How much weight can my building hold?

[TBONTB]

I've found a potential load bearing point, and have come up with a concern I'd like peoples opinion on. There are ceiling joists in a detached structure on my properTy. They are 2x8s or 2x10s. They span about 12 feet and appear to be roughly 4 feet apart. They are well situated to use as anchor points. My weight is 175 pounds.

So here is the question. Will I damage the structure if I hang from these for several hours post mortem? I can test these by hanging from one, and have done that very briefly..hanging with my hands. However it's just occurred to me that they need to hold up more than the time it takes to cvt, but in fact until I would be removed. Are there any engineers or good condo people who can comment on this?

Should have probably made the title more clear. It's about how much the anchor point can hold without damaging the building

Are they 2x8 or 2x10? 2x10s have significantly more strength
Anyways, over the course of a couple hours 180lb won't cause significant damage

I don't think it can be answered without knowing a few things about the wood (grade, wood species, general joist condition)

The wood is old growth Douglas fir. Condition of joist looks fine at a glance. I'll try to measure later.
