3.3 Safety Devices
This section describes all the available safety equipment and that what is to be provided by
the owner / operator. Always make sure that all the safety equipment is in perfect condition.
3.3.1 Emergency Stop
The electrical equipment of the ozone system is equipped with a red Emergency push button
with a yellow background.
The operator can connect an additional Emergency Stop device by which the ozone
production will be stopped. The control is provided with an appropriate connection option.
Ensure that the Emergency push button / device is located and identified at an easily and
safely accessible place.
Only use the Emergency push button in the event of a potential danger to life and limb or of
potential damage to the system.
Once the Emergency push button is activated, the electrical energy supply and the feed gas
flow will stop immediately.
Prior to re-starting the system, the Emergency Stop circuit must be reset.
3.3.2 Main Switch
The main switch of the ozone system is located at the side panel of the control cabinet.
By means of the main switch the complete voltage supply of the ozone generating system is
turned on or off.
Always turn off the ozone system and check for absence of voltage prior to carrying out
maintenance or repair work on the system!
3.3.3 Gas Detectors (Ambient Air Monitoring)
Ensure that rooms in which ozone leaks may occur are effectively monitored by means of
gas detectors with visual and acoustic indicators.
Such rooms are, for example: rooms containing ozone systems, rooms crossed with
removable ozone supplying pipelines.
Ensure that the monitoring device (measuring sensor) is positioned at a place where the
highest ozone concentration is to be expected in the event of a hazardous incident (at
ground level).
