Updated on December 18, 2020 at 10:45 pm Matt Rascon, NBC 7 San Diego County Fire is now offering qualifying residents a secure key safe called KnoxBox that will allow first responders to gain access to a home within seconds in a life-threatening or critical situation. “When someone is having a medical emergency and becomes pulseless and apneic, it’s really important for us to get in there and provide medical attention within 4-6 minutes and it’s costing us minutes to get in when we are having to break a door down,” said County Fire Deputy Chief Dave Nissen, who has worked in the rural East County communities for 30 years.
