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.
NO open flames.
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION see Ingestion.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN Redness. Pain.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Redness.
Safety goggles 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 Blue lips or finger nails. Blue skin. Confusion. Dizziness. Headache. Nausea.
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
WHITE TO BROWN HYGROSCOPIC CRYSTALS

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing corrosive fumes . The substance is a weak acid. Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quicklywhen dispersed

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the skin . The substance may cause effects on the blood , resulting in the formation of methaemoglobin. Inhalation may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL
PROPERTIES
Decomposes below boiling point at 57C
Melting point (decomposes): 57C
Relative density (water = 1): 1.9
Solubility in water, g/100 ml: (good)
ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.
N O T E S
Depending on the degree of exposure, periodic medical examination is suggested. 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 is therefore essential. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
