IV - FIRE AND EXPLOSION HAZARDS DATA

FLASH POINT: Ingot or solid chunks will not flash. Fines resulting from cutting, grinding or handling can present an explosion hazard when airborne in levels above 35g/m3. (U.S. Bureau of Mines, Report of Investigation No. 4835).

EXTINGUISHING MEDIA AND FIRE & EXPLOSION HAZARDS: Use National Fire Protection Association Class D extinguisher (salt). Use salt or sand to reduce oxygen access. Fire may be isolated and allow to burn itself out. Do not spray with water or liquids. Fire or Explosion may be initiated by exposing the concentrated suspension in an enclosed area to spark or flame. Generally Titanium based metal dust or powder must be minus 100 mesh in order to create an explosive dust-air mixture.

V - HEALTH HAZARD INFORMATION

No other effects other than exposure to metal dust. ACGIH classifies Titanium base fines as a nuisance dust.

EFFECTS OF OVEREXPOSURE: (ACUTE AND CHRONIC)

Effects associated with overexposure of alloyed elements in metal dust of fumes may include respiratory irritation, conjunctivitis, pneumoconiosis, etc. The presence of nickel and/or chromium in selected lots may constitute a potential carcinogen. Nickel metal has been identified by IARC as a carcinogen to humans.

VI - REACTIVITY DATA

STABILITY: Stable

CONDITIONS TO AVOID: Contact between Ferrotitanium and certain acids may liberate Hydrogen gas. Contact with red fuming nitric acid may result in violent reaction.

INCOMPATIBILITY: none

HAZARDOUS DECOMPOSITION OR BY PRODUCT: None

VII - SPILL OR LEAK PROCEDURES

No special steps necessary

VIII - SPECIAL PROTECTION INFORMATION

VENTILATION: Provide sufficient ventilation and administrative controls to keep exposure below permissible limits.

RESPIRATORY PROTECTION: Use NIOSHA approved respiratory protection if metal bust becomes airborne.

OTHER CLOTHING AND EQUIPMENT: During crushing use hard hat, face shields and gloves.

EYE PROTECTION: Safety glasses

IX - SPECIAL PRECAUTIONS

Fine dust suspended in air may ignite or explode. Contact between Ferrotitanium and certain acids may liberate Hydrogen gas. Contact with red fuming nitric acid may result in violent reaction.
