Signal word

Danger STOT SE3: May cause respiratory irritation, Eye damage 1, Skin Sensitisation 1, Skin Irritation 2. STOT RE1: If the crystalline silica (fine fraction) concentration is equal to or greater than 10%. H315, H317, H318, H335, H372 STOT: Specific Target Organ Toxicity. SE; Single Exposure; RE; Repeated Exposure. (See section 15 for more detailed descriptions) Wet concrete can cause serious alkali burns if in direct contact with skin or eyes. Skin: Alkali burns, a form of skin ulceration, may result from contact with freshly mixed concrete. Contact with strongly alkaline solutions such as concrete can initially cause nerve damage. Chemical burns may occur without the person being aware because they do not feel any pain. Contact with wet cement mixes such as wet concrete can cause skin disease. Irritant contact dermatitis is caused by the combination of the wetness, alkalinity and abrasiveness of the ready-mixed concrete. Allergic contact dermatitis may be caused by individual sensitivity to chromium compounds in cement. Eyes: Wet concrete in contact with eyes can cause irritation, inflammation or serious alkali burns, which may lead to blindness. Ingestion: Swallowing small amounts of fresh concrete is unlikely to cause any significant reaction. Larger amounts can cause irritation of the stomach and intestines. Inhalation Wet concrete is not likely to create dust, but respirable dust may be released by the surface treatment and cutting or drilling of hardened concrete. If inhaled in excessive quantities over a prolonged period or extended period, respirable dust can constitute a long-term health hazard. Dusts containing Respirable Crystalline Silica* (quartz) present a greater hazard. Long-term exposure to respirable dust can lead to respiratory system damage and disease. Respirable crystalline silica has been associated with the lung disease silicosis. The quartz content of the product will vary, and is related to the type of aggregate used in the production of the concrete. Advice on the quartz content and other chemical information is available from the supplying unit. *Any references to respirable silica in this document only apply if hardened concrete is cut, drilled, milled or planed.
