OM-498 Page 2 W elding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks c a n fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire.
OM-498 Page 3 MOVING P ARTS can cause injury . Keep away from fans, belts, and rotors. Keep all doors, panels, covers, and guards closed and securely in place. Stop engine before installing or connecting unit. Have only qualified people remove guards or covers for maint- enance and troubleshooting as necessary .
