Composite verdict
Composite Safety Score: 33/100
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.
| Dimension | Value | National percentile | Weight applied | Source |
|---|---|---|---|---|
| Injury severity (hospitalization + fatality blend) | 6 | 53rd | 35% | CPSC NEISS 20-year severity index |
| Annual ER injury volume | 89 | 7th | 30% | CPSC NEISS estimated annual ER-treated injuries |
| 5-year injury trend | +27% | 85th | 15% | CPSC NEISS 5-year % change in ER-treated injuries |
| Consumer incident reports | 0 | 0th | 20% | CPSC SaferProducts.gov public incident report count |
Methodology: each dimension is ranked against the full population's p10/p25/p50/p75/p90 breakpoints and interpolated to a 0-100 percentile; the composite is the weighted average of available percentiles. See methodology for the full benchmark table.

How this 29/100 score is built
The score is computed from four CPSC-derived factors for lightning rods, arresters or other grounding devices - no opinion, no editorializing:
- Injury volume 89 ER visits/yr Low volume
- Severity (hospitalization rate) 6.3% Above median admission rate
- Fatality rate 0.00% No recorded fatalities
- 5-year trend+27%
Band labels compare this category against the corpus of 838 scored CPSC product categories, see the full methodology for the exact weighting of each factor.
What the CPSC Data Shows
Across the 20-year NEISS window from 2005 to 2024, injury counts for lightning rods, arresters or other grounding devices are rising by about 27% over the last five years, with the busiest year on record being 2010 (211 estimated ER visits) and the quietest 2008 (15 estimated visits). The single most common ER diagnosis is laceration to the lower arm, accounting for approximately 152 visits across the 20-year NEISS window, followed by laceration to the head (151 cases). The 25-34 age group absorbs the largest share of injuries, about 335 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 6.3% of ER visits involving this product end in hospital admission or transfer.
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 lightning rods, arresters or other grounding devices 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.
