If a call involved a fall of more than 6 feet it was designated a lower priority 'category B response' despite the presence of life-threatening conditions which were supposed to receive the most urgent category A response.
Even if other factors should have given the situation an A level, it would be B because the fall wasn't "high enough". That's the flaw in the system here, if I understand the article correctly.
