I am going with no. If you had the fuse in your pocket or van then yes.
Although theres nothing to stop someone from pulling another fuse and energising the circuit you are working on i suppose.

And I was working in the hallway directly outside the cupboard!
 
Changed that for you.

I have (read, had) a pair of sidecutters that would disagree with your original quote. I once let myself be cajoled into using a voltstick mid cable on a job that was not my own. One of the very few times I have neglected to safely isolate, but one of the biggest reminders. Also the first time I ever used a voltstick, and one has not been in my hand since.

I'd agree that they're not the most reliable of instruments. I always check that they're functional before and after use, preferably on a live cable if not, then by the static on my clothes!
 
Safe isolation of a 3036 would require the use of a blanking module after removal of the fuse carrier as you are potentially leaving exposed live parts, as safe isolation is prevent electric shock to anyone not just the person working on the circuit. This would also prevent accidental replacement of a fuse. So in answer to Murdochs question no it isn't safely isolaoted

With those it is always best to remove the cable for that reason.

As others have said in a domestic it is a bit of common sense applied , but if other trades, kids etc, you have to make it so that you are the only one who can get the power back on by whatever means work for you.

Industrial is a different ball game as Rob has said.
Circumstances dictate events

It worked before, it worked after, it still threw me a curveball. You are damn right they are not the most reliable of instruments, or use any reliable method to function.

It may not be 'safely isolated', but would you do it (given the circumstances outlined by Murdoch)?

I see the point about being able to replace a fuse into the slot.
Is not the barrier requirement for both live parts and the front of an enclosure IP2X ? This would be afforded by the fuse base surely, therefore not leaving exposed live parts ?
