EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE!

 •INHALATION Abdominal cramps. Cough. Diarrhoea. Laboured breathing. Nausea. Sore throat. Vomiting. Symptoms may be delayed (see Notes).
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Redness. After delay skin burns.
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES Redness. Pain.
Safety spectacles 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 cramps. Diarrhoea. Nausea. Vomiting.
Do not eat, drink, or smoke during work. Wash hands before eating.
Give one or two glasses of water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Sn) 0.1 mg/m as TWA; 0.2 mg/m as STEL; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2008).
MAK: (as Sn) 0.004 ppm 0.02 mg/m;
Peak limitation category: I(1);
skin absorption (H);
Carcinogen category: 4; Pregnancy risk group: C
(DFG 2009).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes , the skin . Inhalation of the aerosol may cause lung oedema (see Notes). The substance may cause effects on the thymus , resulting in depression of the immune function.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Boiling point: 173C
Melting point: <-45C
Relative density (water = 1): 1.17 at 20C
Solubility in water:
poor
Vapour pressure, Pa at 20C: 0.001
Flash point: 190C c.c.
Octanol/water partition coefficient as log Pow: 3.19
ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in fish and in molluscs. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. through inappropriate disposal.
N O T E S
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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
