----------------------------------------------------------5 - SECTION 4 - FIRE AND EXPLOSION HAZARD DATA ----------------------------------------------------------FLASH POINT (Method Used): N/A Specialty/stainless steel products in the form shipped are not considered combustible. During subsequent processing (cutting, welding, grinding, etc.) the generation of dust in high concentration may present fire and explosion hazards. FLAMMABLE LIMITS: N/A LEL: UEL: EXTINGUISHING MEDIA: Class D if required. SPECIAL FIRE FIGHTING PROCEDURES: Use no water. UNUSUAL FIRE AND EXPLOSION HAZARDS: N/A ----------------------------------------------------------6 - SECTION 5 - HEALTH HAZARD DATA ----------------------------------------------------------PRIMARY ROUTE OF EXPOSURE: Inhalation of fumes from welding or burning. ROUTE(S) OF ENTRY: INHALATION: Yes SKIN: Yes INGESTION: Yes OTHER: Eyes NOTE: Steel, when subjected to welding, burning, sawing, brazing, grinding, etc. may generate potentially hazardous fumes or dust. The above operations should be performed in well ventilated area. The primary route of exposure is from inhalation of fumes and dust. These operations should conform to the requirements of 29 CFR 1910.252. TLV-TWA of 5 mg/M3 for welding fume - total particulate matter N.O.C., (not otherwise classified). EFFECTS OF OVEREXPOSURE: ACUTE: Excessive inhalation of metallic fumes and dusts may be irritating to respiratory passages. Excessive inhalation of fumes from metals such as copper can produce an acute reaction known as metal fume fever. Symptoms consists of chills and fever, which come on a few hours after high levels of exposure. CHRONIC: Prolonged over exposure to alloy dusts or fumes may cause skin, eye, throat or nose irritations, leading to pulmonary diseases. Excessive and repeated inhalation of chromium and nickel fumes or dust may cause severe irritation, ulceration and increased risk of cancer in the respiratory system. Can cause damage to the central nervous system - specifically leading to symptoms resembling Parkinson's Disease. IRON OXIDE: Chronic inhalation of excessive concentrations of iron oxide fumes and dusts may result in development of a benign pneumoconiosis, called siderosis, which is observable as an x-ray change. No physical impairment of lung function has been associated with siderosis. Inhalation of excessive concentrations of ferric oxide may enhance the risk of lung cancer development in workers exposed to pulmonary carcinogens. MANGANESE: Chronic exposure to high concentrations of manganese fumes and dusts may increase the incidence of pneumonia and lung damage and may adversely affect the central nervous system with symptoms including languor, sleepiness, weakness, emotional disturbances, spastic gait, mask-like facial expression and paralysis. Animal studies indicate that manganese exposure may increase susceptibility to bacterial and viral infections.

NICKEL: Nickel fumes are respiratory irritants and may cause pneumonitis. Skin contact may cause an allergic rash. Nickel itch is the dermatitis resulting from sensitization to nickel; the first symptom is usually itching which occurs up to seven days before skin eruption occurs. The primary skin eruption is orythematous, or follicular, which may be followed by skin ulceration. Nickel sensitivity, once acquired, is apparently not lost. All airborne nickel contaminating dusts are regarded as carcinogens via inhalation. The international agency for research on cancer (IARC) and the National Toxicology Program (NTP) list nickel as a known human carcinogen. The American Conference of Industrial Hygienists (ACGIH) proposed to list nickel as a carcinogen in the 1989-90 TLV's. CHROMIUM: The health hazards associated with exposure to chromium are dependent on its oxidation state. The metal form (chromium as it exists in this product) is of very low toxicity, however, exposed to certain processes various oxidation states of chromium may be formed. The hexavalent form is very toxic. Adverse effects of the hexavalent form on the skin may include ulcerations, dermatitis and allergic skin reactions. Inhalation of hexavalent chromium compounds can result in ulceration perforation of the mucous membranes of the nasal septum, irritation of the larynx and pharynx, asthmatic bronchitis and edema. Respiratory symptoms may include coughing and wheezing, shortness of breath and nasal itch. Eye irritation or inflammation may also result. IARC and the NTP lists chromium compounds as a known human carcinogen. ACGIH has reviewed the toxicity data and concluded that chromium metal is not carcinogenic to humans, but certain insoluble, hexavalent compounds to