   Flammability 1 MATERIAL SAFETY DATA SHEET  Health 1 ? 0 Reactivity BAY STATE SURFACE TECHNOLOGIES, INC.  Hazard Rating Consistent with NFPA Code DATE: 09/25/00 SECTION I - INFORMATION  NAME AND ADDRESS EMERGENCY TELEPHONE NUMBER: (800) 772-0104 BAY STATE SURFACE TECHNOLOGIES, INC. INFORMATION TELEPHONE NUMBER: (508) 366-2456 A SUBSIDIARY OF AIMTEK, INC. 12 UNION STREET, SUITE 31 WESTBORO, MASSACHUSETTS 01581 CHEMICAL NAMES AND SYNONYMS: TRADE NAMES AND SYNONYMS:  N/A See Below Nickel Graphite Powder PP-10A, PP10AA, PP-11A, PP-11AA, 2430-175 FAMILY: FORMULA: Metal Powder N/A See Below SECTION II - HAZARDOUS INGREDIENTS/IDENTITY INFORMATION SARA Ingredient CAS # Typical % OSHA/PEL ACGIH/TLV S313  Nickel (Ni) 7440-02-0 74.0-86.0 1 mg/m 3  1 mg/m 3  313 Graphite (C) 7782-42-5 14.0-26.0 2 mg/m 3  2 mg/m 3  313 SECTION III - PHYSICAL/CHEMICAL CHARACTERISTICS MELTING POINT (ºF): N/A SPECIFIC GRAVITY (H 2 O=1): 4.09-6.18 g/cc WATER SOLUBILITY: Insoluble BOILING POINT ( o F): 5,000 PERCENT VOLATILE BY WEIGHT: 0 VAPOR PRESSURE (mm Hg): N/A EVAPORATION RATE: 0 VAPOR DENSITY: N/A APPEARANCE AND ODOR: Fine Gray Powder, No Odor SECTION IV - FIRE AND EXPLOSION HAZARD DATA FLASH POINT (Method Used): Most metal powders are combustible and can form explosive mixtures with air. FLAMMABILITY LIMITS IN AIR: LEL - Non Published , UEL - Non Published EXTINGUISHING MEDIA: Dry Powder, Dry Sand, Dry Dolomite, Dry Graphite SPECIAL FIRE FIGHTING PROCEDURES: Firefighters should wear self-contained breathing apparatus with a full facepiece. FIRE AND EXPLOSION HAZARDS: Moderate fire hazard in the form of dust when exposed to flame. SECTION V - HEALTH HAZARD DATA THRESHOLD LIMIT VALUE: See Section II CARCINOGENICITY: See Below EFFECTS OF OVEREXPOSURE:  Metallic nickel and certain nickel alloys are classified by IARC as Group 2B, possibly carcinogenic to humans, based on inadequate evidence of effects in humans. While epidemiology studies have demonstrated an increased risk of nasal, lung and possible risk of laryngeal cancer, the most likely causative agents were nickel subsulphide, nickel sulfide, and nickel oxide, with cancer linked  principally to the nickel refining process of roasting nickel sulphide ores and not to metallic nickel itself. Evidence implicating metallic nickel and nickel alloys, or the hydrometallurgical nickel refining process as respiratory carcinogens for humans is lacking. Cohort mortality studies of workers in industries in which exposure was limited to metallic nickel or the hydrometallurgical process found no association between exposure to metallic nickel and its alloys to the subsequent development of respiratory cancer. EFFECTS OF OVEREXPOSURE (continued):     SKIN: Nickel and its inorganic compounds are not absorbed through the skin. Nickel and nickel salts are known to cause contact dermatitis in sensitized individuals. Dermal or internal contact may result in the development of allergic nickel sensitivity (nickel rash) characterized by redness, inflammation, or in severe cases, skin eruptions. Nickel may be the most common sensitizer in women due to exposure to coins, watches, kitchen appliances and jewelry containing nickel. Once acquired, nickel sensitivity usually persists. Recovery usually occurs after a week but may be delayed for several weeks. EYE: Eye irritation in workers exposed to emissions from nickel electrolysis tanks has been reported. Irritation caused by mechanical abrasion from dusts is also possible. INHALATION: Exposure to nickel containing dusts has been associated with coughing and shortness of breath. Chronic changes include increased susceptibility to pulmonary edema and interstitial fibrosis. Exposure of nickel to carbon monoxide at high temperatures in the absence of