Friends, thanks for the answers. "you can try to make them ineffective" - yea, that's exactly what I did, but the effect is insignificant. I'll try the idea with an engineer. I was just sure that this was provided by the mod.
"water containers are a lot more efficient than gas containers, so carrying oxygen and hydrogen and using them to make water is not the best idea. better to just carry water" - There was a water shortage for 7 days. Thought it would be a good idea to produce it rather than dump it (kerbonism's style).
