Liuyang Explosion Highlights Safety Gaps: Technical Approach of Intelligent Explosion-Proof Storage Systems

Liuyang Explosion Highlights Safety Gaps: Technical Approach of Intelligent Explosion-Proof Storage Systems

Incident Background

A recent explosion in a fireworks manufacturing facility in Liuyang, China, resulted in significant casualties and losses.

The incident highlights key risks in hazardous material storage, including:

Temperature anomalies leading to thermal runaway

Accumulation of flammable gases

Delayed detection of smoke and early fire conditions

Insufficient emergency response mechanisms

Industry Requirement

Traditional storage methods rely on:

Manual inspection

Passive fire/explosion protection

Non-continuous monitoring

These approaches are insufficient for complex industrial environments.

The industry is shifting toward integrated monitoring–warning–response systems.

System Design

Taking Wuxi Super’s outdoor explosion-proof storage cabinet as an example:

Monitoring Parameters

Smoke detection: response time < 3 seconds

Gas detection: accuracy ≤ ±3% FS

Temperature and humidity monitoring

Response Logic
