Which burn requires 911?

Could you elaborate on the context of the phrase "Which burn requires 911?"? It seems to be a somewhat unusual or cryptic question, as "911" is typically associated with emergency services in many countries. Are you referring to a specific type of burn injury that would necessitate an immediate call to emergency services? Or is this a metaphorical question, perhaps relating to a situation where a "burn" in the sense of a financial or emotional loss requires immediate attention or intervention? Clarification would be helpful in providing an accurate and relevant response.
