TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Gives off irritating or toxic fumes (or gases) in a fire.

Water spray, powder.
EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

•INHALATION
Avoid inhalation of fine dust and mist.
Fresh air, rest.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES Redness.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALS OR GREY TO WHITE POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes slowly on contact with bases .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Germ cell mutagen group: 3A;
(DFG 2005).


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

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
