  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with combustible substances or reducing agents.  NO contact with combustible substances.    In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST! STRICT HYGIENE!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Laboured breathing. Sore throat. Wheezing.  Use 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 for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes Redness. Pain.  Wear 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 refer for medical attention. 
Ingestion Diarrhoea. Nausea. Sore throat. Vomiting.  Do not eat, drink, or smoke during work.  Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. Carefully collect remainder. Then wash away with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
WHITE CRYSTALS OR POWDER. 

Physical dangers
 

Chemical dangers
The substance is a strong oxidant. It reacts with combustible and reducing materials. Decomposes on heating. This produces toxic and corrosive fumes including sulfur oxides. Reacts violently with powdered metals and strong bases. The solution in water is a weak acid. 

Formula: Na2S2O8
Molecular mass: 238.1
Decomposes at 180°C
Density: 1.1 g/cm³
Solubility in water, g/100ml at 20°C: 55.6  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Inhalation of dust may cause asthma-like reactions. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

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 may cause asthma. May cause a general allergic reaction, such as urticaria or shock. 


Occupational exposure limits
TLV: 0.1 mg/m3, ppm, as TWA 

ENVIRONMENT
 

NOTES
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.
