Why should we test the level of chlorine in our bleach?
The amount of available chlorine in bleach decreases with factors such as age and exposure to heat, sunlight, and contaminants. If your bleach solution is being used for disinfection purposes, it is important to be able to check its chlorine level for adequacy.
How often should we test our bleach?
If your bleach is being manually diluted with water and contained in a spray bottle or squeeze bottle, it should either be made fresh daily or tested daily.
What if the color on the strip pad doesn’t match any of the color patches on the label chart exactly?
The colors don’t have to match exactly; however, to determine an accurate match, evaluate the degree of yellow pigment on the strip pad compared to the color patches on the label chart. It can be helpful to obtain a consensus among 2 or 3 people if matching is difficult. Just remember to make the evaluation within 10 seconds after the initial 30-second color-development interval.
Can we spray the bleach on the strip instead of dipping the strip into the bleach?
Safety and accuracy are best achieved by dipping the strip into the bleach solution.
GENERAL USE DIRECTIONS
Do not leave vials open while testing; snap vial lid shut immediately after removing a test strip. On the bottom of the vial label, record the date the vial us first opened. Use the strips within 2 years of the recorded date.
- Dispense a sample of the bleach solution to be tested into a small, clean container.
- Dip the square pad at the end of the test strip into the bleach solution for 1 second.
- Remove it from the solution and wait 30 seconds to let the color develop.
- Within the next 10 seconds, evaluate the color of the pad by starting at the 10,000 ppm patch on the label chart. Carefully compare the color of the pad to the chart, evaluating the degree of yellow pigment to determine the best match. The color of the pad may not be perfectly uniform; this is normal.
