3. Hazards Identification

Emergency Overview

CAUTION! MAY BE HARMFUL IF INHALED. MAY CAUSE IRRITATION TO SKIN, EYES, AND RESPIRATORY TRACT.
 
Hazard Ratings (Provided here for your convenience)
Health Rating: 2 - Moderate (Life)
Flammability Rating: 2 - Moderate
Reactivity Rating: 1 - Slight
Contact Rating: 1 - Slight
Protective Equip: GOGGLES; CLOTHING; VENT HOOD; GLOVES
Storage Color Code: Green (General Storage)
 

Potential Health Effects

Inhalation: No adverse effects expected but dust may cause mechanical irritation.
Ingestion: Large doses may cause nausea, vomiting, and diarrhea.
Skin Contact: No adverse effects expected. May cause mild irritation and redness.
Eye Contact: No adverse effects expected but dust may cause mechanical irritation.
Chronic Exposure: Prolonged inhalation of the dust or fume may result in a benign pneumoconiosis, producing distinctive changes in the lungs with no apparent disability or complications.
Aggravation of Pre-existing Conditions: No adverse health effects expected.
 
4. First Aid Measures
Inhalation: Not expected to require first aid measures. Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
Skin Contact: Not expected to require first aid measures. Wash exposed area with soap and water. Get medical advice if irritation develops.
Eye Contact: Wash thoroughly with running water. Get medical advice if irritation develops.
 
5. Fire Fighting Measures
Fire:
Autoignition temperature:
Dust Cloud : 630C (1166F);
Dust Layer: 430C (806F).
Explosion:
Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Minimum explodable  concentration: 0.19 g/l Particle size and air concentration determine reactivity.
Fire Extinguishing Media:
USE dry sand, graphite, dolomite, sodium chloride. NEVER USE water, halogenated agents, or class A, B, or C extinguishers.
Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire.
 
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools and equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container.
 
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from any source of heat or ignition. Avoid dust dispersal. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
 
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL): 2 mg/m3 (TWA)
-ACGIH Threshold Limit Value (TLV): 2 mg/m3 (TWA)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, a half facepiece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
 
9. Physical and Chemical Properties
Appearance: Uniform, silvery granules or mossy flakes.
Odor: Odorless.
Solubility: Insoluble in water.
Density: 7.31
pH: No information found.
% Volatiles by volume @ 21C (70F): 0
Boiling Point: 2507C (4545F)
Melting Point: 231.9C (450F)
Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): 1 @ 1609C (2928F)

10. Stability and Reactivity
Stability:
Powder will oxidize, especially in the presence of moisture. Metal normally has a protective film of stannic oxide which thickens as the temperature is raised.
Hazardous Decomposition Products: No hazardous decomposition products.
Hazardous Polymerization: Will not occur.
Incompatibilities: Halogens and halogen trifluorides, cupric nitrate, sodium and potassium peroxide, sulfur, and some acids.
Conditions to Avoid: Heat, flames, ignition sources and incompatibles.
