EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

•INHALATION
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles). Do NOT let this chemical enter the environment.
Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.

ICSC: 1062 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COLOURLESS CRYSTALLINE POWDER , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On heating, toxic fumes are formed.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 3 mg/m3 as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2008).
MAK: IIb (not established but data is available) (DFG 2008).
OSHA PEL: TWA 3 mg/m3
NIOSH REL: TWA 3 mg/m3
NIOSH IDLH: 1000 mg/m3 See: 115866


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

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:
The substance may have effects on the peripheral nervous system , resulting in impaired functions .
