Composite verdict

Composite Safety Score: 49/100

One verdict blending 4 independently-sourced dimensions from two separate CPSC systems, each benchmarked against all 838 scored product categories by percentile rather than raw value, so no single huge-volume category can dominate the scale.

How this 38/100 score is built

The score is computed from four CPSC-derived factors for carbon monoxide poisoning (when source is unknown - no opinion, no editorializing:

  • Injury volume 7,498 ER visits/yr Above median volume
  • Severity (hospitalization rate) 7.7% Above median admission rate
  • Fatality rate 0.18% Elevated fatality rate
  • 5-year trend-32%

What the CPSC Data Shows

Across the 20-year NEISS window from 2005 to 2024, injury counts for carbon monoxide poisoning (when source is unknown are declining by about 32% over the last five years, with the busiest year on record being 2011 (12,614 estimated ER visits) and the quietest 2020 (3,731 estimated visits). The single most common ER diagnosis is anoxia to the all parts body, accounting for approximately 147,312 visits across the 20-year NEISS window, followed by poisoning to the all parts body (1,334 cases). The 5-14 age group absorbs the largest share of injuries, about 25,917 cases over the NEISS window, and females appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 7.7% of ER visits involving this product end in hospital admission or transfer, and a small fraction (0.18%) result in fatality.

Beyond the hospital-sampled NEISS projections, this page also aggregates 0 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how carbon monoxide poisoning (when source is unknown fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.
