Emergencies are matched against the caller's own words by fixed rules — never
left to an AI's judgement — and the safety script is spoken word for word,

gas
“Smells like gas in the utility room” is enough. The caller is told to
leave the building, call 911 or the gas utility from outside, and not to

carbon monoxide
“The CO detector is sounding” — said the way people actually say it — gets
everyone sent outside into fresh air and told to call 911, and your team
is alerted straight away.
Always urgent, same as gas.
fire/smoke
A furnace smoking, smoke pouring from a closet, flames behind the furnace
door: the caller is told to leave the building and call 911, and your team
is alerted straight away.
A bare “burning smell when the heat first comes on” stays a routine call —
that is dust burn-off, not a page at 6am.

A sparking or arcing outdoor unit, a hot or buzzing panel: the caller is
told not to touch it and to switch the main breaker off if they can reach
