First
aid / Fire fighting |
| Fire
|
Highly flammable. Gives
off irritating or toxic fumes (or gases) in a Fire. |
NO open flames, NO sparks,
and NO smoking. |
Alcohol-resistant foam,
powder, AFFF, foam, carbon dioxide. |
| Explosion
|
Vapour/air mixtures
are explosive. |
Closed system, ventilation,
Explosion-proof electrical equipment and lighting. |
In case of Fire: keep
drums, etc., cool by spraying with water. |
 |
| Exposure |
|
Avoid all contact
! |
|
| Inhalation
|
Cough. Sore throat.
Shortness of breath. Laboured breathing. Headache.
Dizziness. Weakness. Nausea. Symptoms may be delayed
(see Notes). |
Ventilation, local exhaust,
or breathing protection. |
Fresh air, rest. Half-upright
position. Artificial respiration may be needed.
Refer for medical attention. |
| Skin
|
Redness. Skin burns.
Pain. |
Protective gloves. Protective
clothing. |
Remove contaminated
clothes. Rinse skin with plenty of water or shower.
Refer for medical attention. |
| Eyes
|
Pain. Redness. Blurred
vision. Blue haze and halo. Temporary loss of vision.
Severe deep burns. |
Face shield, or eye
protection in combination with breathing protection. |
First rinse with plenty
of water for several minutes (remove contact lenses
if easily possible), then take to a doctor. |
| Ingestion
|
Abdominal pain. Burning
sensation. Shock or collapse. |
Do not eat, drink, or
smoke during work. |
Rinse mouth. Do NOT
induce vomiting. Give plenty of water to drink.
Refer for medical attention. |
| Spillage disposal |
Packaging
& Labelling |
| Evacuate danger area!
Consult an expert! Ventilation. Remove all ignition
sources. Collect leaking liquid in sealable containers.
Absorb remaining liquid in sand or inert absorbent
and remove to safe place. Do NOT let this chemical
enter the environment. (Extra personal protection:
complete protective clothing including self-contained
breathing apparatus.) |

| Important
data |
Physical State; Appearance
Colourless liquid, With characteristic odour.
Physical dangers
The vapour is heavier than air and may travel along
the ground; distant ignition possible.
Chemical dangers
The substance decomposes on burning producing irritating
and toxic gases including nitrogen oxides. The substance
is a strong base, it reacts violently with acid
and is corrosive to aluminium, zinc, copper and
their alloys in the presence of moisture. Reacts
violently with strong oxidants causing Fire and
Explosion hazard. Attacks some forms of plastic,
rubber and coating.
Occupational Exposure limits
TLV: (as TWA) 1 ppm; (as STEL) 3 ppm; (skin), A4;
(ACGIH 2002).MAK: 1 ppm, 4.2 mg/m3; (DFG
2002).MAK: class Peak limitation category: I(2);
Pregnancy risk group: IIc; (2002)EU OEL: 2 ppm,
8.4 mg/m3 (as TWA); 3 ppm, 12.6 mg/m3
(as STEL); (skin); (EU 2002). |
Routes of Exposure
The substance can be absorbed into the body by inhalation,
through the skin and by ingestion.
Inhalation risk
A harmful contamination of the air can be reached
very quickly on evaporation of this substance at
20oC.
Effects of short-term Exposure
The substance is corrosive to the eyes, the skin
and the respiratory tract. Corrosive on ingestion.
Inhalation of the substance may cause lung oedema
(see Notes). The effects may be delayed. Medical
observation is indicated. The substance may cause
effects on the central nervous system. |

| Environmental
data |
| The substance is harmful
to aquatic organisms. |
| Notes |
The symptoms of lung
oedema 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.
Immediate administration of an appropriate inhalation
therapy by a doctor or a person authorized by him/her,
should be considered.
The odour warning when the Exposure limit value
is exceeded is insufficient. |
