Cementitious building materials in general

Seek fresh air. Dust should quickly be removed from throat and nose.

Symptoms: discomfort, coughing or persistent irritation

Remove dry product and rinse abundantly with water. Rinse wet product with plenty of water. Remove contaminated clothing, footwear, watches, etc. and clean these thoroughly before re-using them.

Symptoms: irritation or burns

Do not rub eyes dry. 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 % NaCl).

Symptoms: mechanical stress may cause additional damage to the cornea

Do not induce vomiting. If the person is conscious, wash out mouth with water and give plenty of water to drink.

The products are non-combustible and non-explosive and will not facilitate or sustain the combustion of other materials.

No special measures are required.

Wear protective equipment as described in section 8. Follow the advice for safe handling and use given in section 7.

The products should not penetrate the sewage water system, surface water or groundwater.

Dry product: Absorb spilled product and reuse, if possible. Use dry methods to clean, such as vacuum exhaust (portable devices with highly efficient filter systems (EPA and HEPA filters, EN 1822-1:2009) or equivalent techniques). Wet product: Clean up wet product and place into a container. Allow material to dry and solidify before disposal.

Wear dust respirator and protective goggles in dusty environment. Use protective gloves to avoid skin contact.

The products should be stored under dry (minimizing internal condensation), water-protected conditions, clean and protected from contamination.

Do not eat, drink, or smoke when working.

Not applicable.

Measures to prevent formation and spreading of dust, for example suitable ventilation systems and cleaning methods, which do not stir up dust. Specific technical installations (e.g., local exhaust ventilation, general ventilation) are recommended based on the exposure scenario (see table in 8.2.1). For professional use (PROC 19), process only in well-ventilated rooms or outdoors.

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 EN 166 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). If compliance with maximum allowable concentrations cannot be guaranteed by dust-limiting measures, particle-filtering half-masks of the type FFP (according to EN 149) must be used (see table in 8.2.2). General information can be found in Rule 112-190 of the DGUV. For manual and mechanical handling of ready-made cement paste, cement mortar and concrete, respiratory protective equipment is not required.

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 flowing in shoes or boots from above. Observe skin protection plan. Apply skin care products, in particular after work. General information can be found in Rule 112-195 of the DGUV.

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).

The product is stable, as long as it is properly stored (see section 7).

The product is a hydraulic material. When mixed with water, an intended reaction takes place. As a result, the product hardens and forms a solid mass, which does not react with its environment.

Wet product is alkaline and incompatible with acids, ammonium salts, aluminum, and other base metals. Here, hydrogen can be formed. The product dissolves in hydrofluoric acid, forming corrosive silicon tetrafluoride gas.

It should be kept dry. Contact with incompatible materials should be avoided.

acids, ammonium salts, aluminum, and other base metals, hydrofluoric acid, strongly oxidizing agents such as fluorides.

hydrogen, corrosive silicon tetrafluoride gas, calcium silicate hydrates, calcium aluminate hydrates and calcium hydroxide (formed with water).

Gather dryly. Label container. If possible, reuse material, avoiding dust exposure and observing date of expiry. In case of disposal, cure with water and dispose of as described under 'Products cured after water addition'.

Dispose of in strict accordance with local official directives. Do not dispose of in the sewage water system. Dispose of the cured products like of concrete waste and concrete sludge.
