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.

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

FERRIC CHLORIDE (anhydrous) ICSC: 1499
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BLACK TO BROWN HYGROSCOPIC CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating above 200C 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/m; (ACGIH 2004).
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
Evaporation at 20C 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
Melting point: 37C (see Notes)
Density: 2.9 g/cm
Solubility in water, g/100 ml at 20C: 92 (reaction)
Vapour pressure, Pa at 20C: negligible
ENVIRONMENTAL DATA
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.
