EXPLOSION


EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Blue lips or finger nails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin MAY BE ABSORBED! Burning sensation. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes
Safety goggles, or 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. (See Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

4,4'-METHYLENE BIS(2-CHLOROANILINE) ICSC: 0508
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR LIGHT BROWN PELLETS

CHEMICAL DANGERS:
The substance decomposes on heating above 200°C or on burning producing toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. The substance is a weak base. Reacts with some metals such as aluminium, magnesium and potassium.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as TWA): 0.01 ppm; 0.11 mg/m^3 A2 (skin) (ACGIH 1998).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood, resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is probably carcinogenic to humans. May cause genetic damage in humans.
PHYSICAL PROPERTIES
Melting point: 110°C
Density: 1.44 g/cm^3
Solubility in water: none
Octanol/water partition coefficient as log Pow: 3.94
ENVIRONMENTAL DATA
In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms and plants.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Bisamine S, Bisamine A, Cuamine M, Cuamine MT, Curalin M, Curalon M, Curene 442, Diamet Kh are trade names.
