EXPLOSION


EXPOSURE See EFFECTS OF LONG-TERM OR REPEATED EXPOSURE.
AVOID EXPOSURE OF (PREGNANT) WOMEN! PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

•INHALATION
Local exhaust or breathing protection.
Fresh air, rest.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES

PHYSICAL STATE; APPEARANCE:
RED TO YELLOW CRYSTALS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
Reacts violently with aluminium powder. On heating, toxic fumes are formed.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as Pb 0.05 mg/m3 as TWA; A3; BEI issued (ACGIH 2005).
MAK: as Pb (Inhalable fraction)
Carcinogen category: 2 Germ cell mutagen group: 3A
(DFG 2006).


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:


EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , bone marrow , central nervous system , peripheral nervous system and kidneys , resulting in anaemia, encephalopathy (e.g., convulsions), peripheral nerve disease, abdominal cramps and kidney impairment. This substance is probably carcinogenic to humans. Causes toxicity to human reproduction or development.
