SECTION V I I - PREVENTIVE MEASURES
Steps to be Taken in Case Material is Released or Spilled:
Collect spilled material and return to process. Use a shovel rather than sweeping if possible to avoid dust conditions. Return to salvage or process if possible. Dispose of according to appropriate federal, and local regulations.
Waste Disposal Method:
Respiratory Protection: When engineering controls are not feasible to control overexposure, use appropriate NIOSH approved dust/fume respirators.
Local Exhaust: Engineering Controls
Essential to keep worker exposure within allowable limits during welding or grinding.
Mechanical ( General ):
As needed to protect against physical hazards.
Safety glasses, or goggles, face shield.
Other Protective Equipment: ::
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 evaluation done Special Precautions and Waste Disposal Methods: Do not dispose of in sewers or any body of water. Return to manufacturer or dispose of according to local regulations.
