The voluntary fire brigades (Bomberos Voluntarios del Peru) of Lima's districts and of some other cities in Peru respond to any kind of medical emergency quickly and provide an excellent service free of charge (a donation is more than appreciated and needed).
Their units are well-equipped and the first responders well-trained.
So, if you had an accident of any kind or any other medical emergency, but aren’t privately insured including a private ambulance service, call the bomberos for quick and reliable help and first aid.
