrant their use as air cleaners.
Carpet & Rug Institute (CRI)

The Carpet and Rug Institute (a national trade association of carpet manufacturers) has developed a "Green Label" testing program, focusing on indoor air quality, to aid both consumers and office designers in the selection of carpet, padding, and carpet adhesive. Of particular interest to us, their study also addresses the efficiency of various makes and designs of vacuum cleaners. Here they look at soil removal capability, carpet appearance retention and, most significantly, dust containment - not blowing the dust back into the room.
