grouping chemicals as volatile?
« on: May 29, 2008, 09:02:48 PM »
Hi,

just wondering if there is a criteria (simple) for defining chemicals as being volatile (i.e. ? vapour pressure).

reason being that our workers (ground remediation) are readily exposed to volatile chemicals rather than non-volatile (or not so volatile) chemicals, and I was hoping to classify the chemicals that are an inhalation risk.

Thanks in advance.

You should have the MSDS sheets for all the chemicals, and those should indicate what dangers, if any the vapors will have

Your idea is vapor pressure.

Read the first two sentences:

You question makes no sense. You already know they are exposed to volatile chemicals, but you want to classify them as volatile. But if you already know they are volatile, they are already classified as volatile?

Huh?

at what vapor pressure (value) are chemicals classified as volatile?

I have a large list of chemicals that workers are exposed to, where i know some are volitile as you can smell them (hence exposed). Looking at the msds how can i tell that they will readily flash off.

is it as black and white as > x value= volatile?
