CHLORODIPHENYLARSINE ICSC: 1526
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS, TECHNICAL PRODUCT: DARK-BROWN LIQUID.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes, including arsenic fumes and chlorine. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance may cause effects on the nervous system. Exposure at high levels could cause lowering of consciousness. Inhalation of high levels of its aerosol may cause lung oedema (see Notes). The effects may be delayed. Exposure at high levels may result in death.

PHYSICAL PROPERTIES
Boiling point (decomposes): 333C
Melting point: 38-44 C
Relative density (water = 1): 1.4 at 45C
Solubility in water, g/100 ml: 0.2 (poor)
Vapour pressure, Pa at 20C: 0.06
Relative vapour density (air = 1): 9.15
ENVIRONMENTAL DATA
The substance is very toxic 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 is therefore essential.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, EU classification.
