Whenever police use an approved instrument in Ontario they also use Accessory Equipment. Accessory Equipment in Ontario includes the Wet-Bath Simulator that holds the alcohol standard and the Simulator Thermometer that verifies the temperature of the alcohol standard in the wet-bath simulator. The most commonly used wet-bath simulator in Ontario is the Guth 2100.

The purpose of a wet-bath #duisimulator, such as a Guth 2100, is to hold the full contents of a 500 ml bottle of liquid alcohol standard. The alcohol standard comes from a lab such as Calwave, ACS, or Laboratoire Atlas. The bottles usually come in a box of six. Some bottles from every batch or lot are tested by an Analyst at the CFS resulting in a Certificate of the Analyst.

 

ATC, CFS, and the manufacturers of the standards require that the temperature of the entire liquid contents of the #duisimulator be maintained at 34.0 ±.2° C. during any calibration checks. It says this right on the bottle. A simulator is accessory equipment according to the Alcohol Test Committee. It, as with all accessory equipment, must be inspected annually to ensure maintenance of manufacturer's specifications. Manufacturer's specifications on the Guth 2100 are 34.00 ±.05° C.

 

The contents of the simulator are changed about once a week or once every two weeks. A qualified technician at the detachment (who probably won't be the same one who tested your client) takes a bottle out of the box.  The QT checks the Certificate of the Analyst that confirmed the concentration of that lot of alcohol standard at the CFS. Any old incoming alphanumeric seal number is recorded in the officer's notes and in the Alcohol Standard Log. The jar is unscrewed and the contents are dumped. The jar is rinsed and inspected for chips & cracks. The new bottle is opened carefully so that the contents are not contaminated by the sharp object used to break the seals on the top of the bottle. The entire bottle contents are carefully dumped into the jar. The housing is carefully lowered into the jar (so as not to damage the simulator probes) and screwed onto the jar for a snug fit but not so tight as to break the edges of the jar. The details of the new bottle are recorded in the officer's notes and the Alcohol Standard Log. A new alphanumeric seal is attached and its details are recorded. All steps should be completed in accordance with the standard operating procedures (SOPs) for the police service.

 

If the approved instrument is an 8000C, the qualified technician must complete the Configuring the Alcohol Standard sequence to activate the CalGuard feature.

 

After checking the tubing system for leaks, the Qualified Technician then runs an Esc Esc C stand-alone cal check sequence to conduct a calibration check. The temperature of the alcohol standard is checked using one (or more) of three possible simulator thermometers.

 

The wet-bath simulator and alcohol standard are now ready for use by a subsequent Qualified Technician conducting subject breath tests.
