Serious Accidents Punishment Act Asphyxiation Prevention — EDW500 Five-Gas Portable Multi-Gas Detector
This case introduces the EDW500 portable multi-gas detector — equipment that should always be carried to prevent confined space asphyxiation incidents, among the most serious workplace accidents addressed under Korea's Serious Accidents Punishment Act.

Five EDW500 five-gas detectors were delivered for use during confined space work at a sewage utility office, intended to be carried by workers throughout entry and operations. Delivery of the five units included KOLAS calibration and testing certificates for all five gas channels.

Before delivery, the detectors underwent a final inspection. The EDW500 multi-gas detector supports the full set of functions required under the revised legislation.
Delivery Specifications

Multiple supervisors can log in to the cloud platform at the same time to check EDW500 gas concentration readings in real time.

Why Confined Space Asphyxiation Is a Critical Risk
Confined space asphyxiation incidents occur less frequently than some other types of serious workplace accidents, but once they occur, they carry the highest fatality rate of any safety incident.
Gas concentration must always be measured before entering or beginning work in a confined space, and adequate air quality and ventilation must be maintained throughout.

Additional KOLAS Calibration Services
In addition to these five gases, KOLAS calibration certificates can also be arranged for a range of other gases, including volatile organic compounds (VOCs), hydrogen, ammonia, ozone, and chlorine, with fast turnaround times.

End-to-End Service Process
The full process — detector selection, ordering, KOLAS certificate issuance, on-site delivery and training, and ongoing maintenance — can be handled as a single service.
Why EDW500 Is Essential for Serious Accidents Punishment Act Compliance
- The Act imposes direct criminal liability on company executives for confined space fatalities, making portable five-gas monitoring a fundamental compliance measure
- Sewage utility offices manage facilities classified as confined spaces under Korea's Occupational Safety and Health Standards
- Each worker entering a confined space should carry an individual detector for continuous personal monitoring throughout the work period
- Five units delivered to enable simultaneous deployment across a work team or multiple entry points
EDW500 Certification and Compliance Highlights
The EDW500 measures all five gases required for confined space work — O₂, CO, H₂S, CO₂, and LEL (combustible gas) — in a single unit. It holds dual IECEx and ATEX explosion-proof certification, and its free DCMS cloud platform with automatic email reporting helps satisfy the Occupational Safety and Health Act's 3-year data retention requirement. KOLAS calibration and testing certificates are also available.

Frequently Asked Questions
Why is a portable detector necessary in addition to any fixed monitoring at the sewage utility?
Fixed detectors monitor specific installation points continuously, but a worn portable detector provides personal, real-time monitoring as the worker moves through the confined space, accounting for localized gas concentration variations that a single fixed point might not capture.
How does the EDW500 support Serious Accidents Punishment Act compliance?
The Act holds executives criminally liable for confined space fatalities. Equipping workers with portable five-gas detectors for every confined space entry is a foundational and demonstrable safety measure supporting legal compliance.
Why were five units delivered to this sewage utility office?
Delivering multiple units enables simultaneous use across a work team, ensuring every worker entering a confined space has individual access to a detector rather than sharing a single unit.
What does the process look like when procuring EDW500 detectors for a similar application?
The typical process includes detector selection, ordering, KOLAS calibration certificate issuance, on-site delivery with training, and ongoing maintenance support.