oxygen may result in the formation of nickel carbonyl, an extremely toxic gas. Nickel carbonyl  produces severe pulmonary irritation which may be fatal; signs and symptoms of pulmonary effects may be delayed. INGESTION: Nickel metal and its alloys are considered to be of low toxicity for both acute and chronic ingestion exposure. Repeated or prolonged overexposure to metallic nickel can produce kidney damage. However, metallic nickel and its soluble salts have rarely produced systemic toxic effects in humans, even from therapeutic administration. Most of the nickel that is ingested remains unabsorbed passing through the gastrointestinal tract. EMERGENCY AND FIRST AID PROCEDURES: EYE CONTACT: May cause eye irritation. Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Obtain medical attention if irritation persists. MINOR SKIN CONTACT: Wash contaminated skin with soap and water. Avoid prolonged or repeated contact with the skin. Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. EXTENSIVE SKIN CONTACT: No additional information. MINOR INHALATION: Allow the victim to rest in a well ventilated area. Seek immediate medical attention. SEVERE INHALATION: No additional information. SLIGHT INGESTION: Remove dentures, if any. Have conscious person drink several glasses of water or milk. Induce vomiting. Lower the head so that vomit will not reenter the mouth and throat. Never give an unconscious person anything to ingest. Seek medical attention. EXTENSIVE INGESTION: No additional information. SECTION VI - REACTIVITY DATA STABILITY: Product is Stable CONDITIONS TO AVOID: Avoid high temperatures INCOMPATIBILITY (MATERIALS TO AVOID): Nickel reacts violently with fluorine, ammonium nitrate, hydrazine, performic acid, phosphorous, selenium, sulfur and titanium plus potassium chlorate. Nickel is also incompatible with oxidizers. HAZARDOUS DECOMPOSITION PRODUCTS: Toxic gases and vapors (Nickel Carbonyl and oxides of Nitrogen) may be released in a fire involving nickel. HAZARDOUS POLYMERIZATION WILL NOT OCCUR. SPECIAL REMARKS ON REACTIVITY: Nickel is soluble in acids. Contact with mineral acids liberates hydrogen gas which may form explosive mixtures in air. Under the right conditions (high pressure, high carbon monoxide concentration) toxic nickel carbonyl gas may be formed. SECTION VII - SPILL OR LEAK PROCEDURES  STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Wear protective equipment and clothing. Collect spilled material for reclamation or disposal in sealed containers. Avoid inhalation of dust. Remove sources of heat or ignition. Keep airborne dust at minimum when cleaning up. WASTE DISPOSAL METHOD: Recycle or dispose of in accordance with Federal, State and Local regulations. SECTION VIII - PERSONAL PROTECTION INFORMATION RESPIRATORY PROTECTION: Use NIOSH approved respirators where concentrations of dust and fumes exceed PEL or TLV. VENTILATION PROTECTION: Provide local ventilation or general dilution to maintain exposures below TLV-TWA. EYE PROTECTION: Use safety glasses with side shields or goggles where appropriate. PROTECTIVE GLOVES: Aluminized gloves are to be worn during the plasma spray process. Rubber or other appropriate gloves may be worn as necessary during other phases of product handling. CLOTHING: An aluminized apron is to be worn during the plasma spray process. Other appropriate clothing may be worn as necessary during products handling to avoid excessive contact with skin. SECTION IX - SPECIAL PRECAUTIONS Provide general and local exhaust ventilation to meet TLV requirements in the workplace. Where workers are exposed to dust, approved respirators are to be worn. Protective clothing should be changed on a daily basis. An eyewash station should be readily accessible to areas of use.
