I would only imagine it is used to just clean or keep the area clean and act as a disinfectant. Most soaps do have a pH of around 9. So it not being a strong base, for an acid burn it may help neutralize the acid and limit the burn. I would not think this would be the main reason to use it.

Does anyone have an idea of why (M)SDS so often recommend "wash gently with soap and plenty of water"? What is the soap supposed to do? My understanding is that soap primarily acts by dissolving grease; dissolving grease releases dirt; water washes away dirt. Is there a significant fat/oil/grease component to a TFA splash? Are we just reading boiler plate washing instructions?

Subject: [DCHAS-L] Question on trifluoracetic acid & emergencies

 

One of the labs on campus asked about having an HF emergency kit for trifluoracetic acid use. 

 

I need the collective wisdom of his group - yes? no? references? (the SDS doesn't mention anything about this)

 

Thanks
