Hello, this is RS Korea ZOE. The place we visited for this installation was the sewage treatment plant within the national hospital in Gangwon-do.

■ What is a sewage treatment plant? It is a facility that collects dirty water (water that is used in various daily lives and can no longer be used), treats it cleanly, and discharges it into rivers or the sea. ■ Purpose of installation

The Occupational Safety and Health Act applies to all sites. As the law was revised in 2017, it was legislated that confined spaces are places where there is a risk of suffocation, fire, explosion, etc., and carbon dioxide (CO2) must be added to the existing four major gases (O2, CO, H2S, LEL) to measure a total of five gases. In particular, since gas concentration must be measured during work in environments where harmful gases may be generated, gas meters must be installed inside confined spaces and entrances and exits are required. A gas status board must be installed outside so that the internal situation can be ascertained. The place visited for this installation was a sewage treatment plant located within a national hospital. Sewage and sewage treatment plants are environments where 'hydrogen sulfide' is generated. The odor is strong, and the amount of hydrogen sulfide generated rapidly increases when sediments such as sedimentation ponds and storage tanks are stirred. Inside the sewage treatment plant, which is a closed space, the purpose is to ensure the safety of workers. Installation was carried out as a measuring instrument for the five major gases (required measurement gases under the Occupational Safety and Health Act) was required.※ For more information on hydrogen sulfide, please check the URL below. https://blog.naver.com/rs-korea1/222923428300■ Installed products

FIX800 is an installation-type gas detector that can measure up to five gases with one product. The gas detector is installed inside where the gas is generated, and the gas concentration status board is installed so that the internal situation can be checked from the outside.

Installation example 1) 5Gas [o2, co, h2s, lel, co2] meter for septic tank safety, warning light, gas concentration status board

Installation example 2) Comprehensive disaster prevention room, equipment base, computer room, fire extinguishing agent room, electrical room FIX800 oxygen concentration meter [o2], warning light, gas concentration status board

Installation example 3) Fire extinguishing agent oxygen concentration meter [o2], warning light, gas concentration status board■ Installation equipment

These are the items required for this installation. There is an installation-type gas meter FIX800, a gas concentration status board, and an acrylic box made for waterproof purposes as it is an outdoor installation. Unlike existing installation cases, there are additional items added to the equipment. The gas concentration status board is a waterproof product that is manufactured for basic outdoor use. However, during the on-site inspection, the person in charge requested that we make a cover so that the electronic display board would not be completely exposed, so we made it. At RS Korea, we take into account the site environment and situation, understand the direction desired by users who actually use the product, and also process custom orders accordingly.■ Installation points

This is inside the sewage treatment plant. This is the installation point for the installation-type gas meter FIX800.

■ Installation

First, position the bracket and secure the product to install the gas meter.

Although the sewage treatment plant is an enclosed space, it is built as a container building on the ground, so installation work was carried out with continuous ventilation during installation.

This is the outside of the sewage treatment plant. A gas concentration status board is being installed on the left side of the entrance. Because it was necessary to connect the internal electronic signboard and power, drilling was done in the wall. Because it was a container building, there was no difficulty in drilling into the wall.

Preliminary work is underway to install the acrylic box requested by the person in charge.

The manufactured acrylic box has a perforation at the bottom to prevent moisture.

Installation of the manufactured acrylic box has also been completed.

Although the gas concentration is not high enough to cause health problems when exposed for a short period of time, I thought that this was a site that should not be easily overlooked, considering that low concentrations of harmful gases were continuously inhaled when the windows were closed to create an enclosed space and working hours were long. Rather than just thinking, ‘The law says I have to measure it,’ I thought it was essential to install a gas meter and manage its values for the safety of workers. The installation work was completed after test driving, product information, and training to the person in charge. In closed spaces, air circulation is poor and the space is blocked from the outside, causing suffocation when harmful gases leak or oxygen concentration decreases. In environments where bad odors occur, such as sewage treatment plants, it is mandatory to install a gas concentration meter and place a status board outside to ensure workplace safety. In this case, a measuring instrument was installed inside the tunnel and a gas concentration status board was installed outside. This ensures the safety of workers by allowing them to check the internal situation from outside before or during work. In addition to simple product sales, RS Korea is a gas-specialized company that provides self-calibration/domestic repair (A/S)/production/delivery/installation work. We provide 1:1 customized solutions for gas measurement environments based on our experience conducting demonstration / inspection / delivery / repair / installation work in various environments.
