Recent incident trends show wellsites and refineries need extra scrutiny

Incidents were attributed to a decade and supply chain segment based on a detailed analysis of over 200,000 records. This analysis excluded gas explosion events, so actual H2S-related incident counts may be higher than shown. Each segment-decade combination is color-coded into four likelihood tiers — Rare, Moderate, High, and Extreme — based on Fisher-Jenks natural breaks: Rare (<0.3), Moderate (0.3–1.4), High (1.4–2.4), Extreme (≥2.4).
