Metallic taste, abdominal cramps,frequent headaches. Give water or milk. If conscious, induce vomiting. Seek medical aid. Molten magnesium could splash into eye. Flush with cool water for 15 minutes and seek immediate medical aid. Not considered a significant risk in this application. Remove contaminated clothing and wash affected area with soap and water. Dust particles can cause lesions called "Chemical Gas Gangrene". Fumes from welding, dust from grinding can in excess cause "Metal Fume Fever". Remove the victim and get medical aid.

SECTION V I I - PREVENTIVE MEASURES
Steps to be Taken in Case Material is Released or Spilled:
If solid, wear gloves, pick up and return to process. If dust, wear personal protection and use a vacuum. Return to process. Firefighters can approach a magnesium fire with in a few feet if no moisture present. Waste Disposal Method: Magnesium turning should be collected in a dry metal covered container labeled "For Magnesium Only". Magnesium dust collected with special equipment. Respiratory Protection: Wear approved fume / dust respirator if exposure limit at or near exposure limit. Use to maintain ambient levels below permissible exposure limits (PEL). SCBA required when levels are unknown.
Local Exhaust: Engineering Controls Mechanical ( General ):
Cotton or other cloth glove.
Safety glasses, goggles, face shield if molten.
Other Protective Equipment: ::
Heat resistant leggings and gloves if pouring molten magnesium.
SECTION V I I I - SPECIAL PRECAUTIONS
Precautions to be Taken in Handling and Storing:
The scrap metal itself presents no health hazard unless it is welded, burned, ground, or cut. Possible fumes.may be generated. Should have complete medical evaluation done. Special Precautions and Waste Disposal Methods: Do not dispose of into municipal garbage. Do Not Dispose of into sewers or any body of water. Do Not Dispose of in a landfill site. Follow local or Federal guidelines for disposal. Take to a recycle or scrap dealer, or secondary smelter. SECTION IX - PREPARATION INFORMATION
