TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. The substance may ignite combustible materials. Many reactions may cause fire or explosion.  NO contact with combustible substances or reducing agents. NO contact with hot surfaces.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION Risk of fire and explosion on contact with heat or metal catalysts.    In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
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 .

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. 

Occupational exposure limits
TLV: 1ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: 0.5 ppm, 7.1 mg/m³; Carcinogen category: 4; Peak limitation category: I(1); Pregnancy risk group: C; (DFG 2005). 

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

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

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. 

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.
