Gas, steam, dust and smoke are the most important chemical factors that threaten the health of the employees in the workplace. Basically, a chemical is encountered wherever the environment is looked. Paint, insulation, fuel for vehicles, fabric of garments, various medicines, pesticides and fertilizers are all alongside chemicals. However, the production and use of these chemicals are among the main factors in the economic development of countries. These statistics reveal surprising facts. There are over five million different chemicals in the world. Annual chemical production is around 400 million tons. Almost ten thousand of the chemicals produced are considered dangerous for human health. Moreover, nearly two hundred of them are cancerous. Every year, around one thousand new chemicals are produced and marketed on average. However, despite this development, it cannot be said that everything is known about how the health of those producing and using these chemicals is affected.

In fact, the production, use, modification of natural substances or the production of new substances by synthetic means is an intervention in the balance of nature. Although human life is facilitated on the one hand, it also creates harmful consequences for human health. Although some of these damages are tolerated, some of them pose risks to living things and ecosystems.

For this reason, on the one hand, while defining the criteria and limits for the protection of the employees and those affected by chemicals with legal regulations, a number of standards are established by domestic and foreign organizations.

Authorized laboratories carry out measurement and analysis studies for protection from chemicals and make chemical factor mapping to the enterprises and make the risky areas of the enterprise more prominent. This makes it easier for businesses to understand risks and take precautions.
