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 open flames.	In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION	Risk of fire and explosion.

EXPOSURE		STRICT HYGIENE!
Inhalation	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes		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. Diarrhoea. Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Personal protection: P2 filter respirator for harmful particles. Do NOT let this chemical enter the environment.	UN classification UN Hazard Class: 5.1 UN Pack Group: III

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-51G02-I+II+III	Separated from combustible and reducing substances.

IMPORTANT DATA
Physical State; Appearance DEEP VIOLET CRYSTALS Chemical dangers The substance is a strong oxidant and reacts with combustible and reducing materials. The solution in water is a weak acid. Occupational exposure limits TLV: (as Cr metal, Cr(III) compounds) 0.5 mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). MAK not established.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of short-term exposure The substance is irritating to the respiratory tract. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.
