This effect does not last long, but the length of time you need to wait before zeroing varies, so the approach leaves plenty of room for error.įor typical dirt and grime, I recommend wiping down your gas detector with a soap-and-water solution (eight to 10 parts water to one part dish soap, like Dawn®). This cleans the monitor with less risk of damaging the sensors or putting you at risk of a malfunction. However, the soap-and-water approach only cleans the monitor of everyday buildup it does not necessarily kill bacteria or viruses that may exist on the surface. To disinfect your monitor after cleaning, wipe it down with a bleach-and-water solution of approximately 50 parts water to one part bleach, as recommended by the CDC. The CDC advises using 5 tablespoons (one-third of a cup) of bleach per gallon of water, or 4 teaspoons of bleach per quart of water. No matter which method you use, be sure to dock the monitor or bump test it before use, to be sure it's working properly.įor more information, visit call (412) 788-4353 or email from CDC: Cleaning vs. disinfecting surfacesĬleaning refers to the removal of dirt and impurities, including germs, from surfaces. Cleaning alone does not kill germs, but it decreases their number and therefore any risk of spreading infection.ĭisinfecting works by using chemicals to kill germs on surfaces. This process does not necessarily clean dirty surfaces or remove germs. But killing germs remaining on a surface after cleaning further reduces any risk of spreading infection. If surfaces are dirty, they should be cleaned using a detergent or soap and water prior to disinfection.įor disinfection, diluted household bleach solutions, alcohol solutions with at least 70-percent alcohol and most common EPA-registered household disinfectants should be effective. Diluted household bleach solutions can be used if appropriate for the surface. Follow the manufacturer's instructions for application and proper ventilation. Check to ensure the product is not past its expiration date. Never mix household bleach with ammonia or any other cleanser. To view CDC's complete Environmental Cleaning and Disinfection Recommendations, visit Instruments GX-3R Four Gas Monitor - the worlds smallest gas monitorĬlick here to learn more from RKI Instruments website Unexpired household bleach will be effective when properly diluted. OSHA defines the breathing zone as a ten inch radius around the worker’s nose and mouth, and requires that worker exposure monitoring air samples be collected in the breathing zone. Air sampling filters may be attached to the collar or lapel. Traditionally this means only a single gas monitor would be small enough for a worker to practically wear a gas monitor ‘In the breathing zone’. Now there is a 4 gas monitor smaller than many single gas monitors. The GX-3R is the worlds smallest 4 gas monitor weighing only 3.52 ounces and can comfortably be clipped within a worker’s breathing zone (2.2” W x 2.55” H x 1.02” D). It simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S.
