ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

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

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION


EXPOSURE
AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN! AVOID EXPOSURE OF BREASTFEEDING WOMEN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Loss of movement co-ordination. Headache. Tremor. Weakness.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED!
Protective clothing. Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.

WHITE CRYSTALS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On combustion, forms chlorine fumes andhydrogen chloride. The substance decomposes on contact with acids producing toxic fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Carcinogen category: 3B;
(DFG 2002).
OSHA PEL: none
NIOSH REL: Ca TWA 0.001 mg/m3 See Appendix A
NIOSH IDLH: Ca N.D. See: IDLH INDEX


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system and liver , resulting in impaired functions and liver impairment . The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the endocrine system . This substance is possibly carcinogenic to humans. Causes toxicity to human reproduction or development.

PHYSICAL
PROPERTIES

Sublimation point: 350°C
(decomposes)
Solubility in water, g/100 ml at 20°C: poor
Octanol/water partition coefficient as log Pow: 3.45

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur in fish, in mammals and in milk.

N O T E S

Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Consult national legislation.
