Morning all, Does anyone have any safety data on how much punishment a breaksafe bottle will take before its nasty chemical content will escape all over the floor? My organisation uses 70% Nitric Acid plus some unpleasant organic solvents that come in 2500ml glass bottles with a 'break safe' coating, and so I am keen to make sure that our control measures are right. Whilst it may not be as much fun as dropping such bottles (filled with water!) from various heights onto a concrete floor, it is probably easier to ask if anyone any information on what we could reasonably expect if a chemical bottle did get dropped. I appreciate the other control measures of elimination, seperation etc. Thanks.

We regularly demonstrate one being dropped onto a laboratory floor (not concrete) and it has survived very many such falls. The bottle is clearly broken, but the coating has retained all the fragments and I suspect it is still liquid-tight. However, the bottle is empty, and I am sure a full one would not fare so well. Nevertheless, it has to be better than a simple bottle; even if the contents did start to leak, it would be a great deal slower than a regular bottle.

They do leak (sometimes), though stay intact if dropped but I've not known of many occasions when bottles are dropped so the risk may be more apparent than real. Remember, many bottles may have already had a hard life when you get them; the container and its outer film may already be scuffed and damaged when you receive it. A carry frame is always preferred, to assist lifting and tipping (pouring), and to keep bottles from hitting each other or some other item when in transport, in use or in storage.

Thanks both, you have certainly confirmed my view that they are not indestructible but far better than than the standard glass bottles of old. I did spot Jane's previous post about finding acetic acid stored next to Nitric, fortunately my firm doesn't do that but does use both.
