The maximum workplace concentration indicates the maximum permissible concentration of a substance as a gas, vapor or suspended matter in the air at the workplace. The values set in each case are a compromise when weighing up possible damage to health as well as the risks and costs. The Swiss Accident Insurance SUVA publishes a table with maximum exposure values, which is freely accessible on their website.
The short-term limit value is the value that must not be exceeded even in the short term. This indicates that the mean value of a 15-minute measurement must not exceed the short-term limit.
The following are the most common gas compounds and SUVA guidelines. The complete list is freely accessible in Excel format on the SUVA website.
