SECTION 4   

FIRST-AID MEASURES

In case if inhalation

Remove casualty to fresh air and keep at rest. Inform doctor.

In case of contact with Skin

:

After contact with the skin, wash immediately with plenty of water. Seek medical advice if skin irritation persists.

In case of contact with eyes

:

On contact with eyes, rinse  immediately  with plenty of water and seek medical advice.

In case of ingestion

:

Advice to doctor   

:

Symptoms: shortness of breath, nausea, unconsciousness, Hazards, danger of lung edema. Treatment: If swallowed, wash out the stomach and administer active charcoal. It may be necessary to administer common salt solution  if necessary (2-3 tablespoons/500 ml water). Not applicable to small children.  It may be necessary to administer oxygen.  Keep under medical observation for at least 48 hours.

Further information

:

Take off all contaminated clothing immediately and dispose of it safely; precautions to be taken when administering first aid; in cases of shortage of breath, administer oxygen treatment. Place baths of Luke warm  water  in readiness.

FIRE FIGHTING MEASURES

Extinguishing media

:

Dry powder, dry sand

Unsuitable extinguishing

:

Water, foam media

Special exposure hazards

:

Dangerous fumes are released during fire.

Dangerous

:

Sulphur dioxide (SO₂), Phosphorus oxides (e.g. phosphorus decomposition products pentoxide).  Reacts with water, forming phosphorus acid (H₃PO₄), phosphoric acid  and hydrogen sulfide.

Equipment for firefighters

:

In case of fire, wear a self-contained breathing apparatus and protect clothing.

Specific extinguishing

:

Combustion residues must be disposed of in accordance with the procedure and regulations applicable.

SECTION 6

ACCIDENTAL RELEASE MEASURES

Personal precaution

:

Do not inhale. Avoid contact with eyes and skin. Use personal protection equipment.

Environmental precaution

:

Avoid release into the sewage network or the aquatic environment.

:

SECTION 7

HANDLING AND STORAGE

Handling

:

Avoid dust formation and accumulation. Ensure good ventilation. When handling large amounts, take precautionary measures against build-up of electrostatic charge.  Avoid impact, friction and build-up of electrostatic charge; risk of ignition. Earth tanks and plant properly. Use antistatically treated equipment. Instructions for protection against fire and explosion; keep away from sources of ignition-no smoking. Take preventive measures against build-up of electrostatic charge (earth during transfer).  Avoid jolts and friction. Avoid dust formation.

Storage 

:

Keep only in the original container in a cool, well-ventilated place away from acids. Storage stability: storage time <24 months.

Requirements for packing

SECTION 10

STABILITY AND REACTIVITY

Stability 

:

Shock-sensitive.

Circumstances to avoid

:

Risk of dust explosion; spontaneously decomposes, emitting, hydrogen sulphide, on contact with water; reactions with acids, alkalis and oxidizing agents; formation of toxic and flammable hydrogen sulphide. Danger of explosion (Explosion limits of hydrogen sulphide in air  4.3 - 46%)

Substances to avoid

:

Water

Dangerous decomposition products

:

Hydrogen sulphide (H₂S)

SECTION 11

TOXICOLOGICAL INFORMATION

:

Topical effects

:

Other effects

:

Toxic when inhaled in aerosol form. Toxic effects on the central nervous system, with cramps, breathing problems and unconsciousness. Inhalation can cause damage to the respiratory system and lungs. The   toxicity data for the pure substance cannot be determined, because the product decomposes or reacts spontaneously in the presence of moisture. The specified data relate to the decomposition or reaction products.

SECTION 12

ECOLOGICAL INFORMATION

Very small amounts of the product are harmful to fish and bacteria.  For this reason it should be separated by sedimentation followed by oxidation with chlorine bleach before discharge into the sewage network. When discharged into water, there is a risk that large amounts of hydrogen sulphide will form spontaneously.  The product decomposes spontaneously in water.  The ecological information thus relates to the effect of the decomposition products.

SECTION 13

DISPOSAL CONSIDERATIONS

Method of disposal

:

Product can be disposed of in a special incineration facility after pre-treatment, provided the special waste regulations are complied with. Unknown emissions into the air must be eliminated by flue gas scrubbing.

Disposal of packaging

:

Corroded or soiled packaging must be disposed of in the same way as the product.

SECTION 14

TRANSPORT INFORMATION

Flammable powder ignites on friction avoid rough roads while driving. Cover drums with Tarpaulin to avoid contact of rain water/moisture. Incase of fire put it off with dry sand or carbon gas. Do not use water to extinguish fire.  If affected by gas, move to dry space. Give soda water or stimulants like hot and strong tea or coffee. Unload drums carefully by using ramp.
