Interesting facts about dispensing systems
Dispensing system - definitely more relaxed
Use of beverage dispensing systems DGUV Rule 110-007 (excerpt)
Beverage dispensing systems are systems from which drinks are dispensed for final consumption, with or without operating pressure, ... e.g. beer, wine, wine-based hot drinks, non-alcoholic soft drinks, water, smoothies and spirits.
To ensure adequate personal protection, gas warning systems must be used in accordance with DIN 6653-2 “Drink dispensing systems – Equipment – Part 2: Requirements for the operating behavior and test methods of carbon dioxide warning systems.”
Gas detection systems must be equipped with at least two alarm thresholds. The pre-alarm is triggered at a carbon dioxide concentration of 1.5 vol% and above, and the main alarm at 3 vol% and above. The pre-alarm and main alarm must be visually and audibly distinguishable from each other.
In order to ensure that escaping gas is detected in a timely and safe manner, the following requirements in particular must be met:
The measuring locations must be selected so that the gases escaping in the area to be monitored are detected in a timely and reliable manner by the sensors of the gas warning system. The sensors should preferably be installed approximately 30 cm above the floor. If there is a risk of damage to the sensor, a protective device (e.g. protective bracket) must be installed.
the visibility of the alarm and fault signalling device of the gas warning system must be ensured outside the endangered area, i.e. in the safe area (e.g. in the upper area of the cellar stairs at eye level),
In addition, the alarm and the fault message must be perceptible in the danger zone (e.g. in the walk-in cold room), and the alarm must be indicated visually and acoustically by a perceptible signaling unit (e.g. warning light/horn) for all entrances to the endangered area.
In the event of a main alarm, no person may enter the endangered area or room without respiratory protection (independent of recirculation air).
