There are around 40,000 firefighters in Chile and they all work for free. The only people in the service who are paid are the drivers, messengers and secretaries who work in the fire stations.
When a fire breaks out, when there is a car crash or when an earthquake strikes, volunteers leave their day jobs as lawyers, shopkeepers and bankers and head to their stations to help out. Many work night shifts and weekends for free.
Indeed, Chilean firefighters have to pay to be part of the force. They all make monthly contributions to their stations.
