The first step to a healthy work environment is to be informed about the regulations concerning clean air at the workspace.
We have identified four categories with different legislations; welding & cutting fumes, oil mist, vehicle exhaust and vehicle exhaust in fire stations. But these legislations have one thing in common, a maximum allowable concentration.
Every country has its own laws and regulations, which means that the a maximum allowable concentrations can also differ per country. This is inconvenient for multinational companies, so they use a corporate limit value. The reason for doing this is to make sure that air quality is kept at the best possible level, making sure that production can follow the quality standards in every country where the company is active.
