CNP PM NF cement

Where significant accidental inhalation occurs, take the individual into the fresh air. The throat and nostrils should clear themselves. Consult a doctor if persistent irritation occurs, or in case the subsequent appearance of discomfort, coughing or any other symptoms.

Symptoms: Cement may irritate the throat and respiratory tract. Coughs, sneezing and respiratory discomfort may appear in circumstances where the limit value of occupational exposure is exceeded.

If the cement is dry: Wipe off as much as possible. Rinse with plenty of water. If the cement is mixed: Rinse with plenty of water. Remove clothing, shoes, watches and other objects that have become contaminated and clean thoroughly before reuse. In case of irritation, redness or burns, consult a doctor.

Symptoms: Contact with the skin: of dry cement in contact with slightly wet skin or exposure to wet or mixed cement may lead to thickening of the skin and the appearance of fissures or cracks. Prolonged contact combined with abrasions may cause severe burns.

Do not rub in order to avoid further damage to the cornea. If need be, remove contact lenses, then rinse immediately with copious amounts of clean water for at least 15 minutes, keeping the eyelids wide apart in order to eliminate any residue. If possible, use isotonic water (0.9% NaCL). Consult an occupational doctor or ophthalmologist.

Symptoms: Direct contact may damage the cornea due to rubbing, may cause immediate or subsequent irritation or inflammation. Larger quantities of dry cement or splashes of mixed cement may lead to consequences ranging from moderate irritation (conjunctivitis or blepharitis) to chemical burns and blindness.

In case of significant accidental ingestion do not induce vomiting. If the person is conscious, rinse their mouth with water. Call a doctor immediately or an anti-poison centre.

Symptoms: Burns to mouth, oesophagus and gastrointestinal tract, nausea, vomiting.

Any extinguishing agent can be used

Cement is neither combustible, nor explosive and will not aid or feed the combustion of other materials

Do not allow product to spread into the environment Do not pour down the drains, into the sewer system or into water courses (eg. streams)

Clean up dry cement using methods that do not cause the dispersion of the dry product into the air, for example: - suction cleaners (portable industrial strength, equipped with an effective air particle filter (HEPA filter) or some other equivalent technique) - floorcloths, damp brushes or hosepipe with spray attachment (set to "fine spray" in order to avoid dispersing the product into the air) Recover the resulting slurry If the product cannot be removed dry using a suction cleaner or made wet, make sure that staff responsible for sweeping it up dry wear appropriate individual protection equipment and that further dispersion of dust is prevented Place the recovered product in a closed container. Arrange for its collection before disposing of it as indicated in section 13 Recover waste cement and place it in a closed container. Wait until it sets and becomes solid before disposing of it as indicated in section 13

Materials: suction cleaners (portable industrial strength, equipped with an effective air particle filter (HEPA filter) or some other equivalent technique), floorcloths, damp brushes or hosepipe with spray attachment

Avoid the formation or spread of dust in the atmosphere; Avoid contact with skin and eyes; Do not breathe dust

Bulk cement must be stored in silos that are watertight, dry, clean and protected from all contamination. Cement in bags must be stored with the bags closed, off the ground, and in a cool and dry atmosphere, protected from excessive draught which would lead to a deterioration of the quality of the product

Do not eat, drink or smoke while handling cement in order to avoid all contact with the skin or mouth. Wash your hands immediately after handling cement or products containing cement. Remove clothing, shoes, watches and other contaminated objects and wash them separately and thoroughly before reuse

Ensure good ventilation of the work station

Protective gloves made from waterproof nitrile rubber or neoprene, using material containing little soluble Cr (VI), with a cotton lining. These gloves must be waterproof and resistant to wear and alkalis. Gloves are only effective as long as cement particles do not penetrate between the gloves and the skin. The protective gloves to be used must comply with the specifications of EC directive 89/686/EEC and the resultant standard EN 374

Handling of dry or mixed cement: Approved goggles or watertight goggles complying with NF EN 166

Suitable anti-dust mask. Filter type FFP2

Protective clothing with long elasticated cuffs and closed neck. Boots . Take care that mixed cement does not penetrate inside your boots. For work where kneeling in involved, waterproof knee-pads are required. As far as possible, avoid kneeling on mortar or fresh concrete (eg: when concreting a floor, laying screed, ...)

Take all necessary precautions to avoid the accidental release of the product outside, due to the rupture of containers or transfer systems

Dry cement remains stable as long as it is stored correctly (see section 7) and is compatible with most other building materials. When mixed with water, cement hardens into a stable mass which does not react in ordinary environments. Wet cement is alkaline and incompatible with acids, with ammonium salts, with aluminium or other non-noble metals. Cement dissolves in hydrofluoric acid to produce corrosive silicon tetrafluoride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates in cement react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, manganese trifluoride, and oxygen difluoride

To our knowledge, the product does not present any particular risk. When mixed with water, the product will harden into a stable mass that is not reactive in normal environments

None, to our knowledge

Damp may cause cement to harden (formation of lumps) and a loss of quality of the product

Aluminium ( Formation of hydrogen in mixed cement in case of uncontrolled used ), Acids, Ammonium salts

None, to our knowledge. Cements do not break down into dangerous sub-products and are not subject to polymerization
