TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE
Inhalation	Cough. Sore throat.	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.
Eyes	Redness. Pain. Blurred vision.	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. Vomiting. Diarrhoea. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into plastic containers; if appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment. Personal protection: P2 filter respirator for harmful particles.	UN Hazard Class: 8 UN Pack Group: III

EMERGENCY RESPONSE	STORAGE
Transport Emergency Card: TEC (R)-80S1773.	Separated from strong bases and incompatible materials. See Chemical Dangers. Dry. Well closed.

IMPORTANT DATA

Physical State; Appearance
BLACK TO BROWN HYGROSCOPIC CRYSTALS.

Chemical dangers
The substance decomposes on heating above 200°C producing toxic and corrosive gases including chlorine and hydrogen chloride. The substance decomposes on contact with water producing hydrogen chloride. The solution in water is a medium strong acid. Reacts violently with alkali metals, allyl chloride, ethylene oxide, styrene and bases causing explosion hazard. Attacks metal forming flammable/explosive gas (hydrogen - see ICSC0001).

Occupational exposure limits
TLV: (soluble iron salts, as Fe) 1 mg/m³; (ACGIH 2004).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory tract. Corrosive on ingestion.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 37°C (see Notes) Density: 2.9 g/cm³ Solubility in water, g/100 ml at 20°C: 92 (reaction) Vapour pressure, Pa at 20°C: negligible	The substance is harmful to aquatic organisms.

NOTES

UN number 1773 corresponds to the anhydrous form; UN number 2582 corresponds to the solution.
The apparent melting point caused by loss of crystal water is given.
Transport Emergency Card: TEC (R)-80GC1-II+III, corresponds to the solution.
Flores martis and molysite are common names.
