Many substances do not have a unique exposure limit. The absence of it does not lessen consideration for exposure risk. In the
absence of specific information professional judgment may be required.

Unusual Fire and Explosion Hazards - N/A
SECTION V - REACTIVITY DATA
Stability - Stable Conditions to avoid - N/A
Incompatibility - Reacts with strong acids to liberate explosive hydrogen gas
Hazardous decomposition or byproducts - Metallic oxides or metal fumes may be produced during melting operations
SECTION VI - HEALTH HAZARD DATA
Routes of Entry Inhalation? Skin? Ingestion?
yes no yes
Health Hazards
Acute - Inhalation of fumes may result in chills and fever for 12 o 48 hours. Metal fume fever -- metallic taste, throat irritation, and
flu-like symptoms.
Chronic - Chromium, manganese and nickel fumes may cause lung disease, lead fumes can damage kidneys and affect muscle
strength.
NTP: Arsenic, nickel, chromium, cadmium
Carcinogenic -
IARC: Arsenic, nickel, chromium, cadmium, lead
OSHA: Arsenic
Signs and Symptoms of Exposure - Nausea, tightness of chest, fever, irritation of eyes, nose, throat, and skin
Medical Conditions Generally Aggravated by Exposure - Chronic lung disease, allergic conditions.
Dust, welding fumes -- remove to fresh air.
Emergency and First Aid Procedures -
Eye/skin contact -- flush with water.
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
Steps to be Taken in Case of Release or Spill - Chips and dust should be swept up and placed in suitable container. Prevent
release to sinks, drains, sewers, or water runoff.
Waste Disposal Method - Material not known to be a RCRA hazardous waste, follow local requirements.
Precautions to be Taken in Handling and Storing - Use good housekeeping to minimize particle accumulation.
Other Precautions - Ventilate welding, brazing, and grinding operations.
SECTION VIII - CONTROL MEASURES
Respiratory Protection - Dust/fume respirator
Local Exhaust - Required for welding, grinding operations
Protective Gloves - As needed based on operations
Eye Protection - As needed
Other Protective Clothing or Equipment - May be needed for welding or grinding
