PHYSICAL STATE; APPEARANCE:
ODOURLESS GRANULES OR POWDER IN VARIABLE COLOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance is a weak base in suspension in water.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of dust.

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

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
