Suresign Alcohol Screening Test - Twin Pack
The Breath Alcohol Detector is for rapid detection of the presence of alcohol in the exhaled breath and provides relative Blood Alcohol Concentration (BAC) at 0.05%.
The test is based on a chemically chromogenic reaction. Alcohol, if present in the exhaled breath, reacts with the chemically coated crystals and produces a colour change. This colour change is proportional to the concentration of alcohol in the breath, which is an approximation of relative Blood Alcohol Concentration (BAC).
How to use
Allow the test to reach room temperature (15-30°C) prior to testing. Wait 15 minutes after last alcohol consumption or drink a glass of water before taking the
1. Bring the pouch to room temperature before opening and use it as soon as possible.
2. Remove the detector from the sealed pouch by tearing the sealed pouch at the pre-cut mark to avoid touching the Mouthpiece. Do not touch the Mouthpiece to avoid any
3. Hold the middle of the detector using your left and right index finger and thumb, then firmly squeeze the detector to break the Inner Glass Tube containing the yellow
crystals. Do not crush or bend the detector. Perform the test as soon as possible after breaking the Inner Glass Tube. Refer to the illustration at right.
4. Hold the middle of the detector horizontally, then take a deep breath and blow hard into the mouthpiece of the detector in one continuous breath for 12
seconds. Then shake the detector slightly to distribute the crystals evenly in the Test Window. Note: Failure to blow hard or to blow in one continuous breath for 12
seconds into the detector may cause erroneous results. Do not inhale while blowing into the detector. Refer to the illustration at right.
5. Read results at 2 minutes by identifying the colour of the crystals to determine the relative Blood Alcohol Concentration (BAC). Do not read results after 5 minutes.
Warnings and Cautions
1. Alcohol impairs judgment. The test should be performed and the results should be read by someone who has not been drinking to ensure accurate results.
2. The Breath Alcohol Detector provides only a preliminary result for the relative Blood Alcohol Concentration (BAC). A secondary analytical method using an evidentiary alcohol test must be used to
obtain a confirmed result and before taking any legal or workplace actions.
3. The test can produce erroneous results due to possible contamination of the breath by interfering substances. Wait at least 15 minutes after last alcohol consumption or drink a glass of water before
taking the test to remove alcohol vapours from mouth because it may cause false positive results.
4. Ingestion or general use of over-the-counter medications and products containing alcohol such as cold medicines, breath sprays and mouthwashes can produce false positive results. Wait at least 15
minutes after ingesting such products before taking the test.
5. Results should not be interpreted by users who are colour-blind or visually impaired. Interpretation of visual results is dependent on variability of colour perception and the lighting conditions when the test
is read. For best results, read under incandescent, fluorescent, or indirect sunlight. Results read under street lights (sodium vapour) may cause green to look grey-green and blue to look amber-green, use a
flashlight to read the results under these lighting conditions. When using a flashlight, ensure that the light falls on the side and does not fall directly on the detector.
6. Due to certain factors including sex, age, physical condition, and amount of food or drugs consumed, a person who may have tested negative from the test may display signs of intoxication or impaired
7. The test is highly sensitive to the presence of alcohol. Alcohol vapours in the air can be detected by the test. Alcohol is a component in many household products such as disinfectant, deodorizers,
perfumes, and glass cleaners, and is present in homes and many institutions. If the presence of alcohol vapours is suspected, the test should be performed in an area known to be free of vapours for
8. All Alcohol Screening Test results are ADVISORY ONLY as incorrect use can cause erroneous results. Users must use their judgment, taking
into account all available information, including the amount of alcohol consumed and the time lapsed since consumption, as to whether they
are capable of driving or carrying out dangerous tasks.
