TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.	NO contact with combustibles and reducing agents.	In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION	Risk of fire and explosion on contact with reducing agents.

EXPOSURE		PREVENT DISPERSION OF DUST!
•INHALATION	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN			First rinse with plenty of water, then remove contaminated clothes and rinse again.
•EYES	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION	Abdominal pain. Blue lips or fingernails. Blue skin. Confusion. Convulsions. Dizziness. Headache. Nausea. Unconsciousness.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
HYGROSCOPIC COLOURLESS OR WHITE CRYSTALS .

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance is a strong oxidant and reacts with combustible and reducing materials, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.

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

INHALATION RISK:
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
May cause mechanical irritation tothe eyesandthe respiratory tract. The substance may cause effects on the blood when ingested , resulting in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Decomposes below boiling point at 330°C

Solubility in water: very good

ENVIRONMENTAL
DATA

N O T E S

Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Rinse contaminated clothes (fire hazard) with plenty of water. The recommendations on this Card also apply to Magnesium nitrate hexahydrate (CAS 13446-18-9) which is available commercially.
