  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. The substance may ignite combustible materials. Many reactions may cause fire or explosion.  Risk of fire and explosion on contact with heat or metal catalysts.  NO contact with combustible substances or reducing agents. NO contact with hot surfaces.    In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Sore throat. Cough. Dizziness. Headache. Nausea. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Transient white spots. Redness. Skin burns. Pain.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Sore throat. Abdominal pain. Abdominal distension. Nausea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes under the influence of light. Decomposes on warming. This produces oxygen. This increases fire hazard. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. This generates fire and explosion hazard particularly in the presence of metals. Attacks many organic substances such as textiles and paper.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the eyes and skin. The vapour is irritating to the respiratory tract. Ingestion of this substance may produce oxygen bubbles (embolism) in the blood, resulting in shock. 

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of high concentrations may cause effects on the lungs. The substance may have effects on the hair. This may result in bleaching. 


Occupational exposure limits
TLV: 1 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: 0.71 mg/m3, 0.5 ppm; peak limitation category: I(1); carcinogen category: 4; pregnancy risk group: C 

ENVIRONMENT
The substance is toxic to aquatic organisms. 

NOTES
Rinse contaminated clothes (fire hazard) with plenty of water.
RTECS MX900000 refers to >90% solution; MX0887000 refers to >30% solution.
Other UN numbers: 2014 (hydrogen peroxide, aqueous solution 20-60%): hazard class 5.1, subsidiary hazard 8, pack group II; 2984 (hydrogen peroxide, aqueous solution 8-20%): hazard class 5.1, pack group III.