be so. TITANIUM DIOXIDE: Titanium dioxide dust is a mild pulmonary irritant, eye and skin irritant and may be a potential carcinogen. Laboratory animals (rats) exposed to titanium dioxide developed small focal areas of emphysema which were attributable to large deposits of dust. Excessive exposure in humans may result in slight changes in the lungs. SILICON: Elementary silicon is an inert material which appears to lack the property of causing fibrosis in lung tissue. However, slight pulmonary lesions have been reported in laboratory animals from intratracheal injections of silicon dust. Silicon dust has little adverse effect on lungs and does not appear to produce significant organic disease or toxic effects when exposures are kept under the TLV. Silicon may cause chronic respiratory effects. MOLYBDENUM: Molybdenum is not foreseen as a hazard in the present context. Though molybdenum has caused toxicity (anemia and poor growth) in farm animals, there is not data documenting toxicity to humans due to industrial exposure; however, molybdenum may cause lung disease and irritation. COPPER: Industrial exposure to copper fumes, dusts or mists results in metal fume fever with atropic changes in nasal mucous membranes. Chronic poisoning results in Wilson's Disease, characterized by a hepatic cintosis, brain damage, demyollnation, renal disease and copper deposition in the cornea. HEALTH AND FIRST AID PROCEDURES: INHALATION: Remove to fresh air, get medical attention. SKIN: Wash areas well with soap and water. Get medical attention. EYES: Flush well with running water to remove particulate. Get medical attention. INGESTION: In the unlikely event that large quantities of metal have been ingested, get medical attention.

----------------------------------------------------------7 - SECTION 6 - REACTIVITY DATA ----------------------------------------------------------STABILITY: Stable CONDITIONS TO AVOID: Avoid generation of airborne dust which presents moderate fire and explosion hazards. INCOMPATIBILITY (Materials to Avoid): Acids, bases and oxidizers. Molten metal will react violently with water. HAZARDOUS DECOMPOSITION PRODUCTS: Metal Fumes: Iron Oxide, Manganese, Chromium, Nickel, Molybdenum and Titanium Dioxide when welding or burning. HAZARDOUS POLYMERIZATION: Will Not Occur CONDITIONS TO AVOID: N/A ----------------------------------------------------------8 - SECTION 7 - SPILL OR LEAK PROCEDURES ----------------------------------------------------------STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Fine material should be swept or vacuumed. Avoid using compressed air to maneuver spills or leaks of dusty material to avoid eye contamination and dispersion into ambient air. WASTE DISPOSAL METHOD: Dispose of in accordance with applicable federal, state and local regulations. Scrap metal may be reclaimed for reuse. ----------------------------------------------------------9 - SECTION 8 - SPECIAL PROTECTION INFORMATION ----------------------------------------------------------RESPIRATORY PROTECTION (Specify Type): Use general and local exhaust ventilation to keep airborne dust or fumes below established TLV's. Employees should wear NIOSH approved respirators for protection against dust or fumes when established TLV's are exceeded. The TLV for total dust is 10.00 mg/m3 and for respirable dust the TLV is 5.00 mg/M3. VENTILATION: Local exhaust ventilation should be used to keep worker exposure below accepted exposure limits during welding and grinding operations. PROTECTIVE GLOVES: Use of gloves is recommended. EYE PROTECTION: Appropriate protective eyewear is recommended. OTHER PROTECTIVE EQUIPMENT: Principles of good personal hygiene should be followed prior to changing into street clothes or eating. Food should not be consumed in the work area. ----------------------------------------------------------10 - SECTION 9 - SPECIAL PRECAUTIONS ----------------------------------------------------------PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING: Store material away from incompatible materials and also keep dust and fume away. OTHER PRECAUTIONS: Metallic and non-metallic coatings may be applied to the product at the customers request. These are usually classified as protective coatings or lubricants. The possible presence of coatings should be recognized and considered when evaluating potential employee hazards and exposures during dust/fume generating activities and potential safety and fire hazards during handling. Any applicable coating MSDS is attached to this data sheet. Any non-metallic coatings which may be applied to this product only represent a small percentage of the total weight of the product.
