Why You Need a Fixed HCl Detector
Hydrogen chloride (HCl) is a corrosive, toxic gas continuously generated at industrial sites such as semiconductor etching, electroplating, and chemical processes. Its permissible limit is a very strict ceiling value (C) of 5 ppm, and it is generated continuously even at night when workers have left the site, or while the process is running. The FIX800 fixed detector instantly detects HCl leaks at any time through 24-hour continuous monitoring.
💡 Key Advantage of the Fixed FIX800
Semiconductor and plating plants often run processes 24 hours a day. The FIX800 instantly detects HCl leaks even during unmanned processes, and managers can check in real time remotely via the FIX-DS display board and web monitoring.
HCl Health Effects Table
| Exposure Concentration | Exposure Time | Health Effect |
|---|---|---|
| 1~5 ppm | Short-term | Eye/nose/throat irritation, coughing |
| 5 ppm (C) | Ceiling value | Korea exposure limit — evacuate immediately if exceeded |
| 10~50 ppm | Minutes | Airway mucous damage, pulmonary edema |
| 50~100 ppm | Short-term | Airway edema, respiratory failure |
| 1000 ppm | Immediately | IDLH — immediate threat to life |

Real Accident Cases
🇰🇷 HCl Leak at a Domestic Plating Plant (2020)
In 2020, at a plating plant in Incheon, HCl leaked due to pipe corrosion during a nighttime process. Two night-shift workers were treated for respiratory burns, and the absence of a fixed detector was identified as a cause of the accident's escalation.

🇩🇪 HCl Leak at a German Chemical Plant (2017)
At a chemical plant in Ludwigshafen, Germany, an HCl pipe rupture spread gas to the surrounding area, forcing dozens of residents to evacuate. Analysis concluded that an early-detection system would have allowed a rapid shutoff. (Source: DGUV Unfallberichte, 2017)
WANDI FIX800: HCl Continuous Monitoring Solution
FIX800 Key Features (HCl Measurement)
- Simultaneous detection of up to 5 gases: HCl, O₂, CO, H₂S, EX monitored together
- HCl electrochemical sensor: measures 0.5~50 ppm, alarm configurable below 5 ppm (C)
- 24-hour continuous operation: automatic alarm during night, weekend, and unmanned processes
- FIX-DS display board integration: real-time concentration shown outside the process room
- Web monitoring: remote real-time monitoring and history management via PC/smartphone
FIX800 Prevention Scenario: Nighttime Plating Plant
- 1During the nighttime process: HCl slowly begins to leak from pipe corrosion
- 2FIX800 detects exceedance of 5 ppm: immediate audible/visual alarm, high-concentration display on the FIX-DS board
- 3Web monitoring alert: instant alarm sent to the on-call night manager's smartphone
- 4Emergency process shutoff: stop the HCl-generating process via remote control or on-site response
- 5History logging: the full concentration-change history is recorded automatically, used for root-cause analysis
