How To Measure Air Quality

Like all things, we can measure air quality scientifically. We can get a number that says just how gross the air in your facility is. Not only that, but we can figure out what particular type of problem your air has. There’s more to air quality than just saying it’s good or bad. The Troublemakers There are three commonly examined areas for air quality. We have different ways to detect and measure each of them, but these are typically available all in one tool or device. Particulate Matter There are tiny particles in the air, often harmful chemicals we don’t notice individually. Think of things like the exhaust from a car. That exhaust is made of billions of tiny particles of burned fuel and even metal shavings from the engine. These can have negative health effects. Particulates from cars could play a role in Alzheimers Disease. These can detect bacteria, viruses, and mold as well. Sensors for these are rated in their measuring sizes, 2.5 microns and below, 10 microns and below, etc. Your hair is about 40-70 microns thick, for comparison. Volatile Organic Compounds The rule of thumb is that a VOC is something you smell and notice. That’s not always the case, but it’s a good guiding post. These chemicals are highly reactive, dangerously so. Examples of these are things like cleaning chemicals, gasoline, and paint. They’re things you should try not to breathe in.

Indoor Air Quality

Heating your facility is important. It’s probably in the top ten most essential things to keep your workers and customers happy. It’s not the only thing. Warm air is useless if people can’t stand to breathe it in. Over time, air will get stale and become unpleasant to breathe. We need to not only heat the air, but clean it. What Is Stale Air? The air around you isn’t pure (unless you’re in a hyperbaric chamber, but that’s an entirely different can of worms). More accurately, the air we breathe is more like being in the ocean: it’s full of microscopic things floating around. If you’ve seen sea water, you usually see little things carried around in it. The same is true for air, but most of the things floating us are too small to see. Typically the air in a busy facility will be carrying: Skin Flakes and Hair Bacteria Viruses Mold Trace Chemicals (from cleaners, machinery, etc) Vaporized Sweat Chemicals from Oral Bacteria (Bad Breath) Particulates from Fabric, Food, and Product Offgassing Air becomes stale largely as a result of all these things becoming to abundant. The human body is incredibly perceptive to these things. We can smell, taste, and even feel that the air is not clean. There’s no way to just hide the problem either. Some scents can be fought off with aerosols, candles, and other products that alter the air. The only problem is that […]

Grading Your Steam

As with all things scientific and industrial, there are ways to quantify just how good steam is and where it can be used. We can think of these as three basic grades of steam: Utility, Culinary, and Pure. These essentially deal with how sterile the steam has to be, how much or how little water vapor it can carry, and what contaminants or additives it can be exposed to. Utility Steam There are numerous applications where the chemical make up of the steam isn’t a terribly big deal. Consider steam used for heating oil pipes. It doesn’t matter if the steam is wet or dry, if it contains any anti-corrosives, or if we put anti-freeze in it to prevent pipe bursts in the return lines. This is steam that’s never going to come into contact with humans, never touch food or clothes, or otherwise be an exposure risk. We put up a nice biohazard sign, some skulls and crossbones on the pipes, a sign that reads “if you drink, touch, or breath this, not only will you die, but it will be slow and painful,” and everything is pretty much set. The same can be said for steam used exclusively used to heat a building or dedicated to other purposes. In these environments, there’s not going to be human exposure, so it’s treated like any other chemical. In these instances, it’s helpful to use additives to extend the life of […]
