Question

The following sentence might appear (although we hope not) as a safety instruction poster in a laboratory. Rewrite it, using proper General 1.
In the event of a conflagration too intense to be immediately extinguished, occupants of this locale are instructed to progress toward the most adjacent means of egress.

Answer 1

I don't know what proper General 1 is, but I'd rewrite this as:

"In the event of a fire that cannot be extinguished immediately, please leave through the nearest exit"
