Discussion Overview

The discussion revolves around the properties and handling of Novec 1230, also known as Sapphire, a fire suppressant material developed by 3M and Ansul. Participants explore its physical characteristics, safety concerns, and comparisons to water and alcohol, focusing on its behavior as a fire suppressant and its implications for use in fire safety applications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes that Novec 1230 behaves similarly to water but is non-conducting and non-destructive, raising questions about its handling and physical properties such as weight and viscosity.
  • Another participant highlights that Novec 1230 evaporates approximately 25 times faster than water, suggesting it may feel cold to the touch and evaporate like alcohol.
  • Concerns are raised about the potential health and safety hazards of Novec 1230, including its rapid absorption through the skin and the risks associated with fluorinated organic compounds when exposed to fire.
  • A participant questions whether Novec 1230 burns when mixed with air, while affirming its ability to evaporate and carry off combustion heat effectively.

Areas of Agreement / Disagreement

Participants express varying opinions on the safety and handling of Novec 1230, with some emphasizing its potential hazards while others focus on its effectiveness as a fire suppressant. The discussion remains unresolved regarding the overall safety and practical implications of using this material.

Contextual Notes

Participants mention the normal boiling point of Novec 1230 and its comparison to chloroform, indicating potential limitations in understanding its handling characteristics and safety. There are also concerns about marketing downplaying health risks.

I just saw an article on TV about this new material by 3M called Novec 1230 (or Sapphire by Ansul) that looks and acts much like water, but isn't.

It's non-conducting and non-destructive. I was wondering what this material would be like to handle. I wondered how hard it would be to tell that it was not water, by, say, weight, vicosity or other.

But they mention that it evaporates about 25x faster than water. It seems to me, that it would appear and behave very much like alcohol - it would be cold to the touch and would noticeably evaporate like alcohol does.

I wonder if it is aromatically volatile like alcohol (though they seem to have no problem with large, open containers of the stuff.)

I should have added that I have been looking around a bit, but I haven't found anything that talks about what it's like to handle or touch.
 
Normal boiling point is 49 C --- that give you any hints? Be about like chloroform. Plus, it might be absorbed fairly rapidly through the skin --- plus, the health and safety hazards are downplayed for marketing purposes --- plus, you throw any fluorinated organic compound into a fire you get HF. Does it burn if mixed with air? No. Does it evaporate and carry off a lot of combustion heat? Yes. Enough to quench enough different fire types to make it useful? Yes. Do you want to be in the room with it? No.
