On the last day before Yamagami leaves Fuwa Rescue, there is a special order dispatch for them to go to a printing facility that has caught on fire. Inside the building, there are powders that could cause a dust explosion.
If that powder becomes 
airborne and ignites...
...إن طفا ذلك المسحوق في الهواء واشتعل
Si ese polvo se mueve y se incendia…
Si ese polvo se mueve y se incendia…
Se la polvere rimane sospesa nell'aria e brucia...
Se o material particulado se
dispersar no ar e entrar em ignição...
Если порошок разлетится
по зданию и загорится…
