"Liquid chemical germicides intended for use in conjunction with a variety of articles that fit within the statutory definition of "device," such as operating instruments, medical examining tables, hospital scales, and other hospital equipment, also fall within the definition of "device" because they are considered accessories to these devices."

{Safety standards for inhaled air} "TLV-TWA guidelines that are levels that should not be exceeded during any 8-hour workday of a 40- hour workweek" "TLV-STEL guidelines which are 15-minute exposure levels that should not be exceeded during a workday."

Explanation of requirements under FIFRA for importing and exporting pesticides.

Pesticides designed to control microbial pests such as viruses and bacteria must have data proving their ability to kill these pests (known as efficacy). The guidance documents on this page describe current efficacy-related requirements.

In evaluating a pesticide registration application, EPA assesses a wide variety of potential human health and environmental effects associated with use of the product.

"EPA maintains the following list of cost estimates of studies required to support a pesticide’s registration. EPA uses these estimates when determining whether a pesticide use meets the economic incentive portion of the definition of a minor use. The estimates were obtained by EPA from independent laboratories and are adjusted for inflation annually, although they may also change when the Agency has new information on the cost of tests that satisfy data requirements.

EPA News Release: EPA Takes Action to Protect Public from Coronavirus Protection Scams

{Draeger tubes are used by OSHA for on-site testing of chlorine dioxide, though OSHA specifies that ClO2 levels should be tested with Dräger CH24301 tubes, which are for checking chlorine levels from 0.2 to 30 ppm.} DrägerTubes® are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals. A calibrated 100 ml sample of air is drawn through the tube with the Dräger accuro® bellows pump. If the targeted chemical(s) is present the reagent in the tube changes color and the length of the color change typically indicates the measured concentration.

****!!!!****!!!!**** (1991) {Is this back-up method? Or actually fully validated?} "Collection devide: An air sample is collected using a calibrated sampling pump and a midget fritted glass bubbler. The bubbler contains a collection solution of 0.02% potassium iodide (KI) in a sodium carbonate/sodium bicarbonate buffer." "Analytical Procedure: In the weakly basic solution, chlorine dioxide reacts with KI to form chlorite (ClO2¯) which is then determined by an ion chromatograph equipped with a conductivity detector and gradient pump." "The stock standard should be standardized at least monthly. It was noted during testing that this standard solution decreases in concentration approximately 4% per month. No significant difference in results was noted when sampling at different humidities. As shown in the mixture study, Cl2 does not interfere with the sampling or ion chromatographic analysis of ClO2 at the concentrations tested. Although a resultant 10% decrease in ClO2 and 7% increase in Cl2 concentrations occurred, this could have been due to the difficulty in generating both gases simultaneously. A mixture of ClO2 and Cl2 can be collected and analyzed together; however,Cl2 measurements are considered for screening purposes only. Further work is necessary to validate the KI/buffer sampling and IC analysis for Cl2.Detection limits are adequate if samples are taken for 240 min at 0.5 L/min"
