Table 11: Grouping of installations according to the 4. ordinance
TI Air (Technical Instruction Air)
The TI Air is an administrative document on the control act (BlmSchG). It comprises
all regulations required for an installation, from first application on construction
up to monitoring the routine operation. The TI air regulates all installations
subject to licensing which are listed in the 4. ordinance.
The TI air is grouped in four parts:
• Part 1: Regulations on application areas
• Part 2: General provisions on air pollution control
• Part 3: Requirements on limitation and detection of emissions
• Part 4: Reconstruction of old installations
Part 3 of the TI air is of particular interest for gas analysis, because it includes the
specification of limit emission values of pollutants of definite installations.
Section 3.1 contains general regulations with a classification of pollutants into
4 classes: The limit value of class I substances (the most dangerous substances,
e.g phosgene) amounts to only 1 mg/m 3 while the class IV limit value (e.g. sulfur
and nitrogen oxides) is 500 mg/m 3 .
These general specifications, however, are replaced in
definite cases (section 3.3) by more strict requirements!
