Project Details

Gyeongju, Gyeongsangbuk-do — Wandi GasTiger 2000 Multi-Gas Detector Delivery

This delivery supplied Wandi GasTiger 2000 multi-gas detectors to an industrial facility in Gyeongju, Gyeongsangbuk-do, supplied by MG Korea. The unit is configured to measure five gases simultaneously — CO₂, CO, O₂, H₂S, and EX (combustible) — and was introduced specifically to prevent industrial gas accidents, which remain a frequent and serious hazard in confined workplace environments. Prolonged inhalation of hazardous gases in enclosed spaces can cause severe health effects and, in the most serious cases, fatalities — making proactive prevention through reliable gas monitoring the highest priority.

Confined Space Five-Gas Hazard Characteristics

  • O₂ (Oxygen) — Below 18%: immediate evacuation. Above 23.5%: sharply elevated fire risk
  • CO (Carbon Monoxide) — Colorless and odorless. Generated by incomplete combustion. TWA below 25 ppm
  • H₂S (Hydrogen Sulfide) — Anaerobic organic decomposition product. TWA 1 ppm. Causes rapid loss of consciousness at elevated concentrations
  • EX (Combustible Gas) — Explosion risk above 10% LEL. Detects a range of combustible gases including methane and hydrogen
  • CO₂ (Carbon Dioxide) — Organic decomposition byproduct. Headache and respiratory distress above 1.5%

Gas Hazard Environments at Gyeongju Industrial Facilities

  • Factory underground tanks and pits — gas generation from inert gas handling and combustion equipment
  • Wastewater treatment facilities and septic tanks — H₂S, CH₄, and CO₂ from anaerobic decomposition
  • Construction site underground excavation areas — gas generation from soil organic decomposition
  • Warehouses and logistics facilities — forklift exhaust (CO) and refrigerant leak (CO₂) hazards

Frequently Asked Questions

Can GasTiger 2000 measure all five gases simultaneously?

GasTiger 2000 supports up to four sensor slots. For all five gases simultaneously, the GasTiger 6000 (up to six gases) model is the appropriate choice, or the four highest-priority gases for the specific site can be selected. The optimal configuration should be determined based on a site-specific hazard assessment.

What procedures are needed to prevent gas accidents at Gyeongju industrial facilities?

① Pre-entry gas concentration measurement inside the confined space using GasTiger 2000 before work begins; ② Confirmation that all five gases are within safe limits before entry; ③ Continuous monitoring with the detector carried throughout the work period; ④ Immediate evacuation if any alarm activates. These procedures are mandated under Korea's Occupational Safety and Health Standards confined space work requirements.

How portable is the GasTiger 2000?

Its compact, lightweight design allows it to be carried in one hand or clipped to a belt for mobile field measurement. The internal sampling pump allows safe pre-entry assessment of confined space interiors from outside — enabling a go/no-go decision before any personnel enter the hazardous space.

How can after-sales service and calibration be obtained for GasTiger 2000 in the Gyeongju region?

MG Korea provides after-sales service and calibration for industrial facilities throughout Gyeongsangbuk-do and the broader Yeongnam region. Scheduled calibration (every six to twelve months) is arranged by sending in the unit or by on-site service visit, with a calibration certificate issued upon completion.

How can secondary casualties be prevented during a gas accident response?

The most common cause of secondary fatalities is a co-worker entering without protective equipment to rescue a fallen colleague. GasTiger 2000 should be used to verify gas concentrations from outside first; if hazardous concentrations are confirmed, only designated rescue personnel wearing self-contained breathing apparatus (SCBA) should enter. Calling emergency services (119) simultaneously is the safest approach.
