- Terms and conditions
DGUV regulation 109-002 (previously BGR 121) "Workplace ventilation - Ventilation measures" stipulates an effectiveness test in paragraph 11.2.2. This test should be carried out at regular intervals, at least once a year, as well as after changes to the system that require testing. The test may be carried out by a person qualified to carry out the test (formerly a qualified person).
Tasks and objectives of the inspection:
One component of the test is particle measurement in the exhaust air. This effectiveness test checks and documents the effectiveness and thus the function of the filter system.
After passing the test, a clearly visible test sticker is attached to the system. The test sticker shows the day of the test and the period of the next test date.
