Hey Doug - as the person first posting the request for info let me tell you that I am short sighted. I suppose you think I should not wear glasses
We`re not all the same you know !!
From my perspective, anyone who cannot reach the isolater should consider another valid option - and a slob knob is a valid option.
In terms of overall risk assessment - any option that improves ones ability to deal with a situation is a good option in reducing what is a small risk if the kit is properly looked after and maintained
Thanks though - interesting to get others opinions
