SECTION 5. FIREFIGHTING MEASURES

Flash Point: n/a
Suitable extinguishing media: Carbon dioxide, dry chemical powder, alcohol foam, water spray.
Water or foam may cause frothing.
Unsuitable extinguishing media : Water jet
Special hazards arising from the substance or mixture: Carbon monoxide and carbon dioxide and
Potassium oxides.
Advice for firefighters: In the event of a fire, wear full protective clothing and approved self-contained
breathing apparatus. Fight fire from a safe distance or protected location. Under
certain conditions a dust cloud of calcium stearate can explode when ignited by a
spark, flame or other ignition source. Must avoid generating dust to minimize risk

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal protective equipment:
Eye - Wear appropriate protective safety glasses
Skin – Wear appropriate protective gloves and clothing. Put on an appropriate respirator
Containment: Keep unnecessary personnel away. Eliminate all sources of ignition.
Do not allow the spilled product to enter sewers or open waterways
Clean-up Procedures: Dust deposits should not be allowed to accumulate on surfaces, as these may form
an explosive mixture if they are released into the atmosphere in sufficient concentration. Avoid the
generation of dust during the clean-up. Vacuum spills or cover with damp sand or saw-dust if sweep. No sparking tools should be used

SECTION 7. HANDLING AND STORAGE

Handling: Open packaging bag carefully, avoid spillage and dust formation and control ignition sources.
Use this product with adequate ventilation. Wash hands after handling.
Storage: Store in cool, dry place to avoid the effects of heat and moisture. Keep container tightly closed and properly labeled. Avoid exposure to sunlight, heat and spark. Ground all equipment containing material.
Minimize dust generation and accumulation. Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces. Dry powders can build static electricity charges when subjected to the friction of transfer and mixing operations. Provide adequate precautions, such as electrical grounding and bonding, or inert atmospheres.

Potassium

19 K 39.098300000 Potassium

See more Potassium products. Potassium (atomic symbol: K, atomic number: 19) is a Block S, Group 1, Period 4 element with an atomic weight of 39.0983. The number of electrons in each of Potassium's shells is [2, 8, 8, 1] and its electron configuration is [Ar] 4s¹. The potassium atom has a radius of 227.2 pm and a Van der Waals radius of 275 pm. Potassium was discovered and first isolated by Sir Humphrey Davy in 1807. Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water, it only occurs in nature in ionic salts. Potassium Bohr Model In its elemental form, potassium has a silvery gray metallic appearance, but its compounds (such as potassium hydroxide) are more frequently used in industrial and chemical applications. The origin of the element's name comes from the English word 'potash,' meaning pot ashes, and the Arabic word qali, which means alkali. The symbol K originates from the Latin word kalium.
