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 explosionon contact withcombustible substances andreducing agents.

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

 •INHALATION Cough. Laboured breathing. Sore throat. Wheezing.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves. Protective clothing.
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 Diarrhoea. Nausea. Sore throat. Vomiting.
Do not eat, drink, or smoke during work.
Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers. Carefully collect remainder. Then wash away with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: P2 filter respirator for harmful particles.
Well closed. Separated from combustible and reducing substances, strong bases, powdered metals .

UN Hazard Class: 5.1
UN Packing Group: III

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR 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 sulfur oxides . Reacts violently with powdered metals and strong bases . The solution in water is a weak acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as persulfate) 0.1 mg/m³ as TWA; (ACGIH 2004).
MAK: sensitization of respiratory tract and skin (Sah); (DFG 2004).


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.

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 contact may cause skin sensitization. Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation exposure may cause asthma. May cause general allergic reaction, like urticaria or shock.

ENVIRONMENTAL
DATA

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. Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification, Emergency Response.
