Another stinging eyes victim here. Luckily only seems to last a couple of hours up until now.


Edit to add:
From Wiki - https://en.wikipedia.org/wiki/Cyanoacrylate

The fumes from cyanoacrylate are a vaporized form of the cyanoacrylate monomer that irritate the sensitive mucous membranes of the respiratory tract (i.e., eyes, nose, throat, and lungs). They are immediately polymerized by the moisture in the membranes and become inert. These risks can be minimized by using cyanoacrylate in well-ventilated areas. About 5% of the population can become sensitized to cyanoacrylate fumes after repeated exposure, resulting in flu-like symptoms.[27] Cyanoacrylate may also be a skin irritant, causing an allergic skin reaction. The American Conference of Governmental Industrial Hygienists (ACGIH) assign a threshold limit value exposure limit of 200 parts per billion. On rare occasions, inhalation may trigger asthma. There is no singular measurement of toxicity for all cyanoacrylate adhesives because of the large number of adhesives that contain various cyanoacrylate formulations.

G'Day Gents

That, seems to nail it, Thank you Exile, mine does seem to be better by having the window open and the fan going, Mind you, it doesn't help having Emphysema. It would seem I'm going be a lot more careful in the future.

Thank's manna.

Sounds like you are both becoming sensitised towards it. As superglue contains cyanide, its a fairly nasty thing for anything containing er life, or moisture.

Please do not take any notice of the cyanide comment above.

Cyanoacrylates do indeed contain a cyanide group and as such it is completely harmless - unlike inorganic cyanides which as suggested are deadly. It is easy to become emotive if you come across the term cyanide and assume that all molecules containing cyanide must be deadly. They are not.

Cyanoacrylates were developed to provide battlefront sutures - basically gluing wounds back together - and as such now have FDA approval for use in normal medical situation. FDA would not give such approval if there were even the slightest hint of the cyanide group causing a problem.

For anyone modelling the GER (just to keep this on track), the Prussian Blue pigment used on pre-WW1 locos is a potassium iron hexa-cyanide compound. It does not kill people - in fact it is also used to cure people who have some uncommon forms of poisoning.
