Description

Self-adhesive labels printed with reactive ink to control facepiece mask decontamination by UV-C radiation. 5 rolls numbered from 1 to 5 to indicate the number of reprocessing cycles.

Chemdye® ChemDose CD87-1000M chemical indicator has been specially developed to control N95 y FFP2 respirators disinfection processes by UVGI. It consists of a 15 mm diameter dot of a self-adhesive synthetic substrate printed with reactive indicating ink.

This ink has been calibrated to experience different color changes depending on the accumulated UVGI dose received, which allows to quickly and accurately control the efficacy of the disinfection process. Chemdye® ChemDose CD87-1000M chemical indicator consists of five rolls numbered from 1 to 5, which allows the end-user to easily identify the amount of times their respirator has been reprocessed.

Instructions for use

1.Before running the first disinfection process of the respirator, take off two Chemdye® ChemDose CD87-1000M chemical indicators from roll 1 and stick one of them onto the external surface and the other one onto the internal surface.

2.Run a normal disinfection process.

3.Once the process has finished, contrast the final color reached by both Chemdye® ChemDose CD87-1000M chemical indicators against the Reference Color Card provided in order to determine the UVGI dose received.

NOTE 1: in case one or none of the chemical indicators Chemdye® ChemDose CD87-1000M reaches de final color corresponding to the minimum UVGI dose required (1000 mJ/cm2), the disinfection process must be repeated following the indicated procedure in points 2.- to 3.

Otherwise, if both Chemdye® ChemDose CD87-1000M chemical indicators reach the final color corresponding to the minimum UVGI dose required, it can be considered the disinfection process has been effective and the respirator can continue to be used.

Before continue using the respirator, remove the Chemdye® ChemDose CD87-1000M chemical indicator that had been sticked onto the internal surface, but keep the one that had been sticked onto the external surface.

4. Before running the second disinfection process of the respirator, take off two Chemdye® ChemDose CD87-1000M chemical indicators from roll 2 and stick one of them onto the Chemdye® ChemDose CD87-1000M chemical indicator that had been used in the previous disinfection process and the other one onto the internal surface.

5.Run a normal disinfection process.

6.Once the process has finished, check the final color reached by both Chemdye® ChemDose CD87-1000M chemical indicators. A red final color corresponds to the minimum UVGI dose required of 1000 mJ/cm2 .NOTE 2: in case one or none of the chemical indicators Chemdye® ChemDose CD87-1000M reaches de final color corresponding to the minimum UVGI dose required (1000 mJ/cm2), the disinfection process must be repeated following the indicated procedure in points 5.- to  6.

Otherwise, if both Chemdye® ChemDose CD87-1000M chemical indicators reach the final color corresponding to the minimum UVGI dose required, it can be considered the disinfection process has been effective and the respirator can continue to be used.

Before continue using the respirator, remove the Chemdye® ChemDose CD87-1000M chemical indicator that had been sticked onto the internal surface, but keep the one that had been sticked onto the external surface.

7.Repeat the procedure indicated in points 4.- to 6.- for the third, fourth and fifth disinfection processes.

NOTE 3: exposed and non-exposed Chemdye® ChemDose CD87-1000M chemical indicators must be kept protected from light. Non-exposed Chemdye® ChemDose CD87-1000M chemical indicators must be removed from its original packaging ONLY right before running the disinfection process.

Between two disinfection processes, the exposed Chemdye® ChemDose CD87-1000M chemical indicator that remains sticked onto the external surface of the respirator while it is being used, may change its color with respect to the one reached at the end of the disinfection process.
