EPA is conducting several studies to inform the response to the COVID-19 public health emergency. Because the disinfectant chemical fog can fill a room, they are usually operated automatically with no operator present. Example photographs of a clip-on lamp, before and after spraying fluorescent dye solution. The sprayer was running for a few seconds before placing the nozzle in the container and starting the timer. Figure 2. This recall was conducted, voluntarily by the company, under CPSCs Fast Track Recall process. Vapor phase measurements of the active ingredient were conducted during the spray process, i.e., we measured chlorine gas when spraying a dichlor-based disinfectant and hydrogen peroxide vapor when spraying the hydrogen peroxide-based disinfectant. (For the Clorox 360 sprayer, we used both tap and DI water as the diluent in these tests, to evaluate whether the lack of ions in the water affected deposition.) Lett., https://dx.doi.org/10.1021/acs.estlett.0c00966, Available chlorine concentration (ppm) of disinfectant. The results are averaged across the five sprayer configurations tested, for the coupon orientation (horizontal or vertical) and material. The results for the wetness tests are summarized in Figure 6 and show the amount of water recovered from the test coupons initially after spraying (the positive controls) and after 10 minutes of drying time. 6.This device was not tested for spray charge due to the sprayer becoming non-functioning after the DSD tests. No surface coverage rates were recommended for the foggers, consistent with the approach that foggers are typically intended to be used as a volumetric (aerosol) decontamination device rather than strictly for application of disinfectant to surfaces. Env. The electrostatic charge results are shown in the last column of Table 1. ft. per tank of fluid, $699.99, BACKPACK SPRAYER Covers 23,000 sq. Victory Innovations toll-free at 888-674-2482 Monday to Friday from 8 a.m. to 5 p.m. The wireless earphones can overheat while charging or in use, posing burn and fire hazards. This parameter is critical to ensure that sufficient disinfectant volume is applied to the surface such that it remains wet for the required contact time of the disinfectant, and thus ensures effective inactivation of the virus (and compliance with the EPA-required disinfectant label). Its safe to use in confined spaces or high-traffic areas, like classrooms and offices. Following each sprayer evaluation, the three trash cans were washed with a laboratory-grade detergent, and then further cleaned using a mixture of isopropyl alcohol and acetic acid. Other parameters may introduce exposure concerns by creating inhalation hazards to the operator of the ESS or those occupying the space following disinfection. Another ESS has the ability to turn the electrostatic charge on and off; both settings are being evaluated. When collecting the disinfectant droplets in the glass beakers, the spray time was typically 1.5 minutes. The test apparatus used to measure spray charge consisted of an aluminum plate 20.1 in. The electrostatic charge imparted to the spray, potentially affecting its ability to deposit onto surfaces, including surfaces not in the direct path of the spray (e.g., the ability to wrap around and adhere to complex surfaces). Temperature in the test chamber was controlled to approximately 21 C and relative humidity was controlled to approximately 35%; air flow in the test chamber was approximately 1 m/s. 1.Range in average results based on tests done with DI and tap water, at 3-4 different distances. This concentration is lower than the National Institute of Occupational Safety and Health recommended exposure limit (15-minute average) for chlorine gas of 0.5 ppmv. The manufacturer recommended disinfectant surface coverage rates ranged from 2-53 ounces of disinfectant per 1000 ft2 for those ESS for which information was available. The test results also showed that the presence of ions in the water had no effect on the DSD (i.e., comparing deionized and tap water), and the use of disinfectants also had no effect on the DSD as well (see Figure 2 for example data). The summary here is intended to provide a simple representation of the results of on-going testing; therefore, only a brief description of the purpose of the study, methods, and interim results are provided. The charge-mass ratio (Q/m) was determined by calculating the average current measured from the three tests divided by the mass flow rate. For one of the ESS devices evaluated, the electrostatic charge function can be turned on and off, and so the DSD was measured for both settings. This study is being conducted in accordance with an approved Quality Assurance Project Plan. Two of the ESS we are evaluating use alternating current (i.e., they are plugged in), while the rest rely on battery power. The underside of the lamp also seems to be well illuminated, indicating deposition, although individual droplets are not as visible as they are on the right side of the lamp. There was no loss in the disinfectant available chlorine level (free hypochlorite/hypochlorous acid and combined from dichlor) as measured from the sprayer reservoir, when collected at the nozzle, and when sprayed and then collected 3 feet away. The portion of the right-side image near the back of the lamp (opposite of where it was sprayed) does appear somewhat darker, indicating less deposition. Total concentration of free and combined chlorine from dichlor. Sprayers are used to apply disinfectant directly to a surface (recommended spray distances vary from about 2 feet to 10 feet), whereas foggers may be used for disinfection of surfaces or volumes (i.e., disinfection of air, inactivation of aerosolized viral particles). Philadelphia; Institute of Physics; 1999. The sprayer output flow rates are presented in Table 1 in units of oz/min, and when considering the target deposition rate and surface area to be disinfected, provide an indication of the time required to dispense the disinfectant onto the surfaces to be disinfected. It attaches to pathogens on a molecular level, breaks down their cell walls through oxidation, and permanently destroys them. CPSC.gov is an official website of the United States government. Three replicate tests were conducted for each disinfectant. Figure 3 is a composite image of four photographs taken of the 3-inch by 3-inch squares in each quadrant for one of the trash cans, prior to spraying the fluorescent dye solution. The percent water loss after 10 minutes for coupons in the vertical orientation ranged from 78-95%, while the loss of water for coupons in the horizontal position ranged from 65-81%. Spray distances varied according to the sprayer, based on manufacturer recommendations, and coupons were sprayed until droplets started to visually coalesce on the surface.

