TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

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


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

•INHALATION Cough. Sore throat. See Ingestion.
Ventilation (not if powder), local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
•SKIN Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES Redness.
Safety spectacles 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. Nausea. Diarrhoea. Vomiting. Weakness. Dullness. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest.

PHYSICAL STATE; APPEARANCE:
WHITE SOLID IN VARIOUS FORMS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Ba) 0.5 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: (as Ba) (Inhalable fraction) 0.5 mg/m3;
Peak limitation category: II(2);
(DFG 2004).


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the nervous system . Exposure could cause hypokalaemia , resulting in cardiac disorders and muscular disorders. Exposure may result in death.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES
