Cementitious building materials in general

Seek fresh air. Dust should quickly be removed from throat and nose. Consult a physician, should symptoms such as discomfort, coughing or persistent irritation occur.

Symptoms: Repeated inhalation of substantial amounts of the product dust over a prolonged period increases the risk of developing lung diseases.

Remove dry product and rinse abundantly with water. Rinse wet product agent with plenty of water. Remove contaminated clothing, footwear, watches, etc. and clean these thoroughly before re-using them. Seek medical treatment in all cases of irritation or burns.

Symptoms: Sustained contact with the product may cause irritation on damp skin (due to sweating or humidity). Contact of the product with damp skin may cause skin irritation, dermatitis, or severe skin damage.

Do not rub eyes dry, because mechanical stress may cause additional damage to the cornea. Where applicable, remove contact lenses and immediately rinse the eye, while open, under running water for at least 20 minutes in order to remove all particles. If possible, use isotonic eye-cleansing solution (0.9 % NaCI). Always consult an occupational physician or ophthalmologist.

Symptoms: Eye contact with the product (dry or wet) may cause serious and potentially irreversible eye damage.

Do not induce vomiting. If the person is conscious, wash out mouth with water and give plenty of water to drink. Get immediate medical attention or contact the poison information center.

Measures to prevent formation and spreading of dust, for example suitable ventilation systems (such as local exhaust ventilation or general ventilation) and cleaning methods, which do not stir up dust.

Wear waterproof, abrasion, and alkali-resistant gloves. Leather gloves are not suitable due to their water penetrability and can release chromate-containing compounds. For handling the products, special gloves for chemicals (Cat. III) are not required. Investigations have proven that nitrile impregnated cotton gloves (layer thickness of about 0.15 mm) provide sufficient protection over a period of 480 minutes. Change soaked gloves. Have spare gloves ready.

Use tight-fitting safety goggles according to DIN EN 166:2002 where dust is formed or in case of risk of spilling.

Use adequate respirator masks when there is a risk that exposure limit values are exceeded (e.g., during open handling of dry powder products). Particle-filtering half-masks of the type FFP (according to DIN EN 149:2009) must be used, such as FFP1, FFP2, or FFP3 masks depending on the exposure scenario.

Wear tight footwear and long-sleeved clothing. If contact with moist product cannot be avoided, protective clothing should also be waterproof. Take care that no moist product is running in shoes or boots from above. Observe skin protection plan. Apply skin care products, in particular after work.

Air: Compliance with dust emission limit values in accordance with the Technical Instructions on Air Quality. Water: Do not discharge the products into groundwater or wastewater systems in larger quantities. An increase in pH value is possible through exposure. At a pH value above 9, ecotoxicological effects may occur. Water directed or drained off into the wastewater system or surface water should therefore not lead to such a relevant pH value. Wastewater and groundwater regulations must be observed. Soil: Compliance with the German Federal Soil Protection Act (BBodSchG) and the German Federal Soil Protection and Contamination Ordinance (BBodSchV). No special control measures required.
