Industrial Safety Gas Measurement Equipment for Confined Spaces — Five-Gas (O₂/CO/H₂S/EX/CO₂) Configuration (Anyang, Gyeonggi-do)

Industrial Safety Gas Measurement Equipment for Confined Spaces — Five-Gas Configuration

This article covers confined-space gas measurement equipment compliant with Korea's industrial safety regulations. Possessing gas measurement equipment to prevent workplace gas poisoning incidents is mandatory — not optional — for compliance with the Serious Accidents Punishment Act and the Occupational Safety and Health Act.

Work in manufacturing facilities and confined spaces carries the risk of asphyxiation from inert and toxic gases.

GasTiger 2000 — Five Gases Simultaneously

The GasTiger 2000 measures five gases simultaneously:

O₂ (oxygen), CO (carbon monoxide), H₂S (hydrogen sulfide), Ex (flammable gas), CO₂ (carbon dioxide)

A powerful built-in pump enables pre-entry sampling through a hose into manholes and vessels before any worker enters.

Four-Gas vs Five-Gas — What Is the Difference?

Confined-space safety equipment is available in two configurations: four-gas or five-gas.

★ The difference is whether CO₂ (carbon dioxide) is included. ★ CO₂ is colorless and odorless but must be monitored as an asphyxiant in any environment where it may accumulate.

Pre-Delivery Inspection and Span Gas Testing

Thorough pre-delivery inspection is carried out to ensure every unit reaches the customer in full working order.

Span gas verification for measurement repeatability and accuracy is mandatory before every delivery.

Fixed Detectors and Integrated Monitoring Solutions

In addition to portable instruments, fixed-point gas detectors are also supplied, along with integrated monitoring solutions covering a wide range of gases and applications.

Fixed installations can cover inert-gas monitoring with full on-site installation services.

Frequently Asked Questions

Q1. Is gas detector ownership mandatory under the Serious Accidents Punishment Act and OSHA?

Yes. Korea's OSHA Article 618 and related regulations require gas concentration measurement before and during confined-space work. The Serious Accidents Punishment Act further mandates that employers establish a safety and health management system — failure to possess required monitoring equipment may result in legal penalties.

Q2. How do I choose between a four-gas and five-gas configuration?

A five-gas configuration (including CO₂) is needed wherever CO₂ may accumulate — dry ice storage, fermentation processes, CO₂ fire suppression rooms, and similar environments. For general confined-space work involving only toxic gas and oxygen-deficiency risks, the standard four-gas set (O₂, CO, H₂S, LEL) is sufficient. Consulting a specialist based on site conditions is recommended.

Q3. What is pre-entry hose sampling?

Before any worker enters a manhole or confined space, a hose connected to the instrument's internal pump is inserted through the opening to draw air from inside and measure gas concentrations. This confirms whether oxygen deficiency or toxic gases are present before physical entry — a critical preventive step.

Q4. How often should span gas testing be performed?

Periodic calibration is typically carried out every 6 to 12 months. Response verification with span gas is also required after sensor replacement, following extended storage, and is recommended the day before any critical confined-space entry operation.

Q5. Why operate both portable and fixed gas detectors together?

Fixed detectors such as the FIX800 provide continuous 24-hour monitoring at a specific location. Portable instruments like the GasTiger 2000 allow workers to conduct spot checks across multiple points as they move through a site. Combining both types provides complete coverage — fixed continuous monitoring plus mobile inspection — for the most comprehensive safety environment.
