Hi, I’m Wesley with Accutec-IHS. The AccuFIT9000 is a new instrument for performing respirator fit testing which depends on measuring the fit of a tight fitting respirator by comparing the ratio of the respirable particles in the breathing zone, with the concentration of these ultra-fine particles in the ambient atmosphere. This technology is called condensation particulate counting. To learn more, watch the video condensation particulate counting on the AccuFIT9000. 

          Let’s ensure the instrument is working properly, remove the instrument from the carrying case and locate the power supply AC cord, alcohol capsule sample tubing, and HEPA filter. Plug the power supply into an electric outlet. Connect the power supply and plug the connector into the port on the back panel of the AccuFIT9000. Next, remove the alcohol wick assembly from the capsule and place it on a clean surface. Then pour reagent grade isopropyl alcohol which is supplied with the instrument into the capsule so that the level of liquid is above the bottom line and below the top line. Replace the alcohol wick into the capsule and allow the alcohol to saturate the wick. This takes about two minutes. Remove the wick assembly from the capsule and tap off any excessive alcohol. Then remove the storage cap from the AccuFIT9000 alcohol port and replace it with the saturated alcohol wick. The locating pin and camming groove on the cap will guide the wick into its proper location. Now attach the sample tube to the a AccuFIT9000 making sure that you attach the blue tube to the blue inlet and the clear tube to the silver Inlet. Attach the HEPA filter to the clear tube making sure that the arrow showing flow direction is pointing toward the tube. Now press and hold the on/off button on the AccuFIT9000 until it illuminates with a red light. Allow the instrument to complete its warm-up and internal self checks. This takes about a minute and then will automatically transition to the opening screen.  The on/off button will now illuminate green. Touch the administration icon and then select the database icon using the drop down arrow. Highlight demo and then touch the load button. A message should appear telling you that the database demo is successfully loaded into active memory. Please note that the demo database does not allow you to perform all of the functions to test the instrument. It does not allow you to add names, respirators, or protocols to memory, nor does it allow you to save any results obtained. Press exit and then the return arrow on the previous screen. This returns you to the opening screen.

          Now it is time to test the functionality of the AccuFIT9000. Touch the icon labeled validation check, remove the HEPA filter from the clear tube and press start. The AccuFIT9000 will now measure the ambient particles and produce account. The validation check will now ask you to replace the HEPA filter into the clear tube and press next. The validation check will proceed automatically to check that there are no internal leaks in the system, that the switching valve is functioning properly, and that the unit can calculate the max fit factor. You have now demonstrated that the AccuFIT9000 is performing as designed. To shut down the instrument, hold the on/off button until it flashes red and green and touch the yes box. It is very important to remove the alcohol cartridge and replace it with the storage cap. Failure to remove the alcohol cartridge can result in alcohol contamination of the optics. Replace the alcohol cartridge into the   capsule. This ensures that there will be no spillage and that the alcohol cartridge will be ready to use the next time you want to perform fit testing. If the AccuFIT9000 is to be stored in the carrying case, remove the sample tube and power connector, and place the cutouts in the protective foam insert and position the instrument appropriately.

Protect Against the Coronavirus With Respirator Fit Testing

Both CDC (Centers for Disease Control) and WHO (World Health Organization) have now recognized the 2019-nCoV coronavirus outbreak as being serious. One of the more concerning developments is the fact that 2019-nCoV has shown to be capable of human-to-human transmission. This was first documented in this country today, January 30, 2020, in Chicago where a recently returned visitor from China has infected her husband.

Because of this demonstrated ability of the new virus to effect human-to-human transmission, CDC has issued guidelines for health professionals which can be accessed at the bottom of this page:

One of the recommendations the CDC Document mentions is the use of respiratory protection. Typically, healthcare facilities use N95 Filtering Facepieces (FFP’s) or powered air-purifying respirators (PAPR’s). PAPR’s need to be cleaned and disinfected after each use, while FFP’s are discarded after each exposure to airborne pathogens, so the chances are greater that N95 FFP’s will be the respiratory protection devices of choice.

AccuTec-IHS would like to remind users that it is imperative that fit testing in accordance with 29CFR 1910.134 be performed for each user of the tight-fitting respirators (in this case N95 FFP’s). From personal experience we can state that even though the techniques of donning, testing, and wearing an N95 FFP appear to be logical and straightforward, in reality if the user has not been adequately trained, the mask is worse than useless because it imparts a false sense of security to the wearer. This training should incorporate a Quantitative Fit Testing device where real-time and completely objective measurements can show the user graphic proof of protection while the mask is being adjusted to fit. (This real-time information is for training purposes and does not constitute a fit test.)

OSHA has recently approved a much faster Quantitative Fit Test protocol for the filtering facepieces (N95) which takes less than three minutes to perform. A legal Qualitative (i.e., subjective fit test) requires about twenty-three minutes. 

The AccuFIT9000 is capable of testing many of the commonly used N95 masks.

New Quantitative Fit Testing Technology

I am Connor O’Donnell, cofounder of Accutec-IHS. Our flagship product is the AccuFIT9000 quantitative respirator fit test instrument. Accutec-IHS was founded in 2016 with a mission to bring a fresh new respirator fit tester to market. Here’s why. For nearly 30 years, there were only two manufacturers capable of performing the OSHA fit test protocol. One was the controlled negative pressure method and the other was the condensation nuclei counting method. Our founders and consultants have over 75 years of combined respirator fit tester experience, so we knew early on that we would use the CNC method, which allows a respirator to be tested in a dynamic manner. Frankly, if a respirator is going to leak, it’s going to leak while you’re talking, breathing, moving your head and performing basic work functions, not while you’re holding your breath. To differentiate ourselves from our competition, we listened to the voice of the customer.

Because of this, we were able to build in some exciting new features, including standalone mode, built in wifi, and some unique programming, which allows us to be the first respirator fit test or on the market with wireless operator mode. Wireless operator mode allows a person to control one to four units with a tablet, with independent start and stop times while still relaying the instructions to the fit test subject on the builtin display on the instrument. It core value of Accutec is to achieve total customer satisfaction. We stand 110% behind our product and honestly strive to continuously improve. For example, the AccuFIT9000 carries an industry leading three year warranty. When you make a decision to buy an AccuFIT9000 you’re not only buying a great instrument, but you’re getting a partner in your respirator fit testing endeavor.
