Various occupational diseases threaten employees who have to work with chemical substances in their working environments. At the same time, the working environment must be protected against risks arising from chemical substances and necessary precautions should be taken. For these reasons, it is important to make gas measurements in work environments in terms of occupational health and safety. The limit values ​​for some chemicals during gas measurements are contained in current legal regulations.

Depending on the field of activity, various gases and vapors are introduced into the air in some workplaces and this requires effective measures to be taken in the working environment. For example, there may be adverse weather conditions such as oxygen deficiency or excess in working environments, the presence of flammable gases or the presence of certain toxic gases. In order to detect these situations and to plan the protection measures to be taken, indoor measurements should be made. According to the current regulations, these measurements, tests and analyzes must be carried out in all establishments covered by the relevant law and where chemicals are used or processed.

Businesses are obliged to use appropriate methods and appropriate machinery, materials and equipment, taking into account technological developments, in working with hazardous chemicals that pose a risk to the health and safety of employees. If collective measures to protect employees from the effects of hazardous chemicals are not sufficient, enterprises must apply personal protection methods to employees.

Authorized laboratories take into account many standards published by local and foreign organizations during their studies. Some of these standards are:

• TS EN 689 Workplace air - Guidelines for the comparison of respiratory chemicals with limited values ​​and evaluation of the measurement strategy
• TS EN 60079-29-2 Electrical devices - Used in explosive atmospheres - Part 29-2: Gas detectors - Selection, installation, use and maintenance of detectors for flammable gases and oxygen
• NIOSH 6601 Electrochemical determination of oxygen
• NIOSH 6604 Determination of carbon monoxide by electrochemical method
• ASTM-D 4490-96 Measurement of airborne concentrations of toxic gases and vapors using a detector tube
