There are people who don't want to pay for a home sprinkler system, but it could still save their lives. By the NFPA, sprinkler systems in your home can cut your chances of dying in a house fire by 80% and the amount of damage done to your home by 97%. Smoke detectors are important, but they don't do much to stop a fire from getting out of hand. When there is a fire in your home, sprinklers will both alert you and give you and your family time to leave. They will also help contain the fire.
