Based on a recent trip I made to Africa, industrialization & development is likely to be an attraction to people on the bottom of the economic barrel in a country. It's a problem that is not easily solved.Also, with respect to Bhopal, regardless of how the incident was caused (whether by sabotage or otherwise), the fact remains that multiple safety systems at the facility were disabled, any of which might have prevented the scope of the tragedy.Richard Rosera

Can't believe you said this. Go see.Maybe squatters should not move in next door to a chemical plant?
And the lawsuits filed after and even still today have to do with continuing health issues and sensitization. So this is another problem that won't go away until the last Bhopal victim, and perhaps their fist generation children are dead and gone.

Et al,In general (not necessarily speccific to the compound in question), most isocyanurates are sensitizers. This means that a single high-level airborne exposure can cause RADS (Reactive Airways Dysfunction Syndrome) or in others with more low-level chronic exposure, Occupational Asthma (there are specific published critera for this diagnosis), and there's a few who don't any meet all of the criteria and still are disabled.That whole disaster in Bhopal was with MIC. I've had to review every bit of the data. It causes pulmonary edema which was fatal in many cases.. There was no cyanide release. Maybe squatters should not move in next door to a chemical plant? It was there first. But a true tragedy and if a couple disgruntled employees had not done the wrong thing, it mght never have happened and the world would be a better place.Free medical advice is worth exactly what you pay for it, but if I had worn your mocassins and walked a mile, I think I'd consult the folks at the Johns Hopkins in Baltimore and go from there. Sir Osler founded the bedside teaching of medicine in America, and there's some darned good folks still there. There's some tests might done and maybe an improved treatment regimen.AlanAlan H.

Subject: Re: [DCHAS-L] Question on triglycidyl isocyanurate (TGIC)Of course it is. We need to look at adopting the UK rules for this whole bunch of chemicals. They don't care what isocyanate radical is attached to, it is regulated as a sensitizer whether it has actually been tested and found so or not.
