| Risk of explosion caused by welding or soldering work on closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerant. | Do not perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been drained. | AS83.00-Z-0001-01A | |
| Risk of death when touching components on vehicles with high-voltage on-board electrical system | Do not touch components and open lines of the high-voltage on-board electrical system. Persons who wear electronic implants (e.g. cardiac pacemakers), must not carry out any work on high-voltage on-board electrical systems. | AS54.00-Z-0001-01A | |
