CLEAN : At least 43 killed in Delhi factory fire

The video transcript begins with an initial discussion that seems disjointed and abstract, possibly setting up a scenario. It then transitions into a detailed account of a rescue operation where rescuers enter a room with SCBA and check for hazardous gases. They find no hazardous gases but note elevated carbon monoxide levels due to the room being closed. Another team follows to conduct search and rescue operations.

What was the condition of the room that affected the air quality?

What did the other team do after the first rescuers completed their checks?
