I want to make a dropper bottle now; can its wall thickness withstand vacuum?

I used to study Process Equipment and Control Engineering, but now I work in the fine chemicals industry; as a result, my design skills have deteriorated, and I can only rely on old reactor designs for reference. The design pressure is -0.09 MPa, the operating pressure is -0.08 MPa, the temperature is at room temperature, and the medium is a flammable and explosive liquid. The dimensions are φ1600*2000*8, with the upper and lower elliptical end caps also having a thickness of 8 mm. 2000 refers to the cylinder, made of 304 material – is that okay?
There’s no problem if the corrosion allowance is zero.
Vacuuming isn’t necessarily the solution~ It’s better to use a thicker material; for pressure vessels that are flammable and explosive, having a thicker wall doesn’t cost much more~ Safety is important
What does corrosion allowance refer to? How to understand it?
Once the design pressure is determined, there should be a safety relief device. We don’t need to consider overpressure situations, right?
Do negative pressure devices also have safety accessories?
