Industrial Dust Explosion Risk Monitoring

Problems at the site

A dust explosion happens when combustible dust becomes airborne, mixes with oxygen, and is ignited by a spark or hot surface.

This type of explosion can occur in environments such as shot blasting, grinding, or material handling processes, where dust is continuously generated.

A foundry faced a serious safety challenge during its shot blasting process.

Fine magnesium dust was generated inside the blasting booth, and if dispersed in the air, it could lead to a dust explosion.

While dust collection equipment was used as a countermeasure, a failure of the collector could immediately result in dangerous dust accumulation.

For this reason, real-time dust concentration measurement inside the booth was essential to maintain safe working conditions.

Solved by the Air Dust Monitor

Air Dust Monitor is a portable device that integrates a triboelectric dust sensor and continuously measures airborne particulate concentration around the device.

By placing the Air Dust Monitor at the work site, dust concentration inside the enclosed area can be continuously monitored, allowing early detection of abnormal dust levels and assessment of dust explosion risk.

The lightweight and handle-equipped design allows instant measurement, and quick installation without duct work or complicated setup.

Provides continuous monitoring in place of human observation.

Useful for maintaining safe workplaces and clean production lines.

Capable of operating in high-concentration dust environments (g/m³) such as mining area, bulk handling facilities, etc. which are difficult to measure with conventional dust monitors (mg/m³).

Achieved by the technology

Air Dust Monitor continuously measures airborne dust concentration inside the blasting booth. This enables early detection of abnormal dust accumulation and helps prevent hazardous conditions that may lead to a dust explosion.

If the dust collector fails or its performance decreases, dust levels can rise rapidly. Real-time monitoring provides a quick warning of such malfunctions, allowing operators to take prompt corrective action before the risk escalates.

By continuously monitoring dust concentration, the facility can maintain stable and safe shot blasting operations. This reduces unplanned shutdowns, supports compliance with safety requirements, and improves overall risk management in combustible dust environments.
