First
aid / Fire fighting |
| Fire
|
Not combustible. The
substance may ignite combustible materials. Many
reactions may cause Fire or Explosion. |
NO contact with combustibles
or reducing agents. NO contact with hot surfaces. |
In case of Fire in the
surroundings: water in large amounts, water spray. |
| 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. |
Ventilation, local exhaust,
or breathing protection. |
Fresh air, rest. Half-upright
position. Refer for medical attention. |
| Skin
|
Corrosive. White spots.
Redness. Skin burns. Pain. |
Protective gloves. Protective
clothing. |
First rinse with plenty
of water, then remove contaminated clothes and rinse
again. Refer for medical attention. |
| Eyes
|
Corrosive. Redness.
Pain. Blurred vision. Severe deep burns. |
Safety goggles or face
shield. |
First rinse with plenty
of water for several minutes (remove contact lenses
if easily possible), then take to a doctor. |
| 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 |
Packaging
& Labelling |
| Ventilation. Wash away
spilled liquid with plenty of water. Do NOT absorb
in saw-dust or other combustible absorbents. Do
NOT let this chemical enter the environment. (Extra
personal protection: chemical protection suit including
self-contained breathing apparatus). |

data |
Physical State; Appearance
Colourless liquid.
Chemical dangers
The substance decomposes on warming or under influence
of light producing oxygen, which increases Fire
hazard. The substance is a strong oxidant and reacts
violently with combustible and reducing materials
causing Fire and Explosion hazard particularly in
the presence of metals. Attacks many organic substances,
e.g., textile and paper.
Occupational Exposure limits
TLV: 1 ppm; (as TWA) A3 (ACGIH 1999). |
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 20oC.
Effects of short-term Exposure
The substance is corrosive to the eyes and the skin.
The vapour irritates 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
Lungs may be affected by inhalation of high concentrations.
The substance may have effects on the hair, resulting
in bleaching. |
