SECTION IV            FIRE AND EXPLOSION HAZARD DATA

 

 

Flashpoint: N/A        Auto-ignition temperature: N/A                     Flammability limits: N/A

 

In the solid form, there are no fire or explosion hazards with this alloy.

Fine chips or dust may ignite and should be stored in a well-ventilated area.

In case of fire, use extinguishing agents appropriate for the surroundings or materials. Dry chemicals or sand should be used to extinguish fires. Fire fighters should wear full protective clothing and where conditions warrant NIOSH-approved self-contained breathing apparatus, see Sections VI and VII.

 

 

SECTION V             REACTIVITY DATA

 

 

Copper and Copper alloys are stable under normal conditions of transport, use and storage.

 

SECTION VI            HEALTH HAZARD DATA

 

 

TLV:                                See Section II

 

Primary Routes of Entry: Inhalation of dust or fumes

 

Copper: Under normal handling and use, exposure to the solid form of copper or copper alloys presents few health hazards. Thermal cutting, melting, machining/grinding may produce fumes or dust containing the component elements, and breathing these fumes or dust may present potentially significant health hazards. The exposure levels in Section II are relevant to fumes and dust. Fumes of copper may cause metal fume fever with flu-like symptoms, and copper may cause skin and hair discoloration.

 

Zinc: Overexposure to zinc fumes may cause nonfatal metal fume fever

 

Lead: Inhalation of lead fumes or dust, or ingestion of lead compounds, can cause lead poisoning, characterized by abdominal pain, joint and muscle pains, or weakness. Prolonged overexposure can cause central nervous system disorders.

 

Nickel: Excessive inhalation of nickel fumes has been associated with respiratory cancer. Also, nickel is a potential sensitizer, and thus may cause allergic reactions

 

Manganese: Excessive and prolonged inhalation of manganese (generally over 2 years exposure) can cause damage to the central nervous system, resembling Parkinson's Disease.

 

 

SECTION VII          SPILL, LEAK AND DISPOSAL PROCEDURES

 

 

No special precautions are necessary for spills of bulk material. If large quantities of dust are spilled, remove by vacuuming or wet-sweeping to prevent heavy concentrations of airborne dust. Cleanup personnel should wear respirators and protective clothing. Scrap metal can be reclaimed for reuse. Follow Federal, State and Local regulations regarding disposal.

 

SECTION VIII          SPECIAL PROTECTION INFORMATION

 

 

Use general and local exhaust ventilation to keep airborne concentrations of dust and fumes below the TLV. When required, employees should wear MSHA- or NIOSH-approved respirators for protection against airborne dust or fumes. Approved safety glasses and/or goggles should be worn during any machining, grinding, cutting or other operation from which airborne particles may be emitted. Food or drink should not be consumed in the work area.

 

SECTION IX            SPECIAL PRECAUTIONS AND COMMENTS

 

 

Use good housekeeping practices to prevent accumulations of dust and to keep airborne dust concentrations at a minimum. Avoid breathing dust or fumes. Store dust away from source of ignition.
