Since a large part of our janitorial service Phoenix program involves methodologies to measurably improve our clients' indoor air quality, I follow a number of news outlets focusing on health and air quality.
In a recent story by the Jacksonville, Florida CBS affiliate, I noticed that the National Highway Traffic Safety Administration is looking at a little noticed nationwide epidemic. "Since 2009, 14 people have died because they forgot to press the off button in their key-less car. Vehicles were left running in garages, slowly flooding homes with deadly carbon monoxide, a colorless odorless gas. Five of those deaths happened in Palm Beach County alone."
My first impression: one third of the deaths in one Florida (retirement) county alone. Forgetful seniors?
Secondly, though, my sense is that about two deaths per year, nationwide, doesn't quite reach "epidemic" proportions. I happen to have a key-less car, and also a keyed (is that the proper term?) pickup. Should I jump out of my (key-less) car without turning off the ignition, it beeps at me. My truck does not. So my unscientific hunch is that it would be less likely to find oneself poisoned by a running, key-less car than by the old-fashioned variety. I saw nothing in the article to compare poisoning rates of key-less to keyed cars, though even my sophomore high school science instructor stressed the importance of controls in any survey or experiment. Same with my college econ instructor.
But that wouldn't have made good TV news, or a good reason for a bit more NHTSA regulation.
Fortunately, our Phoenix commercial cleaning service does much not have to deal with carbon monoxide. We concentrate on improving client indoor air quality, and removing allergens and other bad things from the air our clients breathe. Thar means HEPA filtered vacuums, microfiber wipes and damp mops, and careful chemical selection - and we monitor client indoor air quality. Our results are consistent with the various studies on tweaking janitorial methodologies, and the achievable air quality results: a bit over a 50% reduction in daytime airborne particles, in the size range of most allergens. Finally, if we goof and leave the van running, it's outside. No poisoning here.
I also don't worry about my vehicles poisoning me at home. I don't have a garage.
