The ToxiRAE Pro Single-Gas Detectors, manufactured by RAE Systems, were purchased by KYOSH in 2017. A replacement was needed for the aging and irreparable Quest SafeLog 100s, which were used for carbon monoxide (CO) and nitrogen dioxide (NO2) detection. The units themselves and parts were no longer being manufactured and existing part stocks were quickly dwindling. Because KYOSH responds relatively frequently to imminent danger calls concerning carbon monoxide, it is imperative to employee safety that KYOSH continuously has functional detectors. The SafeLogs could no longer provide that assurance.
Enter the ToxiRAE Pro. It is a complete replacement for the SafeLog detectors, as there are ToxiRAE Pros for CO detection and NO2 detection.
Physical Interface
TO DO: Location of lights, type of sensor installed, buttons, speaker, sensor, belt clip, charging/communication contacts
On-Screen Interface
TO DO: Items on main screen, menu, settings
Sampling
When using the ToxiRAE to detect either carbon monoxide or nitrogen dioxide, the following apply to both gases.
- Whether you're screening or conducting personal air monitoring, use the OSHA-93 Direct Reading Report for any direct read devices, including the ToxiRAE Pro.
ProRAE Studio II Software
Because this is a different brand of instrument from 3M (formerly Quest), a different application is used to interface with and download from the ToxiRAE Pro. This section will detail the various settings and nuances of the software and how to get your data from the ToxiRAE Pro and into a report format.
Unlike the 3M DMS application, ProRAE Studio II is available for download from the RAE Systems website. Download it from here: ProRAE Studio II | RAE Systems

Data and Results
In the ProRAE Studio II software, the Datalog tab can show a TWA/STEL report. It is important to note the nature of these two columns of computed data.
- The TWA column shows a sort of "running TWA." At any given time in the data, this column will show the time-weighted average up to that point. If you look 15 minutes down the datalog, you will have a 15-minute TWA. At 4 hours 30 minutes, you will have a 4.5-hour TWA. For Compliance, this does not provide any useful evidence. However, this would benefit an employer who is trying to ascertain a representative sampling over a shorter time frame.
- For example, Stuff Burners, Inc., has an employee that works at two workstations — one in the morning and one in the afternoon. They leave the monitor on him throughout the entire shift but note what time he switched stations. The first station generates a lot more CO than the second. Having a "running TWA," they can look at the TWA at the time he stopped working at the first station. They can note this TWA to let it represent the 8-hour TWA if someone were to work their entire shift at this station. They continue to let it run so they can see this employee's actual full-shift TWA.
- The STEL column shows a real-time average of only the last 15 minutes recorded. This explains the absence of data in the first 14 rows. STELs typically consider only 15-minute periods. This data is beneficial in that a quick scan through this column will show at what times the STEL was exceeded. The location or process could be inferred from this time data. Because there is no regulatory STEL for CO or NO₂, this will assist a Compliance action only when a general duty citation is to be based on the NIOSH STEL for NO₂.
