## Project Background
The steel plant under this group, with an annual production capacity of 8 million tons, operates with a combination of converter gas and coke oven gas, posing a high risk of CO poisoning. The original monitoring points have aged and are not fully covered, leading to multiple incidents of operators being exposed at close range.

## Implementation Plan
Deploy 120 sets of Panshi YQ-CO high-tolerance fixed detectors to cover the front of the converter, charging layer, and gas cabinet area. Each frontline worker is equipped with a whistle-type portable four-in-one detector. The data is integrated into the workshop DCS system and linked with smoke exhaust, broadcasting, and access control systems.

– High-temperature (≤80°C) dust-proof and corrosion-resistant housing, extending the sensor lifespan to 36 months
– Three-level threshold of 30/100/300ppm, automatically initiating gradient response
– Fixed inspection robots are supplemented with mobile CO probes

## Implementation Effect
After being deployed for 12 months, there have been no CO poisoning incidents, and the average response time for over-limit alarms in critical operation areas has been shortened to within 90 seconds. The group has approved the replication and deployment in two other steel mills.
