TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Foam, powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 24°C explosive vapour/air mixtures may be formed.	Above 24°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT GENERATION OF MISTS!
INHALATION	Dizziness. Drowsiness. Headache.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
SKIN	Dry skin.	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	(further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

PACKAGING & LABELLING

Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Wash away remainder with plenty of water (extra personal protection: A filter respirator for organic vapour).

Fireproof. Separated from aluminum and strong oxidants.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance can form explosive peroxides. Reacts with aluminum forming flammable gas (Hydrogen - see ICSC # 0001). Reacts with strong oxidants, such as chromium trioxide causing fire hazard. Attacks some plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 100 ppm; 303 mg/m³ (as TWA) (ACGIH 1994-1995).
MAK: 100 ppm; 300 mg/m³ (1995).

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

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The vapour of this substance irritates the eyes. The substance may cause effects on the central nervous system. Exposure to high concentrations could cause lowering of consciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.
