SingleShot Operating Instructions

Below are basic operation guidelines for the BACtrack SingleShot. For more detailed instructions and explanations, please read the BACtrack SingleShot Instructions.

Before you test: 

  • Read the instructions completely. 
  • Make sure the crystals are yellow before you test. 

 

    • Wait 15 minutes after last alcoholic drink. If the test subject cannot wait, have subject drink water and rinse out mouth to remove alcohol vapors from mouth and esophagus that could cause a false positive.  

       

       

    • Squeeze the middle of the detector between thumb and forefinger to break inner glass tube. 

      Squeeze only once--do not crush or bend tube. Use the detector immediately. 

       

    • Hold vertically so arrows on the "BLOW" end are pointing down. Blow hard into tube one consecutive breath for 12 seconds. Shake the detector side to side to distribute the crystals evenly in detector window. 

      Lay detector on flat surface and wait two minutes.

       

    • Read the results. 

      Positive Results: Most of crystals are a light AQUA (GREEN/BLUE, BLUE/GREEN) cast. This shows that the breath alcohol is at or above the level printed on the detector.
       

      Negative Results: Most of the crystals, are light YELLOW. This shows that the breath alcohol is below the level printed on the detector. The yellow does not have to match the unused detector. It may be a much lighter or paler yellow than an unused detector.
       
      • The color change may be difficult to see under certain lighting. For best results, read under lighting such as incandescent, fluorescent, or indirect sunlight. A flashlight with an incandescent bulb can be used to help read the result. Hold the flashlight to the side so that the light does not fall directly on the detector.
      • Compare results to an unused detector or to the yellow box above. If most of the crystals are not GREEN or BLUE (under the suggested lighting), then the result is negative.
      • Detector results may not be reliable if testing is not conducted according to these instructions.
       

       

Intended Use

 

The BACtrack® SingleShot™ is a test for alcohol in human breath. It is a disposable screening device for one-time use.
 
The SingleShot is based on indicator chemistry that changes color in the presence of breath that contains alcohol. See our website for more information on the chemistry of the detector. Detectors are calibrated to turn positive at or above a specific level of alcohol in the breath. This level is called the cut-off. The cut-off is printed on the left side of the detector label. For example, a SingleShot detector labeled 0.08% will turn positive when the breath contains or exceeds 0.08% alcohol.

Preparation and Storage

The SingleShot detector is ready to use. Use the detector immediately after breaking glass tube. Optimal storage conditions: 4 to 122°F or -15 to 50°C.
 
The lot number and “Use By” date is printed on the SingleShot or the package label. Do not use the detector after the “Use By” date.

Warnings, Precautions, and Limitations

Alcohol impairs judgement. Do not test yourself or drive if you have been drinking. Someone who has not been drinking should help conduct the test and read the result.
 
Do not use the detector if the glass tube containing crystals is broken or the crystals are not yellow before you begin step one of the instructions.
SingleShot results should not be interpreted by readers who are color-blind, visually impaired, or under the influence of alcohol or any other substance that may impair their vision or judgement.
SingleShot result is best viewed under white light (incandescent, fluorescent or indirect sunlight). It may be hard to read SingleShot results under certain streetlights or under dim lighting. Under yellow streetlights (sodium vapor), green colors may look gray-green; blue colors may look gray-white. Under blue-white streetlights (mercury vapor) yellow may look amber-green. A flashlight with an incandescent bulb, held to the side of the detector, may be used to help read the result under these lighting conditions.
Lighting studies were performed following NHTSA (National Highway Traffic Safety Administration) guidelines. SingleShot results were read under 5 lighting conditions. The results met the guidelines except for 1 reading. There was 1 false positive out of 1200 readings of the .04 detector for a sample that did not contain alcohol.
Compare the SingleShot result to the yellow box on this pamphlet or to an unused detector of the same lot number to help you see if the detector has turned GREEN or BLUE indicating a positive result.
Keep out of reach of children. Do not immerse in liquid.
DO NOT EAT the contents of the SingleShot--it contains potassium dichromate, a hazardous chemical. If eaten, induce vomiting and contact your doctor.
The SingleShot should only be used as a screening device and is only an indication of the possible presence of alcohol in the blood of the subject. Although breath alcohol levels have been shown to represent blood alcohol levels, the correlation depends on many factors. The exact level of alcohol in the blood cannot be accurately determined by using the detector.
The detector does not determine or detect the intoxication of the subject. Decision’s and/or actions based on the use of this device by any person shall be at person’s own risk.
A positive result should be taken as a warning that the subject may have detectable alcohol in their system. A positive result should be confirmed by an evidentiary alcohol test before any legal or workplace actions are taken.
 
There may be times that a person tests negative and later show that he/she is under the influence of alcohol or their judgement had been impaired by alcohol.
