Hi Antonija.......
I agree with Alan, i think you could use a better word than 'disturbance'.
Some better general alternatives I think you could use are; 'stoppage' , 'breakdown' or even 'interruption'.
But to fully answer your example I need to alter it somewhat with some minor additions. I hope this is what you had in mind. See what you think...
Due to an interruption in the process a dangerous situation was created when gas leaked, chemicals were spilt and dangerous leaks of scalding steam and hot water began. This led to an increased risk of fires, explosions and personal injury.
