I wanted to add a Cable TV line to our other bedrooms by splitting the one in the Master Bedroom. We didnt want to see wires in the hallway so I wanted to do the splitting in the attic.

Anyways, when I got up there, I was a bit discouraged to find out how hard it is to move around and all the ceiling joists were covered with cellulose (R-30, 8" height). I've got a few questions for the experts out there.

1) Is it safe to disrupt the way the cellulose is laid?

2) I was planning on using a plank of wood so I can walk around. Do I have to clear out the cellulose so my plank of wood directly hits the ceiling joist?

3) Is it safe to leave my plank of woods up there?

4) Any other precaution I should take? I wear dust mask and goggles and I have 2 workshop lights w/ a 100ft extension cords.

5) Is it safe to split my cable line with a cable splitter screwed on the ceiling joist without an electrical box?

Can you do this from your basement or crawlspace? I like to add from below because if you leave enough slack you can move the cable around if you move furniture upstairs. You can drill a hole through the carpet and floor just big enough to fit the cable through. The hole will hardly be visible when you aren't using it. The carpet fills it in a little.

If you can't do that.
1. I can't answer 100%, but I would think it's OK to move the insulation so you can get to the cable. If it's loose insulation as opposed to paper backed then maybe take a rake up and move it out of the way with that. Do it slowly so you don't kick up dust if you are concerned with that.

2. You should be able to use your plank. The insulation will just compress until you hit the joists. I don't think you have enough insulation to worry about hurting the drywall by compressing the insulation that much.

3. It is safe to leave your planks up there, however you will be compressing your insulation limiting it's insulating value. If it were me I guess I would pick a spot and lean them on it's skinny side so you only lose a little insulating value.

4. Precautions you should take. I like to take a small toolbox with me that has anything I may need. Drill with bits, flashlight, etc.

5. I think it's safe to split the cable without an electric box. I've never seen that done before.

I have no professional experience in any of these fields these are just my opinions.

Good luck,