Following the tests using water, the spray charge for one of the ESS was evaluated for the same three disinfectants used in the DSD tests to assess the impact the presence of the disinfectant might have on the charge. Official websites use .gov As expected, the fogger and hand-pumped sprayer showed no measurable electrostatic charge.

This process was repeated three times with the plate being wiped dry between each test. Results for the left side of the trash can are similar to the right side, i.e., a small amount of deposition occurred within the square, nearer to the front side. For each material/sprayer/orientation combination, one positive control coupon and three test coupons were used. During each spray, the sprayer was moved back and forth, so that the spray cone fully enveloped the can. (2004). Pitol, A.K. This attribute may be both an advantage and disadvantage: an ESS may allow less disinfectant to be used to cover a surface area, but with less disinfectant applied, disinfection efficacy may diminish if the surface does not remain wet for the required contact time. Available chlorine (free as hypochlorite/hypochlorous acid and combined from dichlor) was measured when using the dichlor-based disinfectant, using a commercially available method (Hach high-range bleach test kit; Method 10100, model CN-HRDT; Loveland, CO) adapted from ASTM Method D2022-89. Approximately 8 mL were dispensed in each spray test. The droplet size distribution (DSD) of a spray is typically characterized in terms of the volumetric median diameter (VMD), which refers to the droplet size in which half the volume of the spray is in droplets less than, and half of the volume of the spray is in droplets greater than, the VMD. We began this series of tests using a metal trash can (11 inch height, 8 inch diameter; purchased with a black matte finish), and then followed with a few additional tests to examine the spray deposition on objects with more complicated surfaces, such as a step ladder, a clip-on lamp, and fold-out chair. The free-available chlorine concentration of the prepared disinfectant (4,347 ppm) and as indicated on the label (4,306) were not significantly different from each other. Consumers should immediately stop using the recalled sprayers, remove the battery pack and dispose it in accordance with local laws for disposal of lithium-ion batteries, and contact Victory Innovations for a free replacement battery pack, including shipping.

Sci. There are several ESS parameters that may impact the disinfectants ability to inactivate the virus on surfaces, notwithstanding that an ESS is only as effective as the disinfectant chemical being sprayed (only EPA-approved disinfectants should be used for the SARS-CoV-2 virus and in accordance with the disinfectant products label).
