  • David Street Boksburg-East THERMITREX (PTY) LTD. P.O. Box 6070 Reg. No. 71/07619/07 Dunswart, SUPPLIERS AND MANUFACTURERS OF Gauteng 1508 THERMIT® WELDING CONSUMABLES AND EQUIPMENT R.S.A. 914-2540/6 Fax : 914-2547 MATERIAL SAFETY DATA SHEET THERMIT WELDING IGNITERS In accordance with current legislation, the substance referred to below has been tested and examined to ensure, so far as is reasonably practical, that it is safe and without risk to health, if properly used. As a result, these notes have been prepared to draw attention to known hazardous characteristics and to the basic precautions to be taken by persons using the substance at work. SECTION I – MATERIAL IDENTIFICATION Material Name : Thermit Welding Igniters Other Names : Igniters Thermit “Sparklers” Thermit Igniters Pyrotechnics for technical use Application : Primarily used to initiate the Alumino-Thermic reaction Company/Undertaking Identification : Thermitrex (Pty) Ltd, David Street, Boksburg East, Gauteng, South Africa Telephone : (011) 914 2540/6 Emergency Tel. No. : 08H00 – 16H30 AT (011) 914 2540/6 Substance Identification number : UN Number 0454 class 1.4S SECTION II – COMPOSITION/INFORMATION ON INGREDIENTS AND HAZARDS CHEMICAL DESCRIPTION: HAZARDOUS DATA INGREDIENTS: Each igniter consists of a steel core wire Not regulated having a deposit fixed to one end consisting of not more than 5 grams of the following Barium Nitrate Aluminium Powder Stabiliser and Binder These igniters are packed in identified Cardboard tubes, each containing no More than 50. 1

No. 71/07619/07 Dunswart, SUPPLIERS AND MANUFACTURERS OF Gauteng 1508 THERMIT® WELDING CONSUMABLES AND EQUIPMENT R.S.A. 914-2540/6 Fax : 914-2547 SECTION III – PHYSICAL/CHEMICAL PROPERTIES Appearance : Silver/Grey stick with steel core wire protruding on one side. Odour : None. Flash point : Not applicable. Lower explosive limit : No data, this mixture is not normally present as dust. Self ignition temperature : No data, but keep away from hot surfaces above 100 ° C and naked flames. SECTION IV – FIRE AND EXPLOSION DATA Fire And Explosion Hazards Fire hazard high. The igniters has no explosive potential when ignited unconfined, but has some explosive power when strongly initiated and strongly confined. Sensitive to friction but relatively insensitive to impact. Poisonous Fumes/Vapour Burning mixture emits toxic fumes containing metal oxides and oxides of nitrogen – this is only significant when many igniters are burned simultaneously. Extinguishing Media HAZCHEM code: Rapid burning and impossible to extinguish. Keep clear. Firefighting confine to prevent spread to surrounding materials. Do not attempt to extinguish the burning igniters. Protective Measures During a fire, toxic fumes may be given off, wear breathing apparatus. For welding operations involving igniters wear heat resisting gloves, dark goggles for eye protection, safety shoes. Fire resisting clothing is recommended. SECTION V – STABILITY AND REACTIVITY DATA Stability : Stable. Conditions to avoid : Igniters should be kept dry at all times, they should be kept in a closed box only one igniter should be removed from the box at a time. Lighting of igniters should be done at arms length. The box of igniters should be kept away from the immediate welding area. Do not store large quantities of igniters together. Keep away from Thermit or other combustible materials and all means of ignition. 2

Personal Protective equipment : For welding operations involving igniters wear heat resisting gloves, dark goggles for eye protection and safety shoes. Fire resistant clothing is recommended. TOXICOLOGICAL INFORMATION ACUTE CHRONIC Skin contact When dry limited skin contact is not harmful Skin absorption When wet the requirements for the component compounds in particular barium nitrate should be followed (igniters should be kept dry at all times) Ingestion, Inhalation, Eyes FIRST AID MEASURES: Induce vomiting and seek medical treatment if a person is suspected to have swallowed the substance. Seek medical treatment when anyone has symptoms apparently due to inhalation of fumes produced in a fire. If substance or fumes produced in fire have got into the eyes, wash out immediately with water. Due to delayed effect of fumes, affected person/s should be kept under medical observation for at least 48 hours. Injuries almost invariably burns, which may be serious. Call expert medical assistance immediately. ECOLOGICAL INFORMATION Biodegradability : No Data Cited. Aquatic Toxicity : No Data Cited. Other : No Data Cited. 3

Do not flush road with water in the event of a spillage. Igniters scattered loose and possible wetted or else broken should be buried or burned in a safe place. Any “spillage” is unlikely to involve more than 50 igniters. Recovery : Broken igniters should be cleaned up using non-sparkling equipment. The use of natural bristle brushes is advised. SECTION VIII – SPECIAL PROTECTION INFORMATAION Storage : Store in dry place. Igniters should be kept in a closed box. SECTION IX – SPECIAL PRECAUTIONS AND COMMENTS Igniters have a flammable composition and burns with an intense flame. Igniters decomposes in fire, giving off toxic fumes. Handle and store igniters only as prescribed. Symptoms may develop after several hours. SECTION X – TRANSPORT INFORMATION Packaging (size and description). The sealed cardboard tubes, each containing 50 igniters, are packed 64 tubes per special cardboard box (400 mm x 320 mm x 325 mm) thus 3200 igniters per box. The nett weight of the explosive substance is 16kg. Transport Hazard symbol 1.4. S 1 = Orange label 4
