EU Classification

Regulation(EC) No. 1272/2008 (which replaces Directive 67/548/EC(DSD)

2.1 Classification of the substance or mixture

Not classified. GGBFS does not meet the crtiteria for classification in accordance with the regulations EC1272/2008. No special conditions are therefore needed. Risk management measures due to the potential occurrence of hazardous dusts during use as an abrasive may be needed. .

2.2 Label elements

Labelling according to Regulation (EC) No 1272/2008 (which replaces Directive 67/548/EC(DSD) None

2.3 Other hazards

Blast furnace and Steel-making Slag constitute a LOW RISK substance when associated with intended use and handles in much the same manner as dry cement. However since this substance has cementaceous properties and is often blended with Ordinary Portland Cement (OPC) it will liberate highly alkaline solutions when in contact with water in association with its intended use. The user should consult Safety Data Sheets of Ordinary Portland Cement intended construction products - concrete and mortar. Hazards associated with blast furnace and Steel-making Slag are synonymous with Ordinary Portland Cement and are classified under CHIP 3 2002 (Approved Classification and Labelling Guide – 5th edition) as: 2.3.1 Classification on the basis of Physicochemical Properties: Inert – not being explosive, oxidising, flammable. Use of this material as a blasting abrasive may generate dust so risk management measures may be needed. 2.3.2 Classification on the basis of health effects: When product is wetted or in contact with sweat, tears, mucus membrane highly alkaline solutions will be liberated. Skin Wet product can cause skin disease. Irritant contact dermatitis is caused by the combination of the wetness, alkalinity and abrasiveness of the product. Allergic contact dermatitis may be caused by individual sensitivity to rare earth metals (eg. chromium compounds). “Cement like” alkaline burns, a form of ulceration, may result from contact with this product. Eyes Wet product can cause irritation, inflammation or “cement like” burns on contact with eyes. Ingestion / Inhalation Swallowing of small amounts of product is unlikely to cause any significant reaction. Large amounts can cause irritation of the stomach and intestinal tract / respiratory tract. 2.3.3 Classification on the basis of environmental effects: Uncontrolled release to watercourses will cause discolouration and raised alkalinity to the aquatic environment that may be injurious to some species of macro and micro vertebrates and invertebrates.
