EH40 lists R65 as:
"Harmful: may cause lung damage if swallowed"
Can anyone explain the mechanism how you can damage the lungs by swallowing...

Swallow substance, choke it up and then aspirate it into the lungs...
Problem with oils and the like apparently.

Fantastic! Thanks very much for the extremely swift response.
(I am sure there is a nasty analogy there somewhere, involving an alcohol/fast food/friday night combination)
I am no longer miffed and slightly less thick.

There are many chemicals, paraquat to name one, that are ingested through the mouth and while damage is caused to the mouth and throat at the time, the major damage occurs when the chemical spreads through the bloodstream to cause damage to the lungs, kidneys and liver. Some of these chemicals (mainly ones available as agricultural or horticultural agents) also contain emetics to cause vomiting if swallowed.

Apparently, this used to be a problem when lighting came from light oil lamps. The oils were sweet smelling and children were known to drink the stuff because of this. Being rsponsible adults the parents would make their children throw up and in the process help the child breathe in the oil at which stage it would coat the lungs and effectively suffocate the child. There is a weight/viscosity below which all oils have to carry a warning to this effect. From what I understand most low toxicity synthetic light oils these days are better left to go through the system. Read the MSDS before assuming that yours is one of these.
Best Regards

When I worked in Rover Group 15 year ago we had 12,000 subsbtances on the COSHH database and 20 new ones to assess each month. We reckoned that about 10% of all supplier's datasheets were wrong - and I don't just mean minor errors - There was the water-based paint marked highly flammable for example. More recently I came across a simple contact adhesive where the datasheet and label didn't match. On contacting the supplier's H&S guy we found that BOTH were wrong, and he was working his way through the whole product range correcting errors. Apparently the glue concerned had been labelled like that for 10 years and no-one else had noticed...
Don't believe what you read....

Yep, that's the old MSDS scam.
The metal we use comes in already painted, with "pre-weld primer"
According to the MSDS, it's the best thing since sliced bread. But the welders felt ill after welding it for a time. Checked the MSDS for where it had been tested....a univ up north.
So, went through the union and got the name of a tech in the labs....
Some test....max thickness in the test .... 10 microns...max thickness on the metal...over 120 microns.
So, the paint that was to be welded through had actually been tested in welding ?
No.
It had been burnt off in controlled conditions with an electric arc...in an inert gas atmosphere.
Some MSDS.
Funny how the ones you get in the UK are very different to the ones filed in the usa ?
