Inhaling vapor while observing Sawm

Q: I work in the General Corporation for Water Desalination. We observe Sawm (Fast) during Ramadan while we are working, (Part No. 10; Page No. 276) but we are surrounded by steam in the plant where we work. As we often inhale the steam, does this affect the validity of our Sawm? Are we supposed to make up for the days in which we have inhaled the steam while observing Sawm (whether as an obligatory or supererogatory act of worship)? Are we required to pay Sadaqah (voluntary charity) for every day of inhaling steam at work while observing Sawm?

A: If the matter is as you mentioned, then your Sawm is valid and you are not required to make up for these days.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
