Importance of Gas Detection for Confined Spaces

What is a confined space?

Confined spaces are defined as environments that are either fully or partially enclosed, relatively isolated from the outside world, and difficult to access. These spaces typically have narrow entry and exit points, are not well-ventilated, and can accumulate toxic, harmful, flammable, or explosive materials, or may have insufficient oxygen levels, making them hazardous for workers who remain inside for extended periods.

Common Types of Confined Spaces:

• Underground Confined Spaces

Examples include basements, underground warehouses, underground engineering sections, trenches, tunnels, drainage ditches, pits, waste wells, cellars, inspection chambers, biogas pools, and septic tanks.

• Above-ground Confined Spaces

Common spaces include distillation tanks, fermentation tanks, pickling tanks, pulp tanks, granaries, and material storage bins.

• Enclosed Equipment

This category covers ship holds, storage tanks, tank trucks, reaction vessels, kilns, flues, pipelines, and boilers.

The risks associated with confined spaces are significant due to the likelihood of hazardous gas accumulation, such as hydrogen sulfide, nitrogen dioxide, methane, and ammonia. If safety measures or operational procedures are not properly followed, workers can face severe incidents, including poisoning, suffocation, or explosions.

How to effectively prevent such accidents in confined spaces?

The Role of Portable Gas Detectors:

Portable gas detection instruments have become essential in mitigating risks within confined spaces. It is imperative to conduct air quality tests in work areas prior to any operations to ensure that conditions meet safety standards. This proactive measure can significantly reduce risks and protect workers.

Nanjing AIYI Technologies: Leading the Way in Safety

For over 16 years, Nanjing AIYI Technologies has been at the forefront of technological innovation, dedicated to enhancing workplace safety and actively responding to national policies.

To effectively decrease the occurrence of confined space accidents, we have introduced the AGH5200, AGH6100, and AGH6200 series of portable gas detectors. The AGH6200 model is a standard 4-in-1 gas detection alarm device capable of simultaneously measuring the concentrations of combustible gases, oxygen, carbon monoxide, and hydrogen sulfide. It provides automatic audio, visual, and vibration alarms when concentrations exceed safety limits.

In addition, we have designed a handheld gas sampling pump, the AGH1000B, specifically for confined space applications. This device complements the portable gas detectors for efficient sampling and is designed with intrinsic safety for use in explosive hazard areas, featuring a high-capacity battery for extended operation on-site.

Conclusion

When performing work in confined spaces, companies must prepare emergency plans, enhance training, and implement strict prevention measures to avoid accidents. We, AIYI Technologies, adhere to high standards and continuously improves its core research and development capabilities to establish itself as a leading brand in the gas detection and analysis sector.

We are committed to providing safe and reliable products for our customers!
