Asbestos pipe insulation?

[Bobmonga]

I've just been under the floorboards of my 1930s semi and would like some advice on the old water mains insulation. I would like to make sure it's not asbestos. The first photo is a close up of a piece on the floor. The second is some of it still on the pipe.

Many thanks in advance.

Definite possibility. I'd leave it undisturbed although maybe damp it down and send a small piece for analysis.

I'd happily leave it alone, especially as I'm mildly claustrophobic! However, it's in the way of installing some insulation between the floor joists.
I've ordered a kit off Amazon. I'll let you know what they say.

Thanks - it'll be interesting to know

Looks more like horse hair plaster.

There appears to be a lot of [possibly] horse hair in that material.

As an aside if Asbestos fiber has to be viewed under a microscope.
