EC number: 270-659-9 | CAS number: 68475-76-3 A complex combination of finely divided inorganic particles separated from the exit gases formed during the manufacture of Portland cement. The flue dust consists of uncalcined raw materials along with partially calcined materials. Some Portland cement clinker is usually included. The major constituents of kiln dust are calcium carbonate, clays, shales, quartz and sulfate salts. The following materials may also be present:@Dolomite@Ca(OH)2@Feldspars@CaSO4@Fly ash@KCl@Iron oxides@K2CO3@CaF2@K2SO4@CaO@Na2SO4@Glasses of SiO2, Al.s@Portland cement chemicals [659

First-aid measures
Following skin contact
For dry Portland cement clinker, remove and rinse abundantly with water.
For wet/damp Portland cement clinker, wash skin with plenty of water.
Remove contaminated clothing, footwear, watches, etc. and clean thoroughly before re-using them.
Seek medical treatment in all cases of irritation or burns.
Following contact with eyes
Do not rub eyes in order to avoid possible corneal damage by mechanical stress.
Remove contact lenses if any. Incline head to injured eye, open the eyelids widely and flush eye(s) immediately by thoroughly rinsing with plenty of clean water for at least 20 minutes to remove all particles. Avoid flushing particles into uninjured eye. If possible, use isotonic water (0.9% NaCl). Contact a specialist of occupational medicine or an eye specialist.
Following ingestion
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 anti poison centre.
Fire-fighting measures
Flue Dust is non-flammable, non-combustible and non-explosive and will not facilitate or sustain the combustion of other materials.
It poses no fire-related hazards. No need for special protective equipment for fire fighters.
Accidental release measures
Avoid contact with skin and eyes, keep dust levels to a minimum, and ensure that sufficient ventilation or suitable respiratory protective equipment is used.
Collect spilled material and use it.
Use dry cleanup methods such as vacuum clean-up or vacuum extraction (Industrial portable units, equipped with high efficiency particulate filters (HEPA filter) or equivalent technique), which do not cause airborne dispersion. Do not use compressed air.
Ensure that the workers wear appropriate personal protective equipment and prevent dust from spreading.
Avoid inhalation of Portland cement clinker dust and contact with skin. Place spilled material in a container and use it.
Handling and storage
Measures to prevent aerosol and dust generation: Do not sweep. Use dry cleanup methods such as vacuum clean-up or vacuum extraction, which do not cause airborne dispersion.
Do not handle or store near food and beverages or smoking materials.
In dusty environment, wear dust mask and protective goggles.
Use protective gloves to avoid skin contact.
Flue Dustr should be stored under waterproof, dry (i.e. with internal condensation minimised) conditions, clean and protected from contamination.
Engulfment hazard: Flue Dust can build-up or adhere to the walls of a confined space. The substance can release, collapse or fall unexpectedly. To prevent engulfment or suffocation, do not enter a confined space, such as a silo, bin, bulk truck, or other storage container or vessel that stores or contains Flue Dust without taking the proper safety measures.
Do not use aluminium containers due to incompatibility of the materials.

Exposure controls / personal protection
Measures to reduce generation of dust and to avoid dust propagating in the environment such as dedusting, exhaust ventilation and dry clean-up methods which do not cause airborne dispersion.
General: Do not eat, drink or smoke when working with Flue Dust to avoid contact with skin or mouth.
Before starting to work with Flue Dust, apply a barrier creme and reapply it at regular intervals.
Immediately after working with Flue Dust or Flue Dust containing materials, workers should wash or shower or use skin moisturisers.
Remove contaminated clothing, footwear, watches, etc. and clean thoroughly before re-using them.
Eye protection/face
Wear approved glasses or safety goggles according to EN 166 when handling dry or wet Flue Dust to prevent contact with eyes.
Skin protection
Use impervious, abrasion and alkali resistant gloves (made of low soluble Cr (VI) containing material) internally lined with cotton, boots, closed long-sleeved protective clothing as well as skin care products (including barrier creams) to protect the skin from prolonged contact with wet Flue Dust. Particular care should be taken to ensure that wet Flue Dust does not enter the boots.
Respiratory protection
When a person is exposed to dust levels above exposure limits, use appropriate respiratory protection. It should be adapted to the dust level and conform to the relevant EN standard.
Stability and reactivity
When mixed with water, Flue Dust will harden into a mass that is not reactive under normal environment.
Flue Dust is stable as long as it is properly stored. It should be kept dry. Contact with incompatible materials should be avoided.
Wet Flue Dust is alkaline and incompatible with acids, with ammonium salts and with aluminium, copper and their alloys. Flue Dust dissolves in hydrofluoric acid to produce corrosive silicon tetrafluoride gas. Flue Dust reacts with water to form silicates and calcium hydroxide. Silicates in clinker react with powerful oxidizers such as fluorine, boron trifluoride, chlorine trifluoride, managanese trifluoride, and oxygen difluoride.
Flue Dust will not decompose into any hazardous products.
Disposal considerations
Disposal should be in accordance with local and national legislation.
