2.3 General safety measures

Keep tank covers closed at all times. Never leave open tank covers unattended.
Tank covers may be opened for inspection and maintenance purposes only. There is a
danger of persons or animals falling into the tank. This may result in serious injury or
drowning.
Keep unassigned persons, in particular children, away from open tank covers.
Closed tank covers must resist all attempts by a child to open them.
Before closing, make sure that there are no persons or animals in the tank.
Keep switch cabinets closed at all times. Never leave an opened switch cabinet
unattended.
Switch cabinets house components that may be hot to the touch. Touching these may
cause burning injuries.
Unauthorised access to the controller may cause serious malfunctions.
Open the switch cabinet only for the purpose of operating or servicing the plant.
At the end of the work, close and lock the cabinet.
Operate the controller only when it is in perfect working condition
Any damage, however slight, to the controller's housing or the wiring insulation poses
a risk of electric shock.
Immediately on signs of damage, shut down the plant, disconnect it from its power
supply, and commission a specialist for its repair.
Do not place any receptacles containing liquids on the switch cabinet.
Spilled or discharging liquids may cause short circuits. Fire or electric shock may be
the consequence.
Do not transport or deposit any substances hazardous to water near the tank
cover.
Wear personal protective equipment (PPE)
PPE (protective gloves, goggles, safety shoes, etc.) protects the wearer against injury
and harm to health.
Whenever necessary, wear the prescribed protective equipment.
Do not use damaged or defective protective equipment, which must be replaced
immediately with fully functional equivalents.
