1 SODIUM SILICATES 1. CHEMICAL PRODUCT PRODUCT NAME: SUPPLIER : Sodium Silicate PROCOR STEEL TRADERS P.O.Box DOWERGLEN, 1608 TELEPHONE NUMBER (011) EMERGENCY TELEPHONE NUMBER+27(0) FAX NUMBER (086) COMPOSITION INFORMATION ON INGREDIENTS CHEMICAL FAMILY Silicate CONTAINS 40% to 55% Sodium Silicate and the balance is Water CAS NUMBER HAZARDS IDENTIFICATION Classified "Irritant" under rules of the EEC "Dangerous Substance Directive" 67/548/EEC as amended by 92/32EEC Alkaline solution. Risk of serious damage to eyes. Irritating to skin. 4. FIRST-AID MEASURES EYE SKIN CONTACT INHALATION INGESTION Eye wash facilities must be kept close at hand. Wash immediately with copious amounts of water then obtain medical attention without delay. Wash skin thoroughly with water and remove any contaminated clothing. Obtain medical attention if any symptoms develop. Remove to fresh air. Get medical attention if irritation persists. Do not induce vomiting. Remove material from mouth. Drink 1 to 2 glasses of milk and obtain medical attention.

2 5. FIREFIGHTING MEASURES. Aqueous solution. Will not support combustion. 6. ACCIDENTAL RELEASE MEASURES Wear goggles to protect eyes. If possible contain spillage and absorb in earth or sand and shovel into suitable containers. If containment is not possible and the material enters the drains, dilute as much as possible with water and immediately notify the authorities. Spillages unless dealt with promptly may set to a glass and become slippery. 7. HANDLING AND STORAGE SPECIAL SENSITIVITY No special sensitivity HANDLING/STORAGE Do not store at temperatures above 50 degrees celsius for prolonged periods. Do not allow to freeze. VENTILATION REQUIREMENTS SENSITIVE TO STATIC ELECTRICITY Normal ventilation is adequate. No 8. EXPOSURE CONTROLS / PERSONAL PROTECTION EXPOSURE LIMITS VENTILATION REQUIREMENTS EYE PROTECTION REQUIREMENTS GLOVE REQUIREMENTS CLOTHING REQUIREMENTS RESPIRATORY REQUIREMENTS (UK EH40/93) Not listed Sodium Hydoxide has an exposure limit of 2mg/m3 (10 min TWA). When using Sodium Silicate it is recommended that exposure to alkalinity is, calculated as NaOH, should be kept below this limit. Local exhaust ventilation if solution is sprayed or forms an airborne aerosol. Otherwise no special controls are necessary. Safety glasses, goggles or face shield to protect against splashing. Impermeable plastic or rubber gloves. Acid resistant overalls, or lab coat should be worn. None required if good ventilation is maintained. If solution is sprayed a suitable respirator should be worn.

No odour ph AS IS > 12 BOILING POINT MELTING SOLUBILITY IN WATER > 100 C approx 0 C approx Soluble RELATIVE DENSITY Approx 1.4 to 1.6 VAPOUR PRESSURE (mmhg) VISCOSITY VOLATILE ORGANIC COMPOUNDS AUTOFLAMMABILITY FLASH POINT EXPLOSION PROPERTIES 200 to C 10. STABILITY & REACTIVITY STABILITY MATERIALS AND CONDITIONS TO AVIOD Stable May react with Aluminium, Zinc, Tin and their alloys evolving Hydrogen gas. Dilute solutions of less than 10% have zero or minimal effect on these metals. If arc welding is carried out on vessels containing silicate solutions electrolysis may occur. Circuits must not be completed through pipes containing valves, bolted flanges or threaded joints. May react violently with acids Food or dairy residues may contain sugars which under certain conditions may react with alkaline materials evolving carbon monoxide. Ensure adequate ventilation before entering confined spaces.

4 HAZARDOUS DECOMPOSITION PRODUCTS None known. 11. TOXICOLOGICAL INFORMATION The primary hazard of Sodium Silicate by all routes is it's alkalinity. INGESTION INHALATION EYE CONTACT SKIN CONTACT The toxicity of Sodium Silicate is dependant on the Silica to alkali weight ratio and on the ph. LD50 oral rat values are in the range of mg/kg. Unless the solution is sprayed or otherwise becomes an airborne aerosol, inhalation is unlikely. Irritation of airways is the likely effect. Severely irritating. May cause severe damage to eyes. Irritating to skin 12. ECOLOGICAL INFORMATION Soluble Silicates, upon dilution, rapidly depolymerise into molecular species indistinguishable from natural dissolved silica. However the ph of most Silicate solutions is above the acceptable limits for discharge to drains or watercourses. 13. DISPOSAL CONSIDERATIONS WASTE DISPOSAL METHODS Waste disposal should be in accordance with existing Community, National and local regulations. 14.
