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.
In case of fire in the surroundings: use appropriate extinguishing media.
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! STRICT HYGIENE!

 •INHALATION Cough. Sore throat. Wheezing. Laboured breathing.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN Redness. Burning sensation. Pain.
Protective gloves.
First rinse with plenty of water, then remove contaminated clothes and rinse again.
 •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 Nausea. Diarrhoea. Vomiting. Sore throat.
Do not eat, drink, or smoke during work. Wash hands before eating.
Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR WHITE POWDER

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance is a strong oxidant and reacts with combustible and reducing materials. The substance decomposes on heating producing toxic and corrosive fumes including ammonia , nitrogen oxides and sulfur oxides . If in solution, reacts violently with iron, powdered aluminium and silver salts. The solution in water is a medium strong acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as persulfates) 0.1 mg/m3 as TWA (ACGIH 2001).
MAK: sensitization of respiratory tract and skin (Sah); (DFG 2006).


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 quicklyon spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract Inhalation of dust may cause asthma-like reactions.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged inhalation exposure may cause asthma. Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. May cause general allergic reaction, like urticaria or shock.

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

Rinse contaminated clothes (fire hazard) with plenty of water. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Do NOT take working clothes home.
