Oxygen measurements are important to determine air quality, especially in confined spaces. In these measurements, the definition of closed area refers to the areas that are not designed for continuous operation and have limited entrances and exits. In indoor activities, employee influences and deaths are usually caused by unfavorable weather conditions. For this reason, it is necessary to measure the weather conditions in confined spaces very precisely and take necessary measures in certain situations.

There are generally three stages in these measurements. The first step is to measure the amount of oxygen in the medium. The second stage is to detect flammable gases and vapors in the environment. The third stage is the measurement of toxic gases in the environment.

First, the amount of oxygen is measured. This is because the presence of oxygen in the environment is utilized for proper operation of the devices used in the second stage. These devices do not give reliable results if the amount of oxygen is not sufficient. The presence of toxic gases and vapors is carried out at the last stage since it carries a lower risk than the risk of fire or explosion caused by flammable gases.

The definition of closed area includes silos, pipelines, water tanks, sewage plants, wells, canals, oil tanks, waste tanks, tankers and storage tanks.

There are two types of hazards that can occur in confined spaces. These are either hazards due to limited space or hazards from work done in the environment.

The effects of indoor oxygen levels on human health are as follows:

• Percent 22: Oxygen-rich medium
• Percent 21: Normal level (safe for entry)
• Percent 20: Oxygen-insufficient environment
• Percentage 16: Decision making and breathing disorder
• 14 percent: Fatigue and wrong decision
• 11 percent: Difficulty breathing and death within minutes

Depending on the type of activity, there may be decreases in the oxygen level in the indoor area. Lack of oxygen causes loss of consciousness and death. Lack of oxygen is the greatest danger in confined spaces. Therefore, oxygen measurements should be carried out by authorized laboratories in the workplaces.

Our company performs oxygen (O) measurements within the scope of gas measurements. In these studies In accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations.

In the meantime, our organization, ÖSAS Accreditation Agency, Accredited according to TS EN ISO / IEC 17025 standard.
