TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with combustibles and reducing agents.
Water in large amounts.
EXPLOSION Risk of fire and explosion on contact with combustible substances and reducing agents.

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness.
Protective gloves.
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
 •EYES Redness. Pain.
Safety goggles, or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION Abdominal pain. Diarrhoea. Nausea. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. (Extra personal protection: P3 filter respirator for toxic particles.)
Separated from combustible and reducing substances, powdered metals and incompatible materials. See Chemical Dangers.

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes . The substance is a strong oxidant and reacts violently with combustible and reducing materials. Reacts violently with aluminium, disulfur dibromide, arsenic, carbon, copper, metal sulfides, phosphorus and sulfur, causing fire hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the kidneys and central nervous system when ingested , resulting in renal failure, respiratory depression and hearing loss. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is possibly carcinogenic to humans.
