No Argument over here. It is not a good idea to go against MSDS in any case - and in some cases - the side effect is quite permanent. The descation here is very specific to potassium dichromate and so are my remarks. For example - lead is also a poison - but I'm sure most members touch lead and live to tell about it. The MSDS describing lead as poison is aimed in that case for people with long exposure as well.You don't have to have first hand experience feeling the side effects of a chemical to know what it will do to you. In fact that's why they come with MSDS so you can PREVENT contact; as I did.
Linseed protects in most cases one big acceptation is protection from ammonium perchlorate where K2Cr2O7 is a must.
It's important for members to remember that MSDS are there to protect you - and you should never go against what is written by them unless monitored by an experience person and after you made sure you received advise from reliable and knowledgable people. When saying "reliable and knowledgable" - that means someone who deals with the chemicals on every day basis. In potassium Dichromate case - that probably means someone outside the forum.
The one point I can make is that Dichromate is more effective then Linseed in a variety of cases - and not only when it comes to ammonium perchlorate. The difference between the two is the protection method. Linseed creates external coating - which can drip on a hot day, slow combustion and rander some compositions useless. Potassium Dichromate is quite different and provides a chemical protection by creating a layer that is not easily destroyed. It is used almost exclusively by the industry - but for the amateur linseed is a simple, effective and safe method of protection.
