AR63.20-S-1107-02P | Partially prepare A-pillar for installation | ||
Danger | The high voltage used for electric welding presents a lethal hazard. Risk of explosion from welding in areas close to highly inflammable materials. Risk of injury from weld splatter and UV-light when welding. Risk of poisoning from inhaling welding gases | Use insulating mats. Wear protective clothing, safety glasses and a protective mask. Remove highly inflammable materials from the hazard area. Use air extraction system. | |
Caution | Risk of injury caused by scraping or cutting body parts on sharp vehicle parts | Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. | |
