1 Material Safety Data Sheet Flake Aluminium Powder 1. Basic Information: Manufacturer/ Supplier: Tetra Scene of Crime Limited 14 Carnival Park, Carnival Close, Basildon, Essex, SS14 3WE 2. Composition: Tel: (01268) Fax: (01268) Product Name: Flake Aluminium Powder (1309) Chemical: Aluminium %: >90 Classification: Highly Flammable Risk Phrases: R10-15 CAS Number: EEC Number: Physical and Chemical Properties: Appearance: Silver coloured powder Odour: Slightly waxy odour ph: N/A Melting Point: N/A Flash Point: N/A Flammability: Flammable solid Auto Flammability: Approx. 250 C Explosive Properties: L.E.L 30mg³ Oxidising Properties: N/A Vapour Pressure: N/A Density: Not determined Solubility: Contact with water must be avoided 38

2 4. Fire Fighting Procedures: Extinguishing Agents: In the case of fire, the best extinguishing agent is dry sand. Class D extinguishers with low velocity nozzles may also be used. DO NOT USE HALOGENATED HYDROCARBONS OR WATER. Special Fire Fighting Procedures: Emergency services must be notified. Aluminium powder will react with water to form hydrogen gas. Hydrogen gas is flammable and explosive. When fighting an aluminium fire, it is best to isolate the fire by encircling it with dry sand or a similar inert material, then leave alone until it has cooled. Care must be taken, as aluminium will continue to burn under a crust without any flames. Protection Requirements: Standard fire fighting equipment. 5. Stability and Reactivity: Stability: Stable under normal conditions. Hazardous polymerisation will not occur. Conditions to Avoid: Smoking, open flames, heat, and any other sources of ignition e.g. sparks from tools and static electricity. Materials to Avoid: Water, some acids, alkalies, halogenated hydrocarbons, and oxidising agents. Decomposition Products: Metal oxides, carbon dioxide, and water. Other known Hazards: React violently with water to evolve hydrogen. 6. Toxicological Information: Aluminium Acute: No toxic affects known. Chronic: Aluminium dust has been reported to cause pulmonary fibrosis though these cases are rare and are restricted to workers in the extractive industries exposed to very high levels of dust. Hence aluminium should be regarded as a nuisance dust. 39

3 7. Ecological Information: Aluminium has a low ecotoxicity. 8. Handling and Storage: Handling: Dust creation must be avoided. All equipment must be constructed to minimise dust creation, all tools must be non-sparking and non-static generating, all parts of conveying machinery must be thoroughly bonded and earthed, any electrical equipment must be suitable standard for explosive dusts. Storage: Avoid rapid rises in temperature from ambient storage temperatures. Storage under normal cover in closed drums at ambient temperatures DO NOT STORE IN DIRECT SUNLIGHT. 9. Exposure Standards/Personal Protection: Occupational Exposure Standards: Aluminium 10mg/m³ 8-hour time weighted average. Ventilation: Where dust levels are high, then Local exhaust ventilation should be provided to keep operator exposure levels below the occupational exposure standard. If extraction systems are used then consideration should be given to explosion proof equipment with explosion relief venting as aluminium powder can form explosive dust concentration in air and in ventilation systems. Explosions have occurred in these types of plant equipment. Respiratory Protection: Personal respirator cartridge filter type can be used when adequate local exhaust ventilation cannot be supplied. Skin Protection: Gloves may be worn if handling large quantities. Eye Protection: May be worn if handling large quantities. Other Special Requirements: Protective hand cream can be used to avoid possible skin irritation. This could be caused by excessive washing of the hands. 40

4 10. First Aid Measures: Eye Contact: Aluminium powder may be irritating to the eyes as any dust may be an irritant. Flush with copious amounts of water for 10 minutes. If irritation persists obtain medical advice. Skin Contact: No harmful effects have been recorded. Wash hands with mild soap and water and apply a good quality hand cream. Inhalation: As with any finely divided powder, aluminium powder may cause irritation of the respiratory system. Remove affected personnel to fresh air if the patient is unconscious keep breathing passages open. If breathing is irregular or has stopped, start resuscitation. Get medical help as the situation dictates. Ingestion: This may cause stomach pressure and nausea, give affected person copious amounts of a bland liquid such as milk obtain medical advice is symptoms are severe. IN ALL CASES IF SYMPTOMS ARE SEVERE, SEEK EXPERT MEDICAL ATTENTION. 11. Accidental Release Measures/Spillage: Protection Requirements: Remove all sources of ignition and wear protective equipment. Environmental Precautions: Prevent material from entering drains. Cleaning: Carefully collect material using non-sparking, non-static generating tools do not create dust clouds. 12. Disposal: Substance as Supplied: Disposal by a recognised disposal company. Product Packaging: Product packaging may be recycled. 41

The control of Substances Hazardous to Health EH40 Occupational Exposure Standards The Chemical (Hazard Information & Packaging for Supply) Regulations 1996 Users must make their own assessment of the risk encountered in their own individual workplace. The information contained in this sheet will provide the basic information required to undertake these assessments. Where there is a chain of supply, it is the responsibility of the consignor to provide a safety data sheet to the consignee and to check the adequacy of the information supplied. 15. Hazard Identification: Risk Phrases R10/15 Flammable, contact with water may emit flammable gas. Safety Phrases S 7/8 43 Keep container tightly closed and dry in case of fire use dry sand. NEVER USE WATER. Aluminium powders can form explosive concentrations in air, extreme care must be taken when handling or conveying powders in the correct selection of handling equipment particularly on the electrical standards of the equipment and also protection against static electricity and elimination of all other ignition sources. 42
