Common ignition sources include malfunctioning equipment releasing hot surfaces, electrical sparks from damaged wiring, and even static electricity generated during the transfer of flammable liquids. Phase Key Characteristics Primary Risks Initial Fire Ignition of released flammable material Flash fire, rapid flame spread Escalation Thermal radiation igniting nearby units Domino effect, multiple unit involvement Critical Event Overpressure vessel failure Explosion, BLEVE, fragmentation Late Stage Depletion of fuel or intervention Smoldering, toxic runoff, re-ignition Advanced Suppression and Emergency Response Due to the scale and complexity of these facilities, emergency response goes far beyond standard firefighting techniques.
Common Ignition Sources in Crude Oil Refineries
Strategic Cooling and Isolation. The Domino Effect and Secondary Hazards Unlike a contained structure fire, an oil refinery fire often triggers a chain reaction known as the domino effect.
Equipment Failure and Corrosion Over time, the harsh conditions within a refinery—including high temperatures, corrosive chemicals, and constant thermal cycling—degrade equipment integrity. Leaks are a primary concern, allowing hydrocarbons to mix with air and form explosive atmospheres.

Pipelines, heat exchangers, and pressure vessels can develop weaknesses, leading to catastrophic failures. The release of toxic gases, such as hydrogen sulfide or volatile organic compounds, adds a dangerous chemical hazard to the already chaotic thermal and physical events, complicating evacuation and suppression efforts.
