Many smoke detector programs fail to ensure long-term protection, with a significant percentage of detectors non-functional due to missing batteries. Future programs need improved battery strategies for sustained residential fire safety.

Area of Science:

  • Public Health
  • Fire Safety Engineering
  • Injury Prevention

Background:

  • Residential fire deaths disproportionately occur in homes lacking working smoke detectors.
  • Smoke detector distribution programs aim to reduce fire fatalities but face challenges with installation and maintenance.
  • The long-term effectiveness of these programs is uncertain due to potential non-installation and battery issues.

Purpose of the Study:

  • To evaluate the long-term functional status of smoke detectors provided to high-risk households.
  • To assess the enduring impact of smoke detector promotion programs in preventing residential fire deaths.
  • To identify factors affecting the sustained effectiveness of distributed smoke detectors.

Main Methods:

  • A cross-sectional study design was employed.

  • Home visits were conducted 3 to 4 years after detector distribution.
  • Randomly selected households from three detector promotion programs were evaluated for the presence of at least one working smoke detector.

    • Main Results:

    • Household participation rates in the evaluation ranged from 72% to 82%.
    • The proportion of households with a working smoke detector varied, from 58% in Oklahoma to 73% in North Carolina.
    • In non-working detectors, 76% had missing or disconnected batteries; 83% were functional after battery replacement.

    Conclusions:

    • Future programs should prioritize smoke detectors with non-annual battery replacement or implement robust battery replacement strategies.
    • Ensuring adequate detector coverage per National Fire Protection Agency standards is crucial.
    • Unannounced home visits are a practical method for evaluating injury prevention programs in high-risk populations.
