is it safe to put in or what?

the wood is oak from a company called noblehouse.

3/4 in. X3 1/2 in.

color oak gunstock

any info would help

thanks in advance

Well, you are probably ok if you are planning on intalling the floor in the garage. Joking aside, you should have the floor in the same space as it is going to be installed in for a period of time (undeterminable, it is an issue of individual site and product conditions) to acclimate.
The product you are describing is most likely Russian white oak, milled and finished in China. Measure the thickness, it is most likely 5/8th inch rather than 3/4. Not really a big deal if it is properly milled and dried.
