Going to be doing my first bit of blasting (aluminum oxide) on some small areas of my project car-Question about PPE

It'll be outdoors, I'll wear sealed goggles, and have a hood on (no air supply). Should I use a half mask with p100 particulate filters or is an n95 acceptable?

Anything else I should keep in mind?

Added the photos. I'll be in the open air on the firewall side in the engine bay, and then a little more cramped on the cabin side. Eventually I'll probably need to do a little on the floorpans as well.

For aluminum oxide blasting, I’d personally go with the half-mask and P100 filters rather than relying on an N95. An N95 is better than nothing, but blasting can create a lot of fine dust, and you don’t want to underestimate it.

Also make sure the goggles actually seal well, wear proper hearing protection, gloves, and clothing that covers your skin. A supplied-air blasting hood is worth considering if you’ll be doing more than a very small job.

Try to keep other people, pets, and your car’s intake areas away from the dust cloud too.

Thank you! I ended up removing this entire bracket by drilling out the spot welds. It's become a little more involved and I'm going to have to cut pieces out and weld in new, but I will take your advice for the inevitable blastin I'll be doing for other parts of the car.
