Posted By Chris Packham I know it is not yet Friday, but I could not resist this... A client has just sent me a safety data sheet for review. The product is a screen and keyboard cleaner for computers. Section 3 on composition of the product states: Demineralised water ~ CAS no. 7732-18-5 ~ 80-100% Section 4 states: Skin contact: Wash the skin immediately with soap and water. Section 8 states: Eye protection:- If risk of splashing, wear safety goggle or face shield. Hand protection:- Use suitable gloves if risk of skin contact. The most suitable glove must be chosen in consultation with the glove supplier, who can inform about the breakthrough time of the glove material. Section 12 (Ecological information): Not regarded as dangerous for the environment. At least I can agree with the last item! Chris

Posted By Chris Packham They don't say! However, a similar product from the same supplier indicates a preservative that is R43.

Posted By Ron Hunter I have 2 MSDS on my desk just now (presumably created at the request of an insistent customer) for - wait for it - SOAP. Apparently these products contain........soap. Sigh!

Posted By Adam Worth Chris - good to see an MSDS that goes against everything we've been saying about them :) I used to have a really old MSDS for water - nothing else just water! lots of advice like if product gets into eyes wash with plenty of water. I'll see if I can get a copy from my old lab :)

Posted By Chris Packham Adam - how about: Prolonged exposure to solid form causes tissue damage. Exposure to vapour form can cause severe burns. Excessive exposure to liquid form can cause dermatitis and asphyxiation. Ingestion causes increased urination, possibly nausea and, in excess, permanent damage to health. Major component of cancer tumours Withdrawal causes death. Almost certainly the cause of more human deaths than any other chemical known to man! Substance is, of course, dihydrogen monoxide, a comibnation of hydrogen (R12 - extremely flammable) and oxygen (R8 - may cause combustion in flammable materials). And we use this to put out fires!

Posted By Stuff4blokes When mixed with ethanol and trace esters, ingestion can cause inebriation, loss of inhibitions, loss of control of motor and speech functions, nausea, vomiting, loss of consciousness. Many reported cases of violence and subsequent imprisonment. May lead to addiction.

Posted By Chris Packham Nearly three hundred hits on this thread, but not one person has made the comment I was expecting - and that was actually my first reaction. (De-mineralised water + computer keyboard = ????) Chris

Posted By Chris Packham Adam I think water on a computer keyboard does a bit more than just wet it. I have seen water spilt on a keyboard. The results were "interesting" to say the least. Electronics and water are not happy bedfellows. Chris

Posted By mark pearson Well yes water and electricity don't mix... true However keyboard is a digital device (1 & 0) operating on up to 5V @ mA's. have had the misfortune to fix laptops and keyboards that people have spilt or more correctly flooded with coffee, tea, beer, coke and milk! (not all were at work im pleased to say) surprisingly enough a lot of them after removing the sticky gunk will work once more! You might find that the sds was produced by an automatic churning program like SDS professional not endorsing in any way or shape! and this system will just slap in the risk and safety phrases. Were i currently work we always get a chemist to review and verify prior to issue of the sds. We constantly get some ridiculous sds's from customers who find a "better" or "safer" product from our competitors yet a quick review of the sds often finds significant contradictions within it! fundamentally the two substances are generally the same base but reading the sds you would think that they were totally different. anyhow why buy screen cleaner? never heard or a damp lint free cloth? with a little say tap water? mark

Posted By Chris Packham Mark The reason the employee within my client wanted this product was primarily because they had read an article (Daily Mail, I think) about the number of bacteria on a keyboard and wanted to ensure that all those in their office were kept 'safe'. I totally agree with your comments on keyboards. It was just the concept of someone marketing water to be sprayed on to a keyboard that intrigued me! Chris

Posted By mark pearson Hi Chris they had read an article (Daily Mail, I think) Daily mail that figures!!! Well organizational we make and market a wide range of antibacterial products and you can correlate sale volume to press coverage and the over hype that it all receives within the wider media our sales team regularly get customer requests for products just to make people feel more secure and safe! whether they make a real difference????? i think not but the customer is always right even when their wrong as the saying goes.

Posted By Alan Nicholls Chris Does the MSDS say anything about dilution if ingested, with say water. Think I would prefer Scotch. Or what reaction there might be should it come into contact with water. You've got to laugh. Sorry I thought it WAS Friday!! regards Alan

Posted By Chris Packham Alan "Ingestion: Rinse mouth thoroughly. Get medical attention." It also recommends that you should wash at the end of the shift and also that you should wash promptly if the skin becomes wet! It also mentions that this product is stable under normal temperature conditions. Oh, and you should dispose of wate and residues in accordance with local authority requirements. (Like, put it down the drain?) Chris

Posted By ScotsAM I find that most MSDS are generic nonsense with little useful information on them.
