Where does ethanol gas go in an enclosed space?

Click For Summary

Discussion Overview

The discussion revolves around the behavior of ethanol vapor in an enclosed space, particularly focusing on its accumulation, dissolution, and the implications of exposure in contexts such as classrooms. Participants explore theoretical and practical aspects of ethanol vapor dynamics, including diffusion, condensation, and potential interactions with surfaces.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that ethanol vapor may remain in suspension and spread evenly throughout an enclosed space, similar to water vapor.
  • Others propose that ethanol vapor could condense, react, or interact with other materials in the room.
  • A participant questions the meaning of "dissolve" in this context, seeking clarification on the behavior of ethanol vapor in a classroom setting after using hand sanitizer.
  • There is a discussion about the time it may take for ethanol fumes to disperse or settle, with estimates varying based on the type of sanitizer used.
  • Some participants express concern about the implications of ethanol exposure in relation to drug testing, particularly regarding the sensitivity of tests for EtG, a byproduct of ethanol.
  • One participant draws an analogy to poppy seeds and drug testing, emphasizing that legal parameters and cutoff values play a significant role in interpreting test results.
  • There are inquiries about the specifics of how tests are performed and the relevance of the concentration of ethanol vapor in relation to detection limits.

Areas of Agreement / Disagreement

Participants express a range of views on the behavior of ethanol vapor, with no clear consensus on how it behaves in enclosed spaces or the implications of exposure. The discussion remains unresolved regarding the specifics of ethanol vapor dynamics and its effects on drug testing.

Contextual Notes

Participants highlight the importance of legal definitions and parameters in interpreting drug test results, indicating that scientific understanding alone may not suffice to address the concerns raised. The discussion also reflects uncertainty regarding the exact conditions affecting ethanol vapor behavior.

It looks like the short answer is "it depends"... ie. nobody can know if the articular testing protocol followed by your workplace will have a chance of a job-threatening false positive from the hand sanitizer supplied. You need to know how the test is used.

The people to talk to would be the people doing/administering the test - you are concerned that routine hand sanitizer use could lead to a false positive in your required drug testing - can you get a clarification on this. You can also check with a union rep to see if there is a problem with this sort of thing.

There is a possible downside in which the possibility that some people, worried about a legit positive, may want to muddy the issue by using hand sanitizer - introducing a plausible deniability - and leading to people with a genuine concern about false positives getting tarred with the same brush.

Sometimes these tests are available commercially as a small kit - in which case you can do some experiments specific to your workplace, to see if your concerns can be supported by direct evidence.

You still need to know how the test is administered though. For instance, if the workplace has a zero tolerance policy, then the slightest trace may be bad, but if they just want to make sure that employees in your position are not alchoholics or routine drug users, then small traces are unlikely to be an issue ... a positive test may just result in an investigation, it's a matter of policy.

If this is a serious concern, especially if you are not the only one, then maybe there is a case for switching to an alchohol-free hand sanitizer?

How does this come up? Is this a new policy? How long has the hand sanitizer in question been used in the workplace while there has been this sort of testing going on? How long have you worked there? Etc.

But have you noticed how the responses are much better now that your actual concern has been voiced?
To answer your question, my brother who is a RN, explained that inhalation exposure to ethanol could cause a false positive for EtG/EtS. Until that point I had been advised to abstain from skin exposure to or ingestion of products containing ethyl alcohol. My concern stems from potential legal repercussions for failing a drug test.

Well that looks like a get out of jail free card for his employer. You are required to use a product that will pretty much guarantee failing the test. Something like 100% of your workforce will fail the drug test at any time. If you want someone gone for any reason just test them. Now you can fire them for fault.

Although I've never ran across an issue with regards to EtG, I have a lot riding on this and am extremely cautious when it comes to things like this.

Is this 100ng limit a zero tolerance policy? As in you test over for any reason even once you are done?

Yes.

I would suggest you demand they stop using ethanol based sanitizers. There are non alcohol versions as well as isopropyl based ones. It seems cruel to expose you to something then require you be free of the substance they exposed you to.

Kind of like a bully punching you and demanding you stop hitting their hand with your face.

So has there been an issue with high numbers of coworkers being fired for failing this test in the past?
Have you brought up your concerns with your employer? Your union rep? Coworkers?
