200mW Red Fat Beam Laser Curtain Safety?

Hi there,

I'm an artist that creates abstract light installations, I've recently been commissioned to create a piece that I wanted to use lasers for.

I wanted a system of laser point lights that I could control from my console to creat grids,objects and patterns within 3D space.
I've seen these products used in many artworks and concerts before.
After doing a lot of research I came across this lot of 32 fat beam lasers which I could control individually by DMX.

I didn't realize until after they arrived yesterday and I had been programming them for sometime that they 3B laser rating and were as powerful as 200mW per unit.

Obviously these will be going nowhere directly near anyone's eyes, but I'm wanted some advice wether looking at the dots within a white walled gallery space would be in any way dangerous, even for preloaded periods.
Or whether the "fat beam" diffusion makes them a lot safer.

There are many of these fat beam laser rain units that use 200mW or high that are designed to be use above dances floors, such as this.

Where I would image direct eye contact would easily be possible.

Thanks
