Olympic Waterguard wood sealer on new coop, but it's also on the run/grass, toxicity concern?

[Somyis]

My uncle sprayed this sealer on the inside/outside of our new 4x8 walk in coop (that we're going to paint over as well) but he did it in the backyard where our chickens/dogs run about- do we need to worry about the grass getting ingested even after dried? It definitely got on the grass good because all of the bottom was sprayed too, which just a few inches up from the ground. And because he also sprayed down a couple new run ladder perches that are directly laying on the grass heh

Thanks

After it fully cures, it should be benign.
