monitoring of the system. Error messages are displayed in the main
window under "Process & equipment messages" (chapter 6.5.1.1 - "Main

Procedures in the event of hazards and accidents
Hazardous electrical incident:
• Set the control switch to the "0" position in order to interrupt the power
supply completely.
Fire:
• A fire in the electrical control system must be extinguished with a CO
2
fire extinguisher!
• Burning oil must be extinguished with a CO
2
fire extinguisher or powder
fire extinguisher!
Electric shock:
• While ensuring your
own safety
, interrupt the circuit as quickly as
possible (control switch). Keep the affected persons warm and calm.
Get medical attention immediately!
Check consciousness and
breathing continuously. In the case of unconsciousness of lack of
normal breathing, perform cardiopulmonary resuscitation (CPR).
Burns:
• Cool small-area burns (e.g. finger) immediately with cold water for
approximately 2 minutes.
• Do not cool if larger areas of the body surface are burnt since there is a
risk of hypothermia.
• Cover the burns loosely and in a sterile manner (e.g. with sterile
dressing).
• Keep the affected persons warm and calm.
IF IN DOUBT, CALL THE EMERGENCY PHYSICIAN (AMBULANCE)!
