TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
AFFF, powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).
In case of fire: keep drums, etc., cool by spraying with water.
 
EXPOSURE


INHALATION Cough. Drowsiness. Sore throat.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
SKIN Dry skin. Redness.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
EYES Redness.
Safety spectacles.
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. Rest. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Collect leaking and spilled liquid in sealable metal containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. (Extra personal protection: self-contained breathing apparatus).
Fireproof. Cool. Keep in the dark. Keep in a well-ventilated room. Store only if stabilized.

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

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
The substance can readily form explosive peroxides if unstabilized and explode on shaking.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 250 ppm; 1040 mg/m3; STEL: 310 ppm; 1300 mg/m3 (ACGIH 1995-1996).


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system. Exposure above the OEL could cause lowering of consciousness.

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

ENVIRONMENTAL
DATA
N O T E S
Usually contains p-benzylaminophenol as stabilizer. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Check for peroxides prior to distillation; eliminate if found.
