Industry Background

The petrochemical industry is a key pillar of the national economy, involving large quantities of flammable and explosive chemicals in its production process, which is both complex and equipment-intensive. A fire can lead to significant personnel casualties, property damage, and potentially secondary disasters such as environmental pollution, severely impacting the social economy and public life. With the industry's growth, the demand for fire safety has become increasingly stringent, and efficient, reliable firefighting solutions have become a critical safeguard for safe production in petrochemical enterprises.  

Major Fire Risks in the Petrochemical Industry

• Flammable, Explosive Material and Leakage Risks: Crude oil, refined oil, and chemical raw materials produced in the petrochemical industry have low flashpoints and strong explosiveness. During storage, transportation, and production, leaks can easily occur due to equipment aging, poor seals, or operational errors.

• Process Equipment Leakage and Explosion Hazards: Long-term operation of pipelines, valves, reactors, and other complex process devices may lead to leaks caused by aging or corrosion. The leaked substances can form explosive mixtures when combined with air, and explosions can occur when exposed to fire sources.

• High Temperature and High Pressure Equipment Failures: Production processes are often carried out at high temperatures and pressures. Reactors, distillation towers, and other equipment can fail due to corrosion or fatigue. When equipment ruptures, high-temperature, high-pressure materials may be ejected and ignited, potentially causing chain reactions.

• Improper Parameter Control Risks: Strict temperature and pressure requirements are critical for production reactions. Loss of control can lead to violent reactions, material decomposition, gasification, or even explosions.

• Electrical Equipment Hazards: With numerous electrical devices in hazardous environments, sparks, overheating, and other electrical faults can trigger ignition. Electrical insulation is also prone to aging in corrosive environments, increasing the risk of short circuits and fires. For instance, one petrochemical company suffered a fire due to aging electrical insulation leading to a short circuit, igniting flammable gases.

• Human Error: Operational errors, such as working in fire-ban zones or improper material handling, can easily lead to fires.
