EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

•INHALATION Burning sensation. Cough. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
•SKIN Redness. Pain. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES Redness. Pain. Severe deep burns.
Face shield, 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. Burning sensation. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting (extra personal protection: P2 filter respirator for harmful particles).


ICSC: 0772 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:
WHITE CRYSTALLINE POWDER.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The solution in water is a medium strong acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of aerosol may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point: 206°C
Relative density (water = 1): 1.79
Solubility in water, g/100 ml at 20°C: 20.6
Flash point: 210°C o.c.
Auto-ignition temperature: 425°C
Octanol/water partition coefficient as log Pow: -0.76 (calculated)

ENVIRONMENTAL
DATA


N O T E S

The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
NFPA Code: H0; F1; R0
