Certified Fire Protection Specialist (CFPS) Practice Exam Prep

Smoke alarms in one- and two-family dwellings must be replaced after 10 years from the date of manufacture because the materials and components used in these devices can degrade over time. After a decade, smoke alarms may become less sensitive and more prone to failure, reducing their effectiveness in detecting smoke or fire. This guideline is established by various safety organizations, including the National Fire Protection Association (NFPA), to ensure that smoke alarms remain reliable and functional throughout their operational life. Regularly replacing smoke alarms is crucial for maintaining a safe living environment and ensuring that residents are protected from fire hazards.
